Unless you are just using the recording feature of Resolume to make video clips, at some point you will want to route the video from Resolume out of your computer, hopefully to a really big screen.
Before you can configure the outputs in Resolume you need to set up the displays in your computer's operating system before you run Resolume, in order for the displays to be available in the Output menu.
First make sure the display or projector is connected to your computer.
Windows - To set up the displays in Windows, open the Display panel in The Control Panel. On the settings tab make sure you have at least 2 displays visible and active. This is usually called having the two screens in 'extended desktop' mode.
Mac OS X - Open the Display Preferences in System Preferences via the Apple menu. Then on the Arrangement tab make sure 'mirror displays' is turned off. Now you have two separate displays on your computer.
Now start Resolume and checkout the Output menu. The Fullscreen and Windowed options enable you to select which of your computer displays the main Resolume output should go to and whether it should fill the screen (usually the best option if your are using a video out from the computer) or windowed (sometimes useful if you are using an external scan converter).
You can remove the output by selecting the Disabled option.
If you are spanning your output over several projectors or screens, Resolume provides a flexible way to control which part of your composition goes to which output.
To access these settings, select the Output > Advanced menu option.
You will see a window that lists the active screens on your computer down the left hand side and shows a rectangle representing your composition on the right hand side.
To setup a screen, select it on the left hand side, and choose which output of your computer it should use on the right hand side. This way you can assign the correct screen to the correct output very quickly when working with multiple outputs.
After setting up the outputs correctly, you can tweak the output further by using slices.
Each screen can have one or more slices. By defining a slice, you can control what part of the composition it will contain. This way you can define that the left hand side of the screen will always go the projector on output 1, and the right hand side should go to the projector on output 2. But you're not limited to dividing it vertically, or even halfway. You can select any part of the composition you want to account for different output resolutions and aspect ratios.
You can select a slice by clicking it on the left hand side. You can then use the Input Selection panel to resize it and drag it around in the right hand panel.
Tip! Hold down CTRL (CMD on a Mac) and drag in the Input Selection area to quickly create a slice where you are dragging.
You can also type precise numbers into the boxes at the right if you need the output to show a precise part of the composition. You can even use math to let Resolume do calculations for you. Verrrry handy! Let's say you want to make a slice exactly a third of its width, all you need to do is type ”/3” after the width setting and press return.
Right clicking a slice will also reveal a drop down with some useful slice setting presets.
In Resolume Arena, the Advanced Output Settings has many powerful additional features.
Each display can be configured in two modes: Input Selection and Output Transformation.
Input Selection works the same as for Resolume Avenue.
Additionally, you can tell the slice to wrap around the composition for 360 degree panoramic projections.
In Output Transformation you can apply screen warping, which means you can adjust the position or geometry on the final output. This is useful for projection mapping the output to an irregularly shaped surface, or when aligning multiple projectors for a spanned output.
This mode again is made up of two submodes: Edit points mode and Transform mode.
In Edit Points, you can select a slice on the left and then pick up corner points and drag them to a desired location. You can add or remove points on the right, as well as choose between linear or bezier interpolation. Bezier interpolation adds bezier handles to the points that allow you to curve the edges. Also you can show a grid to help the aligning process.
When you have a single point selected, you can fill in precise values or nudge the point with the arrow keys or controls on the right.
In Transform you can change the position, scale and rotation of the entire slice in the output. This is useful if you want the same part of your composition repeated on two differently sized displays or if you need to adjust for a pixelmap on a LED wall.
You can hold down CTRL on a PC/CMD on a Mac to quickly switch between Edit Points and Transform modes. Also you can right click for some useful preset settings.
If at any point you get confused during the process for which part of the output is going to which monitor, you can troubleshoot by identifying the displays by type and number, which will show in both the interface and the output. Also you can display a test card to calibrate and align your projectors.
Tip! If you are using a lot of slices, masks and crops for a project, you can quickly rearrange their order by dragging them up or down in the slice stack. You can even drag them to another display.
Besides adding displays and slices, you can also add masks and crops directly in the Advanced Output. Masks and crops allow you to hide parts of the output, without distorting it.
A crop will cut off all pixels that are outside of it. A mask will cut out a part of the image, effectively creating a hole. You can have as many crops and masks as needed.
Masks and crops can have an arbitrary amount of points. By default they are created as squares, but you can make them into triangles, circles, stars, hexagons or in the shape of that weird stain on the wall in the attic.
Double click the outline to add a point at that location, double click a point to remove it.
A crop can be turned in to mask and vice versa using the drop down on the right.
Also, you can apply edge blending to any slice. This will help you blend the output where two projectors are overlapping, by gradually fading out the area where they overlap.
In order for edge blending to take effect, you need to have two slices cover the same part of your composition. This overlap should mimic the physical overlap of the projectors on your surface.
For best results, a minimum of 15% overlap is recommended. Then you can turn on edge blending for each slice in turn. Resolume will automatically blend the edge in the middle, but you can still control the edge by refining the following three parameters:
Power: This control the slope of the edge blend curve. The higher this number is, the steeper the curve will be in the center of the fade area. Luminance: This control the brightness of the centerpoint of your fade. This allows you to further adjust the slope of the curve. Gamma: This is the overall brightness of the fade area.
For detailed info on the edge blending process, check out the paper by Paul Bourke: http://paulbourke.net/texture_colour/edgeblend/
Since projectors project light, they can never project true black (black actually is the absence of light). Rather they project a very deep grey. So where two projectors overlap, in the areas that should be 'blacked out' by softedging, they will project deep grey on deep grey.
Since projectors work in additive colour space, this causes the problem to accumulate, and the result in the overlapping area will be an even lighter grey. The black level compensation is to make up for this difference, by allowing you to make the non-overlapping areas slightly brighter.
Also you can adjust the brightness and contrast of each output, to fine tune any difference in luminosity that can't be solved by adjusting the projectors or screens themselves.
Tip! If you are using both a LED screen and a projector, and the LED screen is blowing all the other lights in the venue away, you can decrease the brightness on the LED screen, while still having the projector at full power. Or just leave everything at maximum, and give the audience a tan with your visuals.
It's possible to switch between different screen setups. Using the dropdown in the top left of the Advanced Output window, you can save and select different setups.
This is especially useful when you are playing weekly gigs at different venues that each require a specific setup. Using the preset system, you can just select the appropriate setting from the list, without having to recreate it again.
This also means that your output setup is not tied to a certain composition. You can use different setups with the same composition, and use different compositions with the same setup.
It also allows you to share presets between computers. After saving, the preset can be found as an .xml file in the Resolume documents folder:
Mac: Users/~/Documents/Resolume Avenue-Arena 4/presets/screensetup/
PC: C:\Users\[username]\My Documents\Resolume Avenue-Arena 4\presets\screensetup\
You can copy this file to the same folder on the other computer. After restarting, the preset will be available from the dropdown.
Tip! Sharing presets also works between Mac and PC!
