Changed in Avid Media Composer v3.1 This release includes compatibility with Pro Tools v8.0 which includes the Video Satellite feature. For information, see the Video Satellite Guide provided by Digidesign. Fixed in Avid Media Composer v3.1 The following have been fixed in this release. Previously, advanced keyframes might not have been deleted from the Record window even if they had been deleted from the Advanced Keyframe editor. This may have occurred intermittently. This has been fixed. (Macintosh) Previously, you might have received assertion or bus errors when consolidating MXF media or performing an AAF export. This has been fixed. Previously, the memory usage would climb when opening the Advanced Keyframe parameter graph and switching from one clip to another. This has been fixed. When in Effects Mode, if you dragged a wire frame, you might have experienced low memory conditions. This has been fixed. Reverse play was not working properly when in MultiCamera mode. This has been fixed. Previously, memory reporting was incorrect on the Macintosh. This has been fixed. EDL Manager might have crashed when trying to create events from clips containing motion effects. This has been fixed. FilmScribe XML data stored in master clips was not appearing in lists following an Autosync. This has been fixed. 4

5 Fixed in Avid Media Composer v3.1 You might have received an overrun error when creating an Assemble Weblist while Pullin Source was enabled in FilmScribe. This has been fixed. (Macintosh) You might have received a DISK_FILE_NOT_FOUND error when attempting to create a WebList with FilmScribe. This occurs if you have an illegal character in the sequence name. You will now receive an error message indicating you have an illegal character in the sequence name and advising you to rename the sequence title in the CutList or ChangeList tool. You might have received a MainThread error when attempting to open a bin containing footage in FilmScribe. This has been fixed. FilmScribe was creating lists with missing data. This has been fixed. You might have experienced a memory leak when using MultiCamera mode with editing applications using Nitris DX. You might have also experienced memory leaks with Software only editors or editing applications using Adrenaline. (Macintosh) You might have received Segmentation fault errors while using JKL. This has been fixed. QuickTime and 7.5 causes washed out video if you use Motion JPEG-B, Avid recommends that you use the Avid codecs when using these versions of QuickTime. You can capture or import indexed media from an external drive, that was attached to a Macintosh Power PC, without causing it to rescan and index again when you reconnect the drive to a Macintosh or Windows Intel machine or vice versa. In 1080p24 projects running Adrenaline hardware, audio and video might have been out of sync by 2 frames. This has been fixed. You might have received Rational Overflow errors when trimming advanced keyframe effects. This has been fixed. Previously, deleting Matte Keys from bins left the LRELE8-A files on the Avid Unity ISIS workspace. This has been fixed. (Nitris and Adrenaline) Previously, you might have seen a slight vertical line down the right side of the image from HD component output. This has been fixed. You might have experienced audio crackle on output after toggling between 4 and 8 channels. This has been fixed. 5

6 During playback, you might have received Overrun on transmitting Midi data errors if a Command 8 was turned On. This has been fixed. You might have received Bus Error on Main Thread errors when performing a Dual rolling trim. This has been fixed. Batch Imported clips (media created from Meridien systems) might have stuttered during playback. This has been fixed. Exporting AAF caused errors when all tracks were selected. This has been fixed. Performing Send To QuickTime on the Macintosh was not working properly. This has been fixed. Occasionally, when working with Matte key layers, parts of the motion path display would not appear if the path was writing over itself. This has been fixed. When using EDL Mgr: v24.05 motion effects did not conform properly. This has been fixed. Changed in Avid Media Composer v3.0.5 The following features have been added to this release of the editing application. You can select multiple segments on enabled tracks using the multiple segment selection buttons. See Selecting Multiple Segments on page 7. You can now generate reports on sequence and clip information. See Sequence and Clip Information Summary on page 7 and Creating a Summary of Effects and Source Information on page 8. You can disable the locator edit window. See Disabling the Locator Edit Window on page 12. XDCAM HD 50mb is now supported with this release. See XDCAM Formats and Resolutions on page 14 and Working with XDCAM HD Media on page 14. (Macintosh) XDCAM Workflow change. See XDCAM Batch Importing Workflow Change on page 15. With this editing application release we support Grass Valley K2 using the Grass Valley K2 templates for digital cuts using insert edit. 6

