I'm importing and playing some mp4 AVC files into premiere. I believe they are 1080 interlaced, 60 fps. The project is 30 fps.
Premiere indicates that the file has a framerate of approx. 15, and when playing back video is half speed and audio is normal speed (so there is only audio in the first half of the playback).
I tried using the Interpret function to double the framerate to 30, but that just made the sound high-pitched (and still only audio in the first half of the clip).
How do I force premiere to interpret my mp4 files correctly?
i was having the same problem, so i kept increasing the frame rate but it kept getting slower. what tried next help a great deal,instead of increasing the frame rate try lower it to the lowest it can go. For me it was to 4 frame rate not 15 or 30 that can be too high. Hope it helps
It's possible Premiere doesn't work with all .mp4 files, just as it doesn't work with all MPEG-2 files. Premiere's compatibility for these format are centered around the camera standards of AVCHD and HDV respectively. Other types of MPEG-4 or 2 files may or may not work. For example, Divx is a flavor of MPEG-4 which many, many people have issues with.
My own recommendation is to use a consumer program in cases where the files did not come from a pro camera, as such programs are often more forgiving with non-camera formats than is Premiere. Movie Edit Pro from Magix I hear works pretty well with these things.
