ok "real art" wasn't a good phrase to use; I'm not trying to bend the word's definition to what I want. I didn't mean "it's not art by definition" or "if it's not good enough, it can't be called art", just "it doesn't have a ton of artistic merit or take as much talent* as a lot of people seem to think if you restrict your pixel art to using large portions of someone else's".
Sprite editing would be more accurately compared to TV clips strung together to music on youtube. There also isn't as much room for skill in sprite editing as there is in film editing, and it's a completely different value of "editing". Film editing is part of the finished product, not a derivative work. Filming a film and editing it are different processes; editing sprites is essentially just making your own little shards of pixel art but using someone else's as a base for them instead of actually creating something from scratch. Sprite editing is a good start, and can go a fair distance, but you have to start making your own art at some point. (Eventually, your edit is so different that it's mostly your work anyway.)
You can be great at sprite editing, and can put as much effort to it as you want, but making your own pixel art, even basic, is still a step further.
You can be great at putting a piece of paper over someone else's drawing and then tracing it, and can put as much effort to it as you want, but drawing your own things, even basic, is still a step further.
You can be great at gluing bits of a TV show together, but it still doesn't compare to actually helping piece together a film.
I'm assuming the goal is to improve as an artist and not to just pick up some simple form of art as a hobby for some time then lose interest, though.
Also I'm only addressing the first comparison because the rest are stretching it and don't look parallel to me; I assumed this was deliberate to convey "well you're being absurd!" or something.
*I do mean learned talent, not "oh you're just gifted" talent
EDIT: Slso a lot of things (recoloring!) still take absolutely no skill, and I honestly do think that threads pretty much devoted to them should be outlawed.
