. this is a test a module i wrote that modulates two different effects based on user selectable audio bands. i programmed in a high/low range for the effect parameter being modified to prevent the original video getting completely lost. the effect definitions (fxList[]) and modulation ranges (fxMod[]) are defined in Init() if you want to change/delete any of them.

. you can dial the audio band (0-22) and the effect or hit the 'random' button and it will choose two effects from the list (below) click 'reset' to turn off the effects.

. you will need modul8 v2.6 and os X 10.5+ for some of the core image (CI) effects and Pete's Plugins for the free frame effects.

. here's a video of me using the random button on 120 avFX (and misspelling 'origInal' ) - i did have trace on ~ 30% and sometimes the effect combinations don't work together very well (esp. the last few seconds). the source clip was originally created w/this module, then rendered to it's own file.

. the following is a list of fx i coded into the module and the parameter that's modulated :

(CI) Pixellate - Scale
(CI) Circle Splash Distortion - Radius
(FF) SpiralBlur - Layer Count
(FF) Kaleidascope - Source Angle Pro
(CI) Bump Distortion - Scale
(CI) Circular Screen - Width
(CI) Edge Work - Radius
(CI) Eightfold Reflected Tile - Width
(CI) Hexagonal Pixellate - Scale
(CI) Glass Lozenge - Radius
(CI) Glide Reflected Tile - Width
(CI) Hole Distortion - Radius
(CI) Kaleidoscope - Angle
(CI) Op Tile - Angle
(CI) Sunbeams - Sun Radius
(CI) Torus Lens Distortion - Radius
(CI) Triangle Tile - Angle
(FF) Posterize - Levels
(FF) Refraction - Cell Width

. please enjoy! any feedback/suggestions/code improvements appreciated!

Good work. Fun little demo as well.

This is so awesome. Thanx a lot

. more 120avFX noodling around

I'll check it out, it looks great, thanks a lot!

Nice work. Very useful module - thank you so much!

wow! what a great mod really well done!
i had often found that tiles/kalidascope kinda fx
were all or nothing , like you said
as nice as they are,they lost too much of the
original contents essence
but with a little tweeking and your fab mod
you can make some astounding effects

well done!

works really nice!!

very nice! fast access!

Bueno .nomad, I love this module.

I'm doing a couple mods on the fxMod parameters and i'm wondering if it's possible to have more than one? If so, what's the syntax i would need to use, i've just started reading up on python so i'm new to the methodology and still curious.

So far i've tried:
fxMod[19] = {'NAME' : 'Style', 'PARAMS': {'low' : 0.1, 'high' : 0.8, 'default': 0, 'type': 'real' } } : {'NAME' : 'Example', 'PARAMS': {'low' : 0.1, 'high' : 0.8, 'default': 0, 'type': 'real' } }

doubling
fxMod[19] = {'NAME' : 'Style', 'PARAMS': {'low' : 0.1, 'high' : 0.8, 'default': 0, 'type': 'real' } }
fxMod[19] = {'NAME' : 'example', 'PARAMS': {'low' : 0.1, 'high' : 0.8, 'default': 0, 'type': 'real' } }

trying to insert
fxMod[19] = {'NAME' : 'Style', 'PARAMS': {'low' : 0.1, 'high' : 0.8, 'default': 0, 'type': 'real' }, 'NAME' : 'Style', 'PARAMS': {'low' : 0.1, 'high' : 0.8, 'default': 0, 'type': 'real' }

to no avail.
Would i need to change something in the PeriodicalEvents(elapsed)? say:
if fxActive[0] or fxActive[1] :
to
if fxActive[0] or fxActive[2] :
maybe?

Thanks for the module!

. orion,

. yes, it is possible to modulate more than one parameter, but that would require some additional coding.

. the values for fxMod (the high and low values) and useFX (which effect that is currently being used) are set in MessageEvent()
. for example, if we use effect 5 -

fxList[5] = {'FILTER': '(CI) Circular Screen', 'PARAMETERS': {'Width': 0.385, 'Center Y': 0.5, 'Center X': 0.5, 'Sharpness': 0.565}}
fxMod[5] = {'NAME' : 'Width', 'PARAMS': {'low' : -0.2, 'high' : 0.6 , 'default': 0.4, 'type': 'real'} }

. based on the 120 avFX module - most of the work is done in PeriodicalEvent() -


. i have the two arrays of dictionaries (which i've since moved towards a single dictionary definition for effects ) that are associated by their index (5, in this case)

. fxMod[] - give the name of the parameter for the effect (called modName[0] above) -Width - and my high and low values. the above code calculates the range of values to be used and sets the value of that parameter.

. when doing effects, the basic flow is: update the effect values, clear the effects, push the new effect parameters into the effect -



. so, to answer your question (finally ) - if you were modifying the 120 avFX module, you could create another array - with the second parameter you want to modulate... .ie,

fxList[5] = {'FILTER': '(CI) Circular Screen', 'PARAMETERS': {'Width': 0.385, 'Center Y': 0.5, 'Center X': 0.5, 'Sharpness': 0.565}}
fxMod[5] = {'NAME' : 'Width', 'PARAMS': {'low' : -0.2, 'high' : 0.6 , 'default': 0.4, 'type': 'real'} }
fxMod2[5] = {'NAME' : 'Sharpness', 'PARAMS': {'low' : 0.1 , 'high' : 0.6 , 'default': 0.4, 'type': 'real'} }

. then add code into the topmost block i quoted to adjust the second parameter (Sharpness in this example)

. remember the 'NAME': part in fxMod isn't arbitrary, it must be a parameter in the effect definition. for some effects, like Pixellate - you might only have one parameter you wish to change -

fxList[0] = {'FILTER': '(CI) Pixellate', 'PARAMETERS': {'Center X': 0.5, 'Scale': 0.075, 'Center Y': 0.5}}
fxMod[0] = {'NAME' : 'Scale', 'PARAMS': {'low' : 0.0, 'high' : 0.2, 'default': 0.075, 'type': 'real'} }

. so, if you did the fxMod2[0] method, you might set the name to 'NONE' so it will be ignored...

fxMod2[0] = {'NAME' : 'NONE', 'PARAMS': {'low' : 0.0, 'high' : 0.2, 'default': 0.075, 'type': 'real'} }

. then the above code could be changed to


. (basically - i just typed that in so there might be a minor typo or formatting issue)

. fxActive[0] and fxActive[1] are just True/False values to let the system know if they need to update the values or not. i figure it saves a few CPU cycles to not keep updating an effect that isn't currently active.

. let me know if you have any questions
