    Hey, I created this image by exporting a video as image sequence then pulling in the images as single frames for a fashion film I am working on, and the effect is really nice and dream like and the director loves it, accept I have loads to do and this feels like a huge waste of time in its current workflow. What I would like to do it take duplicate video layers and offset a freeze frame based on index, that way I can avoid the laborious task of exporting as an image sequence and then re importing. I wondered if anyone had any ideas for the expression I would need for this. I am fine with other values but I am struggling with getting anything working in the freeze frame offset. I still want it to feel rich and vibrant and ghostly so not a simply echo effect, this is much more subtle. Anyway, any tips would be greatly appreciated. I like the idea of utilizing the markers as a trigger. Forgive my ignorance, I am normally confident trying to piece together expressions from various sources but this has my head scratching.

    Cool effect. Something like this maybe for time remapping:

    if (thisComp.marker.numKeys > 0)
    thisComp.marker.key(1).time + (index-1)*thisComp.frameDuration;

    It references the first comp marker.]

    Thanks Dan, I will give it a try this afternoon, with the director this morning discussing changes. So may all change anyway 😉
