Camera animation stuttering

antithing · February 16, 2016, 6:15pm

Hi, I am seeing a strange issue whenever i animate a camera, and then look through it as it plays back.

See video here:

That is a simple animation, the camera rotating in Z, 1 degree per tick. It SHOULD be playing completely smoothly, the fps stays above 60, although it jumps up to 170 and back often. Why am I seeing this strange jerking?

Any help here would be greatly appreciated, I am tearing my hair out trying to figure this out.

Thanks!

Thanks! I have copied your setup, and it looks better, but still has some pops. IS there a way to get perfect playback this way?

I would have to se how exactly are you rotating it, but adding one degree per tick doesn’t sound too good. The rotation speed should not depend on the framerate.

You should be using the Delta Seconds value in some way. Could be with an interpolation node, like RInterp to Constant like this:

Or using a timeline instead of the tick event.

In a new project, I have created a camera and added the bp in the attached image.
I still see jumps and pops in the motion, have a made an error somewhere? How can i smooth this out? Thanks again.
