    Hi... I was searching the Internet for information on producing PAL
    formatted DVDs (I'm in the US) and noted two things. First everybody seems
    to indicate that it isn't easy and that the results might not be too good
    and second (and this is the important part) two pages indicated that "most"
    DVD players in Europe can understand/interpret a DVD written in NTSC format.

    Does anybody have firsthand experience with this? Put simply "is this
    true?" It would make things a lot easier.

    I'm no expert, but two things occur to me.

    1) The software on your computer does not care whether it products NTSC or
    PAL DVDs.

    2) Have a look at some european shopping web sites for info on whether their
    players will do NTSC. Certainly the vast majority of Australian and New
    Zealand players and TVs sold in the last 3-5 years available will handle

    Agreed. Most recent DVD players and TVs imported for sale in the UK can
    handle NTSC source material and as far as authoring DVDs goes, whether the
    video is encoded as NTSC or PAL is irrelevent. Having said that some people
    (myself) included experience flickering when NTSC DVDs are played back on
    non-100Hz scan TVs. Given a choice I would prefer a PAL encoded DVD and
    despair when films such as "Shrek" are only available with DTS soundtracks
    on Region 1 (NTSC) DVDs.

    The difficulty comes when you have MPEG2 or DV video files that have been
    encoded in NTSC format. They will be either 24 or ~30 fps and need to 25 fps
    for PAL and therefore the audio speed will have to be adjusted and
    re-synched to the video. The images are also interpolated vertically to
    convert the 480 line NTSC image to 576 line PAL. This can lead to some loss
    of quality in the conversion to PAL.

    If you are in NTSC land, then probably most videos will be
    23.976, 24, 29.97, or 30 fps. PAL needs to be 25 fps.

    For 23.976 or 24 fps, the usual solution is to just speed up the
    frame rate to 25 fps (this also involves speeding up the audio by
    about 4%, sometimes with pitch correction).

    For 29.97 or 30 fps, your choices are more painful, and generally
    involve dropping 4/5 of the fields or frames, and then speeding up
    to 25 fps.

    Additionally, PAL/SECAM has more lines than NTSC. Interpolation
    usually works pretty well.

    Many video systems in PAL/SECAM land have some provisions to support
    playback of NTSC material. The results can be better than you converting
    NTSC video to PAL, but can also be worse.

    That is "what has to happen" but I find it hard to believe that is "what
    people do." Perhaps somebody who works with NTSC but has produced PAL can
    mention what they did. If it involves hand selecting frames they can let me
    know what they charge per hour.

    More importantly I was really trying to establish what an option in a video
    editor (in my case Vegas 4.0) that says "render as PAL" will produce. If it
    takes nothing more than choosing that option then all the math gives me
    something to think about as the software is busy rendering but little more
    than that.

    One concern is that I can't view the thing before I send it off. At this
    point I think I might try rendering a version in PAL but send an NTSC
    version along also. It's probably time to hit the Vegas site to see what
    they have to say about it. I assume they sell it in England.

    Of course you can view it, on your PC using PowerDVD or WinDVD.
