Welcome to TVPaint Community forums !

Hi,
I'm on a Mac using Monterey OS 12.5, and TVPaint Animation 11.5.3 Pro.

I have a single drawn object on a layer that I want to move using the KeyFramer. I sourced the layer and applied keys for translating the object down and rotating it. When I preview the animation, I see two images of the object, one that remains in the original position, and a second one that moves down the way I want it to. I only want to see the image that's moving. I can tell that both images are on the same layer by hiding and revealing that layer. When I apply the FX stack and export a video I still see the 2 images of the same object. I've attached a video of my animation.

In the Source tab in the KeyFramer, I have Pre Behavior and Post Behavior set to None and Anim set to Normal. Do you have any suggestions for me?

Thanks,
Jay

It is recommended to always use the keyframer on an empty layer only. This way you 1. avoid to destruct some previous work, and 2. you now can set the source level to invisible or a low opacity value.

Use your single object (the key in your example) as a SOURCE image for the Keyframer, rendered on a different layer. The Keyframer's source image can be a layer , or in the Image Library , or a separate TVPaint project.

Create a new blank layer. In the Keyframer go to the Source tab. Set the source to your image in the Image Library , or on a layer , or a separate TVPaint project. Now set your keyframes for the move and click Apply FX Stack to render the move on the new blank layer. The original source image remains unchanged so you can re-do and re-render the move later on a new layer if for some reason there need to be changes made.

Image(s) stored in the Image Library Folder as source in Keyframer:

The source image in the Keyframer can also be an object that you have selected and cut to a Custom Brush.


This tutorial briefly demonstrates how to create a Custom Brush from an object in TVPaint and set a custom Pivot Point handle on the brush, save the new Custom Brush to a Custom Tool Panel , then go into the FX Stack -- KeyFramer , and set the KeyFramer SOURCE as the Custom Brush. You can then Keyframe the Angle to animate the object pivoting from the custom pivot origin point that you set on the Custom Brush.

David: Judging by this detailed, crystal-clear explanation on using the KeyFramer FX (and the dozens of other, precision "how-to" replies you've posted to the forums) you must be a very good teacher! When is your book coming out?
