Flickering images in Adobe video products
Hello all,
I have a re-occuring problem with AE, Premiere and Encore. Essentially, when I use any graphics (such as PSD or AI files), photos and add any motion to them, I get a flickering effect on the edges of finer detail. It also happens when I use smallish fonts in Encore Menus(not too small though 14-16 pt stuff)
In AE I can reduce this effect by applying motion blur, while in Premiere the anti-flicker filter or one of the blur filters reduces this somewhat. The problem is the effect is still there to an unreasonable extent, not to mention that using a blur filter reduces the clarity of my footage.
I was thinking this may have something to do with field settings but everything I use follows standard adobe settings (i.e. I create all my project and compositions using settings from the pull down menus). I use PAL (I’m in Australia).
I am at a loss as to why this is happening. The strange thing is last year when I was using an old canopus storm and their proprietry editing software I never had this problem. Then again, up until late last year I didn’t do a heap of compositing where as nowadays I regularly do. I have recently upgraded to the Production Studio, which has not improved this effect even slightly.
Any help would be greatly appreciated.
Many thanks,
Timothy Eng

Flicker on fine lines can be alleviated in AE by applying a .5- or 1-pixel blur to an adjustment layer over the comp. When rendering fields, the blur should be vertical.
If you apply the blur to the layer itself (the photo), you should take into account any scaling that you’ve done to the photo when calculating the blur value. An image at 20% would need a 5-pixel blur to get a 1-pixel blur look in the comp. What’s relevant is the amount of blur in the comp. It’s just easier with the adjustment layer.
Does that help?

Have you tried the Reduce Interlace Flicker effect under video?

Hi guys,
Thanks all for your help. Adding a blur or the flicker removal does improve the quality however there is still a tiny hint of it there with the really fine detail. But it is starting to get a tad too blurry for my liking. Maybe I’m being a little bit over zealous here.
I was thinking it may be a work flow issue and I am attempting to use graphics with too fine detail. What are your thoughts and own workflow methods on creating graphics with finer detail? Is there some dos and don’ts that anyone thinks will help?
Thanks,
Timothy Eng.

Welcome to video…. Interlaced video only has the illusion of being sharp. Too much detail and you get moray patterns or flicker. The minimum horizontal width for any detail is actually 2 pixels. Even progressive rendered video is interlaced on a TV or CRT monitor, it’s just that both fields are identical slices of time so you are still limited to the amount of detail you can display. The trick of good design is to make it look sharp, even though it really isn’t.

Hi,
I’m experiencing the same with Final Cut Pro when zooming in/out or panning still images, and it would seem that this is really caused by the excess of details/thin lines. I’ve tried everything has been suggested here and in other pages to solve this problem, but I’ve really never got the result I’m looking for.Although I’m still looking for a solution, I’m afraid it should be said that photos are not fully compatible with video, if zoomed or panned, unless we accept a lower quality output in our work.
I’ve also tried to switch on After Effects, but obviously the result has been the same, and the same will be with any other software we’re going to use.
Is someone agreeing with me about this conclusion, or if not, why?
Thank you very much for your opinion.My best reguards.
Stefano.
