Camera Viewport 2D Pan / Zoom

Recommended Posts

Hello,

I'm trying to model an environment for a drone shot that has been 3d tracked. RIght now I have a 3d camera and some locators to help position things inside C4D and also I have a background object with the drone shot sequence playing in the background of the viewport as I scrub in the timeline, everything aligns properly. My issue is that since is an aerial shot, things look small and I need a way to be able to zoom and pan in the viewport without affecting the camera so I know what I'm doing. To be more clear, imagine that you take a screenshot of the camera viewport and then you use that screenshot in Photoshop to zoom in, pan or zoom out. Hope that makes sense.

 

Thanks for reading.

Hey there,

Film Move, Film Magnify & Film Zoom does what you want but I find these tools confusing sometimes.

I'll make up a simple rig in xpresso that does what you need and post it shortly.

I'll probably make use of it myself one day.

Here's a simple rig that does what you need.

Click open the xPresso tag and there is a node that has some instructions on what to do.

 

Rock on.

  • So nice of you, really appreciate. It works how it should, do you know if I have to do something in order to get the background to move with the canvas?

    Cheers

    This seems like a strange question based on the fact you are using tracked footage, so I would assume you wouldn't want it to move. If you actually do, if you've used a Background Object, that remains static, so if you want it to respect the Camera, you'll need to use a Plane instead as a background and make it large.

  • The reason why I need the background to move with the canvas is because that is the reference I need to see to model the environment, if I 2D pan-zoom it should follow the 3D model. I think this is how it works by default in Max and Maya.

    I'll try using a Plane, thanks.

    A plane thats the aspect ratio of your footage as a child of the tracked camera but not the zoom camera would do what you want I think.
