HD Workflow: Video-Based Television
1509
To create a video-based HDTV program:
1. Use an HD VTR to downconvert the source tape to 30i NTSC, 25i PAL, or 25p PAL.
2. Open a project that is suitable for HD finishing.
When you start the online session, you can create a new project in the final format, or use the
original project and change the project format. If your project requires final mastering in
HD, use the corresponding SD project for offline editing. For more information, see “Offline
Formats for HD” on page 1108.
3. Capture your material. Edit, apply effects, and create a final sequence.
Avid HD editing applications support direct device control at 24 fps, enabling you to capture
true 24-fps timecode from HD decks. When you are capturing 23.976-fps or 24-fps material
in HD, the Capture tool displays 24-fps timecode for the Mark IN and Mark OUT points.
After you capture a clip, the Start and End timecodes are also shown as 24-fps timecode.
4. (Option) Export an OMFI or AAF file to a Pro Tools digital audio workstation to create a
final audio mix.
For more information, see “Transferring Audio Files” on page 1128.
5. If you started the project in a different format, change the project format to the
corresponding HD online format — see “Changing the Project Format” on page 1514.
