Frame Rate Issue
on Apr 11, 2013 at 9:25:10 am

I burned a BluRay in DVDA from an H264 project created in Avid Media Composer: the original project was 25fps. The project framerate in DVDA is by default 24fps: I left it like this because I assume that this is the framerate for BluRay. I am experiencing a glitch every second.. should I in fact be setting the DVDA project to 25fps?

The DVD spec allows for three frame rates: 23.976 fps, 25 fps, and 29.97 fps. Blu-ray offers even more choices (29.97, 25, 24, 23.976, 59.94, and 50).

If your source footage was at 25 fps, then you should encode at 25 fps for the best picture quality (really, the best motion quality). Encoding 25 fps at 24 fps forces one or more compromises, which necessarily reduce quality. For example, you can turn on frame blending, but that makes the picture less sharp.

Keep the quality and preserve the frame rate.
