      I am editing a music video where we shot a good deal of it with the audio mix sped up 100% and then filmed the band at 60 FPS, so that when played back they have that surreal, “singing and playing in real time but looks kinda slowish” feel. It’s been done a billion times and I know you know what I’m talking about.

      At any rate, when I right click on the clips in the timeline and choose “Speed/Duration”, then drop it to 50% (with the Frame Blend option checked), it plays in the source windows at a nice, smooth speed. But, when I render the clips out, suddenly they playback WORSE, containing jerky motion and it’s not at all smooth anymore.

      Can anyone tell me how to fix this? I’ve tried checking off Frame Blend as well but it still looks the same; clunky when rendered. I think it’s odd that it plays back so smoothly when not rendered (I’m assuming my vidcard is responsible for the video playback of unrendered clips?). Here’s some critical data that might help you come up with a solution:

      Shot On: Panasonic DVC PRO HD Camera w/ Red Rock Lens
      Editing: Adobe Premiere Pro CS3 (licensed)
      Editing Mode: P2 720p 60Hz DVCPROHD
      Frame Size: 960 x 720 (16:9)
      Timebase: 23.976 frames/second
      Pixel Aspect Ratio: HD Anamorphic 1080 (1.33)
      Display Format: 24 fps timecode
