How were you able to turn off compression settings? Mine is greyed out and is set to automatic. I'm also using SF LMS and got the same issue as yours.
Just added a reply. Wasn't sure if you would get the message. So posting it here as well.
Hi Jerico!
When in Storyline. Click on your video & in the Option Window turn Off the video compression.

I found this issue out when looking at my Initial SCORM file. All the Video sizes were 0. (Screenshot attached)
Then when Saving the new SCORM turning off the compression. They all now have size.
