Obviously the answer is Blu-Ray, as the x264 in the MKV are taken from Blu-Ray as a source.
The thing I want to know is how much of a difference is there? same as a retail DVD rip to a 1400mb xvid file for instance?
Anyone done any direct comparisons? I ask as I haven't seen Blu-Ray but have seen a lot of mkv's and i'm very impressed with them.
edit - I posted in this forum as mkv are only playable currently on computers afaik.
Válasz:
Depends on the bitrate and resolution, largely. Obviously some stuff compresses significantly better than others too.
If you take a typical 9GB mkv with a 2hr film, you're looking at 9.5mbit average bitrate for the video. That's more than a little tight, and a 1080p encode at that bitrate will certainly suffer with most content. That's why many are scaled down to 720p, for which 9.5mbit is way more than plenty. In fact, with that 9GB, you could easily do 3 hours at 720p without losing any significant quality.
For that same 2hr film, if you used 13.5GB then you have 14.5mbit video to work with, and that's definitely enough for 1080p with almost anything. Indeed, some of the very best HDDVD encodes like the Matrix2 used 15.5mbit average for the video (and even some quality Blurays like PotC2 are only 17mbit or so, and they have no limits).
