  Rendering from A E to play in Powerpoint 2007 and am not seeing a transparent background

  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)

  Combinations
  1.Format – AVI
  Video Codec – None
  Channels – RGB+Alpha
  Depth – Millions of Colors+
  Color – Straight
  Comp background is black
  Transparency grid is on

  2.
  Format – AVI
  Video Codec – None
  Channels – RGB+Alpha
  Depth – Millions of Colors+
  Color – Premultiplied
  Comp background is black
  Transparency grid is on

  3.Format – Quick Time

  I could be wrong but I am fairly sure powerpoint doesnt do alpha channels.

  The higher they fly… the much.

  I know that powerpoint supports alphas in PNG stills, so maybe try a png sequence?

  Powerpoint supports .avi and .mov file types.

  The only thing I could think of that might support transparency in a moving image in Powerpoint would be a GIF