7 Changed in Avid Media Composer v3.0.5 Selecting Multiple Segments Instead of lassoing segments in the Timeline to edit, you can select multiple segments on enabled tracks quickly by using the multiple segment selection buttons in the Edit tab of the Command palette. This allows you to select segments to the left or right of the position indicator, or to select all segments within In and Out marks. The multiple segment edit buttons also appear in the Timeline top toolbar if you create a new user profile (for information on creation user profiles, see Managing User Profiles in the Help). n When you use the multiple segment selection buttons, your Avid editing application switches to Segment Mode (the default is Lift/Overwrite Segment Mode). If your application is already in Segment Mode, Lift/Overwrite or Extract/Splice-In Mode does not change. If the application is in Effect Mode, no change in the working mode occurs. You can also use the Shift key to add segments on enabled tracks to the current selection. To select segments on enabled tracks using the multiple segment selection buttons: 1. Move the position indicator to the first or last segment you want to select. 2. Select Tools > Command Palette, and click the Edit tab. 3. Do one of the following: t Click the Select Left button to select segments under the position bar and all segments to the left. t Click the Select Right button to select segments under the position bar and all segments to the right. t Click the Select In/Out button to select segments intersecting In and Out marks if both marks are present. If there is only an In mark or an Out mark in the Timeline, or no In and Out marks, the Select In/Out button selects all segments under the position bar. Sequence and Clip Information Summary You can generate a report to display information about the contents of a sequence or clip. For example, you can generate a list of the types of effects in your sequence or where a particular effect is located. You can also create a clip summary or a source summary. This allows you to display a list of clip names, tape names, offline clips, and import path locations of imported clips contained in your selection. 7

8 You can access this functionality from the Source monitor, the Record monitor, or directly from a sequence or clip in a bin. The Sequence or Clip Information dialog box allows you to select your criteria and create a report that is displayed on either the Console window or in a text editor. You can then search the summary for the exact information you want. The following section gives examples of how these summaries can be helpful. Preparing for Online In preparing to move your sequence from an offline system to an online system, it s useful to run an effect summary and a source summary report. The Effect Summary displays a list of all effects, including a separate list of plug-ins used. The Source Summary is a list of all the tapes you need for recapture and a list of import paths for all imported graphics. Finding Specific Effects You use the Effect Summary and Effect Location Summary to find a particular effect. When you output the summary to a text editor, you use the Find option and Find Next option to cycle through all occurrences of the particular effect. In addition, the start or end timecode value for each occurrence can be entered into the Source/Record monitor to go to the start of the effect in the Timeline. For example, this can be helpful if you need to replace or modify a specific plug-in. Plug-in Information n An Effect Summary displays a list of effects found in the selection, including how many times the effect was used. For plug-ins loaded on your system, a section displays a summary of the plug-ins used, displaying the name, the vendor, the version and the ID of the plug-in. This can be helpful if you need to get a list of the plug-ins needed for online. If a plug-in is not loaded on your system when the summary is generated, the information displays unavailable effect, followed by the plug-in ID. The vendor and version number are not directly accessible. Creating a Summary of Effects and Source Information 8 You need to decide the following when you create a summary of effects, source information, or clip information: Determine the tracks or the material within the IN and OUT points you want to run the report on Choose the summary options you want information on: types of effects, location of effects, source information, or clip information Decide how you want to display the report: through the Console window or through a text editor

9 Changed in Avid Media Composer v3.0.5 To open the Sequence Info or Clip Info dialog box from the Source or Record monitor, do one of the following: t t With a sequence or clip loaded in a monitor, right-click the monitor and select Get Sequence Info (for a sequence) or Get Clip Info (for a clip). With a sequence or clip loaded in a monitor and the monitor selected, press Ctrl+I. To open the Sequence Info or Clip Info dialog box from a bin: t From a bin, right-click a sequence or clip and select Get Sequence Info (for a sequence) or Get Clip Info (for a clip). n n To determine the tracks or to use IN and OUT points: 1. Load a sequence in the Source or Record Monitor. 2. Decide which tracks or sections in the Timeline you want to run the report on by doing the following: t For specific tracks, select the track(s) in the Timeline. t Set IN and OUT points in the Timeline The advantage of loading a clip or sequence in a monitor allows you to choose tracks or IN and OUT points in the Timeline. Avid recommends that the tracks and IN and OUT points option should not be used when you select from a bin, these perimeters would not be controllable. 3. Right-click the monitor and select Get Sequence Info. The Sequence Info dialog box opens. 9

