1 Section 3 Capturing Material Duration: 60 minutes Capturing material is the process of creating media files from video or audio source material. This section describes how to capture material from different sources, such as videotape and file. The following topics provide information about capturing material: Capturing Source Material Configuring the External Device Capturing from Tape Capturing from File

2 Section 3 Capturing Material Capturing Source Material The Avid Explorer Source material is the original, unaltered material from videotapes or digital recordings. This source material comes from a variety of sources, such as video, audio, animated sequences, graphics, and still images. When you capture material with Avid DS Nitris, you are digitally transferring audio or video material from an external device to a storage disk on your workstation. During capture, Avid DS Nitris creates media files (in the form of master clips) based on parameters you set, such as in-points, out-points, and compression. Master clips contain information about the location of the media on your storage disk, the source data s tape name, and the original in and out timecodes. With this information, you can recapture the material at any time. Master clips also include information about the video format, resolution, compression, audio format, and so on. n The Avid Explorer displays the hierarchical structure of files, folders, and drives on your workstation. When you select a project folder in the Avid Explorer, it displays the related project files (clips, sequences, effects) in a window. This window is similar to the bin view in other Avid products like Media Composer and Film Composer. Media Composer: In Avid DS Nitris, any folder that you open in the Avid Explorer can function as a bin. There is no equivalent to the Project Window. From the Avid Explorer, you can capture clips, as well as organize sequences, clips and effects within your project. To access a bin: 1. Use the view switcher to switch to the Avid Explorer if you are in a different view. 2. In the Project panel, double-click your project folder named My First Project. The contents of the folder are displayed on the right in a bin. 36

3 Capturing Source Material Avid Explorer tools let you control the content and arrangement of the folders and windows, and perform tasks. Windows display the contents of folders. You can display multiple windows. When a project is selected, this window is known as a bin. It displays master clips, sequences, and other project files. Panels display the contents of your system in a tree structure. Each panel can display one of three views: My System, Project, or Shortcuts. View modes include large icons, list, details, thumbnail, and script views. View switcher lets you access different toolsets or views within a particular layout. Folders usually contain source clips and other objects for use in your sequence. At the moment, the folders are empty because nothing has been captured. The Avid Explorer tools let you navigate through and manage the contents of folders. The tools at the top of the Avid Explorer let you navigate to different folders and change the display of information in a window. 37

4 Section 3 Capturing Material Avid Explorer tools at the top of the view. Show/Hide Panel 1 Cascade Capture Settings Show/Hide Panel 2 Tile Path Help Organizing your Project Files For more information about the Avid Explorer, click the Help button. Before capturing any material, you will create additional folders in your project folder to hold master clips. You may want to create separate folders for your video clips, audio clips, still images, and even one for custom presets. By organizing your project using a system of folders, you can locate files quickly and easily. To create a folder: 1. In the bin that is displayed in the Avid Explorer, right-click an empty area of the bin and select New > Folder. A new folder is created in the bin. 2. Type in a new name and press Enter. We created a folder called Master Clips for storing the master clips! 3. Continue adding as many folders as you need. You can create additional folders inside the new folders. Although it s not necessary right now, here s how you can delete any extra folders that are not needed. To delete a folder: t Right-click a folder and select Delete. 38

5 Capturing Source Material Changing the View Mode In a window, there are several views to help you locate clips for a sequence. The tools at the bottom of the window let you change the way the contents of the window are displayed. Go ahead and click any of the icons to see the various views. Large Icons view displays clips as large icons. List view displays clips as a list without details. Details view displays clips as a list with details. Script view displays both pictorial icons and clip information. List lets you select a customized view. Thumbnail view displays clips with pictorial icons. Identifying File Types in a Bin For more information, see Working with Bins in the Help. Avid DS Nitris media files have their own icons, which appear on or beside clips in a bin. When an icon is highlighted in red, it means that Avid DS Nitris could not find any media associated with a clip. This clip must be recaptured before you can work with it. Icon File type Icon File type Audio clip Video clip Background or composite container clip Sequence Combined audio and video clip Still image Audio container clip Linked still image 39

Select the View tab. Deselect this option. 4. Deselect the Hide extensions for known file types option and click OK. 40

7 Configuring the External Device Configuring the External Device n You ll probably capture material from videotape or audiotape most of time. First, you ll need to configure the device from which you will be capturing. To specify the settings for an external device, such as a videotape recorder (VTR) or deck, you ll be using the Deck Configuration view. Media Composer: The Deck Configuration view combines the Deck Configuration and Deck Preference settings. Avid DS Nitris includes templates for many different types of devices. You can use the settings in the templates, or adjust them to suit your own requirements. n You can also save the settings for your device as a preset, so that you don t have to reconfigure the device each time you use it for capture or output. A preset is a customized set of properties that you save for reuse later on or for other projects. For the following procedure, you will need access to videotape material and a deck. 41

8 Section 3 Capturing Material To configure your tape deck: 1 Open the Deck Configuration view by selecting View > Multi-Instance Views > Deck Configuration. 2 Click the Fast Menu button and select Add New Deck Preset. Give the new preset a name. 3 Select the Thumbnails view. 4 Double-click the preset you created. A green checkmark indicates that it s active. 6 Click the Help button for details on each parameter. 7 5 Set the options 8 for your device. Click the Check Machine button. Click the Save button to save your deck preset. 9 Close the Deck Configuration view. For more information, see Configuring the External Device in the Help. 42

9 Capturing from Tape Capturing from Tape Although there are several ways to capture from tape, you ll be using the Capture Tool to log and capture clips, so that you can later recapture using frame-accurate timecode. To log and capture clips: 1 Open the Capture view by selecting View > Single-Instance Views > Capture Tool. 2 Click the Tape button. 3 Set the Log/Capture button to Capture Select your deck preset and click the Check button. Select a tape or name a new one. Click the Target button and select a folder to hold the captured clips. If you created a folder for master clips, set this as the target folder Enter number of extra frames to record before the in-point and after the out-point. Select the channels you want to capture. Enter a base clip name to prefix all captured clips. 10 Click the Capture Settings button. The capture settings are displayed. Set the options that are relevant to your system.

11 Capturing from File Capturing from File Avid DS Nitris lets you capture various file formats. Besides video, you can capture still and animated graphics files, and audio files. To capture from file, you will be using the Avid Explorer in Avid DS Nitris. Logging and capturing from file is like capturing material from tape. That is, you can log the material without capturing, or log and capture at the same time. Logging creates information about the source material and in/out timecodes in a clip, so that you can perform a batch capture later on. Before you capture the files, you ll need to specify the capture settings. 45

12 Section 3 Capturing Material To log and capture from file: 1 At the top of the Avid Explorer, click the Capture Settings button. Media Composer: The Capture Settings view is similar to Import Options. There is no Import or Batch Import dialog box. 3 Click the Help button for more information on each parameter. 2 Set the video quality at which you want to capture material. You can choose a lower resolution, or use compression to save space on your storage device while you do a rough cut. 4 Select the storage folder for the media. 5 Keep the default setting for the audio quality. 6 Select the storage folder for the audio media. 7 Click the browse button (it has three dots) to select a folder to hold the master clips. We selected the Master Clips folder we created earlier. 8 Keep the default conversion settings. 9 Keep the default settings for the source files. 10 Close the Capture Settings view. 46
