working on a project at the moment (it is a short action film, done in all-one-shot)
for some of the action sequences i am compositing effects into them. i cut the section of video file i want to edit and open in after effects
but when i attempt a 3d camera track, the camera tracker either doesnt initialize, or it seems to do its job but gives me no tracking info, or it fails.
now, when i take the same piece of footage and export it from after effects, and re-import it , the camera tracker works quite efficiently.
any ideas whats going on?
It's probably failing due to the codec of the footage involved. A better workflow would be to cut the piece you want to track in Premiere and export it via Premiere or the Adobe Media Encoder into a production codec (something like Cineform or QuickTime with the PNG codec and NOT something like an MP4/H.264) and run the camera tracker on the new codec.
