Le¹Mix

General information

“Le'Mix” - software solution that dramatically expands the capabilities of standard equipment used for technical support of public lectures, presentations, lessons, reports, conferences, etc.

The usual (without using “Le'Mix”) scheme is that the demo video stream containing media materials (ppt-presentations, slides, videos, etc.) is fed from the computer directly to the demonstration device (projector, monitor or interactive whiteboard). The organization of broadcasting (recording) requires an operator (s) with a video camera, an editor and, accordingly, a broadcasting and recording system.

When using “Le'Mix”, a demo video stream, a signal from remotely controlled PTZ video cameras (one or two), as well as sound from a microphone are fed to the inputs of a computer on which “Le'Mix” is installed.

“Le'Mix” allows:

• to combine a demo video stream and the video from PTZ cameras in different ways by the "picture-in-picture";

• operatively add title elements (screen, titles, subtitles, timers);

• control of the PTZ cameras;

• Control of the overall level of sound;

• output resulting video on a demonstration device;

• broadcast video to the network (for example, via “YouTube”);

• record video on a hard disk or portable device.

One operator easily handles all these tasks by “Le'Mix” - thanks to a convenient, simple in mastering and intuitive interface.

“Le'Mix” can also be used separately (without additional equipment) for recording / broadcasting an individual video lecture. You can read about it in the section “additional features”.

Interface

The interface of “Le'Mix” contains the following panels:

• menu

• Schedule(Title list)

• Output (Preview)

• Output streams

• Title

• Compositions (PIP's)

• Input streams

In the upper right corner of each panel (except for the menu) an icon is located , when clicked which opens the options dialog box related to this panel.

Menu

Contains the icons “New Project”, “Open Project”, “Save Project”, “Full Screen”, “Edit”, “Exit”.

Schedule (Title List)

Contains a list of texts for title elements. The selected line becomes the text content for the next title elements. If the title element is active when the content changes, then the changes will take effect only at the next show. To select a line - use a single click. To switch to the text editing mode, double click on the corresponding text fragment. At the top of the panel are icons for permutations, adding and deleting lines, saving to a file, and loading from a file.

Text content for the main splash screen (Screensaver 1) is assigned in the settings dialog of this panel (icon ).

Output (Preview)

Contains the preview image of the resulting image, as well as the icons (enables / disables control of PTZ cameras), (turns on / off the sound), as well as the “slider” of audio controls. In the output settings menu, you can configure the audio input from a system device, such as a sound card. You can also assign a background image from a file on disk.

Output streams

Contains on / off buttons for recording to disk, Internet broadcasting, displaying on a monitor (TV, projector), as well as sound. Setting the output modes is carried out in the dialog box of this panel (icon ).

Titles

Contains four types of title elements call buttons. The selection, creation and editing of title elements is carried out in the settings dialog box of this panel:

Compositions (PIP's)

The Compositions Panel (PIP's) panel is a set of four options for arranging PIP windows and their contents, which are available for quick access. The contents of the PIP window can be assigned to one of the input streams: “Presentation”, Camera1 or Camera2. To implement a specific PIP window layout template, just click on its “preview” in the “Compositions (PIP's)” panel. To change the composition of a set of available layout options, edit existing templates, or create new ones, use the settings dialog box of this panel:

You can save (add) created or edited template options to the general collection for future use.

Templates from the collection are available from any projects.

Input streams

The “Input streams” panel contains “preview” icons for input streams. To display the stream in full screen, just click on the corresponding icon. To configure each stream, you need to call the dialog box by clicking on the appropriate stream "wheel" . Camera dialogs allow you to customize the control of PTZ cameras.

Controlling PTZ cameras

To enable the control mode of PTZ cameras, you need to “click” on the icon in the upper right corner of the output stream preview panel. Turns are performed by moving the mouse cursor with the left button (Drag-and-drop) held down on the preview screen, and “zooming” (zoom in / out) using the horizontal “slider” at the bottom of the panel or the mouse wheel when you hover on the window preview of this panel. It is possible to “save” the two “wound” states of each PTZ camera (in the output streams panel) and subsequently return to them with one click.
