Choppy animation in Premiere :(

#1

Hey everyone

I made an animation in Max and rendered it as a sequence of PNG’s. I then imported it to Premiere and rendered it from there. The animation is a simple slideshow of pictures constantly moving across the screen one after the other.
The rendered .AVI from Premiere comes out choppy, as in, the pictures don’t “slide” in a smooth way, it looks as if they’re dragging a bit (or: stopping and then moving a bit, stopping and then moving another bit etc…)

What can I do to solve this? Could this be a codec problem or a framerate problem? I tried using different codecs and I tried both 25fps and 30fps but to no avail…

I would really appreciate your help on this as this is the main problem with my movie, the rest I believe I can solve by myself.

THANKS!

How big is the file and what format is it in, if you’ve exported a file that’s too big then your machine will have problems playing it back and it usually results in a choppy playback.

Its ~200 MB. The only reasons I can think of are framerate/codec… Could the codec be related?

Last time I tried importing my animation png file seq in Premiere CS5 it broke part of it due to inexplicably dropped/missing frames. I tried different image formats, but still the same issue. After Effects worked without a hitch. I would stick with Afx, or another app - stay away from Premiere for this kind of thing.

what type of frame padding are you using?

numbers 1-200? or 001-200?

Talking about my experience, I was using proper frame padding: 001.png, 002.png, ~, 0128.png, 0129.png

It was odd, though - some frames were left out, which resulted in a broken animation near the end. I also tried rendering to *.jpg, but same result.

Using 001, 002… I don’t understand why this happens, it even happens when rendering in 360p or whatever, so its definitely not too heavy for my computer… (Or is it? My computer runs 720p movies that weight 4GB each smoothly, so why won’t it render a 360p movie that weights 500MB smoothly?)

Did you import the frames into a different app, and exported the avi, so you can test whether this is Premiere related problem or not?

And you could try DJV Imaging to review the animation playing from the original rendered frames to test if it plays smoothly. DJV Imaging is excellent for playback of animation work.
