    After Effects + Adobe Media Encoder + Flash = Most Random File Sizes Ever

    zumajoe

      Asking this question in this AE forum because I think more would have knowledge on the topic here than the Flash Forum. 

       

      I've heard that video compression is more of an art than a science...  Could someone provide me some insight on the following?

       

      -Created a 12 second, 30 FPS, 300x250 banner animation inside of After Effects

      -Exported for FLV/Flash to be placed inside of a 300x250 .FLA

      -Comps rendered directly from Adobe Media Encoder standalone instead of Render Queue in AE (for 2 pass .FLV's, and heard from various that .FLV's from render queue are not the prettiest at times). 

       

      I've always been under the impression that I would get smaller file sizes with SWF's externally linking to an FLV.  If I do it this way, I end up with: 

       

      41 KB .SWF  + 668 KB .FLV = 709 KB

       

      However, if I EMBED the same 668 KB .FLV to the FLA's timeline (not using the flvPlayback component) I end up with a 381 KB file size!

       

      I am just confused on the logic here, could someone explain the reasons for this?  I always thought my file size would be bigger if it was embedded to the timeline.
