Reducing video size—terminology
Yesterday I shot several videos with my iPhone 13 Pro Max (iOS 16.6.1). Today I'm trying to string them together in iMovie. The lot of them add up to about 15 minutes' viewing time, and I'm afraid the size of the finished product will be too large for streaming.
Well, I'm not well versed in these matters, but I see that I can export a video from iPhotos to something smaller than the original. I click File >> Export ... >> Export 1 video, and the default selection shows "720p." The choices run from 480p to 720p to 1080p to 4K. My problem is that I don't see the same kind of measurements on display in the Info sheet for the video. I see that it's "1920 x 1080, 74.6 MB, and HVEC."
So ... am I starting with a 1080p video? The 1080p that I see as a choice in the Export dialog—is that the same size as what I'm starting with? In other words, does "1920 x 1080" give me the "1080p" that I see in the Export menu?
If this were your project, would you export to 720p, or would you choose to go all the way to 480p? I'm looking to send this project up to YouTube for a few friends to see.
