Don't use pix_alpha, but put colorRGB and alpha objects at the end of the chain. The last inlet to colorRGB is the alpha of the object from 0-1.

I forgot to mention that i use pix_texture2 and rectangle to show the pic.
never mind
Do you mean i have to put rectangle, then colorRGB and alpha (being these 2 the last objects on the chain?
no. as you might have noticed, in Gem basic modifiers (like [rotate], [color] or [alpha]) apply to all openGL-objects ("Geos", like [rectangle] or [sphere]) that are "below" them. thus "colorRGB and alpha (being these 2 the last objects on the chain)" will have no effect at all. it should look like
[pix_film superdooper.avi] | [pix_texture2] | [colorRGB] | [alpha] | [rectangle 4 3]
the last inlet of [colorRGB] is for alpha (as ben has already said) and sets the colour for the rectangle (this has nothing to do with the texture-data). Since this can be done by hw-accelerated gfx-cards, it might be very fast (setting the alpha-channel of the image-data would be slow) [alpha] enables alpha-blending (otherwise the alpha-channel would be ignored)
