Rippling Stills
What are the keys to making smooth, moving stills in PPro 1.5? I’m having a problem with jpegs rippling and looking jaggy when I move them or expand them for a “Ken Burns” effect (even after rendering). It seems like the jpegs that I download off the net (smaller file size) don’t have the problem as much as the jpegs that I create with my Nikon D70 (file size anywhere from .70 MB to 2.5 MB). It almost seems that the bigger the file, the more problems. I have tried de-interlacing in Photoshop before importing into PPro without any difference. Jpegs that look beautiful to begin with look ugly and jaggy in my sequence.
I’ve also tried the 1 pixel vertical blur, with little success.
Is there a “recipe” for a good still size in pixels, MB, etc.?
Thanks.

A one pixel blur for a huge file may be insufficient. The sharper the photo, the more the DV codec can not deal with the little tiny lines. Add additional blur. You can add quite a bit to a large file before you even detect it. If you are zooming in, you will want to keyframe the blur to be less at a zoomed in value than at a full frame zoom out.
There is nothing to deinterlace in a file fron a still camera. So that won’t actually do any good.

You are right about the lower resolution stills producing less flicker. The higher resolution stills are much sharper and the sharp lines are hard for the DV codec to handle. You can blur the photos like you mentioned, but just be more agressive, or you can re-size the pictures. The downside to adding blur in Premiere is the significant increse in render times. Re-sizing the pictures has been the best solution for me. I find that making the picture about 1,000 to 1,300 pixels wide (1.5 – 2 times the resolution of video) allows me to zoom in for the Ken Burns effect without flicker becoming a problem. If you are used to working with still digital files you will be suprised that a picture that looks very soft for print will look good on TV.

Thank you for your great recommendations! I have been applying the blur in Photoshop and then importing the still into PPro. In Photoshop I’ve been using the “motion blur” filter, on 90 degrees (vertical) and 1 pixel. I’m not aware that I can apply the vertical blur in PPro…can I do that instead?

Sure!
