'--end-usage' has four options: vbr, cbr, cq, q
When you enable '--end-usage=q', the '--cq-level=' parameter works just like '--crf='

That's not what the page says. It's clear about setting bitrate to 0. And that file is smaller despite being perceptually the same. You say the parameters are different, and that's obvious, given the file size, but that's not the point. The point is the ffmpeg files are smaller, and perceptually the same. And they might even encode faster on ffmpeg.
