Hi everyone smile.gif

I have a couple of old concert movies on DVD that run, in Sound Forge terms (if that makes sense?) +50 (or half) a semitone fast. Is there anyway to change the playback speed of the film and audio?

Many thanks for any suggestions smile.gif

Friend, you got really sensitive ears. Half a semitone, I wouldn't even notice. Anyway, to answer your question, it depends on your playback software. I use Winamp and the Pacemaker plugin. It can vary pitch and tempo independently or both together. I use it frequently when watching videos. If I slow the tempo just a bit while maintaining pitch, I can understand the dialog more easily. In your case slowing both tempo and pitch by about 3% should do it for you.

winDVD is (also) able to change playback speed (maybe is a 24->25 fps transfer?, are you in a PALcountry?)

Thanks for the replies smile.gif

I am indeed in "Pal Country" and was wondering if the 9% (?) speedup was to blame. Of the three examples I can think of off the top of my head the speed/pitch is either up a half or to nearly a whole semitone.

I have tried WinDVD but even with that effect it was either too slow or fast. The adjustment wasn't fine enough. Plus I'm really looking for something more permanent as I don't really watch films on my PC.

I have various bits of software I suspect could do the job but I confess the whole frame rate thing (if that is the route to go) is all a bit new to me. What values to alter/enter ect.

Again, any help is much appreciated. Thanks again smile.gif

Grim177: you either need to change the playback speed back to original (24 fps), but that will require either:
a. - some NTSC-ish pulldown joke (not recommended) - to get NTSC DVD
b. - some sort of frame interpolation (not recommended) - to get new PAL DVD
or
c. - changing the pitch of the audio somehow (but the audio will still be wrong speed) - and that would mean reauthoring - to get new PAL DVD
