This function tweens the Camera in a linear fashion towards a new Camera/CFrame and Camera/Focus over a given duration, for example:

local camera = workspace.CurrentCamera
camera.CameraType = Enum.CameraType.Scriptable

camera:Interpolate(
	CFrame.new(0, 10, 100),
	CFrame.new(0, 0, 100),
	5
)

Throughout the tween, the Camera|Camera’s Camera/CFrame will be orientated towards the Camera|Camera’s Camera/Focus.

When the tween has completed, the Camera|Camera’s Camera/InterpolationFinished event will fire.

If this function is called while the Camera is already tweening the older tween will be stopped (without firing Camera/InterpolationFinished) and overridden by the new tween.

Interpolate can only be used if the current Camera/CameraType is ’Scriptable’, regardless of whether the default camera scripts are being used. If it is used with any other Camera/CameraType an error will be thrown.

You are advised to use TweenService to tween the Camera instead as it is more reliable and offers a variety of easing styles. See below for an example:

local TweenService = game:GetService("TweenService")

local camera = workspace.CurrentCamera
camera.CameraType = Enum.CameraType.Scriptable

local tween = TweenService:Create(
	camera,
	TweenInfo.new(5, Enum.EasingStyle.Quad, Enum.EasingDirection.Out),
	{
		CFrame = CFrame.new(0, 10, 100),
		Focus = CFrame.new(0, 0, 100)
	}
)

tween:Play()
