Same as December 2013. Good month.
Videos without audio? For After Effects category this is impossible! Probably your search engine was capturing Stock footage section too, where audio is not so important(in ~90% cases)...
There is no any Preview button on Videohive… Why?
7D files are .mov H264 ~50mbp\s
Cut it in Premiere or After Effects and encode with same parameters. You wont loose any details then. I did like that many times with my 7D footages.
Separate Alpha. And render both files with H264
Really? You made that? I don’t believe it… I know you can do better than that…
I mean it’s nice, but it’s not your quality level
