I've been asked to recreate a Cellphone HUD while someone is using it.
The original footage is too much bright and poor done to show what there actually is on the REAL one.. So I started thinking about it. Forgetting for the moment about the tracking, do you have any suggestion?

Actually, recostructing it is ok, but then I came to the problem of making it FEEL real. In the clip there are rays of light and reflections, and it's not something I can manage playing with opacity of blending modes, even layer modes don't apply here. I played around with some ideas that came to nothing until I tried to duplicate the old screen over the new text and things began to go right.. But I'm not sure of it.

I've uploaded the frames here: 2923_comp.zip

Sorry for the password, but it's "sole".
Any idea of "how to" achieve a better result?

Once you nail the perspective down, I think you've got it!

First I would tweak the icons/text to make it look more realistic. Noow it looks pasted on and one reason is that the icons do not fit perfectly on a grid in that perspective. That type of screen has icons and text created by blocks on a grid- so everything is parallel or perpendicular, icons fit in boxes, and squares are exactly the same.
So, your battery icon should be perfectly aligned on a vertical and the same width with the thickest part of the icon above and parallel and the same height with the antenna icon to the left. Of course that all gets distorted on the projection to match the perspective of the screen but the proportions stay the same.
Second, the edges are way to sharp- you need to replicate the softness of the edge from your footage.
Third, the level of gray is still too dark, it stands out.
Fourth, if my memory serves me right, on that type of display you would get a small soft shadow at that perspective under the text/icons on the screen- this one I can't verify since I do not have any screens of this type around me to take a look.
Hope this helps.

You would receive more assistance if you uploaded the image/video directly to the COW.
