Smooth camera movement unrelated to low resolution

I am working on a game with a base resolution of 192x108

This link perfectly shows exactly what I’d like to achieve, and I know someone has already posted this years ago but it seems like it went unsolved

An idea I have is rendering the area to a viewport using the Sprite Snapshot extension and smoothly moving the camera across it.

Would something like this be possible?

Are you trying to do something like this?

Not quite, I was looking for a way to have the whole game rendered at a low resolution so every object and particle is snapped to a clean pixel grid, but have the camera able to smoothly move between pixels so it isn’t jittery.

The thing about game making is it’s a let’s-try-it hobby. If you want to know if something will work, you give it a go. And if it doesn’t go according to how you expect, then figure out how to modify things so it does go how you want.

If your camera move smoothly and your character doesn’t, it will look like he’s shaking back and forth.

That’s the jittering I’m talking about. What I was thinking of is having the scene rendered at a low resolution and put into a viewport where the camera would be smoothly moved across said viewport because it is upscaled. I don’t know where I would begin with this though. You can see what I’m aiming for in the link

What I meant is that if your camera scrolls smoothly, all moving objects should also move smoothly or there will be jittering.
What you can do is making sure that moving objects stop exactly on a big pixel.
