#I'm rusty enough with vidding and I always hated Adobe Premiere's controls

I suspect I'm going to have to reach out randomly to my fave YouTube vidders (who I have previously never spoken to so yay) to get the answer to this question, but maybe someone following me makes fanvids and I never knew.

Does Adobe Premiere Pro edit compressed video footage without issue? Because 13 years ago, when you got into the fancier (read: paid) softwares, you started running into frames popping up where they weren't supposed to. On a vidding forum (LONG ago passed on to the great big internet in the sky, rip) I learned about compressed and uncompressed footage and that video editing softwares are only designed to work with uncompressed footage (because it's raw and all frames are considered key frames). And the downloaded episodes you download are compressed to make them downloadable (uncompressed footage is HUGE). Compressed footage takes short cuts and only designates certain frames as the "key frame" and if it's not a key frame, it might pop up where it's not supposed to be when you're editing with it. So I learned this bulky method to sort of fake uncompress the footage? and the stray frame problem went away.

Long story short, there's no way every fan in the world knows these kinds of technical details (I don't know the technical details; my explanation was shit) and the method I used in 2009 isn't supported in 2020, so!

How the fuck does everyone make these really high quality vids with no stray frames???

My only guess is Adobe Premiere Pro deals with compressed footage more cleanly than Sony Vegas did (and does, cause in 2017 I tried editing a Ghostbusters vid and immediately had a stray frame problem). But I would love to have that confirmed before I shell out money and attempt to learn a new software.
