Freeze and composite image back on top in Fusion

[Thomas Singh]

I want to use a BSpline to cut out a part of the image, freeze it and track it on top of the same image. How can that be done? 

The idea is to do a paint job on the image, and then composite parts of the original image back on top. The image moved so I need to freeze and track it.

Bring the footage in through an additional Loader. Set the Loader's Trim and Hold Last Frame parameters to make a freeze frame. Mask the Loader and track it on top of the footage coming through MediaIn.

Thanks! Do I need to bring it in with a loader? It´s the footage so it would make sense to simply pipe from the same MediaIn1 source?

You can also use Timespeed with speed set to 0, you can choose the frame with delay parameter.

The Loader gives you the Trim controls. Or, as mentioned, just use Timespeed.
