View Full Version : Jerky animations HELP !

05-21-2003, 06:06 PM
When I render animations (targa image sequences) I often get some annoying regular jerks all along the sequence.

I work with 24fps sequences so, I think that the frame rate isn't the cause of the problem. I can't figure out where does it comes from.

Could someone list me the most common causes of jerky animations ?

That would help...

I had exactly the same problem so I can tell you exactly what it is!

It IS your FPS! By default LW renders at 30 fps (it's under options if you want to change it) I'm sure I changed it to 24 fps on one project and so built the anim in Premiere at 24 fps. It jerked at regular intervals so I thought it was something to do with keyframes!

Because I was SURE I'd rendered at 24 fps I didn't think that was the problem, when I checked in LW it was 30 fps! Doh!

Try building your anim at 30 fps.

Hope that helps!

Problem solved !!

It was coming from After FX...
When importing image sequences, the default setup is 30fps.

I forgot to set the "interpret footage option" at 24 fps.
Setting the composition parameters at 24 fps was not enough.

Now everything works fine !:cool:
