Interface icons have also been redesigned to look better on retina displays. The main window of the app has been redesigned to improve usability, the goal of the developers was to make it easy for users to go through the steps necessary to configure a transcoding queue, reading the window from top to bottom, left to right. Version 1.1.0, released on Sunday, includes many bug fixes, improvements and new features. From my experience, it’s always been the most performant video converter for Mac, using all CPU cores to get the job done as quickly as possible while exercising your Mac’s fans. Handbrake is a Mac utility that can convert video files to several different codecs, it can even rip DVDs and Blu-ray discs. If you are extremely concerned about quality it would make a lot more sense to just stick with the highest available 2160p version without any re-encoding.After releasing its 1.0 almost two years ago and going through security issues in 2017, Handbrake, a video transcoding app, is finally getting a new update. It takes over twice as long and the result is not noticeable. I certainly would not waste time on downscaling a UHD movie if the purpose was to make a smaller file size. The 2160p ➜ 1080p conversion took 2.7 times as long as the 1080p ➜ 1080p conversion. This is normal since every conversion is calculated a little differently. The file sizes for both output files were similar as expected. Downscaled 2160p ➜ 1080p version to the right. Here is a lossless side-by-side export from KARMA: 1080p ➜ 1080p to the left. I still could not see any difference when going frame by frame. This is important because one is more likely to spot quality loss on a larger 4K monitor than a low-resolution monitor. I even zoomed in at 200% to make sure that the resolution of my 3440p monitor was not giving me a false impression. In my opinion, both videos were visually identical even to the most meticulous eyes. None of the videos gave a better result than the other. What I was looking for was the difference in detail and quality loss. Of course, the artifacts were not in the exact same place on both videos, but this was expected because each conversion is going to be different. This was expected since the UHD version has to be converted to a different colorspace. I compared both output videos in KARMA and could not see any difference at all except for a slight variation in color and placement of the compression artifacts. Constrained CRF at 16M buffer size and 8M max rate.Here are the settings I used in Handbrake. I converted both videos with the exact same H.264 settings in Handbrake.Used TMPGEnc MPEG Smart Renderer 6 to cut those same portions from each video.I inspected both Blu-rays videos in BitrateViewer to find the highest bitrates in the video.I experimented with this in Handbrake to see if I was able to get any better results using the 2160p as the input file. The only two noticeable effects you will get are a considerably longer conversion time, and slightly different colors if the 4K version is UHD and you are converting it to SDR. You are not likely to notice any difference at all if you convert both videos with the same encoding settings. Let’s say you want to make a reduced file size version for your iPad or your Plex server, but you still want it in 1080p with good video quality.ĭoes it even matter if you select the higher resolution video as the input file? From a logical perspective, the 4K version should give a better result, right? The short answer One in 1080p HD and the other in UHD 2160p. Say you have two Blu-ray versions of the same movie.
