Looping 4-frame pixel animations with weird bugs?
Hello everyone.
My first post here in many years.Ok, I’m currently doing a arcade-game look-a-like music video with a lot of pixel-sprite animations of various frame lenghts.
When I tried getting the first main pixel-running-man animation to loop I ran into odd problems.
First of all I did a 4 frame animation in a comp.
Then I move that comp to the main comp.
Applied time remapping to the anim comp and then chose the loopOut(type = “cycle”, numKeyframes = 4) and extended the layer running length.First I get the classical 1 frame missing after 4 frames after that I get the “empty” frame effect sporadicly here and there but not in any specific order. I tend to notice them specially somewhere between the first few seconds to 40 seconds.
It confuses me a lot, even TimeRemapping confuses me 🙂
Any ideas how I might solve this very annoying dilemma?
I’ve tried reading different articles about this but nobody mentions running into more empty frames. I’ve a newbie when it comes to all this.If somebody has little time over please look at my AE CS4 project file with the included animation (it’s only 24kb zipped)
I’ve created a short link for it https://bit.ly/9Iv6j6Thank you for any help.

After you enable time remapping, go to frame 3 and set a keyframe there (don’t change the value). Then go to frame 4 and set the value of that keyframe to 0. Then loopOut() should do the trick.

Thanx Dan, it worked like a charm! I never understood this properly in your old butterfly article. Thank you very much!
A little follow up question. Do I have any way now of controlling the speed of this or would that require another pre-comp and TimeRemapping? Just for tests sake I tried what happened if I moved the keyframes futher away but it just gave some funky behaviour 🙂

I think the way you suggest would be the easiest, although it should be possible to write a different time remapping expression (one that doesn’t use loopOut()) that calulates the current frame based on some external control (like a slider). You’d have to use linear keyframes on the slider and the code would be messy accumulator type thing, but I think it could be done.
