The script I wrote doesn’t necessarily have to be used on the green screen. It can be used on any part that is pretty consistent throughout the shot, but does have the flickering. You could even use the motion tracker to track the point of the color sampler to an object that is moving. You might also need to adjust the sample radius as well. I tested it out and it worked perfectly for me (brightness was not stuck at 100).
It should be ok if the background flickers after you remove the flicker from the actor, since the background will be keyed out anyways. You will have to adjust the key so it also keys out the brighter frames.

I just came up with this expression that might work for you:
- Add a Brightness & Contrast Effect to your footage
- Add a Point Control to your footage
- Add a Slider Control to your footage
Drag the point of the point control to a good consistent part of the green screen where there are no shadows or moving areas.
Move your mouse over the green screen for that point and look in the info panel to see the green color of it. I’m guessing it will be somewhere around 116 (depending on how you lit your screen)?
Now adjust the slider control to equal that number. (You may want to tweak this a little later)
Then apply this expression to the brightness control:
NormalGreen = effect("Slider Control")("Slider");
samplePoint = effect("Point Control")("Point");
sampleRadius = [5,5];
sampledColor_8bpc = 255 * sampleImage(samplePoint, sampleRadius);
(sampledColor_8bpc[1]-NormalGreen)*-1;Jon Geddes

Yes, but there is no simple checkbox to do it. You must edit the menu in Photoshop.
- Locate the layer group for the button (or create one if there isn’t one using the (+) prefix)
- Create a new layer and give it a name with a prefix of (=1)
- Select the area for the underline using the selection tool
- Use the paint bucket to fill in the selected area
- You can modify the color of the highlight in Encore by editing the menu color set

The particles can actually be created using CC Particle World, and the reveal of the text is done with a simple Linear Wipe.
I used both of these effects for our Enchanted Waters Motion Menu:

Watch the “Afterista” Tutorials that will show you how to do the write-on text:
https://library.creativecow.net/search.php?q=afterista
Then apply the CC Ball Action to it (set scatter to 0, and adjust grid spacing)
Create a new solid and place it below the text layer, then apply a ramp or gradient to it for color
Set the track matte of the color layer to luma matte of the text layer (or alpha matte, depending on the look you want)
Precompose and apply glow effects, etc.

[Todd Kopriva] “Anyone who knows wouldn’t be saying, so I can guarantee that anyone who told you this doesn’t know.”
It was from someone who has been doing beta testing of previous versions. But the fact you are disputing it, gives me hope. I don’t really care if they were wrong, all I want is 64 bit support.
I’m sure there are all kinds of NDA’s, so I respect the fact that you cannot disclose this information.

I used this expression for our Opening Night Motion Menu Kit, which features a theater with realistic lighting:

Name your null object “Flare_Source”, make sure 3D is enabled for it.
Now after you apply the flare effect to a new layer, set the flare source to an expression:
thisComp.layer("Flare_Source").toComp([0,0,0]);Jon Geddes

You are encountering the limitations of a 32-bit application which uses layer based compositing. You either have to reduce your images to an even smaller resolution, or use a node based compositor, or wait until Adobe finally releases a 64-bit version of AE, which unfortunately I heard won’t be happening for CS5. I hope I heard wrong.

The mpeg compression is not the issue. It is definitely the downscaling. Straight SD to SD does not show the aliasing. Only HD to SD.

Yes, you would think the poor quality was the result of incorrect field dominance, but I assure you it was not. There was no deinterlacing or reversal of fields. Footage is kept at Upper Field First throughout the process. Quality is at 7 Mbit CBR or VBR 2-pass (same aliasing problems).
The images in the article were cropped so you can see what it looks like at 100%.
If you’d like, I can process a 5 second sample clip of yours using the method in the article and you can compare. You can even send me a clip that has difficult titles (script fonts with thin lines) and I can show you what SD footage is capable of looking like.
