Avermedia captur card12/21/2023 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. Uses much more bandwidth than any other mode.Best possible quality image, improves scaling and final encode quality.RGB (XRGB) - 4:4:4 completely uncompressed color and data stream.Requires less bandwidth over USB/PCIe bus than YUY2 (more than MJPEG), should have less system resource impact as well - unless OBS is set to RGB mode or something (in advanced settings).YV12/NV12 - 4:2:0 color space, uncompressed data stream.Usually through UVC protocols, MJPEG is 4:2:2.Increases system resource load and latency. Lower bandwidth over USB/PCIe bus, but requires your CPU to decode the stream before re-encoding on your OBS canvas.Literally “Motion JPEG” - it’s JPEG (like the photos) image compression.Requires more bandwidth over USB/PCIe bus, but has minimal system resource load and latency.This is the most common, and generally the target you want to aim for.YUY2 - 4:2:2 color space, uncompressed data stream.These are color compression formats (not to be confused with data compression) that affect the bandwidth required by the video feed through the device, as well as the total image quality. Some buyers are looking for capture cards that provide specific decode modes to the user. Keep in mind that this is simply a snapshot of things at the time of posting, whereas this Resource page will remain updated. I have posted a breakdown/walkthrough of this Resource to my YouTube channel - this explains each of the charts, some of my reasoning and thinking process, etc. Have a capture card you want me to test? Check out the last section in this guide. I only have access to so many capture cards at this exact moment, but I’m constantly reviewing more, and am trying to test as many as possible. This will be an evolving project - I will be testing every capture card I can get my hands on moving forward and updating this guide along the way, potentially for years to come. IN THIS RESOURCE: I will provide extensive documentation about the connection types, supported decode modes, supported resolutions, frame rates, passthrough, and input latency (to preview) of every capture card I have access to. How to submit capture cards for testing.
