So I found some wonderful 720p HD clips of Crisis Core, thankfully finally without obnoxiously large subtitles destroying the video. I used my newly updated YT Downloader, and with the update came the change that it now takes the HD videos off in mp4's which Sony Vegas dislikes greatly.
It wont let me open them, so I need a program that lets me convert MP4's into something else, like .avi, without losing any of the epic quality I have been searching for.
Please help! Ive looked on the internet but I dont know the first thing about converters....it needs to be free, and it needs to be good. PLEASE HELP ME!!!!
