Processor speed and video

Post by Stephen Hart » Tue Jun 04, 2019 10:14 am

A few new technologies in our house have come together recently, and for perhaps the first time I've confronted an issue with processor speed.
The new MacPro is supposed to be capable of managing several simultaneous threads of 8K video, at a hefty price.

My iPhone Xs takes 4K video (where each frame is 8 megapixels), and the app that goes with my Movi Cinema Robot can to 4K at 60 frames per second, whereas my big camera, a Panasonic Lumix FZ2500 only does 4K at 30 frames per second.

All that is to say that some recent footage from my iPhone won't play well in Final Cut Pro X on my 5K iMac. It stutters from dropped frames, even if I choose better performance instead of better quality. Final Cut has another way to view and edit video, using so-called proxy videos. It makes a half resolution version of a video, and you work on that. It then applies any edits to the original and you can the export the edited original.

But my new MacBook Pro will play 4K 60 fps video perfectly, even in full screen. (I don't have a way to test with an external monitor.)

Bottom Line: Speed matters, especially when you work on processor-intensive tasks.
