The “
Output Mode
” flag should be set to match the content of the video within the clip:
Field VI
or
Field
— either of these output modes should be selected for those clips with “field-based” video content (i.e. clips which
were originally shot with field-based video cameras). The “
Field VI
” mode should be selected if the given clip will be played with
slow motion or will be frequently paused when playing out the clip.
The vertical interpolator will help to eliminate “vertical hopping” during slow motion playback, and will help to eliminate “jagged
edges” when paused on a still image of field-based content.
Frame
— this output mode should be selected for those clips with “frame-based” content (i.e. clips which were originally shot on
film, or shot with frame-based video cameras—or clip that were created completely within computer graphics programs).
The “
Frame
” output mode provides the best resolution for such frame-based content, especially during slow motion or paused (still-
frame) playback.
The “
Play Repeat Mode
” flag determines whether the clip will be loaded and played with a repetitive playback cycle or not. The defined
play repeat mode is automatically activated whenever the given clip is loaded into a play channel.
OFF
— any time the given clip is loaded into a play channel, the play repeat mode is turned OFF by default and the “Normal Play” (
) button is activated. This flag is used if play repeat cycling is not desired, or if play repeat cycling is to be controlled from an
external control device such as third-party hardware control panels or vision mixer (switcher) controllers.
Loop
— any time the given clip is loaded into a play channel, the “
Loop
” ( ) play repeat mode is turned ON by default. With this
flag enabled, when the clip is played from the starting point, the clip immediately seeks to the defined “
Play Repeat IN
” timecode
point within the clip, and continues to play forward to the “
Play Repeat OUT
” timecode point.
When this OUT point is reached, the clip automatically (and seamlessly) seeks to the defined “
Play Repeat IN
” point, and play
forward from there again. This cycle will repeat for as long as the clip is playing.
Loop To
— any time the given clip is loaded into a play channel, the “
Loop To
” (
) play repeat mode is turned ON by default.
With this flag enabled, the clip can be played from the starting point through the defined “
Play Repeat IN
” timecode point within the
clip, and continues to play forward up to the “
Play Repeat OUT
” timecode point.
When this OUT point is reached, the clip automatically (and seamlessly) seeks to the “
Play Repeat IN
” point, and play forward from
there again. This cycle will repeat as long as the clip is playing. You can exit the loop mode by clicking the “Normal Play” button (
).
This “
Loop To
” play repeat mode is typically used when playing animated graphics which have a “lead-in” portion at the beginning
of the clip, then has a cycling component somewhere within the middle of the clip; and upon a user command, will play an “exit”
animation on the trailing portion of the clip.
