  • What deinterlace method for progressive from the beggining to the end.

    Posted by Márcio Nascimento on February 25, 2015 at 2:46 am

    Hi all!
    My original footage is 1920×1080 24p, shooting with Canon 6D, Canon T5i and Canon T2i.
    My project properties are the original Vegas template HD 1080-24p (1920×1080; 23,976 fps) (as showed in the picture)
    My final media is Bluray 24p (progressive) and DVD NTSC 29,97 (with pulldown). Both rendered in Sony DVD Archtect.

    My doubt is: If I shoot in progressive, edit in progressive, and render progressive, what do I have to choose in Deinterlace method? None, Blend Fields or Interpolate Fields?

    Another question, but not so important for this moment: Does “Reduce interlace flicker” at event properties makes any difference in final media when using progressive footage? Should be enable or disable? Or should this option be enable only when flickering appears in the final media?

    Thanks for all!

    You got it wrong. The 60i will not be called deinterlaced, it will be interlaced.
    A de-flicker filter will apply a softening on image in order to eliminate flicker.

    Hi Sorin, thanks for your answer, but I didn´t understood your answer. I´m not working with 60i, only 24p.

    [Márcio Nascimento] “My doubt is: If I shoot in progressive, edit in progressive, and render progressive, what do I have to choose in Deinterlace method? None, Blend Fields or Interpolate Fields?”

    You should leave it at the default which is Blend Fields. It will probably never be used because your footage is not interlaced. This setting will only affect interlaced footage.

    [Márcio Nascimento] “Another question, but not so important for this moment: Does “Reduce interlace flicker” at event properties makes any difference in final media when using progressive footage?”

    Reduce Interlace Flicker has absolutely no effect on progressive footage so it will do nothing whether on or off.

    Thank you John, this is exactly the answer I was looking for.

    So, if I use progressive source (Canon 6d) and interlaced source (Sony NX5) in the same project (1080 60i), what should I choose in project properties and in reduce interlace flicker of interlaced media?
    Today, to obtain a best quality in this case, first I render to mp4 30p, and later I render this mp4 to a mpeg2 for dvd.
    If I don’t do that (I mean, if I render direct to mpeg2), I can see in the final mpeg2: lines in interlace source and a ghost effect in the progressive source.

    You always want to select a deinterlace method, especially if you have interlaced footage in your project. Keep it at Blend Fields unless you see problems in high motion video. Then you can switch it to Interpolate Fields but this halves your vertical resolution so only use this when it’s needed.

    You would only use Reduce Interlace Flicker if you see interlace flicker. This usually only happens with still images. It’s important to not turn on fixes for problems that you don’t have.
