I'm not sure what you mean... It should be pretty easy to chain effects, just plug an output into an input

But something that's potentially confusing is that there are four different datatypes you can have in your composition. They are differentiated by the colors of the little input/output circles.

The datatypes are:

1) Value (grey circle). This is just a number, and you can connect it to almost any parameter input.

2) Image (purple circle). This is a 2D matrix with any amount of channels (e.g. in addition to RGB, you could have alpha, and Z-depth, and x/y/z normals). A one-dimensional image can also be used to represent any kind of linear data - e.g. the Audio Input node outputs an audio waveform as a 1D image.

3) Geometry (blue circle). This datatype can contain 3D points, polygons, and Bezier shapes. But right now, there aren't any really useful nodes in Edo that use this datatype..! I'm going to do at least an OBJ loader eventually

4) Drawing (green circle). This datatype actually represents a native GPU 3D rendering operation. The 3D Layer and Floating Lines nodes are examples of nodes that output this kind of data.

In the Convert effect category, you can find nodes to convert between most datatypes. For example, the Get Pixel node can be used to obtain a value from an image. The Slate node can be used to convert a drawing into an image. And so on...

Is this any help? I know, the app _desperately_ needs a manual and some useful tutorial files...

Thanx! I'll study with this info beside me ...

[Mbazzy]

Btw, could you also explain how the audio input works 'cause Edo doesn't seem to see my audio - input ...

How do you define the inputs ? Shouldn't Edo see the Inputs of my G5 automagically ?

[Mbazzy]

Pauli,

Really having a blast with Edo!

A little AV tidbit I made up with it can be found here (Edo+FreeFrame+Imovie) - http://zed.cbc.ca/go.ZeD?POS=1&CONTE...nt&user=mbazzy (If anyone deems it worthy of a comment please be my guest ;-) )


Any chance that a "recorder" module will be added to Edo, so that one could record/sample a more performance oriented piece with active parameter tweaking ?

Had a few crashes with Edo. Do you want the crashlog for each "meltdown ?"

[Mbazzy]

Pauli just released an update of Edo .

From the Edo site :

New in Edo Release 1.0.8:
(5 Mar 2005)

* Directional Blur and Gaussian Blur nodes

* 3D Camera node: lets you manipulate a drawing input in 3D space

* Get Pixel Color node: gets a single pixel from an image

* Isolate Color node: creates a matte from a color in the input image, has width and softness controls for inclusion of nearby colors

* Completely revamped preview functionality for image nodes.
Now you can have multiple previews open, easily switch between the original and output images, zoom and pan inside images, and pick colors. Nodes can access the color picker. For a practical example, try the Isolate Color node: open its preview, switch to the original image, pick a color (it's in the Tools tab), and press the "Get Color from Color Picker" button in the Node Inspector.

* Blue/Green Linear Key node. This is a keyer optimized for blue and green screen images. It operates in a linear chromacity color space. The parameters are not very intuitive, but it produces more useful results than Isolate Color, which does basic RGB keying. Read the "More Info" help text for more details on how to use this node.
To get a good key, you can of course combine this node with Isolate Color - use a Comp2 node to combine the two mattes.

* The Curves node now supports CPU rendering in 32-bit floating point color. Its tonal curve is no longer limited to the 0 - 1 range, so you can now color correct high dynamic range images freely.

* The Levels node now supports GPU rendering

* The Linear->Device node now has a setting to disable the hilight softening knee

* Small UI tweaks, including horizontal lines in Curve Editor, and scroll bars for the Node Inspector in all modes (previously, the Export button could get hidden when inspecting a composition root)

* Pressing spacebar and dragging with the mouse inside the Composition Window now pans the view

* Miscellaneous bug fixes, including garbled output with some TIFF files, a problem with saving image sequences, strange output with the Gamma node, pixel aspect ratios not propagating across the composition, and more...

Due to internal changes, when you open a file saved with an older version, some nodes may default to a different quality setting than what you had specified (e.g. GPU 8-bit integer instead of 32-bit floating point). Sorry!

How do you define the inputs ? Shouldn't Edo see the Inputs of my G5 automagically ?

It uses the system's default input device, which you can select in System Preferences > Sound. At least my Powerbook offers the choice between line in and built-in mic.

This is the only Mac I have, and I don't own any external audio devices either, so it's possible that the audio input only works with the Mac's built-in input. I just have no way to test it in other configurations, unfortunately...

[Mbazzy]

OK, will have to see with eg. a drumbox attached to the inbuilt input of the G5 , if it sees the input.

With nothing attached physically , it shows "no inputs" in the info panel of the audio source module ...

Will also test if it will see the SoundFlower virtual audio i/O when i install those.



Btw, for anyone interested , some more NooB freshman beginners AV footage ...

Just to give an idea of the way we're heading ... Consider it more than an exercise ...
This is the first longer AV clip by undersigned ... Minimal tools , hopefully bigger effect ...

Hi Mbazzy,
actually the "no inputs" just means that the node doesn't have any inputs (in other words, it only outputs data).

There's no controls for choosing your audio input, the node just uses the default system input and assumes that you'll set it in System Preferences to what you want (mic or line-in).

I've added a discussion forum to my site, you can find it in the Support section (http://www.anioni.com/edo/support.html). I think we should move this discussion there

Hi all,
I've updated Edo to version 1.0.9.

I guess the major new feature is the ability to nest compositions (use a composition as a source clip in another composition). The clip deck is a bit reworked internally, now you can finally put compositions in the deck. It should be less crash-prone too, because I fixed a serious old bug. (Sorry if it's still unstable for you...)

The new flow control nodes could potentially be useful for VJs too. With Switcher, you can switch between image inputs either manually, or driven by a value. With the Condition node, you can create boolean expressions (it has an easy iTunes-style interface). You could make some fairly complex behaviours with these simple tools, I think.

There's also new color adjustment tools, a 3D Matrix node, plenty of bugfixes and performance improvements... Details are in the release notes.

I've also finally made some almost useful example files. They're on the download page. Here's a movie of the new 3D Matrix node:

One of these days I'll start writing the user's manual

Hi,
I've updated Edo to version 1.0.9b. This version is mostly about bugfixes, but there are a couple of new features. Full details can be found in the release notes.
