de-interlace & progressive scan
OK, this gets the dumb question of the week award! I am a seasoned user of FCP, but for the life of me, I don’t understand the difference of de-interlacing DV footage from progressive scan, and which way is the best to do this. For example, I could slap the “de-interlace” filter on all the footage, or I could set the sequence’s field order to none. This would accomplish the same end result, wouldn’t it? Or can’t I do this in compressor too? I guess my question is 2-fold:
Is de-interlacing and progressive scan the same &
What is the best way to de-interlace interlaced footage?Thanks! 🙂

That turorial, although it is in after effects give the jist of how a basic deinterlace filter works.
Deinterlacing is the process of making footage that was shot interlaced, more appropriate for viewing on a progressive scan monitor.
This is done by interpolating the data in the lines that were not recorded in each field, often sacrificing temporal resolutions and sharpness, to avoid flickering and stairstepping artifacts.
The best way depends very much on your footage, your deadline, and your delivery medium, and your and your client’s quality sensitivity.
Here is a technique lifted from:

From Joel Peregrine:
Highlight a clip, duplicate it and place it directly above itself in the same way your technique is set up. Set the V2 opacity at 50%. Now place the “de-interlace” filter (with the “LOWER” setting selected) on the V1 clip. Next, place “de-interlace” (with the “UPPER” setting selected) on the V2 clip. Thats it!!! No interlaced-induced flicker. Full resolution, No strobing, No jaggies, just a subtle, classy, non-video look.Me again…
For my time and money Nattress Film Effects is a good choice for this kind of work…
