PC build and video card

Post by alang »

New to the forum, I do not see a section that supports PCs used for rips. Do you need a heavy duty PC or can you use a mini, what are the basic requirements? Windows 10? Also what video card is best for playback of 4k UHD HDR. Thanks in advance.

Is there something already on the market that gets the job done? Any suggestions? Thank you.

The specs for a ripping-only machine are actually pretty light. I've done ripping with a Wintel W8 and a USB drive (very low-power machine, kind of like a tablet on steroids), and the ripping speed was limited by the 100Mb network installed, rather than processor speed (it would keep writing to the network for nearly 4 minutes after the physical ripping finished).

Playing HDR.... that I'll leave for people who actual do that.

You will need a card capable of 4K resolutions (3840 x 2160; 4096 x 2160). Does not have to be super high end, but powerful enough to support standard playback on the size TV you will be playing the movie on.

For example, one setup I work on has a GTX 1050TI dedicated to the 4K TV used to playback 4K content and to a certain extend that is overkill.

HDR is typically passed onto the TV. In the aforementioned setup we pass-through HDR directly to the TV. The TV handles that.

However, in PC playback you have additional options that WILL require extra GPU processing power. For example, if you use a renderer like MadVR in conjunction with a player that supports this rendering application. It can get pretty detailed and complicated at this level. As the user is given many additional options to improve playback quality of the content (not just 4K content, but all kinds of video content), but it can require lots of additional horse power from the graphics card as it's GPU assisted. Specially at higher resolutions like 4K.

We wouldn't be able to run MadVR completely maxed out on the GTX 1050TI as it would cause serious frame/performance drops (tested). We would need a GTX 1070 or higher GPU for such rendering.

See this link for additional insight on MadVR renderer.

It's their official support post on Doom9. There may be a couple other renderers available, but this one is the best in my opinion if you know what you are doing or are wiling to spend many hours learning it's features and how to use them properly.

If you are looking for standard 4K playback without any additional thrills, then pretty much any GPU that supports 4K resolutions should suffice.

Does MadVR support 10 or 12 bit?

Thank you all for your replies, very helpful.

Yes. But keep in mind that it's best to do passthrough in these cases.

Meaning, your GPU, GPU driver, and TV would have to all support 10 and/or 12 bit so that they can pass it and then the TV can process the HDR. Have them handle it instead of the playback software.

Additionally, the developer has yet to add support for Dolby Vision and/or HDR10+ metadata. He has said so himself some time ago that he is unsure when/if one or both of these will be supported, but sounds that he may be working on support. However, it could take some time.
