Got some YUV420 1920x1080 60FPS videos i want to encode with MPEG2 with different quality levels. According to stackoverflow: ffmpeg conversion to mpeg2video I could do it with

ffmpeg -i input -codec:v mpeg2video -qscale:v 10 output.mpg

The qscale parameter has a linear scale 2-31 and 31 is the lowest quality but it's not as bad as I would expect the lowest quality MPEG2 video to look like.

Also tried these:

-vcodec mpeg2video -maxrate 4000k
-vcodec mpeg2video -qmin 69 -qmax 69

maxrate gets ignored and i get the message that it is too low and qmin 69 quality is still higher than i want it to be.

Does anyone know how to achieve a really low quality MPEG2 video with ffmpeg or any other MPEG2 codec i could use to do this? Thanks

  • Providing samples might be useful for receiving help on this kind of question. Also you might ask this question on ffmpeg's irc channel (They're very helpful). – tyb Feb 19 '17 at 00:16
