Got a bit of a problem.. I rendered a quicktime using the animation codec out of a 3d program on a Mac( Lightwave 3d) And after a long render, I went to play the quicktime and it plays back like there is only 4 frames.. (210 frame were rendered out) when I look at the item properties on the file I see it says it the right lenght, but it rate is 3000 frames per second... I can scrub through and see all the frames are there .. just cannot get it to play back correctly.. So is there a way to change it to 29.97 frames per second ??
Check it in the QuickTime Player- make sure all frames were actually rendered. I typically render 3D to image sequences rather than movie files just in case something like this happens you can render a frame at a time to replace the lost frames rather than have to do the whole thing over every time.
