Quicktime only plays audio with dash cam micro card
I have tried repeatedly to get video from QuickTime but only audio appears. I am certainly techno impaired but never had a problem before. I just upgraded to Sequoia.

Verify that your downloaded file is 84,692,284 bytes in size, to make sure the download was complete.
macOS should use Disk Image Mounter to open a .dmg file; part of macOS itself. Not sure how that wouldn’t be available to all users?
What movie codec and details does the movie have? You can check them with MediaInfo or Invisor.
For example: H.265 Codec ID hev1 has an error message "This file contains some media that isn't compatible with QuickTime Player" and plays audio only. There is a lossless fix if you install ffmpeg and add '-tag:v hvc1' without re-encoding in the Terminal:
ffmpeg -i input.mp4 -c copy -tag:v hvc1 output.mp4
An easy workaround is to play such movie with IINA.
Matti, thank you for your quick reply! I tried iina but got the following screen shot. Also QT continued to just give audio. HOWEVER, I found Elmedia Video Player and it works perfectly!
