Hi here are a couple tips in case you are not doing this already. Hold down option to offset your tracker when you need to.
If a foreground element completely blocks you subject (so that there is nothing to ‘offset track’), then skip forward to the first frame where your subject is visible again. The inbetween frames will be interpolated. People who cross in front of your subject should be on their own black mask layer.
Good Luck

Hi, here are a few tips. Make a 32 bit project. Working Space:None. Enable linear blending. Set the initial LOG to LIN converter on your cineon sequence to have a highlight rolloff of 0 (not 20 which is the default). Otherwise the whites get clipped at 1. Bring all you elements together inside a linear comp. Once you are ready to render, drag that comp onto the make new comp button and apply a LIN to LOG instance of the cineon converter effect.
In this way you can roundtrip cineons with absolutely no shifted pixels.
In my opinion you should avoid using a color management workflow with cineons (At least I can’t get it to work losslessly).Good Luck

I also heard about this other company that did some VFX stuff in “Stranger than Fiction” also comped in AE apparently:

Hi Adolfo, thanks, I guess I’ll have to figure out what film stock my cineons are. That’s a big new feature that hasn’t been mentioned much.
Thanks

Hola Adolfo, I think my problem stems from the fact that the cineon ‘more options’ dialog is grayed out in CS3 (in AE 7 it works fine). So I can’t linearize the cineons as I would like to in CS3. Here is a cineon if anyone wants to try.

If anyone knows of a workaround, please let me know.
Thanks Pete -
Hi, thanks for the links. Stu Maschwitz’s linear workflow works well in AE 7 but I was trying to workout a simpler way to reach the same result. In CS3 the ‘more options’ dialog for cineons in interpret footage is grayed out for some reason, so I can’t get it to work there anyway.
The middle image of my previous post sort of mimics his linear work flow, I just use a couple instances of the exposure effect instead.
Thanks

Hi, the error message still comes up if I type in .value. The expression seems to work if I just click OK and ignore it though.
Thanks

Hi wuzelwazel, the linear profiles don’t seem to work better in that regard. Here is a screen shot to show what I am going for.

The middle image is the one I am trying to get (which I created with an HDR image by bracketing my blur with the exposure effect set to a 1/2.5 gamma and then the exposure effect again as an adjustment layer with a 2.5 gamma to negate the original gamma. This seems to mimic the gamma 1.0 blending almost perfectly for crossfades and other instances when 2 layer interact, but don’t seem to work for invividual layers whose pixels are being filtered through an effect (eg. blur)

Hi wuzelwazel. Thanks for the info that’s great if CS3 can do that. I don’t actually need it for the lensblur effect. I want to be able to plug a depthmap (or any black and white image) into any property of any effect like say turbulence, so that the intensity of the turbulence is governed by the black and white image.
