Pal->NTSC problem with Chickenmans tutorial

vbimport

#1

Itried to follow ChickenMans guide where he says to edit the Avisynth Script to include lanczosresize(720,480) <-- change the 576 to 480
assumefps(23.976) <-- Include this line here

My problem is that where it says lanczosresize…it doesnt read (720,576), it reads (720,426) (or something of that nature, think it was 426 though).


#2

Is this a PAL AVI your trying to convert to NTSC, or is it a DVD. If AVI, what is it original dimensions (GSPOT will tell you).

The avisynth script would have also had an AddBorders(0,75,0,75) line under the lanczosresize(720,426), was that so ?


#3

Yes, that is correct. It was a PAL avi and it contained “AddBorders(0,75,0,75) line under the lanczosresize(720,426).”


#4

Then the correct script should read

lanczosresize(720,360)
AddBorders(0,60,0,60)

Thank you very much.

Hey ChickenMan, The encoded pulldown shows up at 29FPS NTSC in dvdlab…Should I encode the audio to 29 or 23 ntsc?


#7

23.976 fps :slight_smile:


#8

ChickenMan, is there a formula to figure out the conversion? B/c now I have a PAL avi, that wasn’t 426…I think it was more along the lines of 564. So I didn’t know what to change it to (as well as the addBorders line).

Check out AVIRES from http://www.videohelp.com/~jsoto/others.htm

Great, thanks again.
Do you have trouble with syncing the audio after you convert Pal->NTSC? I change the framerate and everything, but It doesn’t always playback correctly. Too much of a hassle; I even tried a different method by converting the PAl AVI to an NTSC AVI first in Vdub and using besweetGUI to convert the audio but it (audio) is still off by 1-2 secs. I think its more hassle than its worth. Is there any other program out there besides DVD snata that converts and encodes with the click of a button? DVDSanta works great, but the qual is lacking.

Never ever have audio sync problems unless the original AVI is crap to start with.

Best all-in-one AVI converter is The FilmMachine, in my opinion.


#12

Have you ever run into a problem with an avi, and no matter what you use to convert it, the audio is always out of sync? This has only happened to me with 2 PAL avi files. The actual avi plays fine, but after converting to dvd, it is always out of sync. Whether I use D2SRoBa, film machine, dvdsanta, etc.
