make video conversion more efficient #49
Description
right now, converting anything to mp4 is done using the ultrafast preset in ffmpeg, this is fine for now because speed of video conversion should take precedence over storage efficiency/compression
but after the conversion is done and the video is available, if the cpu isnt being used by anything, AND the source video is still available, it should start redoing the video conversion with the veryslow preset, and so whenever the new video is available, just replace the previously generated inefficent video
overtime this will help cut down on disk usage
