Does anyone please have any ideas on this as I am getting near deadline and still haven't found a method.
Thanks,

Mark Mapes Dec 17, 2013 9:59 AM (in response to 4500 Times)What are you trying to accomplish, specifically with regard to the white background on the first set of images? Do you want the white to be preserved in some way or eliminated? If you want it eliminated, then a keyer effect might be the answer.
A screenshot might help, including the Program Monitor and the Effect Controls Panel with the track item on the top layer selected.

3. Re: Premier Pro Blend mode issue
4500 Times Dec 18, 2013 1:02 AM (in response to Mark Mapes)Hi Mark.
What I have is an overlay image (or set of images) that has some scaffold on it. It has been rendered off from 3DS Max using a VRay material select render element so only the scaffold is visible but the remaining objects in the scene obscure the scaffold where applicable.
The scene image which scaffold will sit on top of has objects in around 3/4 of the scene with the white background showing to the side of these objects. The scaffold in the overlay images covers some of the scene objects and also some of the white background.
When I use a "Screen" Blend mode for the overlay images I get a pale partially transparent image of the scaffold where it sits above the scene objects and nothing at all where it sits above the white background.
The top image is the first frame showing scene objects. The second image is the scaffold overlay. The third image shows what happens when I use "Screen" Blend mode on the scaffold overlay in Premiere Pro. The scene object images are on Video 1 and the scaffold images are in Video 2.
The result I desire is the top image (scene objects) with the scaffold added on top.
Hope this helps.
Thanks,
Terry

Fuzzy Barsik Dec 18, 2013 4:55 AM (in response to 4500 Times)1. Check this help section on how blending modes work.
2. You can either apply Luma Key onto your 'scaffold' track and set Threshold and Cutoff to e.g. 15% or experiment with procedural mattes.
3. You really want to re-render your scaffold with aplha instead of black background.

4500 Times Dec 18, 2013 5:53 AM (in response to Fuzzy Barsik)Thanks for that.
I am fairly new to this so forgive my ignorace.
If I render to say a TGA with alpha channel, which mode do I then use to blend the scene frames and the scaffold TGA's?
I did try rendering to TGA the other day but did not get the desired result.
Thanks,
Terry

Fuzzy Barsik Dec 18, 2013 8:32 AM (in response to 4500 Times)If you render your scaffold with alpha, black background turns into transparent area, hence you won't need to utilise blending modes, you simply overlay the scaffold and track below is seen through transparent area.
If you have some issues with rendering with alpha, that's another story. As Rick Gerard asked you, upload a sample file and post a screenshot with your rendering settings.
