Google for interlacing artifacts. Displaying interlaced video on a progressive scan monitor will show the interlacing on moving objects.
It's not as noticeable on an interlaced monitor because it's only displaying one field at a time. Persistence of vision of the human eye helps smooth the field to field transitions. That also exaggerates the blur and jagged edges when viewing interlaced video on a progressive scan monitor. The easiest way to avoid it is by shooting in progressive scan. The playback hardware (DVD or Blu-Ray) will take care of converting to interlaced mode if required. For video shot in interlaced mode, you either keep it interlaced and ignore the artifacts while editing, most players and TVs will automatically switch to interlaced mode when fed interlaced video, or you can process the video through a deinterlace filter. Such filters process every frame, comparing to the frames before and after, then smooth out the fringing and jaggedness. How well it works depends both on the source video and how good the filter is written. Deinterlacing can create its own set of artifacts like blurred edges. In general, the faster the motion and/or the higher the detail, the poorer the results will be from deinterlacing. Your wind blown grass has both fast motion and high detail. Try deinterlace filters on a clip and see if you're happy with the results, both on progressive and interlaced monitors. --- On Mon, 6/13/11, TCD <[email protected]> wrote: > From: TCD <[email protected]> > Subject: Re: [AP] Digest Number 3800 > To: [email protected] > Date: Monday, June 13, 2011, 1:09 PM > > Hello Julian, > > > > > The wavy blur is in the movement of the grass mostly and in > the leaves of the trees. > > Very noticeable on windy days.
