Rendering Images With Transparency Support

[exood4studios]

I want to batch render an image sequence in maya and place it above a live action video footage. When I batch render the images into PSD (photoshop), the background of the 3D object is invisible (transparency=100%) and the 3D object is visible but when I take these images into a video editor (ULead Media Studio Pro 8.0), the "supposed to be" invisible (transparency=100%) background becomes black and the live action video footage behind the 3D image sequence is blocked.

What video editor supports transparency from PSD (photoshop) images?

By the way, I tried chroma keying but it didn't work well with half transparent objects.

get a comp application, because merging is more than jsut layering it on top its also toning and matching.

Anyway thing is transparency actually works black its just when you combine it with the alpha that it becomes transparent.

Yup I got it already. It was the alpha in the overlay options of the video. It should be alpha and not chroma. Anyway, thanks for the reply.
