Are you saying you output an MP4 and you couldn't get it play?

Which media player are you trying to play your video with? I hope it's not Windows Media Player.

Give the great free VLC Media Player a try.

If you're successfully outputting over 2000 different versions of your video and none of them will play, it's not likely an issue with Vegas.

VLC should work just fine, depending somewhat on (un)compressed and disk speed. I play MP4's of 4k material from a single HDD with no problem in VLC.

(2160 templates is 2160p templates is not 2160 attempts. Context, man, context.)
