simple question: belief how to make a crowd (I dont get it…)

[Jeff Memmer]

It sounds like you need to also view this video from them, titled “Behind the Green Screen,” where they briefly tell you all the plug-ins they use, and how they managed to build the composite with a very tight budget over a 2 month period…

Hi jeff

I aprreciate your post
but I did watch that video, and I know they use particular
and when you read carefully, I ask technical question regarding one of may steps in the
how to make a crowd video, which I missed and I dont get it until now how to do that step
1. how to crash color to remove bad key, etc?
2. regarding gradient at the legs
3. regarding the transparancy in quicktime

anyone?
thanks

Crushing the blacks refers to making the blacks, SUPERBLACK.

Take some video footage and apply a levels effect to it. Take the video imput slider for black and move it to say 50. That would be crushing the blacks. If you look you can adjust both the RGB or Alpha channel. They adjusted the alpha channel, and made the blacks superblack. This affects the video levels, but gives them a cleaner key. You can see when they crush the blacks, how the video level comes down, in the video.

The gradiet fill is achieved by creating a ramp. Create a solid, add the ramp effect, then lay it over your video. You can use the siloutte luma transfer mode, or the luma track mode of the video layer. Will give that soft edge.

Afterwards, they rendered it out with a alpha channel.

The elements have alpha’s, that how transparents are created.

Hi Thanks John

oh thats level effect
why they use a layer? is that a displacement layer?
I wonder why not using the effect to that specific crowd movie? oh is that because they have 2 layers ? so its easier to get displacement?
thanks again

I believe they used an adjustment layer, then a layer for the ramp. The adjustment layer effects everything below it. So I think you are right, they put the levels effect on there, since they were looping the video, this way they only had to do the effect once, rather then twice.

Well, if you are in doubt about how to use the ramp to create that opacity gradient, just create a big mask and feather its edge. You ‘ll have the same result. About the Quicktime transparency, other people have already answered it, but another way you can achieve this effect, is not to render the comp, just drag it to the next comp and it will be automaticly transparent (but it can increase render time).

Maybe these tips sound dumb for many advanced users, but remember something very important. No matter the way you do it, if the final result is what you need, it’s OK. There are different ways to achieve the same effect.

I hope it helps.

Hi Reloaded

thanks for the tips
So I assume if we in a big projects, rander each of the composition first would decrease the final rander time later?

I totally agree with you the final result that matters 🙂
thanks

[cicit] “So I assume if we in a big projects, rander each of the composition first would decrease the final rander time later?”

Yes. But! If you are really dealing with a big project I would also advise you to work with proxies as much as you can as pre-rendering 20 or more comps can lead you to a mess especially when the client or even yourself want to alter things, like timing etc…

Salut.
