What extension does H264 use? Is it an .avi file or does it have its own extension like .divx?
You may come across all kind of file extensions and still the codec can be H264: – .avi – Yes, people use .avi for H264 videos too! – .mp4 – Nero Recode and Quicktime use this format. Better than AVI as you can store AAC audio as well. – .mkv – Matroska container – can support many video and audio formats. Have a look here for more info. – .h264 – This extension is not commonly used. Maybe in the future.
