How do i make smooth camera movements?

I want to make camera movments that smoothly move when you scroll and move left to right or up and down. Basically the same camera movments on any game with buttery smooth movments.

If you are making a small cutscene where it goes off the player into another location (such as a boss battle and the camera moves to the boss and back the player), I would recommend Clonetrooper1019's cutscene editor: https://www.roblox.com/library/142371528/CloneTrooper1019s-Cutscene-Editor

Otherwise just look into camera interpolation which is better for projects such as the one shown in the video. Here's a link to the Roblox dev wiki: https://wiki.roblox.com/index.php?title=API:Class/Camera/Interpolate

If you have any problems or questions please contact me. ;)
