Hi! I purchased this video pack-1 and am having trouble imbedding the video as an mp4 and webm file into my web page. I would like to create an overlay on my landing page, but I am losing the alpha channel. I exported it as a .mov from AfterEffects using the lossless with alpha format, but when I convert it from a .mov to a .mp4 I think I am losing the transparency. Is there any chance you could provide me with .mp4 and .webm files with the alpha channel? If so that would be such a huge help! Thanks for creating this animation, and I would be happy to send you a link of my web site when it is completed. Thanks! Donna

Or you can use a mask (matte). It’s not difficult. You need to do a fill with white and render in any format. If you want I can make a mask for you. Please contact me through my profile page, then we will be able to communicate via email.

Flash supports the format of PNG, which has its own 8-bit alpha channel. Transparent background in a SWF file:
