4K Ripping Service from DIGIRAW

4K (UHD/HDR) ripping service.

We knew 4K UHD would take off, and we knew our customers would encourage us to get on board.

Our favourite format is the lossless MKV which savours all that fine quality, and equally important DTS, DTS-MA and TrueHD / ATMOS audio too.

4K format-shifting

To understand why the MKV is our favourite, let's make a few comparisons.

Digital content sellers, renters and general streamers.
It all comes down to visual and audio quality, bitrates!

Now, don't get us wrong, those digital content providers can pack a quality compressed punch as long as your internet speed is adequate.

Digital content sellers must appeal to the broader audience and consider bandwidth constraints and data allowances. That means they have to compress their video files, and while some would say Netflix does better on some titles over iTunes, and vice versa, compression will inevitably cause degradation (quality loss) and audio compression plays a huge part!

A 4K (UHD/HDR) feature on a disc can easily exceed 50GB, and H.265 mp4 compression can reduce it to 4GB to 7GB. So what gives?

Visual | Reduced quality/degradation when compressing.
It's something that in general is more noticeable when close up to the screen, which in theory is what 4K (UHD) is all about, but compression can smooth out the grain a director and such like intended. Colours, especially black may look a little more grey, others may even be washed out, and some scenes can be a bit skittish from time to time.

The Apple TV 4K box upscales lower quality which is very smart, but the upshot is while compressed 4K content may look acceptable, it will never match that of a disc, and especially for sound.

Compressing audio for an average boom bar, or when listening with your TV speakers is fine, but if you're running a decent, if not high-end home theatre/cinema setup, streaming compressed audio will be way under par.

Visual Audio:
Sound is immersive and may account for half the features overall file size. MKV lossless (no compression) remains our favourite and supports High Dynamic Range (HDR), TrueHD, DTS:X and Atmos object surround sound technology.

Will DIGIRAW offer a compressed 4K (UHD) mp4 H.265 format?

Yes, and we do, but because you are less likely to need to stream 4K over the internet remotely, we are not going to be as overzealous on compression. For example:

Visual compression will be limited.
Audio passthru, zero compression for DTS, DTS-MA.

Want a compressed file but also TrueHD, DTS:X and Atmos audio?
In this case your container file type will need to be MKV.


Processing power within our Studio has a lot to do with price and right now, ripping to MKV lossless is a lot quicker, and requires less computing power, making the cost of a 4K 100% clone quality conversion to mkv much more price advantageous when compared to a compressed H.265 mp4 version.

H.265 mp4 or mkv can take 15 hours to complete. That's a long time to cover our costs.

4K (UHD) MKV Lossless | £8 p/disc

4K (UHD) H.265 mp4 or mkv | £15 p/disc.

4K or not to 4K, that is the question!

Media Servers/Players | How to play your 4K content.

At this time, 4K (UHD) Direct Play Video Support via Plex requires:

  • Container: MP4
  • Resolution: 3840×2160 or smaller
  • Video Encoding: HEVC (H.265)
  • Video Frame Rate: 30fps
  • Video Bit Depth: 8
4K content which does not match the above properties and Plex will transcode to 1080p. Transcoding 4K content is an intensive process and will require a powerful computer running Plex Media Server.

Playback | Plex to Apple TV 4K
Because Plex adopts the tvOS player rather than develop it's own, and the Apple TV does not natively play MKV unless the video within shares a compatible codec, 4K MKV will be a challenge.

Plex Media Player app
We can confirm PMP on your computer plays flawlessly and our tests confirmed with no transcoding, no direct streaming, just pure direct play.

At present, the Apple TV 4K can not pass object surround sound such Atmos through third party apps. The Nvidia Shield TV can and sounds fantastic.

With the MKV lossless in mind, and with there being many media servers, apps and computing power/networking considerations, you like to pay for a one disc service to test your home configuration first.

contact us if you would like a single 4K (UHD) service. You own your disc and we will return it with your digital file.
