I have ripped a few episodes of LOST using MakeMKV to my Mac from an original Blu Ray disk that I own. The videos are encoded in H264, with a bit rate of about 20 Mb/s. I then take the MKV file that MakeMKV creates and open it up in MP4Tools. Since the video is already encoded in H264 and is of allowable bit rate, since the AppleTV and the new iPad should support them based on their tech specs, I select pass through. Because the audio is DTS, I convert that to AC3 5.1 with a 2 channel track. For the device, I select AppleTV (so the new file it creates has a m4v extension). Obviously these are large files, and I am okay with that. I will be streaming these to the AppleTV and iPad using Home Sharing. I don't want to convert the videos because I want the original uncompressed blu ray files, and I tried one episode and it took 9 hours. I have lots of free space on a few external hard disks so I would rather just leave them as they are. The videos playback at a smooth framerate but there are color flashes at random points every second or two. Here is a screen shot I took with the iPad that shows the problem: It does the same thing for the AppleTV. I have tested out the video in VLC and it plays perfectly, so the video file is not the problem. The video plays smoothly and sounds great, but it's just those color flashes that are the problem. Any help would be greatly appreciated!
