However, while using any other player or video editor the playback was discrete and laggy. The audio was obviously ahead of video. My PC is good enough – remember that it plays your files smoothly with Canon EOS Movie Utility.
I performed some testing with several PCs trying to play 4K .mov files shot by Canon EOS 5D Mark IV and gathered the following statistics:
The Canon EOS Movie Utility cannot do anything with the video files, it’s capable only of playing and splitting them. But it can neither edit video, nor produce video files.
I performed further testing and found out that:
1. TVs would not play.mov files shot by Canon EOS 5D Mark IV from USB flash. I tried Sony and Panasonic. Keeping in mind that according to page 420 of the User Guide even if I connect the camera to the TV using HDMI cable I will only see full HD video, I wonder if 4K .mov files shot by Canon EOS 5D Mark IV can be played on TV at all.
2. Page 421 of the User Guide says that I can transfer video files to my PC to view and edit them using standard programs. I reported above the result with video players. The result with video editors is even worse. I tried Adobe Premiere CC 2017, Cyberlink PowerDirector 15, Vegas Pro 14.
None of them supported 4K .mov files shot by Canon EOS 5D Mark IV.
The bottom line is that I failed to find a method to properly playback 4K .mov files shot by Canon EOS 5D Mark IV on TV and on PC and edit them on PC.
Of course, I tried to resolve the above issues with Canon support. The answer was surprising: they just said that they just tested their .mkv files with Canon EOS Movie Utility and do not care about anything else.
I wonder if anybody had better experience with 4K .mov files shot by Canon EOS 5D Mark IV and can educate me on how to handle them.

I don't know much about 4K video but my understanding is that the 5D Mark IV uses Mjpeg codec which is very inefficient compared to H.264 and H.265
Most people use some sort of video converters to convert native Canon files to H.264 or 265 mpg files before playing on the PCs.
