Converting a 23.976p NTSC Sequence to 720p/23.976
Because the source edit rates are different for these formats, you cannot simply change the
project and sequence format. The following sequence is based on source material shot or
transferred to 720p/23.976 and edited offline in a 23.976p NTSC project.
To convert a 23.976p NTSC sequence to 720p/23.976:
1. In the 23.976p NTSC project, duplicate the final sequence and move it to a new bin.
2. Decompose the sequence.
3. Select the master clips and export them as a shot log file.
4. Create a 720p/23.976p HD project.
5. Import the shot log file into a bin.
6. Batch capture the clips.
7. Open the SD bin containing the duplicated sequence.
8. Relink the SD sequence to the new HD clips.
See “Relinking Media Files” on page 467.
Editing at 60 fps
The project type 720p/59.94 uses a screen resolution of 1280 x 720 at a frame rate of 60 frames
per second. Editing at 60 fps is similar to editing at 24 fps because both resolutions are
progressive — they use full frames instead of interlaced fields. Note the following:
• Single-frame step commands move at 1/60th of a second. Single-field step commands are
deactivated; if you click a button, your Avid editing application beeps.
• Draft Quality plays back at 30 fps. Full Quality plays back at 60 fps.
• You can mark IN and OUT points at 1/60th of a second increments.
• You can trim at 1/60th of a second increments.
• Transition effects default to one-second duration (60 frames).
• Deck control for capture and digital cut is limited to 30 fps. A message box warns you if you
try to mark an odd timecode value (such as 01:00:00:03).
n
1080i/50 and 1080i/59.94 are interlaced resolutions that you edit at 25 frames per second and
30 frames per second.
