I’d recommend a RAM preview, read the help for more information about this. audio off, a lower resolution, or smaller view of interest in a RAM preview helps give you longer playback, not to mention lotta ram.
this is the matrix technique for creating missing frames. They used interpolation software. This technique works for jumpy pans, tilts, dollies, spins, rotations… and of course stop motion. Here’s a more detailed post.
1.Put 29.97i video in new 59.94 “start” comp so that timewarp can access both fields.
2. add effect->time->timewarp speed at 50%, extreme detail on.vector 100 if needed.
3. make new “output” comp 99 fps and drop “start” comp inside it with timestretch 50%
4. output “output” comp with original fps. It will maintain the same fps but will smooth out any jerky movements or missing frames.
