H.264 or MPEG-4 Part 10, Advanced Video Coding (MPEG-4 AVC) is a video coding format that is currently one of the most commonly used formats for the recording, compression, and distribution of video content. But the problem with H.264 is, when you plan to edit the video with H.264 in Sony Vegas Pro (Vegas 13 included), you will encounter problems like these:

"I currently capture my files using the Hauppauge HD PVR, recording in H.264 .mp4 format in 720p, and I use Sony Vegas to render my files. Lately I've had some slight issues with Sony Vegas and actually importing my raw .mp4 file in. I'd usually have some weird issue about "file cannot be opened"..."

"A client gave me an SD card with AVI files on it from his consumer camcorder. I tried to open in Vegas 13 but it either says "can't open" or I just get the "no drop" icon. GSpot identifies it as a H.264/MPEG-4 AVC (in AVI). It says "codecs are installed", so it should work right?"

As you know, MP4, AVI, and MOV are all the supported formats of Sony Vegas Pro. Why Vegas can't import and open H.264 AVI, MOV and MP4 videos correctly? Well, the problem is mainly due to that Sony Vegas Pro is pretty picky with the codecs of what it'll accept; it doesn't like H.264 in MP4, MOV and AVI container. That's why Sony Vegas Pro won't open it. To fix the problem, a good enough solution is to transcode H.264 to Sony Vegas Pro more editing-friendly format like MPEG-2.
