AVI NTSC to KDVD PAL?

rds_correia · #1 08-30-2004, 01:16 PM

Hi there

I knew this would happen to me sooner or later, I just expected it would happen later

I have searched the forum looking for ways to do this but I ended up with 77 pages full of posts that do not
show me how (at least until page 15

).
My problem is I have and XviD NTSC source that I need to convert to KDVD PAL.
Here are my source specs taken from Gspot:
Video
X,Y - 576x336 (1.71:1) [=12:7]
FPS - 23.976
Audio
Bitrate - 132 kb/s (66/ch, stereo) VBR LAME3.89
Fs - 48000 Hz
Apparently my system has the appropriate codecs to read the source correctly.
The problem is both my SAPs seem unable to properly manipulate NTSC encodings.
So it seems I really have to do a convertion.
If anybody knows where I can find a post with these answers don't bother explaining it gain

just point
me where to find it

.
Cheers

The process is really simple, this script would do the conversion for both video and audio:

Code:

AVISource("path\clip.avi")
EnsureVBRMP3Sync()
Trim(0,0) # EnsureVBRMP3Sync somehow needs this to work properly!
#Filter here
BicubicResize(672,432,0,0.6) # 2 overscan blocks assumed
AddBorders(16,72,16,72)
ConverttoYUY2() # for CCE
TimeStretch(tempo = (100.0*25.0)/23.976) # audio 23.976->25fps
AssumeFPS(25.000,false) # video 23.976->25fps

You can then extract the audio by loading the script in VDub and saving the audio track.

Hi:
If you are using avs script it is enough to use a line = assumeFPS(25).
If you are using Mencoder you only need option -ofps 25 (together with another settings that you want)
You should transcode audio with Besweet OTA option = -ota( -r 23976 25000 )

Edited: Audio pitch will be shifted but only a little bit, with not problem.

Using TimeStretch doesn't alter the pitch and should also be higher quality than OTA in BeSweet. You'll probably need the latest Avisynth 2.55 though.
