Also, for free gains (in case you're not already), make sure you're using the 'high' profile. Usually I use something like this (note: I don't know if you want to further compress audio or not, so I'll just have it copy for this example):
ffmpeg -i input_file.mp4 -movflags faststart -c:v libx264 -c:a copy -profile:v high -tune:v animation output_file.mp4
