Aspect ratio of video and how the thumbnail appears when the screen is shared with Zoom

When you share the screen with Zoom, there are various places where the image of the person who is talking appears.
Do you know what determines this?

When sharing the screen with Zoom

Some of the shared materials include thumbnail images of the speaker …

Thumbnail images of people who speak are popping out of the shared materials …

What does this mean?

 

Actually, it depends on the aspect ratio of the shared material.

When the material is displayed in full screen, it depends on the aspect ratio of the display.

 

For example, the display I’m using in my sub has a resolution of 1920 pixels x 1080 pixels.

The aspect ratio is 16: 9.

When you share a full-screen material on this display, Zoom will fill the image with the material and overlay the thumbnail image of the person speaking in the upper right corner of the material.

 

The main display I use has a resolution of 1600 pixels x 1200 pixels.

The aspect ratio is 4: 3.

If you share a full-screen material on this display, the left and right sides will be left over, so the thumbnail image of the person who is talking will be reflected outside the material.

Zoom seems to want to show screen sharing in a 16: 9 aspect ratio.

However, it seems that the shape will change depending on the materials used when sharing the screen.

 

In addition, the size and aspect ratio of the recorded video data will change accordingly.

If you make the material to be shared vertically long and thin, the recorded data itself will be much closer to a square.

I don’t know the exact number when and what size and aspect ratio will be, but the size and aspect ratio of the recorded data will change depending on the number of participants and the materials to be shared.
