When do I use the MPEG-4 or H.264 codecs on the Video tab?
The MPEG-4 and H.264 codec options on the Video tab should only be used if you are planning to create a QuickTime movie containing video compressed in this format. In this case, you would choose either of these codecs on the Video tab and use QuickTime as the Output Format on the Output tab. The resulting file will have the extension MOV, as it will be a QuickTime movie, and the frame size will be the full frame size of the DVD. Should you want to create movies with the smallest possible size in true MPEG-4 file format (extension MP4) or iPod movie file format (extension M4V), you should instead follow the instructions we describe above. These files will have a reduced frame size over the original DVD. The reason is that Cinematize follows a process of extracting to intermediate files followed by combining those files together into the final format. We do this to get the best possible compression for the final file. When working with true MPEG-4 and iPod movie files, you want to allow
