For years now I have been converting my blu ray collection to MKV files (using MakeMKV) and then transcoding them to smaller mp4 files (using Handbrake). I use the slow x264 preset as well as a constant quality of RF 18. I usually am able to get a pretty good quality conversion, with very little perceivable quality loss. However, I am upgrading to a 48TB raid to store my collection (28 more than I currently need, leaving me quite a bit of room to expand by collection). I am wondering if I am missing out on quality by not remuxing the files using something like Subler, especially if I have the storage space (I have the power to transcode these movies, so that's not a concern). I tried a comparing a 40gb remuxed blu ray compared to a 20gb compressed handbrake file. They looked very similar, but the Handbrake looked slightly more saturated. I was wondering if anyone has any experiences with remuxing, or has any opinion on the subject (difference between it and transcoding). I seem to be stuck between choosing a slightly smaller quality gain for almost 2x the size. Are there any cases where remuxing would make more sense than transcoding? As a side note, I do stream my collection from iTunes to a third gen Apple TV. I wish it supported HD audio, as I now pass through the hd audio files when transcoding (future proofing them for now).
