When exporting footage I generally use AME, and I periodically get error messages that talk about increasing the Profile and Level, but I have no idea what those mean or do. I mean, I read the help guide (http://helpx.adobe.com/media-encoder/using/export-settings-reference.html#video_exports_se ttings), but the explanations for Profile and Level are one-liners that explain all of diddly squat. So with what little cryptic info I've found on the interwebses, I've basically blindly adjusted settings til I've gotten something close to what I want or need. I'd MUCH rather like to understand what they are and how they affect my output so I can actively problem solve on my own. Sooo.....
1a.) What are Profile and Level and what do they do?
1b.) What do the different numerical representations of Level mean/do? The range of choices (1.0, 1.1, 1.2, 1.3, 2.0, 2.1, 2.2, 3.0, 3.1, 3.2, 4.0, 4.1, 4.2, 5.0, 5.1) appears random to my uneducated brain, which likely means there is actually a very good explanation and precise specifications for each one.
2a.) What are some real world applications of given settings? What's common/widely accepted and used?
Thanks!
