‘To New’ Delay Duration
If Wipe is the selected video type or CrossFade is the selected video or
audio type, this is the number of frames of delay after the transition begins
before the transition to the new source begins.
If FadeFade is the selected video or audio type, this field is disabled (grayed
out) as it is not applicable.
‘To New’ Duration
Once the transition to the new video or audio source begins (regardless of
type selected) this is the duration, in frames, from the beginning of the new
source transition until the transition to the new source is complete.
Looking at the configuration for the “Aud before Vid” transition in
Figure 278 above, we can see from the graphical representation that the
entered parameters define a transition with the following characteristics:
• The video transitions as a FadeFade which means the old source fades
out before the new source fades in.
• The audio transition is a cross fade between the old source and the new
source.
• The video transition does not begin until 20 frames after the transition
is initiated.
• The audio transition begins 5 frames after the transition is initiated.
• The audio cross fade transition from the old source to the new source
takes a total time of 15 frames (1/2 second in 60 [59.94] Hz standards).
• The audio transition is complete before the video transition begins.
• When the video transition begins, the old source fades to black in 15
frames.
• The video remains at black for 15 frames.
• The new source fades in over 15 frames.
• The total time for both the audio and video transition is 65 frames (2
seconds and 5 frames in 60 [59.94] Hz standards).
