ffmpeg/mpeg4 is Ok in general, probably your video bitrate was too low 
resp. the image dimension too high for the chosen bitrate. Important for
quality is the relation between bitrate and image dimension, which is 
called BPP - Bits Per Pixel.

You find some information about this in the documentation:

It's there:

If you use filters you can use the preview window to check your 
settings. But note this preview doesn't cover the video encoding, so you
can't use it to rate video codec quality:
