As said, this command is missing a video bitrate.

You forgot to set the video bitrate.

Hi guys,
I'm encoding videos target a max average bitrate and want to achieve good
encoding quality.
When I use
ffmpeg.exe -i a.mp4 -c:v mpeg4 -profile:v 15 -vtag DIVX -bufsize 308
-maxrate 800 -bt 800 -an a.avi (so that maxbitrate will be
8000kbps), in this case I get a.avi wit
