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
Capturing Source Material
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.
The Avid Explorer
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®.
n
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.
Capturing Source Material
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.
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.
View modes include large icons, list, details, thumbnail, and script views.
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 switcher lets you access different toolsets or views within
a particular layout.
Avid Explorer tools let you control the content and arrangement of the folders and windows, and perform tasks.
For more information about the Avid Explorer, click the Help button.
Organizing your Project Files
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.

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.
For more information, see “Working with Bins” in the Help.
Identifying File Types in a Bin
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.
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.

You may find it useful to see the extensions of file names.
To see file name extensions on your system:
1. Open Windows Explorer.
2. Select Tools > Folder Options.
3. Select the View tab.
4. Deselect the Hide extensions for known file types option and click OK.
Deselect this option.
Configuring the External Device
Configuring the External Device
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.
n
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.
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.To configure your tape deck:
For more information, see “Configuring the External Device” in the Help.
Open the Deck Configuration view by selecting View > Multi-Instance Views > Deck Configuration.

Click the Fast Menu button and select Add New Deck Preset.
Give the new preset a name.
Set the options for your device.
Click the Save button to save your deck preset.

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.
To log and capture from file:
