Does anyone know what is likely causing this issue? Jerky video playback from within this forum; same video direct on youtube plays smooth (all on a Mac)

This is almost certainly a computer question or inquiry but thought I'd post it here since I've only noticed it occurring with the MavicPilots forum. I've been a subscriber to the forum for a number of years and enjoy seeing what others are doing with their Mavics. I've noticed that frequently when I click on an embedded video the video starts playing and within 5-10 seconds the video becomes "jumpy or jerky" and the screen brightness flashes every few seconds. If I move the cursor every few seconds on the screen the video plays smoothly. If I choose to watch the video via youTube, the video plays smoothly for the duration of the clip. I have not observed, one way or another, whether the same behavior occurs with Vimeo clips posted on the forum. The computer on which this is occurring is a mid 2015 MacBook Pro with a 2.5GHz Quad-Core Intel Core i7 and 6 GB 1600 MHz DDR3.

Does anyone have any suggestions for what I can check in my computer's settings?
 
YouTube re-encodes your footage to a better codec for streaming. What codec is being used on your Mac. H265 is not played well on most older, lower powered Macs (or PCs). A hardware decoder is required in both cases for smooth playback. H.264 should work much better.

I think it may have something to do with the way You Tube encodes videos. I have just about given up on You Tube since joining Vimeo and have never experience that problem. When I posted to You Tube it would take several hours to become focused and set in. My Vimeo uploads are fine from the start. Also, I find that whenever I watch a You Tube I always have to go to the cog wheel to boost the video to its highest resolution.
