Is there any way to move the camera, or any other drawing in 2s instead of 1s?
I have Harmony but it must be the same for Animate, if there is something, no?
Just put a keyframe on the 2 to keep it in the same spot.
If you have a Camera Peg you can go in the 3D path properties > Velocity curve. Open the editor for that curve and inside you will find a icon to Hold Value Editor. Set the start and end frame and the step value on 2’s.
If you are not using the 3D Path mode but are in Separate mode or you want to do the rotation on 2’s for example, you would then have to go inside each individual curves(x,y,z) and do the same Hold Value.