10 4. Select Generate Summary Info. 5. Choose from the following options: t If you selected specific tracks, click Enabled Tracks Only. t If you set IN and OUT points, click Use Marks. t If you want to run a report on the entire sequence regardless of tracks or marks, do not select either of these options. To choose the Info options (type of summary): 1. Once you have determined the track information, choose the type of report you want from the Summary Info Options section. Depending on the summaries you want information for, you can select one or more of those summaries below. 10

11 Changed in Avid Media Composer v3.0.5 Summary Option Suboption Description Create Effect Summary Create Effect Location List This displays the types of effects and how many were found in your sequence, the breakdown by effect type, and an effect plug-in summary. If you have selected individual tracks or selected IN and OUT points, only those effects that fall within those parameters appear. This displays the location of an effect. Depending on the criteria you selected, this displays track, start timecode, end timecode and effect name. Skip Non-Renderable Effects Skip Relationship-Only Color Correction Show Nested Effects Only Select this option if you do not want any non-renderable effects, such as pan/volume effects, to appear in the report. Select this option if you do not want any color correction effects with only relationships to appear in the report. Select this option if you want to only display the nested effects in your sequence. Effects that are nested inside of other effects show the parent effect track they are applied to with the track name in parentheses and indented to show the nesting relationship. Create Clip Summary or Create Source Summary Depending on the criteria you selected, a Clip Summary displays the number of clips found, type of clip, track, offline information, clip name, and clip Mob ID. A Source Summary displays the number of tape-based sources found, project name, tape name, tape ID, and tape Mob ID. It also displays a list of import paths for any imported clips, such as graphics. Offline Only Skip Non-Selected Clips in Group Clips Show Globally Unique Identifier (UID) Select this option if you want to display offline clips only. Select this option if you do not want any non-selected clips inside of a group clip to appear in the report. Select this option if you want to display the unique identifiers (Mob IDs) associated with the clips and sources in your sequence. 11

12 n To display the summary in a text file: 1. In the Summary Output Options area, select Output File. 2. If you want the text editor to open with the report, click Open File in A Text Window. The text editor on a Macintosh is the default TextEdit. The text editor on a Windows system is Word Pad. 3. Click OK. The Save Summary Output File As dialog box opens. 4. Use the default file name or rename the report and choose a folder to save the report to, click Save. This writes the report to a text file and opens a text editor. 5. (Option) Use the Find and Find Next command in the text editor to find all occurrences of a particular effect. n To display the summary in a Console window: 1. In the Summary Output Options area, select Console. 2. Click OK. The summary appears in the Console window. The Console window output options are limited by displaying a relatively small amount of information. The Console window also does not provide Find/Find Next capability. For larger summary reports Avid recommends you use the Output File option to save the summary to a text file. Disabling the Locator Edit Window n If you want to add locators without including comments, you can modify the behavior of the Locator edit window so that it does not open each time you create a new locator. This allows you to add locators quickly and then edit locator information later. This option is selected by default if you upgraded your Avid editing application from a previous version where the Disable Locators Popup option was selected. You can also disable the Locator edit window so it only opens from the Locators window. For information on accessing the Locator edit window, see Editing Locator Information on page

13 Changed in Avid Media Composer v3.0.5 To keep the Locator edit window from opening each time you add a locator: 1. Select Tools > Locators. The Locators window opens. 2. Select Disable Locator Popup when Adding from the Fast menu. The Locator edit window now does not open when you add locators. To keep the Locator edit window from opening: 1. Select Tools > Locators. The Locators window opens. 2. Select Disable Locator Popup Always from the Fast menu. The Locator edit window now does not open even if you double-click a locator. Editing Locator Information You can open the Locator edit window directly from a monitor, from the position indicator bar, or from the Locators window. In the Locator edit window, you can change the color of a locator, the locator name, or the text of the comment associated with a locator. To edit locator information in the Locator edit window: 1. Do one of the following: t Click the oval Locator icon in the Source or Record monitor. t Double-click the locator in the position indicator bar. t In the Locators window, right-click (Windows) or Ctrl+Shift+click (Macintosh) a locator item, and then select Edit Locator. t In the Locators window, select a locator, click the Fast menu, and select Edit Locator. The Locator edit window opens. 2. Do one or more of the following: t Select from the Color menu to change the color of the Locator icon. t Type a new locator name. t Enter new text or update the current text comment. 3. Click OK. 13

