Flickery lines in moving images

[Richard Hutt]

I hope somebody can help Ashley cuz i am having the same issue and thats not good.

Hey Ashley
I feel your pain i have spent the past two and a half hours trying a lot of what I have found in the COW forum, with not much success.

In my project I have a group of JPGs, scaled to 25% with a sepia tone applied, moving across the bottom of the program monitor and there is a lot of shimmering. I started playing with the filters and the like ( and the Anti Flicker option under Motion in the Effect Controls panel isn’t worth a damn, it actually made it worse) and the best thing i found is to right click on the clip and choose Frame Blend. It knocked almost all of the shimmer out. Of course the project i am working on is going to be shown on a 10′ X 10′ projection screen so the potential for it looking like A#$ is great. Try this to see if it works for you

Can you describe your sequence settings in detail in Premiere?

Are you dynamic linking from Premiere to Encore, or are you rendering a file and using that in Encore? If you’re rendering a file, what are the exact settings you’re using?

Can you describe what “fickering edges” means to you? Do you see sharp horizontal scanlines? or…?

Without knowing too much, it sounds like you may have reversed the field order of your interlaced material. DVDs and Standard Def PAL are lower field, while an HD (60i or 50i) timeline has the default settings of upper field. May need to paste your cuts into a new sequence set to lower field dominance or double check that any PAL based video is also being interpreted as lower field (right click the file in the project bin, Modify >Interpret Footage)

Thanks for the reply Angelo. I am using Premiere Pro CS4 and the DV-Pal Widescreen 48KHz preset. And yes I also used dynamic linking to get to encore.

The best way I can describe the flickers is that they’re along straight edges mostly that create a jagged unstraight and flicker when the images moves. Sorry for the vagueness of this, not sure how else to describe. Ill try and upload an image.

I interpreted the footage for one of the images and it says progessive scan, is that right?

I haven’t edited in Premiere Pro very much (I normally use Vegas), but I have noticed over the years that sometimes if an image has a very high resolution, it will cause flickering. A lot of pictures that I get from graphic designers are high in resolution because they are using them for print, but it creates havoc in video. If you have a lot of photos, it will probably be a pain to decrease the resolution on everything, but it is an option.

You can fix this by setting your field order at exporting to “None (Progressive)”. It fixed the problem in my situation.

In my movie I’ve used a lot of HD images (3000x2000px) which were downscaled, rotated, bounced and moved all over the screen. I’ve tried a lot of different settings like “Field options > Flicker removal”, “Field options > Always Deinterlace” etcetera. It didn’t work.

Only by setting the export settings to “Field order > None (Progressive)” gives me the best result.

I hope you’re helped with it, otherwise maybe someone else is!

This was the exact fix that I needed. Thanks.
