What I have is a file recorded with OBS into x264, and the recording settings are NV12 pixel format, colorspace 709 and limited range, see Recording only, using NVENC, I noticed that my resulting MKV or MOV file ends up with slightly different frame-rate when using I444 instead of NV12 for Color Format; this can confuse editing software but I'm not sure what other problems it may cause. Using them may result in a solid color screen, washed out view, or just add more resource load to your system as the driver is taking the 4:2:0 color feed and converting it to the emulated RGB mode and then OBS has to convert it back to NV12 for your stream. On the game PC, in OBS choose nv12 and 709 in the settings in the advanced section, capture the screen, window or game. OBS outputs a washed out image with incorrect levels (the background should be full black) while Avermedia's RECentral4 captures look correct when using the same full/full settings: Unless I'm doing As you can see, MJPEG has the worst color compression, compared to NV12 and Elgato 4K Capture Utility.

As far as I have already learnt, NV12 is designed to be as much compatible with GPU memory layout as possible. Info Color format: NV12 means Y’UV/Y’CbCr 4:2:0 chroma subsampling (chroma resolution halved in both dimensions), which is what OBS always uses for streaming output (see issue #3517). They support multiple video formats, with RGB, YUY2, and MJPEG being among the most common. RGB provides the most detailed colors, but with overhead. Set your video card to output full rgb or full ycbcr set obs at color format to record full range , nv12 or rgb, tell the encoder that it's full range video The last say has the encoder - in older versions of OBS, I was never able to actually create a real lossless video with NVENC - it always created a 4:2:0-encoded video (NV12), no 4:4:4-encoded (RGB).

I first noticed when taking clips into @Tomasz Góral Side note: theoretically, the NV12 vs RGB bitness comparison is incorrect because it is different things. It looks good, but it defeats the purpose of paying over double from the C920/C922x. How to get through this? This is due to your color format settings, OBS defaults to NV12 for anything other than lossless. Setting RGB will make recording while streaming impossible, due to it lagging so hard. The color format can be modified in Settings > Advanced, such as changing default NV12 (8-bit) to P010 (10-bit). Thus resulting with no additional conversions during encoding. With this format, skipped frames due to encoding lag is extremely high (>90%) (you can see this stat in OBS via View > Docks > Stats). It’s pointless to use for streaming. I have the color space set to "Rec. I installed RECentral and the only thing could find was in the Settings => Capture Device => Bandwidth test where the table of supported resolutions filtered by encoder type; I got a similar list to OBS but no mention of depth.

But I want to know, when the monitor is 8bit and the color format is set to P010, whether OBS will directly convert 8bit RGB to 10bit YUV instead of converting to 8bit YUV first and then expanding to 10bit YUV. I found that recording in i444 or RGB made the reds look a lot nicer. Within Settings / Advanced / Video, which Color Format (either NV12, 1420, 1444, RGB) should I specify/use in order to have the HIGHEST 4K Resolution?

Video Settings) I444, for lossless recording, meanwhile converting this to NV12 for streaming platform compatibility? Thanks in advance. NV12 means Y’UV/Y’CbCr 4:2:0 chroma subsampling (chroma resolution halved in both dimensions), which is what OBS always uses for streaming output (see issue #3517). This article identifies the 8-bit YUV formats that are recommended for video . Here are the possibilities I tried: 1) NV12 – 709 – Partial –> Things are close to what is on screen. Therefore I'd much appreciate it if someone can give me some tips about where I The setting in the device just determines which one it outputs, and the one in OBS determines which one it encodes to. I was able to see a difference in CPU usage. So on my monitor I use 10bit video output. If you setup other subsampling - conversion turned on automatically. Some encoders do not support RGB (I444 etc), so NV12 is forced (in most cases). If I set it to partial and 601, they are very dark, almost too dark. In order to make it look good, you need to use NV12 or YUY2 for the format in OBS, but even then, it maxes out at 1080p30.

And I wanna record the game sessions I do from time to time. You can capture in SDR in properties, but it is not necessary or OBS does the tone mapping automatically. What happens when your source is using the full RGB range, but the capture card or OBS Studio is set to limited RGB range. 2100 These combinations are not valid. It is yet another variant where colour information is stored at a lower resolution than the intensity data. It's also worth noting that encoding full chroma with either of those two options will be more CPU heavy, and result in larger files. I just > The source in OBS is "digital data" (video or audio) and they can be "any" format - thus, OBS converts all color spaces (sample rates) to same base before data can be encoded to new stream (file).
