ffmepg two pass
So if you wanted to encode using two-pass VBR, the command line would be something like:
################################
#first pass (if needed to check stuff)
#think it can be that "-vcodec mpeg4" for windows
ffmpeg -f image2pipe -i git.ppm -an -pass 1 -vcodec libx264 -vpre fastfirstpass -b 3000000 -threads 0 git.mp4

#you can try "-vpre max" for very high quality "-b <bitrate and time you found in first pass>"
#this one gives good results with -1280x720
ffmpeg -f image2pipe -i git.ppm -vcodec libx264 -vpre hq -threads 0 -mbd rd -flags mv0 -trellis 2 -cmp 2 -subcmp 2 -g 300 -pass 1/2 -b <3000000> git.mp4

# important about ffmpeg and bitrates
overall average bit rate = file size in bytes * bits per byte / duration in seconds
