Wsola

[cinetango]

Hi to all. I have 2 DVD that I purchased on ebay to my surprise both are PAL. I am trying to convert them to NTSC using "Standards Conversion (on the cheap)" guide. I was able to download all the required programs except for WSOLA which I found on http://sourceforge.net/projects/mffmtimescale/
but I am unable to install it and run it.

Can someone assist me on getting WSOLA running?

Thanks

Hi-

I've never heard of WSOLA, but it seems to do the framerate change for you. It says that it doesn't alter the pitch. But you want to alter the pitch, to get rid of that awful PAL speedup. You don't need it anyway, though, as BeSweet will do it just as well. It even has a preset for it. So, I'd suggest converting the DVD's 25fps AC3 to WAV 23.976, and then convert that back to AC3 23.976. You can use BeSweet's AC3 encoder, except that I don't think it's very good. Much better for the job would be Soft Encode or some such.

I haven't read Xdeemi's (sp?) standards conversion guide, but the video conversion is easier than you might think (for movies anyway). You just have to change the resolution to 720x480 (LanczosResize(720,480)), and change the framerate (AssumeFPS(23.976)). Then, when done, run Pulldown.exe to set the flags so that 29.97fps is output from your player. And, of course, reauthor the DVD.

I didn't really answer the question, though. Maybe someone else has had experience with WSOLA.

Hi there,

I would use the "SoundStretch" facility as part of the SoundTouch package rather than WSOLA - it provided much better quality last time I checked (admittedly a long time ago):

Usage is similar to WSOLA:

soundstretch infile.wav outfile.wav -tempo=-4.2709376

to represent the 4.27% slowdown from PAL to NTSC
