  1. hello

    i found that QTGMC() is doubling the frames in the video so i have 50FPS and not 25FPS.
    and i see that it is not Damage the quality.

    This enhances the movement and the the movement looks really good.

    but i know that if i will add SelectEven() after QTGMC( Preset="Slow", Sharpness=0.75 ) so i will get the correct FPS rate (25FPS)..
    but in 25FPS the movement is not better.

    but i sow that People recommend for 25FPS..
    why?

    It does not lose frames?

    PAL DVD is usually 25FPS interlaced. So, to re-interlace:

    Code:
    QTGMC( Preset="Slow", Sharpness=0.75 )
    ... run some processing...
    ... run some processing...
    AssumeTFF().SeparateFields().SelectEvery(4,0,3).Weave()
    If your original PAL source was BFF, replace "TFF" with "BFF".

    In what context ? There might be some reasons you have to change it to 25p e.g. youtube doesn't support 50p


    If you're leaving it progressive, then keep it 50p . 25p would be half the motion samples

    If you're interlacing it, then that's 50 fields per second , 25 frames per second . It's 25 frames per second, but still has 50 motion samples per second

  4. i dont care about youtube... i playing this on my Xtreamer and PC.
    50P is Better then 25P?

    Do most modern players can play 50P (not DVD players)?
    this is very important question for me.

    i dont know what is the Difference.
    In any case I get a good result ..

    Why is this important?

    EDIT:
    there is no "DVD" in this story..

    Yes 50p is better than 25p - motion is more smooth . You throw away half the frames when you use selecteven()

    Yes PC can play 50p . Modern hardware players can play 50p for SD resolutions , but most currently have problems with 1080p50

    Re-interlacing is only if you are going back to DVD or SD blu-ray . IMO if you're going through the trouble of using QTGMC, you might as well leave it progressive

    As I thought. I just wanted to be sure.
    so Why all the releases (movies, series, etc.) are 25p?

    I do not get it .. the Movement is less smooth.

    Because movies , tv series are currently and used to be shot on film (24p) , and sped up for pal regions (25p) . But nowadays, more and more are using digital cinema, but still use 24p

    Soap operas, Sports, use 720p59.94 or 1080i59.94 (in 60Hz regions like North America); or 1080i50 or 720p50p (in 50Hz regions, like UK, Europe)
