You're right that lossless encoding can still have different filesizes -
*but* depending on the encoding options [1].

I must admit that I also thought that if I'd use the same FFmpeg build,
with FFV1 and the same encoding arguments, as well as the same video
source, I'd get the same filesize.

Am I overlooking something?
