Colour key and hair Preserve Transparency ?

[Michael Szalapski]

Key the hair seperate from the rest of the shot, using garbage masks to seperate the different elements.

L’OREAL Paris makes some fine conditioners, I know some who swear by Pantene PRO-V, I would suggest you try several different ones and find the conditioner that works best for you.

In AE you can use one of the colour channels as your alpha channel if you want, there are several ways you could accomplish this. Effect>Channel>Shift Channels is one way, or you could do Effect>Channel>Set Matte, there are other ways.

You could use a layer as a track matte to fake a preserve transparency effect.

Cows are evil.

There, I think I answered all of your questions. Out of curiosity why are you not using keylight? It rocks.

Thanks for the hair tip…
I just used Keylight. It is totaly cool. Two clicks of the mouse and the job is almost done 🙂
I will have to play around with channel shifting and channels in general in AE.
Inceed cows are truly evil.
Thanks again

The little T checkbox next to the layer’s blending mode will also preserve transparency of the layer(s) beneath when it is applied.

The cows are looking at you because they are jealous of your hair conditioner. But not for long. Soon they will have all the conditioner they want.

Oh yes.

You would be staring at everyone else too if everybody wanted to make hamburgers out you.

That and cows are evil……..

No it is only me that they stare at. They seem to be saying “come and join us”

The preserve transparency button does not seem to work the same way as the
lock transparency in Photoshop. In Ps you can lock it and paint and it over it and it does not hold the stroke or effect.
I will have to experiment
Ta again

Hi Trug,

I noticed that approximately a month ago you posted a question regarding the cogs tutorial I wrote. If you email me directly- chris@chriszwar.com I’d be happy to elaborate on a few details- I wasn’t able to reply back then.

In regards to keying, I suggest registering at DV garage (dvgarage.com), which has many free tutorials including some on keying- they demonstrate breaking up a video into different parts to use different key settings. The keying tutorials are part of their light-sabre series. One of the tutorials deals specifically with the DV Garage keying plug-in, which they sell, but the principals are the same for keylight.

I love Keylight and think it’s brilliant, however I don’t like the way it tries to key and colour correct at the same time. I use Keylight to pull a key, then use the result as an alpha-matte for a duplicate of the original footage- and then I use the normal colour correction tools (spill supressor, HSL & Levels) to manually colour correct the original layer.
