The Flash effect
Hi,
I am wondering the most effective way to create the “Flash” effect where someone moves thru a shot and it is then sped up (I have no problem with the speeding up element) but leaves a streak behind…..
I want to know how to create that streak with in after effects… yes… i know it is like a motion blur but to leave a longer trail, what is involved?
Cheers
Brad

Which method will work best depends on the footage and how extreme of an effect is desired and it sometimes takes a combination of all of them to get the desired effect:
1. Max out the motion blur settings in the comp settings (keep in mind that a layer has to move in order for motion blur to have any effect) and sometimes render, re-import and add additional blurs.
2. Use a duplicate layer of the footage on top of the main layer and use a directional blur, some other smear effect or a combination of several.
3. Use a “motion trails” plugin like the one in the BCC set
Depending on the details of the footage and desired effect (whether the trails/blur should be on just the subject moving through the frame or the entire frame), more advanced techniques rotoscoping and keying may be necessary in combination with the methods above.
