Questions about resolution, and exporting.

Hi if anyone can help me I had some questions.

I am trying to make an animation using characters based off of old jrpgs like ff2/3. And While ive already made a few of my own sprites and am currently making a spritesheet for a character i realized there are somethings i need to know first.

Resolution.
Can someone explain this to me? I want to make an animation that I can put up on youtube. I keep trying to read all of these things about resolution but get so confused. For example all i know right now is that my character sprites fit within a 20x44 space. That is the uniformity i am keeping for them. Does this have anything to do with resolution of the whole canvas? If i put a 20x44 sprite on a canvas that scales to double then it should double just fine itself correct? If you can't answer can you please point me to a video that is very easy to understand about resolution. Or is it something i shouldn't even worry about right now while making sprites? is the 20X44 sprite and resolution completely separate?

Spritesheet/exporting.
Second question. Im making the sprite sheets in aseprite. And I had a different aseprite file for my animation. Going frame by frame and animating. Is there a way to save this file as a video file of some kind? What does it mean if i were to try and export it. Is each frame a separate sheet of some kind?

Resolution is only how many pixels can fit in the canvas. 1920x1080 screen resolution means just that there are 1920 pixels horizontally, and 1080 vertically. So relative to that 20x44 is very, very tiny.

What you generally want to do is scale your art up to fit on the screen properly, which is 1920x1080 almost always so that's what you want to go for. So what you do is you divide 1920x1080 by a full number to get a smaller canvas to work in.

1920x1080 divided by 4 for example:
1920/4 = 480
1080/4 = 270

So you put your 20x44 sprite in a 480x270 canvas, where it fits a lot better compared to the size of the canvas, and then you work within that space, and then when you want to export it or put it on youtube you export it with the size increased by 4 (400%), which will then make it fit perfectly on a 1920x1080 (1080p) monitor.

But this is really only for lets say a video game or a video. Otherwise you just have to think about how big it will be visually on a bigger screen after you've scaled it up. If you're just making a character or drawing some random thing you want to post then you don't have to worry about size that much. Just make what you want and you can resize the canvas based on your needs. You have a lot of room to resize it to make it larger in that case.

ok thank you for the reply. I was planning on a video. So im gonna be working at 480x270. Now it seems like a good size to start with. Thanks a bunch
