Is this video available somewhere so we can try to reproduce the problem?

The video is just simple download from youtube in HD quality.

The video is just 7:30 minutes and 110MB big.

What I suggest is download any 10 minutes video from youtube, in several resolutions:

  • 720, 1080, 2K, 4K and test the CPU and RAM utilization.

I tried. I haven’t been able to repro your problem. We will see if some other user can help us pinpoint the issue

@den, are you running this in a VM? Or on non-Mac hardware? I’m wondering if Obsidian can’t rely on the graphics processor.

I agree with @datum. When I play videos in Obs, it’s the GPU that does the work. I wonder if you have some codec problem or an older computer/gpu or a mix of those. I wonder what happens when you try to play those videos directly in chrome (by opening the files in chrome not through youtube)

:smiley: No it is native Macbook 12". Fresh clean installation of newest Mac OS Big sur.
I need to stress that video is downloaded from youtube, not playing it thru iFrame.

Another test… same video is playing in Obsidian
