Hey, I've recently shot some footage for my new short film against a green screen and took a whole bunch of stills on two different cameras.

The video footage is ok but the green screen is unevenly lit. And with the pictures i've took, although there good the green varies in shade and intensity depending on what camera took them.

I have AE 6.5 with keylight and numerous other keying stuff that i dont know how to use properly and every progam seems to work slightly differently. I just want an easy to luse program that i can learn and use with what i've shot.

I've been impressed with the chromanator stuff ive seen on this site and the great results it gets with the example bad screens are amazing. So I have high hopes.

What I was wondering is if Chromanator works with high res stills (2048x1536) ???? I cant seem to find whether it does...

Ok I deserve that smile

I've tried the demo though. and on new projects theres only pal and ntsc resoloutions ie 720x576 not the 2048x1536 of my stillls

And when i select the pal res and try and import a still noting happens!

So im guessing Chromanater cant work at anything higher then dv resoloution?

I have opened stills with no problems, but when I render I have to resize the image so it fits the blue line. My images are only 3.1 megapixels. Mabye you're pictures is biger.

Go to custom project and set up the project dimensions manually. You can enter the dimensions and other attributes yourself.

What kind of image is it? Chromanator can handle most fine.

When I import high res pics into chromanator, it will either go really slow or freeze. Evman101 said he had the same problem.

I was using a 2288x1712 pic.

unless CSB fixes it. You need to lower your picture res. before it will work right.

Chromanator is designed primarily to work with NTSC and PAL video. However, we'll see what we can do re: image support.

Hi - I've been playing around all night with keylight. Watching total training turorials and kinda got an alright key.

Loaded up chromanator - and changed the res to 1024x768 and imported a resized still. It worked.. I followed a simple tutorial.. and it worked again.

A faatastic Key.. wow!!! In under 10 mins.

But if im understanding things correctly. if i save that it will only save whats in the blue line??? ie the middle of the picture.. is that correct?

The blue line represents the borders of the frame, based on your project setup. So yes, it only renders what is inside the frame border.

See, you don't have to resize it.

ok now im confused sad

i manually made a new 1024x768 setting and resized my pic in photoshop to the same and imported it.

I keyed it. and zoomed out to take a look
and the blue bounding box isnt around the edge its in the middle of it.

So if i save it then i'm only saving the middle right? can i even save in the demo.? Im at work again now.. so i'll have to take another look tonight.

Thanks for all your help guys smile I really appreciate it
