H.264 or MPEG-4 Part 10, Advanced Video Coding (MPEG-4 AVC) is currently one of the most commonly used formats for the recording, compression, and distribution of video content. But the problem with H.264, many folks found it's a painful experience to edit edit H.264 file with Final Cut Pro on Mac. In fact, H.264 is an aquistion (camera) and distribution (web streaming) codec. It's highly compressed, which means that the files are small, and Final Cut has to do extra work each time you play your timeline, make an edit, etc. Apple ProRes 422 is an editing codec. It uses much less compression, which means that the files are big, but Final Cut can play it more easily. Thus, when you get many H.264 encoded videos and want to edit them with Final Cut Pro, iMovie, or Adobe Premiere, it's better to take advantage of the ProRes codec.


Editor's Note: Best practice is to edit in ProRes 422, especially if you have lots of layers and effects. That means you spend a little extra time optimizing your files to ProRes 422 before you start, but you save time in the long run.

As you got into more complicated editing such as adding multiple clips and transitions and effects you would start to see a more pronounced difference, i.e. FCP would need to render more often and editing wouldn't be a smooth. H.264 is really optimized to be a delivery codec while ProRes is optimized to be an editing codec. That said, if you just need to do a simple edit and your Mac has the power to edit H.264 you can get away with it no problem, but if you plan to do a heavy edit with lots of transitions and effects and color grading you will be best served by ProRes.
