How to match the last and first image of an effect (wave warp)

[Ziomix]

I try again and again to match the last and the first image of my effect (wave warp on hair so that it waves) so that when the composition comes back to the beginning, there is no cut but I still can't get it to work? Please help me ?

Did you try to copy the first keyframe and paste it as the last one and continue to the next one?

The easiest way is to ensure the Wave Speed property is an integer and your timespan is an exact multiple of your comp's framerate.

You can then combine nesting + time remap to adjust the speed of the waves.

A more robust formula will be -
timeSpan for LoopPoint = 1/WaveSpeed * frameRate

Another formulaic solution is to set Phase Angle to 256 degrees - more info here -

OMG Thank you very much, so I put a keyframe at 0 at the beginning and at the end, it works perfectly! It was super simple but with my little head I didn't think about it again, thank you !!

You're welcome!

hi! Having trouble with looping the wave warp. where did you add the keyframes?

Found another solution - set the wave speed to 1/(length of comp) so if your comp is 6 seconds, set the wave speed to 1/6.

Ok thank you for your answer but I dont understand your explanation, the only way to get a loop is to set the wave speed to 3 but it's too fast. And what do you mean when you say " set the wave speed to 1/(length of comp) so if your comp is 6 seconds, set the wave speed to 1/6. " ^^'

Thank you anyway bro 🙂
