How to retime Alembic camera

[Jawla]

Hi Guys I have a Maya scene exported out as Alembic cache. It has a very fast moving characters and camera. I want to retime the cache and slow it down. It was easy to retime the characters with Timewarp but how do I retime the camera Please Help.

Also what would be the best solution to sim fast moving objects Substeps or retiming the shot.
 

Thanks

My first instinct would be to use chops. Can you post a scene?

I'm stuck with the same problem, any easy way to do this in Houdini?

Here is someone that is using an approach with custom script:

for alembic camera there are 2 Frame related parameters Frame(adjust the start frame to match the fps)  and Frames per second(multiply with the amount of slow motion needed like( 1/2 speed means 2 and quater means 4)) of the Alembic  Archive obj  file adjusting them will make the camera/animation/whatever inside gets slow motion. probably duplicate the alembic cam and rename as slow motion
