Hi,

 

Rendering from After Effects to play in Powerpoint 2007 and am not seeing a transparent background in the video. I've tried the combos below and included a snapshot of the render queue:

 

Which (if any) of the combinations should have produced video with a transparent background? Are there additional values for rendering that I need to change; if so, what are they and what should they be changed to?

 

(Additional info:

- This project was imported from Illustrator (Document profile = Video and Film)

- Applications:  After Effects, Illustrator (both CS5)

 

System spec

Video information: NVIDIA, GeForce GTX 480, driver ver 8.17.12.9573

Prod Name: After Effects CS5

Prod Ver: 10.0.2.4

OS: Windows 7, Ver: 64-bit

DirX: 11

Processor: Intel(R) Core(TM) i7 CPU

Memory: 6.00 GB)

    PowerPoint doesn't handle transparent video and that's the long and short of it. The only transparency format it supports are PNG images. Everything else will have to be done by baking the background into the video.

    For my own education please confirm if my understanding is correct........

    Even though Powerpoint documentation states that it supports .avi and .mov file types which support transparency (Channels - RGB+Alpha, Depth - Millions of Colors) it supports playing those types of video files but not the transparency functionality.

    No version of PP I know has ever supported transparency in videos. All it does is borrow system components from Quicktime and Flash to dispaly such files, but it doesn't see the transparency to render it to its desktop composition. That's the long and short of it.
