Zoom video always slightly blurry while Camera app is always sharp

[MarkRoberts]

My camera app is working fine, picture is sharp as always. But when I go from the camera to zoom, the picture quality is poor.  I've read online that many seem to have this problem but none of the proposed solutions (more light, clean camera lens, etc.) does anything.

Does anyone have a solution for this or is this is good as zoom gets?

I have begun to have this problem only recently. Picture quality used to be fine, but in the last 2 weeks or so people are telling me that my picture is trailing when I move. This is especially problematic because I am an ASL interpreter. I have tested this on different networks, with different cameras, and the problem persists. I can record a video with the same camera that has no issues. I think Zoom updated something that changed the video stream quality in some way,
