VFR produces files with constant frame rate
Posted: Mon Jul 09, 2012 2:38 pm
I encode ota recordings that are broadcast at 59.940 frames. To get my encoded file to play back smoothly I've had to encode it at 29.97 frames and I use Peak Frame Rate so that duplicate frames can be discarded.
I've noticed that if the source was 1080i I end up with a much smaller file and that its framerate is listed as VARIABLE. But, if the source was 720p I end up with a larger file and its framerate is listed as CONSTANT.
Does VFR only work with 1080i sources or am I doing something else wrong?
Thanks in advance.
