However, the AVerMedia Live Gamer 4K offers RGB decode modes throughout, and the Live Gamer Ultra offers it for 1080p60 as well! Typically this is reserved for the very expensive and high end cards from the likes of Magewell, BlackMagic Design, and AJA. Elgato does not recommend using these modes and neither do I.įull 4:4:4 RGB support in general is pretty rare to encounter on capture cards in general - both due to cost and to bandwidth requirements. 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. They’re emulated (or simulated?) from the 4:2:0 color space that those devices primarily operate in. color spaces: 1, 2, 3)Īlso I wanted to point out that current drivers for Elgato capture cards may show XRGB/RGB modes in OBS Studio - however these are not real. There’s a specific plugin for this integrated for only the original AVerMedia Live Gamer HD, but does not apply to anything else.) (And no, this will not allow you encode your OBS stream using the capture card’s encoder. It is not recommended to use these modes. “P010” is a compressed color mode for HDR encoding from HDR-compatible capture cards (namely from AVerMedia).Īny capture card (such as the original Elgato Game Capture HD) that shows a “h264” decode mode is likely exposing the on-board encoder’s feed from the card and is going to take even more work from your CPU to decode prior to encoding, cause even more latency, etc. The “UYVY” mode is essentially the exact same as YUY2. Do note that the native applications respective to specific capture cards may only allow or utilize one of these modes. Here are the supported (and functional) decode modes exposed to OBS Studio from the capture cards I have tested.
