Hello community,
I have a match move tracked alembic camera imported in my scene that I need to modify. However, I cannot see any keyframes/curves.
So, first of all, how can I extract the animation data of that camera and then bake that as curves onto a houdini camera?
Then, when I have the animation curves/transforms on my houdini camera, how can I reduce that dense data into much fewer keyframes?

I have some idea that this could be done with chops, but I have absolutely no clue about how that would work, so any help would be great. Perhaps there already exist some detailed explanation somewhere? Someone has done this already and has an example file?
And, if there is an even simpler way than chops, what could that be?

Thanks,
Dag

Hey Dougie0047,

ok here is how I do it:

1. copy your camera in the .abc hirachy.
2. Delete any expressions on parameters it might have
3. Cut and paste this new second camera at OBJ level.
4. create a fetch node and point it to the original .abc camera(make sure parent transform is on)
5. make your new camera a child of the fetch node.
6. create a bake animation node in ROP context. Point it to your new camera.
7. bake the animation with the ROP bake animation node.
8. Now you can edit the keys on the new camera. For reduction select the keys you want then press the right mouse.
Choose to bake the keyframes of the selected segment. make sure the preview is on. Adjust Resample first to your liking.
