whenever i load my script into ToK the FPS is set to 23.976, where it should be the standard NTSC FPS... i belive this may be causing me to loose CQ, so does anyone know a line for my script i can put in to set it to the default?


EDIT: i got a filter that will reverse telecine the movie, which will fix it. the filter is called IT (inverse telecine) but the instructions are in japaneese, thus i cant read it and figure out the command... so anyone who knows how to use this, or any other filters that do the same thing, please help me out

Ok, I'm not a specialist for NTSC issues since I live in a PAL area but...

I'm pretty sure that 23.976 fps IS the standard NTSC framerate, while 29 fps is for NTSC FILM (I could be wrong... maybe the other way round).
Inverse Telecine can also be done with the "Decomb Package" for AviSynth, as far as I can recall... You can download it from the AviSynth homepage www.avisynth.org .
Check the readme for further instructions...

If you encode in MPEG2, do not do IT at all. Change tempgenc settings (into video.en1 if you use Tok) to do a "3:2 pulldown during play".

Maybe you can see here the settings you need to perform a pulldown-flag setting during encoding a 23,97 NTSC FILM Stream.

Its part of a Guide of mine, but its in german so I send you this picture as part of the guide .... maybe its enough to understand.

Only change in TMPEGEnc the Fields with Numbers as shown here.
And do NOT set any other Pulldown options ins the Advanced settings!

This here refers to 23,97 FPS sources only!



You can just do your 23,97 Pulldown configuration as shown above and save it as a KVCD based text-project in TMPEGEnc and open this in CQ Matic - Thats all.

There's also a way in Avisynth to convert 23,97 NTSC to 29,97 NTSC before encoding to mpeg but its senseless, cause the encoder has to handle more picture-information during the encoding process in TMPEGEnc so you would receive less CQ.

Example:
You got a movie with 23,97 @ 480x480
1 Frame= 230400
*23,97= 5522688 pixels p. second
*60 = 331361280 p. p. minute
*100= 33136128000 pixels to handle by encoding a 100 min Video stream

And if you encode with 29,97 @ 480x480
This 100 min Video stream will take 41430528000 when encoding at 29,97 FPS

So this is why you would receive less CQ
(In this case when encoding a full Screen Movie, not a Widescreen! but in Widescreen mode we enjoy in relation the same advantage when encoding using 23,97!)


@ Jellygoose

NTSC FILM = 23,97 FPS / Progressive
NTSC VIDEO= 29,97 FPS / Interlaced

And here comes the hidden trap:
Also NTSC FILM = 23,97 FPS / Progressive / w. Pulldownflag
= Shown at PC as 29,97! hehe tricky... most blockbuster NTSC DVDs got a 23,97 with Pulldownflag.

So, is it better to convert to 29.97fps from 23.976fps?

because i have a xvid movie that is at 23.976fps

Sorry if that question is noobish

Source at 23.976 is the best you can have !
Encode in MPEG2 and set the pulldown to "3:2 during play" in tmpgenc settings.
