Pardon my ignorance, but lack of knowledge is kind of the point of these forums, eh?
My internet searches of "What kind of video compression does YouTube use?" have generated the same responses: H.264. But there are other things going on I clearly don't understand.
For example, I have a music video on my MacBook Pro that I edited in FCP, and output as 1920x1080HD, 24p, H.264. Duration is 3:39, and file size is 337.7MB. It lives on my computer as a .mov file.
If I take that file, upload it to YouTube, then download it back from YouTube using iTube Studio software I get a surprise. The post-YouTube crunch, according to Quicktime is also 1920x1080, also 24p, and also H.264. But it's a .mp4 file, and it's size is only 83.2MB. What?
My child's-level understanding is that .mov and .mp4 are just the video file wrapper standards, and it's the H.264 performing the true, lossy video compression. Yet, despite both files showing H.264 compression, the file after uploading and downloading from YouTube is less than one-fourth the size, while still allegedly maintaining the same 1920x1080, 24p resolution? There's something huge I'm missing here.
Thanks in advance!
