Figured this one out… Somehow the VFX person messed up the timing and exported the sequences as 30fps. Not sure how they did that as you’d have to go out of your way to re-time an image sequence but hey… It is still confusing how selecting 30fps, 60fps, etc has no effect on the clip duration in Resolve. I suppose it automatically plays the images at one frame per frame of your timeline’s time base. Makes sense. Thanks for your help anyway.
