Just FYI, last night I imported the ProRes file into Adobe Premiere Pro, and then exported out as an mp4, CBR of 100, key frame distance of 120, and H.264. Same issue.

[Joe Marler] “Could you please re-state what machines you’ve tested this on — the year, model and config if each machine, also what version of MacOS on each machine?”
Tested on various PC’s at work with all browsers…heck, I even threw it at Brave and Opera without issue.
Macs that run fine on all (at least to my eyes) were a 15″ MacBook Pro (late 2015 model) running Catalina 10.15.5, a 13″ MacBook Air (2013 model) running Catalina 10.15.5, and all iOS devices in my house…iPhone 11 Pro Max running iOS 14 Beta, iPhone XR and an iPhone 7 running iOS 13.
My jittery issues seem to be on my home and work Macs: a 27″ iMac (2017 model) running Catalina 10.15.5, two 27″ iMacs (2015 models) running Catalina 10.15.5, and a 27″ iMac Pro (2020 model) running Catalina 10.15.5. The iMac Pro is a beast with a 10 Core processor, 128GB of ram, 2TB SSD, and a Radeon Pro Vega 64 16GB video card.

Thanks. Since I know it is not my video, which is what was worrying me, then I am going to forge ahead. Thanks so much for your help…incredible effort on your part and I truly appreciate it.
What is odd is that all browsers, firebox included, play fine on my 15 inch MacBook Pro and my MacBook Air.

Joe,
Thanks for the help. I opened compressor and followed your directions and added the duplicate with changes to my final cut pro sharing window. I shared my raw timeline using the newly created compressor setting and uploaded the resulting file.
Plays fine in Safari, play almost perfect n Chrome, Firefox is still bad.

I think certain Mac hardware might be my issue.PC’s play fine. My MacBook Pro and MacBook Air play all browsers fine as well I just discovered…it is my 2017 iMac and my 2020 iMac Pro that play jittery in all browsers but Safari. WTH?

I exported the file as normal to an external drive. Attach the drive to a Windows 10 PC and uploaded the video to Vimeo through Chrome. Same issue.
I don’t know what I am going to do.

Should I take the original Final Cut Pro export and save it to an external drive, and then connect to a PC and upload to Vimeo? That may work if there is a bug on the Mac versions? I am going to try that tonight.

I exported as 1080P 60fps (doesn’t look as good) and I uploaded it to Vimeo. Once it finished processing, I downloaded the encoded 1080p file and played it on my Mac…played perfectly. Uploaded it to both YouTube and Vimeo…played jittery.Safari, still good.
I am at a loss…I just don’t get it.

Yes, I can export it as 1080p and upload it to YouTube.
The 4K files uploaded to Vimeo play perfectly in Safari, but still have the jitter in Chrome, worse in Firefox. What is so frustrating is that they play perfectly in Final Cut Pro and the exported file plays perfectly in Quicktime and VLC. The jittery is only happens after being uploaded to Vimeo and YouTube. Even then, it plays perfect in Safari. It is the other browsers that are jittery.
So, to to be clear,…you want me to try and export as 1080P 60FPS, upload that to Vimeo, then download the file from Vimeo and play it on my Mac?

Well, I don’t know why and I hate it, but I think have found my problem. The ONLY thing I am doing differently is shooting 4k 60FPS instead of 1080P 60 FPS. All my videos shot at 1080p 60 FPS are playing perfectly as always in normal window sizes and in full screen. It is the 4K and I don’t know why!
I guess I am going to have to shoot everything over again in 1080p 60FPS because I have to have all browser working for this project. I guess I just don’t understand why Safari pays perfectly. How can one browser be fine?
Anyway, if any of you have any ideas before I set out to shoot all of my footage over again, I would appreciate it.
Oh, and all of this is shot on a Canon 1DX Mark II. Thanks.