14 XDCAM Formats and Resolutions The following table lists the formats and resolutions available when you work with XDCAM media: Format/Resolution XDCAM HD (1080i/59.94, 1080i/50, 1080p/23.976): XDCAM HD 17.5 Mbits XDCAM HD 25 Mbits XDCAM HD 35 Mbits XDCAM HD 50 Mbits HDV 1080i (25 Mbits CBR) DVCAM: DV (NTSC and PAL) DV (PAL) MPEG IMX (NTSC and PAL): MPEG 30 MPEG 40 MPEG 50 Number of Audio Channels (maximum) 8 4 (for XDCAM 50) 4 8 MPEG-4 (proxy media) 4 or 8 Writeback is supported for 17.5, 25 and 35 Mbits/sec for 1080i 50, 1080i 59 and 1080p Working with XDCAM HD Media Your Avid editing application supports import of both proxy and high-resolution XDCAM HD media. XDCAM HD media, like other XDCAM media, is imported at the data rate at which it was recorded in one of the following resolutions: XDCAM HD LP (long play) (17.5 mb/sec) XDCAM HD SP (standard play) (25 mb/sec) XDCAM HD HQ (high quality) (35 mb/sec) XDCAM HD HQ (high quality) (50 mb/sec) 14

15 XDCAM Batch Importing Workflow Change However, when you create new media (create a title, render effects, transcode, and so on), you need to select a different resolution. The choice of resolutions is based on the project format. For example, in a 1080i/59.94 project, your can create media as DNxHD 220x, DNxHD 220, or DNxHD 145. You can play XDCAM HD media to a Client monitor or output a digital cut as Best Performance (yellow/yellow) or Draft Quality (yellow/green). However, if you are working with Adrenaline hardware, to play or output as Full Quality (green/green), you must transcode the XDCAM HD media to a DNxHD resolution or another compatible resolution. If you are using Nitris DX or Mojo DX, you can play out the back of HD-SDI. XDCAM Batch Importing Workflow Change With this release, if a customer tries to perform a batch import from proxy clips in an XDCAM workflow on the Macintosh platform, the Avid editing application might not see the disk at the beginning of the High Resolution import. If the user has to insert the disk when prompted at the beginning of a batch, the editing application will not see the disk. If the disk is already in the deck when the user is prompted for the first disk, the import will work properly. To workaround this, make sure the first disk is inserted in the deck prior to performing the batch import. If you are batch importing with multiple disks, each time you are prompted for another disk, insert the disk, cancel the batch import and select File > Mount All. Highlight the sequence and select Clip > Batch Import. Repeat for each new disk. Import Settings: Image Tab Changes The following table describes options available in the Import Settings: Image tab. Changes have been made to the Import Image Settings dialog options. These changes have been made to help clarify the image settings options. The old option name is listed followed by the new option in bold. 15

16 Option Aspect Ratio, Pixel Aspect (Image Size Adjustment) Description Controls the dimensions of imported images. The following options are available: 601/709, non-square (Image properly sized for current format): Select this option if the image is properly sized and formatted for the current project format: 720 x 480 (NTSC) or 720 x 576 (PAL). Also use this option for 720 x 540 images, or for other images that fit the 4:3 aspect ratio, or to maintain field data when you import two-field media that follows exact NTSC or PAL dimensions. Your Avid editing application converts the existing pixel dimensions, if necessary, so that the image fills the screen. HD projects use the ITU-R 709 color space instead of ITU-R 601. This is the default option. If the aspect ratio of the original frames does not match the 4:3 aspect ratio used by your Avid editing application, the imported frames might appear distorted. For best full-screen resolution of files created in a square-pixel environment, use 648 x 486 (NTSC), 648 x 480 (NTSC DV) or768 x 576 (PAL). To create a single resolution for both NTSC and PAL, use 720 x 540. Maintain, non-square (Crop/Pad for DV scan line difference): Use this option to compensate for the six missing scan lines in NTSC DV. If you have selected a 486-line resolution and are importing a 720x480 graphic or animation, the frame is padded out by six lines, preserving any field ordering in the animation/movie being imported. If, on the other hand, you have selected the DV25 resolution and are importing a full-frame 720x486 graphic or movie, the top four and bottom two scan lines are cropped out of the image. Maintain, square (Do not resize smaller images): Select this option to import graphic files that have a smaller size than the full-raster SD or HD frame. This is typically used for either temporary web graphics (in either SD or HD) or to bring SD-formatted graphics into an HD project without blowing them up and losing quality. Maintain and Resize, square (Resize image to fit format raster): Use this option to resize both smaller and larger images to fit the full-raster SD or HD frame. (It does so while maintaining the file s aspect ratio.) 16

