I read in the Zoom help about the option: Optimizing a shared video clip in full screen. What does the "Optimize for full-screen video clip" option do in Zoom when sharing one's screen?

I'm looking for an explanation more detailed than it optimizes for full-screen video clip but instead which technical features are activated to make it more optimal.

    Only Zoom could tell you what it really does. I'd guess it switches to a different video codec. – Daniel B Feb 07 '21 at 21:39
  • As it is optimising for "full screen video clips" It probably switches the codec from a low motion, high efficiency mode (RDP like) to a high motion, fast but less efficient mode (video like). We can only guess the internal working of a proprietary tool that doesn't explicitly state what it is doing. Zooms help is patchy and vague at best. – Mokubai Feb 07 '21 at 22:01

Since the question got downvoted here, I asked it on https://redd.it/levtiq, where talones gave me the following answer:

It basically lowers the resolution so that the frame rate can be higher. If you have a basic or pro account it will most likely only be 360p video. With a business or education account you can get 720p or 1080p30.
