Ya, Darby’s suggestion is better since mine involves a bunch of variations of the expression. If you did use my version though, you would want to use hold keyframes on the slider so that it just jumps to the next number.

No, just put the expression I wrote in the opacity property of each image. You will have to change one detail of each images expression though. So in the first image, it will say x==1 (the one I actually wrote), in the second, change it to x==2, and the third x==3. When you do this, your just telling it that when the slider is on that number, to show the image, if it’s not, then don’t. For this to work the way I’ve written it, the slider should be on a null object called Null 1

I’m sure Dan is right about the expression. But what if you precomposed it, duplicated it, scaled one down, and then generated a stroke on the smaller precomp so that it matched the sizing of the other? Might not be perfect, but could potentially work.

I think I understand what you’re trying to do. Maybe you could use something like this to create it?

Just do it with opacity. So lets say you have 5 images you want to choose between. You would just write an expression that says, when slider is 1, have opacity at 100 otherwise at 0. For the second image, it would just be, when slider is at 2, 100 otherwise 0. I’ve done the first one for you below. (I put the slider on a null object). Simply change the “1” after x== to “2” for the next layer and so on.
x=thisComp.layer("Null 1").effect("Slider Control")("Slider");
on=100;
off=0;
if (x==1) on else off“|_ (°_0) _|”

It pretty much just requires a laptop, a little software and two pieces you may need to buy or rent.
I would just get some kind of firewire or usb camera switcher, run all cameras into that, and then use a regular mixer for audio setup and run a single xlr out into something like an m-box or other audio interface. That way, you have a single video and a single audio feed in your computer that you can run into the wirecast cast software. You can just do your switching manually. You can use livestream or justin.tv or something of the sort for the streaming. Free or paid based on budget.
Simple one or two man production that’s super cheap.

Ok, gotchya. There is probably a better way, but this will work.
-Take your text layer, right click, and convert to shapes.
-Open up the shape layer and go to the transform>opacity section of each letter, set it to 50, and enter the expression below. (not the one where I explain things, obviously)Here is how to alter it for different results
on=100;
off=0;
x=wiggle(10,50); – Change the 10 to a larger number for faster blinking, or lower for slower
r=random(9);
if (time<5+(r*.1)){ – Change the 5 to the second you want the effect to stop, in this case the effect ends 5 seconds into the timeline. The (r*.1) is an additional parameter to make them stop at different points. So this equation is saying stop at 5 seconds plus a random number (1-9) *.1 -So each one will stop at 5.3 or 5.7 or 5.2 – whatever it generates. If you would like there to be a longer gap between each one stopping, simple make the .1 a larger number. The larger you go, the longer it can wait to stop the effect
if (x>50) on else off}
else onThe reason this approach sucks is because you have to manually enter it for each letter and if you want to change it, you have to change each expression, rather than just one. But it will do the trick. And if you do need to alter them all, just press “e” with the layer selected and it will bring up all of the expressions.
on=100;
off=0;
x=wiggle(10,50);
r=random(9);
if (time<5+(r*.1)){
if (x>50) on else off}
else on“|_ (°_0) _|”

In order to change how frequently it shuts on and off, just change the first wiggle value. The bigger that number, the faster it should flicker.
Set your opacity to 50 then put this expression in it:on=100;
off=0;
x=wiggle(10,50)
if (x>50) on else off“|_ (°_0) _|”

I’m guessing that you may have moved the file from its original location or renamed it or something. It may be displaying it when you aren’t ram previewing it because it was stored in memory, but when you go to preview it and it tries to render, it’s like, “hey, what? Why are you telling me to render something when I don’t know where it is. I’m gunna make you look at these pretty colors I can make instead.”
Again, just a guess.

Since your production needs don’t sound like they’re particularly cinematic, I would recommend using Kinoflo Diva lights. They’re low energy consumption fluorescent lights that are dimmable and create a nice soft light. You could probably get a fair amount of them in the space without upping the electricity too much, which is expensive. They’re also light weight/portable.
Without knowing exactly your shooting format, I imagine you would want to create what we used to call a “ring of fire.” This is where you basically take a bunch of soft lights and make a u shape around the subject. This way you just have a nice even soft light around everything; good even lighting, like a sit-com. Then you’ll probably want to hit the subject with a back light.
It sounds like your set will be relatively static, so you might want to build a pipe grid so your lights aren’t in the way and can jump them around in case you want to highlight other parts of the set. Make sure you have enough electrical outlets in the top of the pipe grid so you can easily plug in your lights no matter where they hang.
Think about sound too, if you’re in a big space, it’ll sound like that. The best sound proofing is a box in a box. So, you put up walls, then build more walls inside that and insulate the space between. You’ll also probably want cloth or something of the sort on the inside walls to dampen the sound.
I know that barely scratches the surface, but hopefully thats something to start off with.
