Long exposure effect > light stripes
Hello,
I’m looking for a way to simulate long exposure time in order to create light stripes. Is there a way to accomplish this in after effects, preferably without the use of third-party plug-ins?

i assume you have footage that you want to treat… effects like echo, cc wide time and cc time blend can take frames from different times in the footage and composite them on the current frame, creating a long exposure sort of effect. echo may be the better of the bunch if you lights that you want to ‘streak’ since it has some blending mode settings like ‘add’ to help emphasize the light streaks.

I don’t have any footage, so everything has to be made from scratch. I was thinking in the direction of scripted movement of particle type things. Echo sounds like a good plan! I’ll give that a go. Thanks.

echo will work on a particle system, or any animated movement, but you will need to take you particle system or animated comp into another comp (called ‘nesting’ the comp) and apply the echo effect to the nested comp. otherwise you won’t see any effect.
however, you may want to try some other things first. try enabling motion blur for the layer(s) that you want to ‘streak’ and turn on motion blur for the preview (button at the bottom of the preview window that looks like a moving ball). you can intensify the blur amount in the composition settings by increasing the shutter angle.
you may find that some effects don’t work with ae’s native motion blur. for those you can apply cc force motion blur to the layer with the problematic effect. force motion blur has settings to increase the amount of ‘blur’ to try and achieve a more streak like look.
also since you are looking at particle systems, you may want to start with a long particle so it looks a bit like a streak already. most systems will allow you use a custom particle if the system does not have the particle you are looking for.

Thanks for the pointers, Kevin. I’ve already messed around with the motion blur settings but without satisfactory results. I’ll have a look at the other options you provided.

Perhaps precomping the footage, then duplicating the precomp. on the duplicate precomp set it to add, then apply echo and play with the levels to make only highlights get the echoed effect
