Another test and after many tweaks with comp settings I finally get the correct size output (needs to be 1024×576 square pixels) I have moved and slightly resized her, and also tried to get the gradation of timing correct.

I would still like to get them finishing in the same spot, but will need to apply the brain seriously as I haven’t got a clean bit of footage looking the same way with no-one in it so that I can extend the end full shot to accommodate the extra little bikers.

I would like to add 4 more bikes to this scene, 9 just seems the right tempo for it… but I will need to sort that ending shot out… Maybe taking a screenshot into photoshop, or looping a  very small section, perhaps masking the original cycler out..
