How to deal with PushButton OFXParameterType?

Dexcon wrote on 8/26/2022, 7:35 AM

Is there some way to even get value from PushButton parameter type from OFX Effect??

Which OFX effect/s are you referring to and which Vegas Pro version are you using?

You've posted under the Scripting topic so please let the forum know which Script you are getting this PushButton parameter type issue with.

Vegas Pro 18

Im trying to manipulate BCC Scatterize effect; Its not specific to this effect but any effect that have a button field

This is probably an issue that you may need to take up with BorisFX as it relates to BCC coding - https://forum.borisfx.com/ - and any other 3rd party plugin provider that has this issue for you.

@julioimolesi I'll make a tutorial on this which will be out in a couple of weeks. In short, you don't "access" a "PushButton". A button is something you "push". There are no values to change and no values to access. Instead, you change other values (if needed) and then "push" that button. So the question becomes - how do I push the button? The answer is simple:

ofxparm.ParameterChanged();

Call "ParameterChanged()" on that push button and it will - push the button. Please see the tutorial September 5th on my YouTube channel or via my website. I'll provide more details there.

@jetdv I dont really need to Push the button, I just need to set the filename value.
This button opens a File Selection dialog, I just need to change this value

jetdv wrote on 8/26/2022, 10:26 AM

@julioimolesi, Unless that file name is stored somewhere else you can access, you can't get that. All you can do is "push" the button from the script. You can't see a dialog that button opens. Is that file shown in some other box on that screen? Perhaps you could access that box. Either way, you have to have manual intervention to select that file.

If you CAN see that file name in another parameter, you might be able to just write the file you want to that parameter.

I don't have the BCC plugins so I don't even know what the shown options are on that screen. A screenshot might help. You might run this to see all of the available parameters.

Can you explain in more detail what you're are trying to achieve through the script?

julioimolesi wrote on 9/5/2022, 9:49 AM

@Jason-Clement I want to automate the BCC Scatterize plugin settings, enabling option Beat Reactor and selecting the Audio File:

I already tried to save and load the plugin preset, but the audio file information was not saved in the preset file :/

Former user wrote on 9/5/2022, 12:16 PM

@julioimolesi Hi, It saves the external file info in the preset in VP19,

Did you rename the preset after you added the External file?

You can't modify the Default preset, you have to create a new one by renaming the Default & saving using the Save at the end of the preset name box.

julioimolesi wrote on 9/5/2022, 1:29 PM

@Former user Do you know where preset files are saved?

Maybe its possible to modify it and load by the script..

Former user wrote on 9/6/2022, 2:50 AM

@julioimolesi No sorry i don't know how to load a preset by a script, @jetdv is better to answer that,

Why do you want to load the preset via a script?

Jason-Clement wrote on 9/6/2022, 7:14 AM

@julioimolesi One thing to remember is there are two different types of presets. There are Continuum's own presets which are stored in C:\ProgramData\BorisFX\Continuum. And there are the Vegas host presets which are stored in Documents/OFX Presets.

It appears that the Vegas Host presets to retain the audio file information, but the audio info is stored in an encoded binary format as part of the ParamID.900 custom param, not as a simple text string so there is no easy to edit its contents. And the Continuum presets do not appear to store the beat reactor settings at this time - which kind of surprises me. I wonder if that is a bug - something we'll need to look into. Unfortunately I don't see a way to readily edit the audio file via preset manipulation.

jetdv wrote on 9/6/2022, 7:18 AM

@julioimolesi, @Former user Here's how to do that:

PlugInNode effects = myVegas.VideoFX;
PlugInNode thisEff = effects.GetChildByUniqueID("{Unique ID of the effect you want to load}");
Effect eventEffect = new Effect(thisEff);
vEvent.Effects.Add(eventEffect);
eventEffect.Preset = "Name of the preset to load";

Line 1 - get the list of all effects from VEGAS

Line 2 - find the specific effect you want to use

Line 3 - Get that effect as a new effect to be added to the event

Line 4 - Add it to the video event

Line 5 - Set the preset you want to use

jetdv wrote on 9/6/2022, 7:29 AM

And here's the tutorial showing how to "push" the button from a script.

Former user wrote on 9/6/2022, 9:28 AM

@Jason-Clement @julioimolesi 👍 I see now, i think,

Vegas saves the preset no problem with the external file info, the Sampler corner points positions & all the other settings/parameters.

But the Boris fx preset save/load option only saves the parameters, not the external file info, & in the preset box it still shows 'No Preset' even tho one has been saved & loaded.

@jetdv Thanks, I've never got involved with scripts... maybe one day 👍

julioimolesi wrote on 9/7/2022, 10:49 AM

@Jason-Clement

I found the file, but its encrypted, i will try some tricks later if I cant bypass using @jetdv tutorial

Jason-Clement wrote on 9/7/2022, 12:30 PM

@julioimolesi It's not actually encrypted, but it's a binary data format - not human readable strings - so not really editable through scripting unfortunately.
