With video signal that is uncompressed and visually lossless, you’re in charge of what to do with it next. Raw video capture means better qualityįurthermore, when the data signal isn’t compressed, you get better video quality. When your software receives this stream, it doesn’t need to decode it, so there’s less heavy lifting.

And with this type of pre-compressed video, it’s never possible to get back the full detail that was lost in compression.īy contrast, our AV.io family of HDMI capture cards send raw pixel data across to your computer over USB 3.0 (max transfer of 640 MB/s). When it arrives on your computer, the CPU and/or GPU need to work to decompress this image, then re-encode it with your encoding settings. Other video capture solutions compress your video into a container like H.264 or Motion JPG so it’s small enough to fit across a USB 2.0 bus (a medium with a maximum data transfer rate of 60 MB/s).