17 Import Settings: Image Tab Changes Option File Field Order (Field Ordering in File) Color Levels (File Pixel to Video Mapping) Description Allows you to select the field ordering (sometimes referred to as field dominance) of the media you are importing. For p, 24p, or 25p projects, these options do not appear; all fields are automatically exported as progressive (still) frames. When the field ordering (or spatial field position) of the imported media matches the field ordering of the project format, no special processing is required. For more information, see Field Ordering in Graphic Imports and Exports on page 499. This setting does not apply to OMFI imports when the import resolution matches the OMFI file. The following options are available: Non-interlaced (Properly ordered for current format): Use this option when the file to be imported has been correctly field ordered for the video format being used (ex: Even or lower ordered for NTSC, Odd or upper ordered for 1080i HD). This is the default option. Odd (Upper Field First) Odd (Upper Field First) ordered: Choose this option if the file was odd ordered and you are importing it into an even ordered format. For example, importing PAL DV into PAL. Even (Lower Field First) Even (Lower Field First) ordered: Choose this option when importing a file with even ordering into a video format with odd ordering. For example, importing NTSC into 1080i HD. Controls how color is handled in the imported images. The following options are available: RGB (Computer RGB (0 255)): Select this option if the imported graphics file uses RGB graphics levels. Most computer-generated graphics use RGB graphics levels. The RGB color values are remapped to ITU-R 601 (formerly CCIR 601) or ITU-R 709 video color values appropriate for the Avid system. RGB, dithered (Computer RGB, dither image colors): Select this option if the imported graphics file uses complex color effects, such as a gradation, and you are importing at a high resolution (2:1). Do not use this option to reimport an image that has already been imported with dithering. 601/709 (601 SD or 709 HD (16 235)): Select this option if the imported graphics file uses video levels based on the ITU-R 601 (formerly CCIR 601) or ITU-R 709 (HD) standard. These graphics include Avid color bars or images that include superblack (zero black) for keying purposes. 17

18 Option Alpha (Alpha Channel) Single Frame Import (Frame Import Duration) Duration n seconds Description Controls how the alpha channel is handled in imported images. The following options are available: Use Existing (Do not invert (black = opaque)): Select this option to import the image, using the existing alpha channel information. Invert Existing (Invert on import (white = opaque)): Select this option to reverse the black and white elements of the alpha channel if they differ from the matte key requirements of your Avid editing application: a white background, a black foreground, and a gray transparency blend between the two. Ignore (Do not use): Select this option to import an image that contains alpha channel transparency information as one opaque graphic. The imported graphic appears as a single master clip in the bin. n If an image contains an embedded alpha channel but your Avid editing application does not support alpha channel import for the file type, select this option to import the image successfully. For information on alpha channel support, see Import Specifications for Supported Graphics File Formats on page 484. Select this option to specify the duration of the single frame created from the import. The default is 10 seconds. This option does not apply to importing sequential image files because each file represents one frame of the clip; therefore, the total number of files determines the total duration. Importing an image with alpha channel creates a matte key effect as a single frame, with no associated media file. Importing as a single frame takes less time and requires less storage than importing as a media file. However, a single frame has limited real-time playback capabilities, particularly at high resolutions. This occurs because your Avid editing application loads the frame into memory and handles it in real time, rather than playing it back from a disk. Autodetect Sequential Files (Autodetect Sequentially Numbered Files) Select this option if you are importing sequential files and you want your Avid editing application to recognize that a sequence of connected files is present and to automatically import the whole sequence. When this option is deselected, your Avid editing application does not automatically import a whole sequence of files that have sequential extensions. You can then select any single file for import. You can import sequential files for any of the supported still-image formats. For information on preparing a sequence of image files, see Specifications for Animation Files on page

