Animation details
:
•
Animations are always displayed as a sequence, static frames cannot be selected
•
The maximum animation duration depends on the logo image size.
For example an animated logo image with a 10% raster size overlaid on 60Hz signal
is limited to a maximum of 10 seconds
•
Sequence capacity of 10,000 pixels maximum.
(approximately 44 Seconds for 150 x 50 Pixels at 60 Hz)
•
Interlaced video standards will treat each image of the original sequence as a single
field of the resultant animation. Frame to field conversion is performed by simply
removing those lines which should not be present in a particular field.
•
Animations will not be displayed in the logo selection box until the upload is complete
•
Animations will always start from the first frame of the sequence on 'Take'
•
Animations can be loaded as a sequence of still images or a sequence of moving
video (e.g. MPEG) files. One animation can be created from a sequence of files of
different file types so long as the image size is the same in each file
•
Animations are displayed at the output-side frame rate. If an animation is designed to
be played at 50fps but the current output standard is 59Hz it will play out faster than
designed.
Logo Control Setup
:
•
Logo Selection
: Select a logo for the current channel:
Select a logo by clicking on the logo name. The selected logo is highlighted. Click on
None Selected
if no logo is required for the channel.
•
H Position
: Set the position of the left edge of the logo image from the left of the
screen as a percentage of the screen size. Adjustment range 0 to 100%.
0 = left edge of the logo is at the left edge of the screen.
•
V Position
: Set the position of the lower edge of the logo image from the bottom of
the screen as a percentage of the screen size. Adjustment range 0 to 100%.
0 = lower edge of the logo is at the lower edge of the screen.
•
Transparency
: Set the transparency level of the logo from 0 to 100%.
100% = Invisible
•
Pre-Shaped
: Sets the key format to Pre-shaped when checked and Linear when
unchecked.
When the key format is set to Pre-shaped it is possible to simply cross-fade between
background and foreground. This changes the edge shape of the logo but the
pre-processing of the key means that the final result will be the intended edge shape.
When Pre-shaped is not checked a linear key format is used and cross-fades
between back foreground and foreground so the key follows the shape of the
logo.
•
Take
: Enables and disables logo display on the video output of the channel.
When Take is checked the logo is displayed on the video output of the channel.
•
State
: Displays the state of the selected logo. Typically this would be “Logo load
complete”
•
Logo Selected
: Displays the name of the selected logo.
•
Delete
: Deletes the currently selected logo. If the logo is in use this action will fail.
