Do proxies not play back well if the source footage is variable frame rate? I have an old GoPro clip in a 23.976 fps sequence. When I turn on the proxy, it doesn't play back well. The original GoPro footage says it's 30.01 fps (which makes me think variable frame rate). The proxy is 30 fps ProRes Proxy.
The same thing happens with screen record footage for which proxies were made.

Transcoding from variable frame rate to constant frame rate is straightforward. There's not really anything to mess up.
Have a conversation with your online team about how they want the source footage handled. It's my experience that anything incorrect about a file means the file gets kicked back. The frame rate, the scan method, the frame size, the CODEC, and audio settings should be correct. If you're not sure about the settings you're using, send a test file. If a spec sheet seems unclear (they're not always well written and sometimes include too much), ask for a file that's at the correct settings that can be used for comparison.
For broadast in the United States, all footage that goes to an online team should be at a correct frame rate (constant 29.97 or constant 23.976). And an effort is made to not mix these frame rates in the same Timeline.
