Mitti has various settings and preferences to output different kind of data.
Mitti supports fullscreen output on multiple displays, even with Corner Pinning and Edge Blending applied. You can find the Video Output Window in the Output menu. This window is where you can setup the output displays, and there should be always at least one screen added where Mitti can render content in fullscreen.
To toggle fullscreen rendering on/off, you can use CDM+F key combination or there is also a menu item in the Output menu.
The Video Output Window consists of 3 parts, discussed in more detail below:
The top part of the Video Output Window is where you can setup the key parts of your screens setup. A screen setup in Mitti is defined by rows and colums of screens, which is often represents how you place projectors and other displays physically, and also related to how Mitti will span content between displays and projectors if needed.
You can set the number of screens you want to use by either selecting an existing value - something like presets for common 2xWide, 3xWide setups, etc. - from the Screens: popup, or by selecting a Custom number of rows and colums of screen.
When enabled, Mitti will displays a Test Card on all video output displays which could be useful setting warping, edge blending and identify outputs.
By default Mitti duplicates to video content to all displays, but if you enable the Span Across Displays option, instead of duplication the content Mitti will span that across displays. This is the setting you should turn on if you are working with super-wide or super-height content with Matrox DualHead- or TripleHead devices.
With edge blending you can combine multiple video output to make one perfectly a single seamless image. Toggling on the Edge Blending Button won't has any effect however, its just enable you to use the screen-level edge blending settings.
The Screens View displays the screen object in your setup, and also gives you info about the layout of the screens as well as screen number and the resolution info. There should be always a Current Screen, which is drawn by blue and you can select it using your mouse or trackpad.
The Screen Settings is where you get finer controls for the Current Screen and apply settings like warping and edge blending.
You can select the corresponding screen with this popup.
You can split your current screen to smaller pieces with this popup, which is useful for super-wide and super-height content. The items corresponds to common settings. For example if you are outputting to a Matrox DualHead2Go, you can select which screen of the 2 to use.
The orientation of the screen, you can rotate the final output by 90, 180 or 270 here.
With the Warp View you can apply corner pinning - aka quad-warping - for the Current Screen, by dragging one of the four corner points. Mitti showing a checkerboard image here to represent the output within the screen bounds.
Mitti supports Linear and Perspective warping and with the Warp popup you can select which one to use for the Current Screen.
Perspective warping - the default mode - guarantees perspective-correctness, which is useful in the most cases, but cannot guarantee continuity because of the perspective-correctness applied, which could be problematic with edge blending.
Linear warping guarantees a continuous image across a split, but since it is not perspective-correct, it may distort images if higher warping applied.
The zoom ratio of the Warp View.
You can move the selected corner point here, by either setting pixel coordinates manually or by dragging the field's right side.
With the Edge Blending settings you can specify overlapping in pixel values as well as power - gamma correction - on each side of the screen that has an other screen surrounding.
Mitti supports playback of Audio Cues - as well as audio track of Video Cues-, and will route audio to your system's default audio device by default. You can set the sound card you need in the Audio Output Preferences which accessible either from the Outputs menu or from the Project Preferences.
Here you can set the Output Device, set the Master Volume. Output channel routing is also supported as well as setting Output Delay (ms) to fix latency issues introduced by other video gear.
All Cues will use these settings by default, but you can set different output routing and volume individually in Cue's Audio Output Preferences.
If the Extent Mono Files option is enabled, Mitti will extend mono audio to all channels and make it stereo or multi-channel.
Mitti can broadcast the video part of the Current Cue with Video FX applied to Syphon clients. This is an automated process, which means Mitti's Syphon server is always alive and will transmit data if there are Syphon clients connected - this means you don't need to setup anything to get Syphon output from Mitti.
The dimensions of Syphon output - the width and height of the output - will always match with the dimensions of the source material.
Mitti can transmit the video part of the Current Cue with Video FX applied to any Blackmagic Design Decklink, UltraStudio or Intensity device which supports outputs. You can enable transmission in Project Preferences by selecting your device as Output. This action will also build a list of supported output formats by your device to the Format popup.
The dimensions of Blackmagic output - the width and height if the output - will be matched to the Format you selected, so Mitti will down- or upscale on the fly to fit if the output dimensions does not match with the Current Cue.
Mitti's Blackmagic Output also supports the device's built-in keyer if present, so with the appropriate hardware you can play out graphics and overlays including an alpha channel (called key and fill signals), or superimpose the graphics over the incoming signal.
With multi channel output gear like the Ultrastudio 4K or Decklink Quad that have built-in keyer, you can set the Keying: mode to External in Mitti's Blackmagic Output Preferences to send two signals on two SDI outputs: one for fill, one for key.
With Keying: mode set to Internal the appropriate Blackmagic output gear like the Ultrastudio 4K will superimpose the graphics over the incoming signal.
Please note that transmitting to Blackmagic devices has not the same performance than a native video output from your graphics card (GPU), so that can result in increased latency and higher CPU usage.
Transmitting audio to Blackmagic devices separately currently unsupported, but you can set the global audio output to Blackmagic devices.
NDI™ by NewTek Inc., is a new technology for IP-based video production. With NDI Cues in Mitti, you can use any NDI output-enabled video application on the local network as sources.
Mitti can broadcast the video part of the Current Cue with Video FX applied to NDI clients if you enable that in Project Preferences. The NDI tecnology supports both YUV and RGBA formats, and Mitti will use YUV by default because most of the cases that is more efficient. However YUV does not support alpha channel, so if alpha channel is required, you can turn on RGBA transmission optionally.
The dimensions of NDI output - the width and height of the output - will always match with the dimensions of the source material.
Output audio with NDI is currently unsupported.
