    I have a NTSC 720x480 Progressive video source and when the film pans the picture stutter.
    I live in a PAL country and the sutter appears both in my computer and DVD player.

    Can I reverse the deinterlacing and re encode the movie into NTSC interlace 29fps

    or are ther other fine solutions ????

    regards stars....

    OK..

    I have looked deeper into this matter and it seams to be a realy dead end...
    That will say..if I cant get hold on the source.
    Since I live in a PAL country I (we) have some problems with NTSC DVD...
    Especially when there is a slow pan in the movie, it tends to stutter.

    I personally solved the problem, by seting all my viewing devices to the NTSC system.
    And did you know what...every PAL movie also started to stutter when there
    was a small pan in the movie....so I have to change my config depending on what system
    the DVD have....

    regards stars...

    Just my 2 cents.

    I find that horizontal panning stutter is present on any film or video source. Unless the pan is very slow it will appear to stutter or jitter. This is because of frame rates are the just too low. Film will look worse as the frame rate is 24fps compared to 29.97 for NTSC video.

    Many years ago Douglas Trumbull, film director and SFX creater, developed a film system called ShowScan where the frame rate was about 60fps. Sadly It never caught on and the industry limited their focus to resolution only.

    IMO, we really do need an increase in frame rate. Video would be much smoother.
