hi, sorry for my english, i'm brazilian...
i'm having a problem, i have a 512x384 video at 23,976fps and i want
to burn it in SVCD NTSC format... i've tried tmpgenc, it converts to 29,976fps but when i play it my DVD the playback isn't smooth... i was looking for a avisynth script that does it... not necessarily an avisynth script... i'm accepting anything that does it for me...
i'm having this problem for 2 weeks ... please help ...
thank u

You don't need AviSynth to make it 29.000 fps. Just perform a pulldown to your video when you've encoded it. You could use e.g. BBWoof's DoPulldown (http://www.woofsoft.com/Downloads/53.aspx) to perform a pulldown.

Regards,

# JDL_Telecine
#
# Telecines a clip.
#
# Useful for dealing with hybrid material when the final format is
# interlaced.
#
function JDL_Telecine(clip c)
{
assert(c.IsFrameBased(), "JDL_Telecine: clip must be frame-based")

# we need to handle the case of a null-clip manually;
# otherwise, SelectEvery(...) will generate unwanted blank frames
return (c.FrameCount() == 0)
\ ? c.AssumeFPS(c.FrameRate() * 5.0 / 4.0)
\ : c.ComplementParity().DoubleWeave().SelectEvery(8, 0, 2, 3, 5, 6)
}

i enconded doing pulldown with tmpgenc, but it didn't work....
the playback still not smooth... do u think i need to do a real framerate conversion to get smooth playback?

TMPGEnc-Settings for 23.976 FpS are:

Setting -> Video -> Encode mode -> 3:2 pulldown when playback

Setting -> Video -> Frame rate -> 23.976 (internally 29.97 fps)

Setting -> Video -> Video format -> NTSC

Setting -> Advanced -> Do not frame rate conversion

Are you positive that you're setting the field order right in tmpgenc?

On progressive Source and progressive Output, the Field Order doesn't matter. But to be sure, set it always to TFF in this case.
