    Adobe Media Encoder CS4 Causing Jerky Playback with Speed Changes


      Here is an Matrox AVI that was captured in Adobe Premiere Pro CS4. Watching the edited clip with a speed change of 600% looked fine when played in Premiere Pro CS4.


      When I export the clip using Adobe Media Encoder CS4 as MPEG2 Blu-ray with a preset of 1440 x 1080i High Quality playback is very jerky. An export of the same clip with normal speed looks great??


      Any suggestions would be greatly appreciated
