import video with alpha background
I have shot our learning host on green screen, keyed out the background in adobe premier cc and rendered a Quicktime file that imports into all my other apps with the alpha or transparent background...
Hi Mohammed,
Alpha channel transparency isn't supported in HTML5 output, so FLV videos with alpha channels will be encoded as MP4 videos in HTML5 output.
Have you tried publishing with Flash-first to see if that makes a difference? The video won't be encoded to MP4 in Flash.
