What is a Sequence?
The DVE presets represent timelined sequences of user defined keyframes.
Each keyframe contains all the information for that particular frame e.g. size
of video, position, border information, etc. The DVE interpolates (morphs)
between the keyframes over a user defined number of frames. Another term
for this is tweening, because the card calculates the ‘in-between’ frames.
There is a limit of a total of 25 keyframes which are shared between both
channels of video. The following is an example of a 3 keyframe sequence
which lasts over 7 seconds.
Saving the Sequence
Whilst working with a sequence, all your
changes are saved in a ‘workspace’. If you
load a new sequence or power off the unit,
the workspace will be reset. Pressing either the play forward arrow or play
backwards arrow plays the sequence stored in the current workspace. In order
to commit the changes permanently you have to type in the desired sequence
number and click the ‘Save as sequence no.’ button.
