After converting, the output videos (MPEG-2 encoded MPG files) will seamlessly fit Premiere Pro CC, CS6, CS5.5, CS5, CS4, CS3, etc. By running it, there’s no need to set the codec yourself: the Mac program has optimzied presets for Adobe Premiere. The article would show you how to change MP4 to Premiere Pro compatible MPEG-2 on Mac step by step with a professional yet easy-to-use Video Converter for Mac (Yosemite compatible) from Brorsoft Studio. That’s why you will receive the error message “Unsupported format or damaged file.” To fix the problem, the easy workaround is to convert MP4 to a more editing friendly format, such an Adobe Premiere’s MPEG-2. If your MP4 files are not compatible with Adobe Premiere, it’s probably caused by the codecs in the MP4 videos.

So what’s the matter? The reason is that MP4 is a format container with different codecs. But the problem with MP4 is, when you plan to import the MP4 files into Premiere Pro (Premiere Pro CC included), you may be able to do this, but may be unable to. It is officially stated that MP4 is supported by Adobe Premiere Pro.
