<p>Is there a way in post to simulate the effect of a slow shutterspeed shot that leaves trails behind bright things in the shot that are moving. I was thinking if I recorded something at a high frame rate then used some sort of compositing filter that multiplies the frames that might do it. I feel like that would also cause darker things in the frame to also come out blurry or leave trails. Here's an example of what I'm trying to reproduce with a sparkler from a pit bull video <a href="https://youtu.be/bTXJQ5ql5Fw?t=4m12s" rel="nofollow">example</a></p>

Try the [Echo](https://helpx.adobe.com/after-effects/using/time-effects.html#echo_effect) effect. To avoid echoing the darker portions, duplicate the source and apply the echo to it; experiment with the compositing modes and also layer opacity.
