Canon and Nikon do too. In practice, the quality bump is nice, but we are still talking of a fairly low res/bit rate when it gets through Zoom so the end result is fairly underwhelming. As far as what the other people see on their wnd.
Yeah.. both Zoom and Google Meet have >720p video but the bitrate especially on Zoom is a travesty, 600kbps/1.2mbps stream with all the different resolutions in the same stream.
The codec situation with h264/HEVC/vp9/AV1 software/hardware encoding is a mess. Hopefully we'll get wide hardware support for AV1, although it might take a while.
