Really? Because in Audacity there is absolutely no difference in length between “sped-up”-versions and tempo changed versions (I’ve just tried it, same length). I’d have to add though that I’m a sound-engineer and a musician, not a filmmaker!

Last year my record company produced a DVD of my group (not clips, but a live concert). I had nothing to do with the whole film editing but I absolutely hate it(picture quality is fine though): to busy and strange close-ups and all! It was all done on a Betacam system (and four camera’s). I wonder what you think of it, here’s a link to one of the songs: 1, 2

Your blog inspired me to try and make a clip of one of my groups using the speeding up principle. I am very curious to find out how that might work out, since I work in other music styles than pop (jazz, classical, tango).

Unfortunately, from what I have seen, it is not easy to sync back a sped up song that uses the original pitch. Might just be me, but I found this way to be easier for syncing.

About speeding up the music: perhaps it is a better idea not to change the pitch when increasing the tempo of the song. I’d much rather play along with a recording of myself in the original pitch. This way it is easier to relate what my hands are doing to what I’m hearing and I’m certain as a result the performance will be somewhat better! This can be done in audacity by using “change tempo” instead of “change speed”.

Best Wishes,
