What Is 4K Ultra HD Blu-ray?

There’s currently a lot of buzz going around about 4K Ultra HD (UHD) Blu-rays and with good reason. If you’re a movie lover who settles for nothing less than the best quality both in terms of video and audio, this is the format you’re looking for. At the same time, there’s some confusion surrounding this term because hardware manufacturers and consumers alike often use 4K, UHD or 4K UHD to refer to the same thing.

To avoid any confusion, simply remember that Ultra High Definition is the next step from Full High Definition (Full HD) and refers to resolutions greater than 1080p (1920 x 1080 pixels). With 4K resolution being greater than 1080p, it automatically falls into the UHD category, which also includes the next-generation 8K resolution. Simply saying UHD could technically refer to either 4K or 8K. Add to that the fact that there are two types of 4K resolution, one that’s 4,096 x 2160 px and is a cinema display standard and one that’s 3,840 x 2,160 px and is a consumer display standard.

Step 3: It's time to check out the customization and editing options. Some of the options will only be available when you pick a certain profile so keep that in mind. You can start off by changing the name of the output or by picking the titles, audio track, subtitles, and chapters you want to rip. 

Step 4: To the right of all these options that are a couple of buttons you can play with. Since we’re going with the high-quality MKV Passthrough, most of the settings have already been pre-selected for this particular profile and there’s not much we can change.

However, if we switch to MKV.4K.H265.10bit you’ll notice we can modify things like Video Quality, Encoding Method, Sample Rate, Codec, and more. In this instance, we’re trying to convert the UHD Blu-ray to MKV while trying to preserve as much of the original quality as possible so we’re going to stick with Passthrough.

There is the editor icon next to the Advanced Settings icon. You can edit (cut, trim, add watermark and more) the 4K videos in the UHD Blu-ray in your way.

Step 5: Click the folder icon found in the lower left corner to pick the destination of the output file. Once you’re ready to convert the UHD Blu-ray to MKV simply press the green Start button.
