Hi,
I'm looking through the manual and can't seem to find the tools to allow me to repostion the greenscreen plate. I want to resize and move it to the lower left of the background plate, is there a button to allow this to happan? May seem really obvious but im still getting to grips with the demo.

If I understand you correctly, then yes, there is a feature that allows you to do this. You do this in a very similar way to using the "key" feature of a Chromanator, in that you need to go into "Object" mode. Once there, look to the top right of the program, in your "Tool Box".

You should see "key" and to the right you should see an "Animate" tab. After selecting animate you should see all the necessary controls to animate your green screen plate in the "Tool Inspector". I hope that works out for you.

Edit/Note: More details pertaining to the features of animation mode can be found in the extended, more in depth manual that accompanies your Chromanator download. Refer to pages 46 through 49.

Have fun.
Wizard.

Wow it worked really great, thanks man. I'm pretty much there now with the program and now seriously thinking of buying it. I still have the problem of the green reflecting on parts of the model, as parts of it are chrome it is impossible to stop this, do i use a garbage matt to stop it keying certain parts? most of it is fine, but a few small spots show right through.

You are welcome, glad it worked out for you. I would certainly suggest purchasing Chromanator. Personally, I feel it is a good purchase if you plan on using a green screen often. It is even useful for just the occasional green screening need, and holds the possibility of many other graphics as well.

The chrome model reflecting the green is definitely a difficult challenge to over come. I have never had to deal with such a problem, so I can not make any suggestions. I hope a solution presents its self.

Have a great day/night.

Okay no worries, if anyone out there has a knowledge of somehow keying bits of greenscreen background so they are not removed.

Example: A car with chrome wheels set up with green screen background but the green reflecys onto the wheels. i want to some how keep the chrome wheels, is there a way of masking/garbage matting? so i can keep these wheels.

Help me please.

Cheers

I ha this problem once with a chrome table. I can't remember how i did it though. I think it had something to do with spill supression. See if that gets rid of it.

You can draw a Garbage Matte (referred to as "mask" also) and change its setting from instead of making the object transparent, make it opaque. That way you can just put the matte over the chrome parts of the wheels and just move it every few frames (Chromanator will automatically create an equal rate of change between two points if something changes between both points).

Here's a short tutorial I made.

FIRST THINGS FIRST - Go into Object Mode (with the object of choice selected).


Now, we go into Garbage Matte mode (right next to Key mode) and press the + sign to add a new mask.


Good, our new mask has been identified and is ready to draw. Notice how it is in Draw mode. We'll go back to that later.


Here's a photo from my first test involving a toy car and horrible lighting. I just pointed out a few of the spots where the car was either transparent or chrome and Chromanator keyed out. I will only be showing how to prevent the keying out of the wheel in this tutorial.


Click on a spot in the wheel to start drawing a mask. An 8-shaped point, indicating the first point, will be drawn. The rest will be diamond-shaped. You simply need to click - no holding and dragging is needed (unless that makes it easier for you. Just click and it will automatically connect the previous point to next one you draw.


You're almost done drawing the mask - but it's not closed yet. It's not effective until it's closed (for obvious reasons).


You can draw a stray point and just drag it over the 8-shaped point to connect it. You will know for sure that it's connected when a partially transparent light blue color fills the now completed shape.


OPTIONAL: You can use the Smooth Points slider to, well, smoothen up your points. It's possible to make a diamond shape and use the smooth point option to make a diamond into a circle, but that's different. Here, the car is at an angle, therefore we need to draw it on our own.


Now click on the animate tab. Notice how the light blue overlap changes to red. It's ready for action (NOTE that ALL masks are not functional until switched to animate mode!!!!!). Take a look at the tab that says "Transparent Matte". This means that anything under the mask will become transparent. We don't want that - we want the opposite.


Click on the little tab next to Transparent Matte. It will open a tiny little bar with the two options. Click Opaque Matte.


All right! That's all there is to it. Now let's take a look at the difference between the wheel -

BEFORE


AFTER


Much better! Now you can apply this to anything.

Hope this helps!

Spill Supression w/o the Extended function on seems to change people's color and using the Hue function (Warning: will also change the color of your green/bluescreen) will dramatically change the color. It's time for me to go to bed now, so I won't ramble on about that.

Ok im looking around on the net and i cant find any straight answers on scaling in green screen. Have i got this right: Background plate with object 150 Meters distance from camera, to get the green screen object looking right do i divide the distance by 16 if the model is a 1/16th scale. so there fore place the camera 9.3 meters away from model? I know you can scale in chromanator but i wanted to get the models as close to perfect res as i can. and get all the angles looking right. am i making sense? I need them to look as real as i can.
