 Bar Transition in After Effects on Jun 17, 2016 at 5:12:12 pm

In my many forays through YouTube Tutorials on After Effects, at one point I came across a transition that was kind of like Venetian Blinds but it was more like 10 or 15 columns of video rotating onto the screen. Its a much cooler effect than plain Venetian Blinds. WOUld anybody know what this transition effect is called?
Thanks Richard Hutt

Can you post a link to one of these videos, please. It would make it easier to understand what you are trying to accomplish.

Hey Johnny, thats the problem, I haven't been able to find one of these videos yet. It was probably a year or so ago that I saw it. Ive had a couple of other people reply, one with a walk through and one with a name of an effect tottery. Thank you so much for replying to this. I do appreciate it. Im gonna keep looking for the answer.

Without seeing it I can only guess. I've used a transition before that sounds like what you're talking about. Here's how I do it.

1. Check the 3D layer box on the two video layers you want to transition between
2. Make a 3D null and push it back in z-space to half of the comp width (960 for full HD comps)
3. Parent the first layer to the null and set a key for Y rotation
4. Move down the timeline and rotate the null 90°
5. Parent the second layer to the null, now you should have a transition between them
6. Make a new comp the same size as your main comp
7. Make a gradient and use mosaic, or use different rectangles (or venetian blinds) to make a matte using only grey tones—this tutorial might help:

The intro to the tutorial uses a similar technique.
8. Put that comp into your main comp and turn off it's visibility
9. Set up time displacement on a new adjustment layer and set the Time Displacement Layer to your matte
10. Tweak to taste
