MUAN is a support tool for the creation of frame-by-frame animation. Using a camera, it receives digital images, with which animations can be created. The basic principle for the creation of an animation with MUAN begins with the capturing of an image by the user. The image that will be captured is shown on the image panel. After capturing a certain number of images, the user can reproduce his animation, as well as edit it. Finally, the animation can be saved in an AVI format and loaded whenever the user wants.


Main Commands

Image Panel

MUAN’s central panel, where the images are displayed. It works in two different modes:


Memory

Displays images from the memory (constructed animation).

Camera

Displays images sent by the camera, in real time. In this mode, the word CAMERA will be visible on the top left hand corner of the panel.

Memory/Camera Selection

Determines if the images displayed on the panel come from the camera or the animation itself (memory). In the “Memory” mode, it indicates that the images displayed on the image panel come from the animation. In the “Camera” mode, it indicates that the images displayed in the image panel come from the camera.


Shortcut: CTRL+/


Important: If the camera is not connected to the computer or is turned off, the application will display a message and enter (or continue in) the “Memory” mode.

Capture Button

Captures the next image received by the camera, inserting it in the animation, in the position following the current image.


Shortcut: \

Frame Duration Textbox

In the Camera mode, defines the duration of the captured frame. For example, a 2 frame duration indicates that the next captured frame will last 2 frames when the animation is created.


In the Memory mode, defines the duration of the current frame (which is being displayed in the image panel). Just type in the duration you want and press ENTER.

Go To Textbox

Places the animation in the desired position and displays it on the image panel. The user must insert the number of the required captured image and press ENTER.


Important: In this case, if the program is on Camera mode, it will automatically switch to Memory mode.

Current Capture Text Output

Indicates the number (position) of the current image (capture).

Current Frame Duration Text Output

Indicates the duration of the current frame.

Current Frame Text Output

Indicates the number of the current frame.

Indicates the number of the current frame.This number is calculated in relation to the duration of the previous captures.


Tip: If the main panel is in the “Memory” mode, the current frame will be displayed in the image panel.

Total Capture Text Output

Indicates the total number of images captured for the animation.

Total Frame Text Output

Indicates the total number of frames in the animation.

This number is calculated is relation to the duration of all captures.

File Text Output

Indicates the name and the path of the current file (where it is saved).


Tip: TipWhen the name of the file is in red, this means that the last modifications in the animation have not been saved.

First Frame Button

Positions the current frame on the first frame of the animation.


Shortcut: HOME


Important: This operation switches the application to “Memory” mode, if it is not already in that mode.

Previous Frame Button

Returns the position of the current frame in 1 position.


Shortcut: <


Important: ImportantThis operation switches the application to “Memory” mode, if it is not already in that mode.

Stop Animation Button

Freezes (stops) the execution of the animation.


Shortcut: PAUSE


Important: For this fact to be observed, the “Memory” selection must be activated in the “Memory/Camera” Selection and the animation must be playing. If this is not the case, clicking this button is useless, so nothing happens.

Play Animation Button

Executes the animation.


Shortcut: CTRL+ENTER


Important: This operation switches the application to “Memory” mode, if it is not already in that mode.

Next Frame Button

Adds the position of the current frame by 1 position.


Shortcut: >


Important: This operation switches the application to “Memory” mode, if it is not already in that mode.

Last Frame Button

Positions the current frame on the last frame of the animation.


Shortcut: END


Important: This operation switches the application to “Memory” mode, if it is not already in that mode.

Section Button

Activates the option of playing just a section of the animation. The beginning and the end of the section must be specified in the Beginning and End boxes, respectively.


Shortcut: CTRL+R

Beginning Textbox

Determines the position where the animation begins to play. If the box is blank, the animation will be played from the first frame.


Tip: In the “Memory” mode, use the Beginning Button to define the beginning of the section as the current frame.

End Textbox

Determines the final position of an animation being played. If the box is blank, the animation will be played to the last frame.


Tip: TipIn the “Memory” mode, use the End Button to define the end of the section as the current frame.

Loop Button

Activates/deactivates the option of playing the animation continuously. When activated, it continuously plays the animation from the beginning, as soon as it reaches the end.


Shortcut: CTRL+L

Copy Button

Copies an image or a section when selected into the memory.

Paste Button

Pastes an image or section that is stored in memory.

Inverted Paste Button

Pastes a section backwards.

Flip Button

Flip ButtonActivates/deactivates the “Flip” operation, which alternates the display of the last image of the animation and the image that is being received by the camera. It is possible to control the speed of the flip through the slider.


Shortcut: CTRL+F


Important: ImportantIf the program is playing an animation, it automatically stops when flip is activated.

Transparency Button

Activates/deactivates the Transparency operation, which applies a transparency and superimposes the last image of the animation with the image that is being received by the camera. It is possible to control the percentage of transparency through the slider.

Full Screen Button

Makes the application go into full screen, i.e., the screen of the monitor is completely filled with only the image panel. To return to the normal screen, use the ESC key.


Shortcut: ALT+ENTER

Remove Button

In “Memory” mode, removes the current frame, if the operation is confirmed. An animation always needs at least one frame. Therefore, when the last frame is removed, the Opening Frame is automatically inserted into the animation, becoming the current frame.

Image Size

The Image Size is defined by the selected camera, or can be altered by the user.

The Image Size is defined by the selected camera, or can be altered by the user. Note: The alteration of the image size should be done with caution, since once the image size has been altered and saved in preferences, MUAN will always initialize with this size chosen by the user, and not with the size defined by the camera. To return to the size defined by the camera, the user must unmark the Override option and click on the Save button again.

Note: The image size is only altered when the user clicks on the Save button. When the Save button is clicked on, MUAN closes down and the user must restart the application.


Opening Frame

Image used by MUAN, usually as the first frame of the animation, since all animations must contain at least one frame. It works as a tablet for the animation.


Default Duration

Defines the default duration of the captured frames, i.e., the duration that will be used in the capture when the user does not define a duration in the Duration Textbox.


Automatic Save

Activates/Deactivates the option in which an animation is automatically saved by the system, after a defined time period.

    File: Defines the name of the file where the animation will be automatically saved.

    Time: Defines the time period (in seconds) that the application takes to automatically save the animation.


Connection Type

The camera selection depends on what platform is being used. On Mac OS and Windows, there is only one type of camera. On Linux, the user can choose between DV, DC and V4L (standard).
