Hi, how would you guys fix audio suffering from PAL speedup ? To be more precise, I have a LD -> DVD transfer of Queen's concert in Budapest 86 in fantastic audio / video quality, the problem is that the concert was shot on film, so the incorrect pitch makes the concert unlistenable for me.
I usually used to solve this problem with AviSynth
[q]
AssumeFPS(24, sync_audio = true)
ConvertFPS(25)
[/q]

but a lot of people think it's a bad idea. I had now the opportunity to watch my previous attempt on an LCD TV, and the video has something which is best described as "motion blur". Since I have the original transfer in ex. quality, I want to do a version 2.0 . Any ideas ?

The easiest way would be:

assumefps("ntsc_film", sync_audio=true)
lanczos4resize(720, 480)

Then encode as an NTSC DVD.

Pitch correction for the audio, keeping the PAL running time, is possible but may add unwanted artefacts, especially in music.

Then there's the DGPulldown method. More information in this thread: http://originaltrilogy.com/forum/topic.cfm/A-pitch-corrected-Star-Wars-for-PAL/topic/8992/

Wer-al_zwowe created 2 different LD to DVD transfers of this. His second version has the corrected audio. Maybe you have his first version or a transfer by someone else?

No, it's a different transfer (at least the menus are different :) ) I'll try to do it as NTSC
