Preferences

The preferences panel can be accessed through the application menu or the keyboard shortcut ,

General

Windows

Layout - Allows you to select between the Single Window Preview layout and the Multi Window Preview layout (which splits the main MixEmergency window into three independently resizeable windows).

Opacity - These controls set the opacity of the main application windows. This can be useful if you need to monitor another application while using MixEmergency.

Forward keyboard events - When this option is checked MixEmergency will forward any keyboard events (not including short-cuts used by MixEmergency) to the external controller application. This can be useful if you don't want to switch between the applications.

Disable conflicting shortcuts - When this option is checked MixEmergency will disable keyboard shortcuts that conflict with the application currently controlling MixEmergency.

Effects

Automatically load effects - Enables loading of previously saved effects when media is loaded.

Automatically save effects - Enables saving of the last used effect preset per media.

Display

The Display preference panel allows you to control aspects relating to the output of MixEmergency.

Output

Quality - This adjusts the quality of the rendered output level. If you're experiencing low frame rates on full-screen then you may need to lower this setting.

Scaling - There are four types of output scaling: Fit, Letterbox, Zoom and Stretch.

• Fit - This adds black bars either horizontally or vertically to fit the full video into the output. The aspect ratio of the media is maintained.
• Letterbox - This adds only horizontal black bars to the media. Cropping may occur at the top and bottom of the screen. The aspect ratio of the media is maintained.
• Zoom - This will scale the media so that the entire output screen is filled. Cropping may occur at the edges of the screen. The aspect ratio of the media is maintained.
• Stretch - This stretches the media to fit into the dimensions of the output screen. The aspect ratio of the media is not maintained.

Arrangement - Controls the arrangement of panels on the output window.

• Mix - This option is the default and will display the mixed output of both channels.
• Left, Right - This option displays the left and right channel beside each other in the output.
• Left, Mix, Right - This option displays the left, mix and right channels horizontally beside each other in the output.

Enable Frame Blending - The option enables frame blending for videos, resulting in smoother video when scratching at slower speeds.

Enter full screen on startup - This option automatically activates full screen mode when the application launches. This will only occur when an external monitor is detected.

Flip Horizontal - Flips the output image along the horizontal axis.

Flip Vertical - Flips the output image along the vertical axis.

Enable Color Correction - Enables basic brightness, saturation and contrast controls for the output.

Brightness - Controls the brightness of the output.

Saturation - Controls the saturation of the output.

Contrast - Controls the contrast of the output.

Preview

Aspect Ratio - This sets the aspect ratio of the preview views. You can choose either None, 4:3 or 16:9.

Update Rate - The update rate of the preview views can be lowered using this control.

Transition

Transition

Reverse MIDI fader - This reverses the direction of any MIDI control assigned to the Crossfader.

Smooth fader - This enables Crossfader smoothing.

Random Transition includes - Use this to choose which transitions will be selected from when using the Random transition.

Auto-fade

Auto-fade duration - This sets the duration of the auto-fade control.

Auto-fade Hot-key - This can be used to assign a global hot-key to the auto-fade button.

Stopping media triggers Auto-fade - Stopping one channel's media (e.g. pulling backwards on your external vinyl control) while this is enabled will cause MixEmergency to trigger an auto-fade to the opposite playing channel. This is useful when you don't have access to a MIDI controller or mixer.

Fader cut distance - Allows you to adjust the fader cut distance for the crossfader.

Use External Controller Crossfader - Enables the use of your External Controller's (e.g. Scratch Live) crossfader.

Use External Controller Upfaders - Enables the use of your External Controller's (e.g. Scratch Live) upfaders.

Use External Controller Cuefader - Enables the use of your External Controller's (e.g. Scratch Live) cuefader.

Contour

Enable - Enables contouring.

Crossfader - Adjusts the contour of the crossfader between slow and fast.

Upfaders - Adjusts the contour of the crossfader between slow and fast.

Use External Controller Contour - Enables the use of your External Controller's (e.g. Scratch Live) contour.

Plug-ins

The two tables on this panel allow you to select and reorder the plug-ins that appear in your effect and transition lists.

Advanced

The settings on the Advanced preference panel are recommended for more advanced users.

Cache

The main slider in this window controls the amount of memory MixEmergency will allocate for caching video frames. Please note that MixEmergency will automatically decrease the size of the buffer if there is not enough memory available.

Display debug buffer views - This option will cause small buffer displays to be rendered above the channel preview views. These can be useful for viewing how well your computer is decoding video if you experience poor performance.

External Control

The pop-up menu allows you to select the default action when an unlinked audio file is loaded.

Lower full screen window level - This option lowers the window level of the output when full screen. This can allow other windows to display on top of MixEmergency. This is not recommended for general use.

Synchronise Output to Screen Refresh - Turning off this option may result in better performance, but will result in poorer image quality.

Loop Media longer than 1 minute - Selects whether to loop videos longer than one minute in length.

Delay Compensation

Delay Compensation allows you to compensate for any delay in video or audio in your system so that your video and audio will always appear in sync.

Enable - Enables Delay Compensation.

Delay Time - Controls the offset for the delay compensation.

Syphon

"Syphon is an open source Mac OS X technology that allows applications to share frames - full frame rate video or stills - with one another in realtime."

These settings allow you to toggle output via Syphon to other Syphon enabled applications.
