I'm having trouble understanding video compression. I'm a new instructor. Udemy said my demo video was stretched their recommendations use Vimeo and re-export the video I didn't need to re-record it. I'm afraid I can't explain it but some how I uploaded my demo video onto Vimeo then It downloaded to my phone then I uploaded to Udemy and I see the video and I'm waiting for their feedback however under the the video it says video in queue. This is all new for me I'm trying to understand video compression and fixing it. I could some help any suggestions for a new instructor would be much appreciated.
