I have a question regarding the proper buffer size for video made with ffmpeg applications. For example, when I use the Videora Apple TV converter, it specifies a default buffer size of 10,000 - which I assume to be 10 kilobits. But I am unsure how to change this for different video settings, or even if it should be changed. For example, if I want to make a 640 x 480 video at 1024 kbps, and a 1280 x 720 video at 3072 kbps, what would be the best buffer size for the two different bit rates? I am assuming that there should be a difference between the two. But I can find almost nothing online explaining this option in any detail.
