Hi all, when adding 4K footage from my recently-acquired Sony ZV-1 to my sequence, the view in the program monitor freezes. I expect my MacBook (mid-2015, 2.8 GHz Quad-Core Intel Core i7, 16 GB) to struggle with 4K footage, but not to keel over so completely. I've created a proxy file and that seems to work fine, but as soon as I press Toggle Proxies it's game over. The view simply doesn't update. I can switch to another timeline, I can theoretically browse, but there's now update in the program monitor. So I seem to have a basic problem with this 4K footage, and looking at the Activity Monitor, there's no great overload of CPU.
Now my question. I want to create some tutorial videos in 1080p. I'm a guitarist, and I want to create a zoomed-in portion for my left hand. So the idea is to have a duplicate of my clip at 250% of the original size, with an opacity mask so I get a circle of my magnified hand. Of course, using 1080 footage, the magnified portion looks a little weedy. My idea was to use 4K footage on a 1080 sequence, with the thought that the magnified portion would look better. Is this daft? If the 4K footage is resized to the dimensions of the 1080 timeline (showing I guess at 50%), does that negate the idea that the enlarged portion would have a higher resolution than an enlarged 1080 clip?
I hope that makes sense, many thanks to anyone who can shed light on either issue. If the answer to the question about 4K on a 1080 sequence is that it's not worth bothering with, then the first issue about basic compatibility with my machine and 4K footage generally is moot.
Error or problem
Freeze or hang
Great, that makes sense. These are YouTube videos, and I can see that 4K on a 1080 timeline gives me the option to magnify with no apparent loss of quality. Thanks for your help, I guess shooting in 4K will be worth it. This must be quite a common thing. @Ann Bens does it 'feel' cropped, because of the optics? Do you tend to shoot any wider in 4K because you always have the option to zoom a bit in post?
