I have some mp4 footage that plays in sync in Quicktime and when I 'get info' in that programme it says it is at 25 fps. When I link or import it into my 25 fps project in MC the sound is out of sync. When I check the clips in MediaInfo app I get:
So it is identifying this as 25 fps footage but with an orginal frame rate of 29.97. And the listed standard is NTSC. So I created a new MC project at 29.97 and then AMA linked to the footage and it's out of sync. In the FPS column in the Bin it says that the frame rate of these linked clips is 25.03 fps. I think this frame rate might be key because I worked out that the audio sync error was around 19 frames in my 25 fps project and that matches the error caused by a clip at 25.03 fps in a 25 fps project.
