I am liking it so far.
I REALLY like the option to not delete files in mass uploader, due to very slow broadband in area (5 / 1 MBs dsl, only provider in town) I often have to ftp large files up overnight and I use the massuploader folder.
ability to keep or delete files is a good thing to have in case of some conversion fail.
I like the keep mp4 as is option too, would like to see a second related option that ONLY processes to vreate thumbnails. imagemagik or ffmpeg can do this fast w/o needing to fully transcode the video.
