Animating a still from large to small gets jaggy

[Ann Bens]

Try setting the field options to alwayd deinterlace if your timeline is interlaced.
What are your project settings?

Thanks for your response Ann,

I am on DV NTSC Wide Screen, working on a PC, PPro5.5 My system is not having trouble handling the file size, just a little long to render, but not bad.
I’ve tried it both with and without the always deinterlace setting selected. I assume the timeline is interlaced, I don’t know how to determine that.

When the photo comes on the screen, it is scaled at 112 and it’s a perfect photo. Then I scale it to 14. When I scrub, the jaggy lines start appearing at 44. I’ve burned the short section and watched it on a small widescreen, an old television and on an iMac and it looks nasty on all three.

Thanks for your help

If you can make the file a little bit smaller b/4 import it might help.
If you change the DPI to 100 from 300 b/4 import it might help. (Some disagree)

If you save the still as a PNG file b/4 import it might help.

Thanks for the response Chris,

I reduced the dpi from 300 to 100, made the pixel dimensions 900 x 1209 and saved it as a PNG. It came into Prem smaller, and the details when enlarged for the timeline are still good, but when I scale it down to show the whole photo, it’s still jaggy and far from a crisp photo. I brought the file into my iMac to see if that made any difference, but it looks the same in Prem there too.

Do you or anyone else have additional ideas, I’d love to hear them.

Thanks!

Well the DV codec is the worst, bottom of the barrel for quality.
Change sequence settings to 8 bit Uncompressed will yield much better results.

OR

Export to a much higher quality codec when the edit is locked.

I always achieved better results using Effects / Video Effects / Distort / Transform, instead of Effect Controls / Video Effects / Motion. It always seemed to render better, for resizing or tracking stills.
Transform also has a parameter for Shutter Angle, which helps to make the motions more natural looking.

Thanks for your reply Vincent, I tried your suggestion, (which BTW I never knew existed) but still get a jagged image. The other photos in the montage are fine, even the ones that pan and zoom. For some reason this one photo, which is from a professional photographer is not cooperating in Premiere. Since it is a pic of my nephew, I have a hard copy I pulled out and scanned as a large file. It’s a great photo, works well when enlarged, details are great, but when I scale down to the small size, as it gets half way to the size I need, the jaggy’s start creeping in. Is there something about taking a large photo image and reducing it that Prem doesn’t like?

Thanks for any help

I have found (in FCP anyways) using a still that is really large and having to go down to 20% for some part of its move, didn’t always look the best.
That’s why I suggested not having it as big to start with. Make em just large enough for the move needed.

But how you are viewing this image matters~your computer screen is not how to judge video.

The codec used in your sequence matters a whole lot.

Stills:

RGB
72dpi
PNG

Dpi means nothing in video, its just for printing.
What counts are the pixels.
One has to remember stills look great in Photoshop at full resolution.
In a dv timeline which is 720×480/576 the still gets reduced enormously loosing a lot of sharpness.
Zooming over 100% also means quality loss regardless the length and width of the still.
Imo its best to use psd or png’s.
There is also a technique where you unsharpen mask the Lightness in Lab Color Mode.

What you are describing about having a really large still and reducing it down and it not looking very good is exactly what I’m seeing here.

The image is RGB, I’ve tried it also as a PNG, but never dropped dpi below 175, but I’ll give it a try.

Thank you for your response, I appreciate it
