How to make an effective Cutscene?

So, I wanna make a cutscene like this.

The problem is in the Animation. So, if I upload every single cutscene animation into Roblox that will be super hard and not organized.

so, is there any solution?

Pretty sure those are not “Animations” but rather stored CFrame’s to position the Camera.
When the cutscene activates it would just loop through all the positions and tweening configuration you would have and use the TweenService to move the camera to those positions smoothly.

There are a lot of tutorials to do this, a good one to give you an idea of what I am talking about:

the problem is on the character Anims. since uploading everything to Roblox is hard and not organized.

Oh I see. I thought you were only talking about the camera work. Unfortunately, everything will have to be manually scripted in, and ran at key points in the game. Something like this is indeed a lot of work, and as for organized… well thats just up to how you add in this feature. Make sure things are named how they should with easy to understand titles so you know what goes where.