19 Fixed in Avid Media Composer v3.0.5 Fixed in Avid Media Composer v3.0.5 The following have been fixed in this release. When performing an XDCAM Proxy to High Resolution Batch Import workflow using different Avid editing systems, you had to make sure the Avid editing applications were installed on the same type of platforms. For example, both on Macintosh platforms or both on Microsoft platforms. The XDCAM Proxy to High Resolution Batch Import workflow did not support cross platform compatible. This has been fixed. Previously, you might have received a SpringBuffer Timeout error when combining effects such as Animatte, Illusion with 3D warp or PIP effects. This has been fixed. Previously, keyboard mapping of audio and video tracks to Shift keys did not work properly. This has been fixed. The duration of group clips did not display in the bin. This has been fixed. Previously, you could not duplicate the Sound TC column. This has been fixed. Previously, the Marquee Title Tool might freeze when creating graphics or saving to a bin. This has been fixed. (Windows XP) Previously, Adrenaline and Mojo might not play with supported PCI-e 1394 cards. This has been fixed. Previously, the Safe Title grid size did not update correctly between 16x9 and 4x3 in a PAL 25i project. This has been fixed. Previously, when the Capture tool was set to IMX30 (MEG30) the Mojo SDI might have recorded the format as DV25. This no longer occurs. You might have experienced errors messages indicating RTTI data errors when you tried to open a sequence created in version or earlier in a system running version 2.8.x or later. This has been fixed. Previously, EDL Manager, FilmScribe, and MediaLog menus did not display in Japanese. This has been fixed. You might have received a DIG_TOO_SHORT error when performing a batch capture in a 720p project. This has been fixed. 19

20 Previously, when playing SD video at 8x normal speed, video might have stuttered. This has been fixed. Previously, you could not apply a Timewarp effect over a Color Corrected clip if the clip was on track V2 or higher. This has been fixed. Previously, the Safe Color limiter did not properly limit signals for HD material if the RGB Gamut limiter was enabled without the Composite limiter being enabled. This has been fixed. Previously, Color Correction was not possible on a grouped Multicam clip. This has been fixed. Previously, if you renamed a folder that contains an open bin in the project window, you might receive a...system cannot find the path specified error when trying to save the bin. This has been fixed. With editing applications connected to a Nitris DX, the audio might have been out of sync while playing back in Multicam mode. This has been fixed. Previously, you might not have been able to apply effect templates to a sequence after the sequence was checked out of Avid Interplay. This has been fixed. Previously, the duration of dissolves in an EDL might not have been accurate. This has been fixed. Previously, after installing MediaLog on a Macintosh with a new user and new settings, you would receive a number of error dialog boxes. This has been fixed. Previously, Timewarp effects might have calculated incorrectly when transferred to EDL Manager. This has been fixed. The editing application might have crashed when performing a JKL trim with projects on shared storage. This has been fixed. When the video quality playback option was set to Full Quality 10-bit, playing back a sequence with SpectraMatte effects would be extremely slow. This has been fixed. Previously, the Save All command would perform a save on an unchanged bin. This would unnecessarily slow down the system. Now, only bins that have changed are Saved during a Save All command. 20

21 Changed in Avid Media Composer v3.0.1 When filler was added to the beginning of a sequence and a Timecode Burn-In effect was added to the topmost track, the application might hang if you changed the display from Timecode to Source. This has been fixed. Sending a sequence to playback did not check the sequence into the Sent to Playback folder. This has been fixed. Effect tracking information did not conform correctly when a sequence was checked into Avid Interplay or exported as AAF. This has been fixed. Previously, when trimming two tails, the wrong audio might play. This has been fixed. Previously, you might have received Bus Error in Main Thread errors when in Multicam Mode. This has been fixed. Previously, you might have received an error when trying to render AVC-Intra clips on track V2 or higher. This has been fixed. Previously, you might have seen a green horizontal line in VBI when using real-time, single track effects on SD material. This has been fixed.
