Using the same hardware and software setup to run multiple Zoom meetings, I end up with recordings of widely different dimensions, ranging from 640x360 to 2736x1824. I’m trying to figure out what factors impact the dimensions of Zoom converted videos. More details below. I became aware of the issue when –for no explicable reason– after a Zoom meeting the converted video produced by Zoom was 1920 x 2160: that’s a vertical frame (within which the 16:9 ratio was captured, with black bars on top and below).
Current version is 5.4.2 (58740.1105) running on Catalina 10.15.7 but this has been going on for the past three months.
I always use the same settings:
- MacBook Pro 13.3 inch. (display 2560x1600)
- This is hooked on a Dell 24 inch (1920 x 1200): the Dell is the main monitor where all apps are running, including Zoom.
- Meetings are 1-2 hours long, and involve between 5-15 participants
- I always record the speaker view only
- I record locally: as soon as the meeting is over, Zoom starts the conversion and after a while I end up with an MP4 file. Examining that file gives me the exact dimensions of the recording.
- Video preference set to HD
- I record video during screen sharing
- Webcam is a Logitech C922 (1080p)
- If I run a test by myself, I consistently get 1280 x 720 video files
- But over the course of the past weeks, using the same setting described above, I ended up with video of the following dimensions:
640 x 360;
1280 x 720;
1684 × 900;
1920 x 1200;
1920 x 2160;
2736 x 1824
I’m left wondering if the participants themselves do not impact the size of my recordings: i.e. maybe through screen sharing (sometimes the participants share their screen). Any help troubleshooting this would be appreciated.
