Premiere Pro CS4 30p jagged edges/stepping

[outofcntxt]

I've been editing letterboxed footage shot with a DVX100B at 30p in Premiere Pro CS4 on a mac.

Captured using Quicktime DV/DVCPRO NTSC codec @ 4:3 aspect ratio, progressive, BEST quality.

Sequence settings are default Standard DV 48kHz (interlaced by default)

The problem comes for me when I go to export. If I export as progressive i get jagged edges or stepping along with flickering of thin lines in the image. You can see it in the image below in the window along the bottom of the blinds. It also causes what looks like aliasing of fine grids patterns (not shown in the image below).

If I export it as interlaced, I get a crisp image as in the image below

The problem is that I want to output a progressive video to be put on Vimeo, and I don't want to export the interlaced video and then deinterlace in a second step and lose quality.

I've been trying all different combinations of settings and it seems like progressive sequences don't play well with the captured progressive footage, and causes much worse stepping.

1) Any ideas what I am doing wrong? I have tried changed the field options and selecting "Flicker removal". It helps a little but seems to just blur the video and reduce the overall quality.

2) A related question: I understand that DV cameras like the DVX record 30p in a 60i format onto the tape. Does the capture process convert it to true progressive using the settings that I mentioned above? Or am I treating the footage correctly by putting into a standard interlaced DV sequence?


Thanks for any help in advance.

Did you solve this yet?

Have you tried interpreting the footage in the project window? It's possible you are throwing away half of your vertical resolution if premiere is interpreting the footage as interlaced to being with.

Try right/control clicking on your footage in the project window, select modify or interpret footage and conform the footage to no fields progressive).

I believe the deinterlacing in Adobe Media encoder isn't the greatest. You'll need to dig into an AVI-Synth script or hire a professional if you want a good de-interlaced copy.

I was having the exact same problem with Premiere CS5. After spending hours trying different combinations of output settings in the Premiere Media Encoder, my final solution was to export as a sequence of tiffs, import the sequence into After Effects, and then use the After Effects render queue to output my final video (h.264 in my case). The only drawback is that you need A LOT of hard drive space to do this (using my 30P DVX100 footage as an example, each tiff in the final sequence was 1.4 MB, which equals roughly 2.5 gigs per minute of video. Good thing hard drives are getting cheaper.
