On these cameras, HDMI is the right tool for the job. USB video quality is often poor where it's supported, and HDMI is there for video output.

These cameras are not made to be webcams. OP is using theirs as one, and that's fine; I do too. But device-side compression for USB video out, a webcam app, etc. are webcam features. They come at a cost, and many camera buyers don't need them.

For those of us using these cameras in these nonstandard ways, we can reach for HDMI, which is the right tool for this particular job.
