Frequently Asked Questions

1. What is H264?
   H264 is the next-generation video compression technology in the MPEG-4 standard, also known as MPEG-4 Part 10. H264 can match the best possible MPEG-2 quality at up to half the data rate. H264 also delivers excellent video quality across the entire bandwidth spectrum — from 3G to HD and everything in between (from 40 Kbps to upwards of 10 Mbps).
   
   
2. Does H.264 require special hardware?
   While H.264 is a computationally advanced codec, it runs on today’s shipping computers with no additional hardware required. For example, a full HD movie (1920x1080, 8 Mbps, 24 fps) encoded with H.264 plays back beautifully on a dual Power Mac G5. Internet-sized content (40kbps - 300kbps) will run on the most basic of processors, like those in mobile phones and consumer-level computers.
   
   
3. How does H.264 compare with MPEG-4?
   The MPEG-4 video, referred to as MPEG-4 Part 2, plays an important role in the evolution of standards for the Internet and wireless multimedia industries, where it has been widely adopted. H.264, also known as MPEG-4 Part 10, is a newer technology than MPEG-4 Part 2, providing up to four times the frame size of video encoded with the MPEG-4 Part 2 video codec at a given data rate. H.264 will undoubtedly build upon the success of MPEG-4 Part 2.
