    Alpha channel video makes for a larger-than-target bitrate flv


      I'm looking for some information regarding the final bitrate of alpha channel encoded video. We are producing transparent flvs. When targeting a number, say 200kbps, in Adobe Media Encoder, the final encoded flvs has a bitrate of sometimes as high as 350kbps or 400kbps. And that's just the video.

      When I encode without the alpha channel with final flv video bitrate is basically exactly what I targeted.

      I'm assuming GSpot and MediaInfo to look at the final flvs.

      Why doesn't Media Encoder produce and flv at the target bitrate? Why the higher bitrate? Is there a way to set the final target for an flv? Is there better software?
