Answers.Text: I'd say that this statement is *technically* wrong, but practically accurate. There is a mathematical equation that will answer the OPs question, but it just the math at the heart of the encoder.

Answers.Text: Yeah, I am familiar with the work of Claude Shannon. But practically, there is no way to find the mathematical "best fps" without trial and error/binary search.

  No, because it's content dependent. Video with high motion contains more information than a nearly still scene does. Hence it takes more bits to encode.
