h.264 and adobe premier

I have been trying and looking all over the internet for awhile and seems I can't find an answer. I got the Evangelion 2.22 movie which is a h.264 file 1080p and I wanted to make a amv with it but, doesn't seem adobe premier will take it and not sure why, I have the codecs to watch it and all.

I know it may stupid (cause it might take hours...) to convert, so I saw some little tip that might save you a lot of trouble. If you rename the file so it has a .mov... it might work. I cant guarantee it will work, but you aren't risking anything by trying.

You sure it isn't an .mkv file?

lol thats the funny part i demuxed it out of a mkv file

well this is rather embarrassing i was able to fix my own problem i guess h.264/avc is not able to be used on its own so i had to mux it in to a mp4 container and now it works
