  Exporting flv or mov with transparency

  Posted by Ross Kidd on September 4, 2008 at 8:35 am

  I have need to export my flv with a transparent background. I have

  format: Adobe Flash video
  post render action:none;
  channels: RGB+alpha
  depth: millions
  color: premultiplied.

  When I import to flash it still has the back background. In my comp the transparency button is pressed so it looks how I want it to look in flash.

  Any suggestions much appreciated.

  Have you tried re-importing the flv back into AE to see if the programme registers the alpha channel? If you can toggle the chequered background on and off in the usual way you’ll know that the alpha channel is there. I am not entirely familiar with how flash players interpret transparency, but maybe they just show it as black.
