REMUX Bitrates Vary On Different Rips Of The Same Movie?
Posted: Wed Dec 06, 2023 10:41 pm
I've been going down the rabbit hole trying to understand bitrates in UHD REMUXES and I can't seem to find any clear info on why there are so many different bitrates for the same REMUX'd movie when looking at MediaInfo. I looked at 3 different rips of the same movie and all three had different bitrates. How is this possible if REMUXEs are just direct rips of the UHD Bluray? One example is John Wick Chapter 3 Parabellum. According to Blu-Ray.com the official disc's bitrate for this movie is 63.15 Mb/s. The top one posted below shows 70.8 Mb/s, the second one matches what Blu-Ray.com lists at 63.2 Mb/s and the third rip shows 82.5 Mb/s. What's going on here? Are the other two just inflating bitrates with no benefit to the picture quality?
