As a note, I just had to get this off my chest, and I'll only say this once. Some of FFmpeg's command line syntax is *confusing* and *super confusing* for beginners. For instance this: ffmpeg -r 30 -i input_file specifies a framerate *override* for the input, however if you specify it for the output, its just the "normal" output frame rate...:
what else would you expect?
ffmpeg -i input -r 10 output and this: ffmpeg -i input -f rawvideo -f nut output.nut Using (or being able to use) "-f" typically using two "-f" s would be an override. But in this case it isn't. In fact, its using "-f" to specify two entirely different aspects of the output file. It's hard to see, but to beginners, this is *super* confusing.
it *is* a override
Being able to specify global settings "in the middle of an input file" is also confusing..
there is NOTHING "in the middle"since it's *after* "-i" it's no longer for the input file and when you specify something twice the right one wins, the same for GCC because otherwise you would not be able to override at all
