Hi Blaise, Thanks for the reply. Yes that is understood but I’ve said repeatedly that workflow (“the cleanest method: you refer to) will not work for me due to being too time-consuming having 3000 dots to animate. It’s just not going to happen in the time available.
I am seeking other workflows which will cut down on that time. I’ve had some success with keying, but there is some blue in the rest of the video, so I get some ghosting from the additional blues throughout the image, which is not ideal. Perhaps there is no way around this but I thought it was worth asking anyway! -
Hmmm, there are over 3000 dots and I don’t have the time to use this technique on them individually. The positioning isn’t a problem. I have been playing with keying though and have found I can key out the blue then invert it. Now I just need to figure out the best way to re-colour the dots to 100% opacity red. I think what I need to figure out how to do now is:
use the black pixels (created during keying = the background image) to create a mask of the dots
make what was the blue dots transparent
put a red solid layer underneath
but then how would I get the non-red pixels to be transparent when I export from AE?Maybe there’s a better way? I’m also playing with the shift channels effect atm, after ruling out a few of the other Keying effects (extract, difference etc) to see if I can simply extract the blue in the video.

Hey John – sorry if the description was confusing. That is the video I’m working with so yes it does have dots, but basically I want is to separate these exact dots from the background footage. The end result will be a video with the dots only, and a transparent background, no background footage. I’m hoping to find a workflow that saves me from re-animating the dots individually as this will take a long time. Any suggestions appreciated!

Hi Dave, Thanks again. You’ll have to trust me I know what I’m doing with the specs – I’m not really wanting to go into that side of things here as it is convoluted.
Thanks for the suggestion re animation: Happily I am capable of doing that process, however with the number of dots it would still take me about 100 hours – so I’m looking for workflows that may, for example enable me to pull out all the blue and dispose of the rest so only the dots remain, rather than re-animating each dot – any ideas? -
Thanks Dave. Yes good point, I’ll go with pngs.
I am working at 30fps at the moment – all other footage and sequence settings are that framerate – the export settings will be determined by the exhibition specs. -
Security settings changed – thanks for letting me know!

It turned out to be a dual problem. The length was due to Quicktime player not reading the file correctly and just adding hours of length, and so not even a compression issue. Other players had the correct length. The quality issue was indeed a frame rate conversion that I hadn’t noticed. Big thanks for putting me onto that track!
