  • NTSC & PAL FLICKER

    I have a samsung VCR capable to convert NTSC
    to PAL and viceversa.
    Since i have a digital camcorder in pal format and my project is in NTSC i had to use my VCR to convert the video signal.
    No problem so far.
    My VCR does a pretty good job in the conversion but.... during playback of converted pal to ntsc scene in a ntsc timeline, an expert eye can still see some kind of flashing or pulsing in the clip.

    I have MATROX RT2000 and i use premiere 6

    ANY SUGGESTION TO FIX THIS PROBLEM ?
    I TRIED remove flicker but that strange effect is still there.

    Thanks

    How does it look if you edit in PAL and convert the output signal to NTSC in the vcr?

    Perhaps more importantly, how does it look on a NTSC reference monitor?

      I could do that, but since my other two cameras are NTSC, then i would probably have same kind of effect in the "ntsc to pal" scene.
      Basicaly i'm mixing pal and ntsc clip together so... i gues somewhere i have to apply some kind of filter.

      Any soggestion for combination of filters in premiere ?

        What frame rate do you use for NTSC capture?

        just how bad does it look on the finished tape master? Is it a serious distraction or not particularly noticable?

        Computer monitors are notorious for showing video artifacts that will never show up on TV.

          well, the problem become noticable in clip with NO MOTIONS. If you have a scene with no motion (kind like a still) you will see the screen going up and down kind like shaking verticaly. only in this kind of situation you'll see the problem very clearly.

          I use default setting for my capture (29.97 i guess)

          there also another particular that i had notice... whenever there is the color red or something red in the clip, i can see it pulsing and flashing...

          i guess the best thing to do is post a little avi file so who what help me, can see what i'm talking about.
          I'll do it tonight at home.

          Thanks again

            Normally PAL is 50Hz
            However some equipment converts it to PAL 60Hz (e.g.DVD-player).
            So the 10 additional Hz have to come from hyperspace
