You can adjust the other encoding settings (e.g. quality , speed, presets, etc...)

Once you are happy, you can use a ffmpeg GUI to batch convert with a preset e.g. ffqueue or tencoder

or use a dos command to batch convert all the MP4's in a folder e.g.

for %a in ("*.mp4") do ffmpeg -i "%a" -map 0:0 -map 0:1 -map 0:2 -c:v libx264 -s 1280x720 -c:a copy -c:a copy "%~na.720p.mp4"
