Getting interlaced exported output from a progressive source file.
I am using Premiere CS4.
I rendered using the YouTubeWidescreen HD preset.
My original footage is from a FlipHD camera (H.264)
My intention was just to make some cuts to the in and out points, but otherwise not alter the original footage.I am getting some sort of motion artifacts with the exported file. Looks a lot like interlacing to me. But the camera shoots in progressive mode as far as I know.
The first photo is a screenshot of the original footage.
The second photo is a screenshot of the export video file.
The person on the left is spinning around.
In the original footage, each frame is without any motion artifact even though the person is moving quickly.
How do I fix this?

It looks more like frame blending, which can happen when you shoot in a different frame rate than you edit/export with.
Take a close look at the frame rates of the footage and the sequence and the export.
Let us know.

Set the export frame rate the same as your footage.
Default is set to 24 frames. -
Yeah, frame blending. Thanks for that heads up!
I turned frame blending off for the source clips, and that fixed it.
Also, changing the sequence and export frame rate to 59.94fps also fixes it.There is something else I’d really like to understand:
Is there any way to get Premiere to just export the original source video without re-rendering/re-compressing?
This is way the way it worked with SD DV. If you didn’t add any titles or any other effects, it would just export the original file (fast).
It seems I am losing some quality no matter how I export it.
