Hi, I have a bunch of digital photos I'd like to set to music so that the photos transition in time to the rhythm of the music. I've tried doing it manually with video editing software and it's very painstaking, but it seems to me this is the kind of thing that could be done automatically using similar logic to those irritating "visualisations" that seem to be de rigeur on all music playing software. It wouldn't have to be real-time. I'm actually looking to make DVDs out of it. Needs to be PC though, not mac/linux. TIA for any suggestions Andy
software to set pictures to music

Hi Andy, my first thoughts to solve that problem would be to generate some transition signal for the pictures from the sound files, i.e. to extract the "rhythm of the music". You have to ask yourself how to define that. With electronic music it basically comes down to a bpm-counter-problem, which shouldn't be too hard to solve, I would assume a relatively basic time domain algorithm, possibly just a peak search, being successful. With other music, you'd need to extract e.g. the drummer's sound, which is somehow more difficult, incorporating some kind of filter for example. But haven't done that. Just some ideas. Good luck, and give some feedback some time. stereo Andy Fish wrote:> Hi, > > I have a bunch of digital photos I'd like to set to music so that the photos > transition in time to the rhythm of the music. > > I've tried doing it manually with video editing software and it's very > painstaking, but it seems to me this is the kind of thing that could be done > automatically using similar logic to those irritating "visualisations" that > seem to be de rigeur on all music playing software. > > It wouldn't have to be real-time.

Thanks for the hints I'd be surprised if there wasn't already some kind of library already available to do this though (or even an off-the-shelf application to do exactly what I want) Andy stereo wrote:> Hi Andy, > > my first thoughts to solve that problem would be to generate some > transition signal for the pictures from the sound files, i.e. to > extract the "rhythm of the music".
