  avoid ‘flickering’ panning photos

  Posted by Gunnar Kordestani on October 22, 2007 at 10:36 pm

  hi there,

  probably ‘one of these questions’ asked a million times and answered a million. But here it is again.

  What’s the trick to get best results with animated jpg’s?

  In this case I have them upright ‘standing’ like some screen in a 3d space, with a camera flying around (so in fact that gives us panning and zooming). The rendered result gives much ‘flickering’ or ‘jittering’ in the photos (especially all the borders an lines [stairs for example]). and on the borders of my mask i used.

  I found some hint about ‘field-render’ but I guess there is a bunch of things to take into consideration. So, let it flow, please.

  thx a million
  Gunnar

  In some cases rendering your file interlaced (i.e. with fields) will help cut down on the flickering.

  What FPS is your comp? Lower frames-per-second will increase flickering.

  Another option to try is turn on Motion Blur for the JPGs, and enable Motion Blur for the comp itself. This will eliminate some of the flicker at times when things move more quickly.

  it’s a 25fps comp. PAL but still square pixels.

  As It will we integrated in ‘normal’ Video later it has to result out as 25fps.

  If higher framerates do a better job, could it be an option to compose in (let’s say) 50fps on half speed an then render out at 25fps?

  thx …Gunnar
