Venetian Blinds Effect/Transition used on NBC branding

[David Bode]

Or or something like this…

target = thisComp.layer(“GRAD”);
red = target.sampleImage([80, 200],[3.5, 3.5])[0];
green = target.sampleImage([80, 200],[3.5, 3.5])[1]
linear (red, 0, 1, transform.yRotation, 120);
linear (green, 0, 1, transform.yRotation, 240);

I have a layer “GRAD” with a black solid as the base. Then I animate a red solid across so now the layer is filled with red. Then I animate a layer of green across so the layer is filled with green.

This expression doesn’t seem to work for the red gradient, but it does work for the green. If I delete the 2 lines that index the green channel it works, but I want both to work.

I believe that my sampleImage only looked at an image’s RGB luminance value without having to dive into the individual RGB channels.

BTW, the reason why the Red Channel doesn’t work is because it is being overridden by the Green Channel as per how your script is written. Your two linear Expression methods work similarly, but the second one will override the first. Hope this makes sense.

I think I have it worked out now. Check it out.

I worked out a different way to get them to spin how I wanted. It probably is not the most elegant but I can make the triangles spin to the right, to the left, and just make half of them spin left and half right from the same gradient layer.

I think this looks pretty hot now.

Thanks for your help!

That looks very nice Dave! If you don’t mind sending me the AEP, my email is rork_AT_broadcastgems_DOT_com

I’ve got a couple of ideas to add into the mix.

Hey Dave,

Is there any way i could get a copy of your AE project file for this Vimeo version of the venetian blinds? It turned out great and I really want to get in their and dissect it!

Great job!

Hi David,

I love this effect you’ve put together. I do photo-videos for family and freinds and I was hoping you could send me a copy of this AEP so I could use it on some photos and see how it is put together.

My email is gdefrates@aol.com.

Thanks, David.

Hi David,
Can you please give me a hint as to how you solved the “bleed” problem? The vertical tiles look like they lock perfectly into place when I keyframe through the comp, but when played out I get the bleed through you mentioned. Any help would be great. Awesome comp, by the way.
Many thanks,
Kelly

I placed a set of triangles inside of the source comps, made them black, and scaled them to 98%. In the final comp with the camera I made an adjustment layer to control opacity that I linked to the adjustment layers in the source comp A and B and keyframed their opacity out every time side C was on. For what ever reason the side on 240 degrees had a bleed that I could not fix.

I made a tutorial on this that should be on AEtutsplus.com some time this week.

Beautiful stuff Dave! I’ve been looking for something like this for a while now although I’m not on the level of you and Roland. I’ll be looking for the tut on AEtuts. Thanks again!
