OK I need some help from the guru's...

I have footage that was shot on a DVX100B / SQUEEZE @ 30p. (approx. 50 minutes worth, from a live event)

Captured into a DV NTSC / 29.97fps / 16:9 Adobe premiere CS3 project. Once imported I get the red line for renderring??? I have tried to export via Encoder in a H.264 / NTSC / 1280 X 720 / 29.97 / Progessive, format.

Once exported the mp4 is extremely jerky, not smooth at all. This is raw footage, noe editing, color grading yet, just wanted to see how the workflow went, and I just can't seem to figure it out.

I forgot to mention that I captured footage live via On-Location and just imported the avi. I did record to tape also, but I don't believe that this is an issue, as I had the same results last night in a short test of footage recorded.

Any thoughts or ideas would be greatly appreciated. Final output will be for web via BLIP-TV.

No problem w/ original file in Media Player, plays crisp...

Why is it that the file needs to render when it is brought into the timeline?
 
I would only attempt to edit the RAW DV stream. Do not attempt to convert it to other formats, as you are adding more work for the CPU to do.

Even though a file plays back just fine in windows media player, does not mean that you can edit it in your favorite NLE. NLE's require less of a buffer, and lower latency to play back files, therefore a media player is not a good test for editability since the media player can use a very large buffer, with high latency.

If you use Premier Pro, the DV should save into an AVI container, edit those files, and when you are ready to show your work, export to an h.264 or windows media.
 
Therein lies the problem. I brought the original "raw" file into a Premiere pro timeline and then went to export via encoder to a h.264 format. This is where I am getting the "jerky" footage. I exported as a flash file and it is good. Why would the h.264 not work correctly?

More than likely its either a Frame-rate mismatch, or the PC/software you're using to play back the h.264 isn't fast enough to handle it.

check this Thread for exporting to answer some of your questions:

Also don't use quicktime player to test h.264 files. You'll see gama shift, and broken playback on high profile h.264 files.
