Hello StarOfDoom and welcome to TASVideos!
You seem to have misunderstood what the submission page is for. It is
only for optimized TASes. You realized that it is hard to reach the levels of optimization of the current TASes of this game. Even so, try to compare to them while TASing. You will learn new techniques to optimize your own TAS.
Then, when you are pretty confident that your movie isn't "just for fun" and when you are sure you can't further optimize it,
then you can submit the movie,
not before that. Did you see the text at the top of the submission page that said:
please ensure that your movie [...] beats all known records if going for speed. And if you read further, you can see:
If you are simply looking for a place to store your movie files for distribution to other members, please consider user files.
In short, don't submit sub-optimal movies, try to be as optimal as you can be before submitting, and if you are looking for feedback use the user files.
