I'm trying to create a video loop to match a piece of audio. Usually I can just change the duration of the video to half the audio length, duplicate and reverse it to loop. For some reason I can't time stretch this video properly. When I choose a duration of 05:59 it changes this to 06:29. I can't even make a new composition of 05:59 without it changing. After trying many work around's I noticed that when I scroll through a composition my preview time readout goes from 05:29 to 06:00. I opened an old project and going frame by frame the time jumps from 05:24 to 06:00. It's even happening in premiere pro, it jumps from 05:29 to 06:00. I've closed and reopened both programs and rebooted. Any ideas?
Sorry for slow response. Had to go out of town for work. The footage is 30fps. Based on a post in the adobe forums I've tried changing it to 29.97, 23.976, and 25 but it still jumps ahead at around the same time.
