This addon lets you create a long exposure effect in Blende Video Sequence Editor. The workflow is the same as descirbed in Aidin Robbins' LONG EXPOSURE Video Effect video.

1. Download the long_expo_effect.py file
2. In Blender go to Edit -> Preferences -> Add-ons ->Install
3. Select the downloaded file

1. Select a video strip
2. Open up the Strip Panel
3. Search for Long Exposure Effect panel
4. Click one of the buttons
5. Change the properties on the redo panel

• Levels: The number of duplicated strips, the higher the value the more you can see the effect. But it can slow down your scene significantly. (I recommend to set it to ~40-50)
• Opacity: Opacity of the duplicated layers (you should keep it around 0.05)
• Fade In / Fade Out: Start/End the effect gradually. If they are unchecked the beginning/end will be cut off
• Comet Mode: Gradually decreases the opacity of the layers.

To improve playback performance in the Preview window got to View -> View Settings -> Proxy render Size -> Set it to 25%
