Do you know the difference in performance with MPEG4 and H.264 ?

 

The H.264, also known as MPEG-4 AVC (Advanced Video Coding), is a video compression

standard that offers significantly greater compression than its predecessor.

The H.264 standard is expected to offer up to twice the compression of the current MPEG-4 ASP

(Advanced Simple Profile), in addition to improvements in perceptual quality.

The H.264 standard can provide DVD-quality video, and is considered promising for full-motion

video over network connection.

 

As you can see below MPEG4-2 is the original MPEG-4 ASP format and it was enhanced and improved and now we have  H.264 (MPEG4-10) which you can see is substantially clearer and also smaller in data size.

 

What is all this jargon being used...CIF, QCIF, D1, 4CIF...??   Below is a comparison of the size of QCIF, CIF, 4CIF, D1...

For the purist D1 is slightly higher resolution than 4CIF but its marginal.
