A new recording can be started any time (if a free buffer is available), even if a
recording is currently running. The switch to the new recording buffer will be done
without delay, no frames will be lost.
7 Stop recording, this switches the current recording buffer into “used” mode so that
it can be played back.
8 Select the Playback Mode which can also be either “Loop” or “Once”. Loop will
resume playback at the start of the buffer once the end is reached, Once will stop
playback when the end is reached.
9 Select the Stop Mode which defines the behavior of the playback output if no
playback is running. Can be either of:
• Live: Show Live image (just like the live outputs)
• Black: Show a black image
• Test Pattern: Show a test pattern
10 Start Playback of the selected buffer. Only enabled if a buffer is selected in the
buffer table. Starting playback will enable the playback controls (see point 12 and
following).
11 Stop Playback, this will switch all buffers into “used” state and switch the playback
output into the mode that is specified by the Stop Mode (see point 9).
12 The seek bar shows the current frame position in the frame buffer that is being
played back. You can drag the seek bar handle to seek to a new position.
13 The skip buttons can be used to skip 1 or multiple frames at once (perform a
relative seek). They can be used while playback is running or while it is paused.
14 The mark bar shows the current mark-in and mark-out positions. The playback of
the buffer will loop between the mark-in and mark-out position. Drag the left or
right mark handle to adjust the positions.
To play back a part of the video that is not inside the marked area either re-adjust
the mark positions or manually drag the seek handle (see point 12) out of the
marked area.
Moving the mark-in position behind the mark-out position will reset the mark-out
position to maximum and vice-versa.
15 Alternatively to dragging the left mark handle of the mark bar (see point 13) you
can also click the “Set Mark In” button to place the mark-in position.
16 Reset marks to minimum (frame 1) and maximum (last frame in buffer).
17 Alternatively to dragging the right mark handle of the mark bar (see point 13) you
can also click the “Set Mark Out” button to place the mark-out position.
18 The playback speed controls allow you to setup the playback speed. You can
either use the speed bar to precisely setup the speed or use the x0.5, x1, x2, x5
and x10 hotkeys.
18 Pause or resume the currently running playback.
