Will rotating squash the picture?

At 90 and 270 degrees the output frame itself is flipped — a 320×180 video comes out 180×320. Leaving the frame as it was would squash or crop it.

Yes. The original audio is carried over as it is — only the picture is redrawn. Turn off “keep the sound” if you do not need it.

Can I do something else while it captures?

Keep this tab in front. Move to another tab and the browser stops drawing, leaving that stretch as a frozen frame. If that happens, you are told once it finishes.

What format does it come out as?

webm. Current devices and programs mostly play it as it is.

Where does the video get uploaded?

Nowhere. It is handled inside your browser only.

Stands up video shot with the phone held sideways. Rotating 90° swaps width and height with it, so nothing is squashed or cropped. Mirror flips are there too.
