pure data chopsuey beatslicer

a little demo video for chop-suey, a beat slicer i built some weeks ago with pure data. it features automatic slice detection and a sequencer with grainstretching, retrigger effect, pitch shifting.... sorry for the sync problems in the vid, i had big issues with that (i'm afraid that's because of my lack of experience in video editing...)! ;) for those who are interested, you can download almost all of my patches in the pure data forum.

this is a pretty nasty scheme! do you ever find yourself with GUI lag from the number of GOP objects in the patch? i've always had problems with the GUI locking up where if i had too many sliders/number boxes/etc. eventually they wouldn't refresh, although they'd still respond when you clicked and dragged on the them... but maybe it was just a bug from memory/processor restrictions. either way this is pretty sweet, you should combine it with my GEM video patch!

yeah, pd's gui is kinda crude and much too expensive, but i had no issues with that patch here.

sorry for the sync problems between video and audio, i don't know how i can avoid that. if someone could give me a hint, i'd really appreciate that.

what'd you use to record? my oldschool method of recording GEM output was to dump every frame to a jpeg and record the audio separately and put it all together with ffmpeg and mencoder. that was on linux, now on windows i just use fraps to record it and then use virtualdub to compress it to an uploadable size. it's working surprisingly well all things considered (i have onboard audio/video on this laptop which really kills me)

i see you saw the video i upped, hit me up on hurleur forums and i'll send you the patch, assuming this patch of yours works with wavetable lookup to some extent, all you need to do is use the lookup that you have for the audio array scale that to 0-1, then run it to the video patch which just rescales it by multiplying it times the number of frames in the video. that's the gist of the rearrangement, the blur and luma offset were done manually but you can also scale those to any values you want
