I've been thinking about taking DVD's of my silent films and extracting the sound track to edit it for the film. Has anyone tried to do this on the forum and if so, what was the result? I'm open for tips and suggestions.

Thanks

Not sure exactly what you're trying to do...extracting the soundtrack from where?

I'm going to attempt turning the soundtrack of a DVD into an mp3 file and then burning it onto a CD. I will then attempt to sync the CD to the beginning of the film. I was wondering if anyone has attempted this and were they successful?

Hi James,
that sounds very tricky given the chances that most standard 8 machines will not be capable of maintaining a perfectly regular speed.
Though if the original sound was essentially 'wild' (no lip sync) this may be enough,

I thought of the projector speed so I was going to record my film to the computor and match the sound that way. It probably won't work, but I keep reading about re-recording super 8 so that's why I started thinking about doing this.

Why not just play the dvd and project the film and see what you get for synch? The DVD will play back at the same time each time it's played (unlike videotape).

BTW if you extract the sound and then want to burn it to a CD, you'll have to have a CD player that can play MP3 or convert the sound to CD format which will limit it's running time to that a of CD.

Just play the DVD and if you can adjust the speed of your projector, do so to match the sound track. Generally the re-recording involves taking a synch pulse off the dvd player (from the video output) and using it to drive the projector motor to keep at constant speed. This is much easier in Europe with 50hz power and 25 fps video than it is in the US with 29.97 video (or 23.97 film) and 60 hz power so there's some "jugling" involved in the electronics.

Thanks John, something to think about.
