If you are not aiming for a specific file size but rather constant quality of your encodes, use "-crf" (constant quality) instead of "-b" (bitrate) to save some time.
Cool, that was another question I had in the back of my head...
So -crf is made to replace -b, and not only complement it ? That's what I had figured, but I couldn't make sure...

If I use -crf, is it a good idea (or even necessary) to use -minrate/-maxrate in order to achieve fairly constant quality ?

And what value of -crf would you personnally recommend for 1920x1080 videos ?

Thanks so much !
