De-Interlacing Photoshop Menu?Posted by aquaimage
I have a number of menus that I have created for a DVD I am working on. The menus are being used as slides, so that people can go through them at their own pace. They have been imported to DVD Studio Pro as TIFF files. Then the project was burned to disk.
When each file appears on my CRT Sony TV, each of the images appears to jump up the screen slightly and then settles back down. I am guessing that this is an interlacing problem? In Photoshop there are four choices for de-interlacing. Eliminate odd fields or Even Fields? Create new fields by Duplication or Interpolation? Can anyone tell me which set of options to choose? Thanks!
Is the sequence fully rendered? Sometimes you see this shifting if it isn't being displayed at full render. Make sure 'full' is ticked under the Sequnce > render all option, then use option r to do the whole timeline, then check again.
If it was an interlacing problem you would be more likely to see the flickering for the whole duration of the still. For interlacing in PS, you can choose whichever set of options works best for your picture. Sometimes you want the first field, sometimes the second. Most of the time it doesn't even make much difference, unless there is a movement in one frame you want to get rid of.
Hi aquaimage,
This is basically means what it says. >Eliminate odd fields or Even Fields? You have information on odd or even lines. To deinterlace it, you need to get rid of one of them (effectively halving your image resolution). >Create new fields by Duplication or Interpolation? Duplication, also known as line-doubling, will duplicate the remaining field to fill back on the missing information. Interpolation will make a guess as to what the information was. (eg. line 1 black, line 3 white, therefore line 2 will be grey). www.strypesinpost.com
Not exactly. Not all the time. Sometimes duplication doesn't look so good. Just see which works in your specific case.
