encoded mpeg2 stutters when played – any thoughts
Encoding timeline mix of video, audio, and pictures using Premiere Pro 2.0’s adobe media encoder with following settings:
mpeg2; preset 1080 24p 15 MBps VBR.Resulting encoded video stutters and is slowed when played back using various players (windows media player 11, intervideo winDVD 5). I am wondering if anyone knows why. Possibly I need a different codec or maybe I have a glitch?
I am attempting to use this setting because it produces the highest quality playback as compared to mpeg2-DVD, SVCD, or other mpeg2 settings such as NTSC generic. I would be open to using other encoding settings if I can get similar quality and I cant fix my problem.
Thanks for any thoughts

Most computers could not decompress and playback smoothly any codec that compresses 1920 x 1080 to such a high degree. Less compression (higher bitrate) cause playback issues without at least a SATA Raid.
You really need much less resolution for local playback or author to a Blue Ray disc for playback on a Blue Ray player.
If for local playback, what is the resolution of your screen? -
If you don’t have one already, try a PCIe video card with HD playback ability, that should solve your problem. It’s usually a combination of decompression and updating such a large area of the screen quickly that causes systems to drop frames. Just about any recent ATI or Nvidia card has on-board processing to handle this.
I have two identical systems, one has a very low-end gamming Nvidia GPU (about $50), and one with a Matrox Parehlia card (about $350). The system with the Nvidia can play WMV HD clips all day without ever dropping a frame, the Parehlia can’t go for more then a few seconds before dropping frames.Jeff Kosmicki
