audio/video granulizer test rendering, august 30th

puredata.info - puredata.hurleur.com
this was all rendered in realtime and recorded in fraps - in this test of my pd audio/video granulizer i stumbled across a neat trick that got much smoother visual effect compared to the last video (the graffiti/colored wall one). this one features a short black and white video loop from some free video loop package i found, and the beat sample is a typical amen variation. the sequencing is constant, 64 bars looped with a pretty basic rearrangement. it starts 180 bpms and remains so for a while, even when the playback starts to slow down (since it's the audio playback slowing down, not the sequencing). a bit into it i slow the sequencing down, then at the end bring it back up to 180. the granulizer settings i just tweak out a bunch, but what i love about this patch is you can sequence out the rearrangement so even if the granulizer is all over the place, it's still adhering to a sequencing so there's defined hits according to your pattern. then on top of that, although this setting was tweaked by me as i played and don't have any control over any audio parameters, is the luma offset effect, which creates a quasi 3d effect... plus a new trick i figured out which creates a serious smooth rendering compared to my other videos.
the granulizer audio-wise runs into a simple lowpass/distortion patch and that in turn runs into a small reverb i made with a handful of delay lines. the reverb was independently tweaked from the video the same way the 3d effect was tweaked by hand and not connected to anything, BUT the idea is to just have these values have ONE control value, and then scale this one control value (which is a range between two values) to the two controls you want it to, those being an audio control parameter and the other being a video control parameter. the only reason i didn't do this in this video is i just wanted to test the new video technique, so i needed that value independently tweaked, otherwise until you lock down a good scale/range for each audio/video parameter you risk ending up with a crappy sound when you have a good video result, or crappy video when you have a good sound.
essentially the master goal is to have a large slew of audio parameters to tweak in realtime at your will, and then have a corresponding video parameter for each audio parameter, each scaled just perfectly that a change in one will have a sensible result in the other. once you have this across the board it's a matter of sequencing, although the sequencing's the easy part. also this is just between one single granulizing sequencer and one video loop and fx technique. the next step is coming up with a logical scheme for it all to be laid out in an easily controllable AND assignable manner, as well as add a shit-ton more instruments and video tricks. anyways now that i told you my secrets i have to find you and eat your soul, nothing personal

[darkvvulf]

is this patch available anywhere?

[pidipid]

@darkvvulf PM me, it's actually a combination of a couple patches

[pidipid]

also - mono audio, i forgot about that, reverb is a mono output

[SPKaa]

@2:01 - what tripping too hard feels like, but it happens in all five senses

[erikopnemer]

I've always wondered what the output of a video granulizer would look like. I wonder no more.

I never want to take your drugs.

thats cool man

[nimrodskid]

batshit.  awesome.

[grinick]

Wow, this is ridiculous.

[toxonic75]

christ, this is awesome!

1:58 to 2:21 is also interesting.
