Magic Music Visuals

This is a fairly frequently asked question - but tricky to search for on the forum unless you know how to phrase your search.

Here's one from last year: https://magicmusicvisuals.com/forums/vi ... 64&p=11523

How about "if floor(value*100) = 130"

That image is created using a striped mask of the built-in waveform. The waveform is also highly blurred before using it as a height map then the mask is also used as a texture on the height map.

Globals are fantastic and have a number of important uses. Primarily they are used to synchronise the same value across multiple nodes. They are also excellent for documenting important numbers (e.g. iterations, BPM, counts, timers etc) and, Using them in the very powerful expressions as variables. ...

Sure, the texts were all two word phrases containing the word dragon, e.g. Chinese Dragon etc. As far as I can tell, the concepts are broadly mixed between scene changes and even persist longer. I haven't experimented enough to know the optimal phrases yet - working on it.

Embrace the concept of sub-scenes. Combined with globals and organised with folders they are effective at simplifying and organising workflow.

With a combination of scale and offset you can create almost any range.

Use a ramp then an invert on the pixelation level. Adjust the value of the ramp to change the speed of the transition.

The visual is using a PyTorch ML script called Illustrip and the music is composed by AIVA. There are better scripts but I don't have the hardware to run them.

By "scene caching" do you mean the time taken to load a scene? It's an important metric, but I can't figure out how it could be quantified. I meant 'Keep Scene in Memory' which has an impact on scene loading times - possibly affected by GPU or PCI version or memory speed - but your right,...

Sounds like a memory leak. Are you using any plugins? Perhaps your machine is just running our of memory?

I would guess that since the dots increase the more keys you have, that your alpha isn't completely clean.

I've never ventured into MDK but in the header it says:

// Instantaneous values of the mapped params your module uses
const float *paramValues;

Which suggest that these are float values, not strings. Only float (module) parameters can be instantaneous.

Looks like a lot of work went into this - some interesting elements and I like the pace and number of changes.

If your sure that the data your referencing is string data then just cast the value.

char* id = (char*) userData->paramValues[1];

'char*' instead of 'char'?

You can get around this by installing a virtual midi port and assign each physical device to several virtual devices, thereby allowing you to control multiple apps with one device.

Yes, that totally works, thanks Eric. I tested several scenarios: chases, alternating loops, dance offsets and others. For folks to set this up... On the VideoFile start parameter add these modifiers: Increase 1.0 (that's the scene timer) Expression: if ( x = 0, offset, 0) where offset is the delay ...

Any SceneInput node will be blank without an input. You can composite this over any other 'default' content which will remain visible until the SceneInput is connected. If the input is opaque, the 'default' content will be hidden. It will cost you in processing though.

Is this what you mean?

These are gross simplistic examples for very short loops.

But even for longer video, an offset to show different parts of the video e.g. offset dance moves, chases etc..

A small suggestion for the video file related nodes. In the VideoFile node, there is a start parameter from which the video starts and, when the video ends, will loop it back to that start value. I can imagine several use cases for a similar parameter (called e.g. "offset") that initially ...

You are right, it should be a simple thing.

Try a different audio file/format? What system are you on? Is mute [M] on? Is the play button pressed when there's no audio file? Can other apps play your music? Magic should output audio to the default audio device - is that configured correctly?

In Magic you can't adjust the relative volume of audio files. Although sources have gain, that only effects the visual. While you can mix audio outside of Magic and drive visuals via a virtual audio cable, you can't render videos that way. The only way is to use a program intended for mixing audio a...

No, but the playlist has a random feature, the layer modules can be randomised, and you can use the keyboard to change the file.

Make sure there are no 2D effects between the media and the rotate. All the transforms will not clip media. All 2D effects will clip the media to the current resolution. It is better if your media dimensions is greater than or equal to the diagonal dimensions of your output resolution. That way you ...

You don't need to use expressions though of course jameseye is correct with his. You can use any oscillator modifier (Sine, Triangle or Ramp) which all go from 0 to 1 and back. Then scale it by 0.02 to bring it in the range 0 to 0.02. Then Offset by -0.01 to shift the values in the range -0.01 to 0....

To 'subtract' one polygon from another use the Blend(Difference) then use the combined image as a mask. You can invert the mask by using Invert on the image.

In the future, please try to explain more fully the result you're trying to achieve, including more relevant forum post titles. That way we can help you more efficiently and will...

You can use anything as a mask.

Another intriguing scene you've created. It looks like some of your lasers should come in front of the dancers. Also, your EQ effect should have some perspective. I would prefer more going on too. It is a great idea though, and well executed.

Kudos for using the default Magic shader!

Try some demo projects. If you can't see anything with audio files, the built-in mic and your Scarlet then it is more likely your scene that is wrong.

Use a B&W image with the Mask node.

I've thought this would be handy myself occasionally +1

You're using two keys on you OBS webcam (chroma AND luma) - is this necessary? If you have well keyed video, you probably don't want to also blend. If you do want to blend, then the Blend node takes two inputs - you only have one. If you're capturing game footage with OBS and composing it in Magic, ...

Put your spout senders in their own scenes (e.g Hose-A and Hose-B) and attach a scene input to each sender. Keep Hose-A and Hose-B in memory and use them in all your other scenes (not stored in memory). Perhaps that should maintain the Spout connections and save you some GBs. Does this work for you?...

I like the space laser scenes. They would be more atmospheric to have more change to the planet atmosphere or surface and landscape which, I think, would make it more intriguing and add a layer of movement. Even simply change the angle of the land.

In OBS, for "Spout2 Capture" properties, set 'Composite mode' to 'Premultiplied Alpha'.

Make sure "Send alpha Channel" is enabled, assuming you're using spout.

From the manual: If a new entry is selected while a Crossfade or Additive Dissolve is underway, the new entry's scene will appear immediately; the transition will be canceled.

Variables may be practically unwritable, but you can assign values. For example, this will 'compile' in an expression: var z1 ; z1 := 5; if (x > 3, z1, x); This code creates a variable and separately assigns a value and does return 5 when x > 3. You can't write to globals, but I've found that being ...

Well, that's subjective, one person's too much is another's not enough!

You can always attenuate overlays and fx with transparency, mix module, blend modes, masks etc. It also depends on what your objective is.

Magic can be a box of delights or a Pandora's box - the fun is deciding which to open.

Trivially..

Yes, should be no problem.

There isn't a specific keyed, blurred or noise - it all depends on your source content and the style of flames you're after.

Put your continuous video in its own scene (e.g "longvid") then include that scene in every other scene. This will make the long video play throughout all the other scene changes.

Good luck with recovering your files.

No midi for this but I know what you mean about variable environments - the gain can be used to temper the audio as it was intended but it can also be used to destroy a scene if your not careful, but also give very different scenes, depending on how they're set up. https://magicmusicvisuals.com/down...

The 'Increase' will start from 0 when the scene starts. There's no way to pause or delay this. You can only restart the scene or reset the node chain. Even if nodes are bypassed or powered-off the Increase will continue. The only way to delay it is to offset the move further off the screen. You can ...

Oftentimes I want to insert nodes earlier in a sequence.

It would be useful to be able to select all nodes after a selected node w...
