Additional Tips - Some more info you may want to know:
About H.264: A standard for video compression; known as MPEG-4 Part 10, or MPEG-4 AVC (for Advanced Video Coding); the latest block-oriented motion-compensation-based codec standard developed by the ITU-T Video Coding Experts Group (VCEG) together with the ISO/IEC Moving Picture Experts Group (MPEG).
About MPEG-4: A collection of methods defining compression of audio and visual (AV) digital data; introduced in late 1998 and designated a standard for a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) under the formal standard ISO/IEC 14496; uses of MPEG-4 include compression of AV data for web (streaming media) and CD distribution, voice (telephone, videophone) and broadcast television applications.
About M4V: MPEG-4 file extension used for videos downloaded from the Apple iTunes store; includes music videos, TV episodes, and full-length movies; similar to an .MP4 file, but may be copy-protected using Apple's FairPlay DRM copyright protection.
About MP4: Movie or video clip that uses MPEG-4 compression, a standard developed by the Moving Picture Experts Group (MPEG); commonly used for sharing video files on the Internet.
About MOV: Common multimedia format often used for saving movies and other video files; uses a proprietary compression algorithm developed by Apple Computer; compatible with both Macintosh and Windows platforms.
About AAC: Compressed audio file similar to a .MP3 file, but offers several performance improvements; examples include a higher coding efficiency for both stationary and transient signals, a simpler filterbank, and better handling of frequencies above 16 kHz; maintains quality nearly indistinguishable from the original audio source.
