Hi Julian, all frames have different sizes depending on the content’s complexity and groups of pictures have different sizes mostly depending on how quickly the image changes. That’s why the bitrate varies over time and every part (split) of the video has a different bitrate. The overall bitrate is an average of all individual bitrates (weighted by duration of the splits).
You can limit the file size of one part with the -fs option, but you know only afterwards how long it got. And then you can use this duration to start the next part from this point in time.
