Getting up to speed

[DanceCatDave]

Hey folks,

Rank noob here, and not sure where to post.

I'm an amateur DJ and use software for my music (Traktor, specifically). I also have a number of videos of light effects, animals "dancing", etc. I would like to combine the two, using VLC.

My thought is this: Computer 1 will output the music to the mixer, as well as to Computer 2. Computer 2 will read the BPM of the current song (based on MIDI information, for example), and automatically adjust the VLC playback speed to match.

For example, I have a video of a bird bopping its head at 100 BPM. When I play a song that is 108 BPM, I'd like the information to automatically adjust the playback speed up to 1.08 (assuming that "1.08" represents a 100-point graduation speed increase, as opposed to some other standard). I would also like it to "beat-match", if at all possible. That way the head isn't bopping at a 1/3 beat off of the music.

Has this already been done? CAN this be done?

Once I have the information, I can have someone write the script (or whatever), since everything I know about computing can fit in the word "nothing".

Thanks
