Rendering and Realtime
Realtime and the Effect Preview
On the Timeline, the above-mentioned effect types are indicated in the Slices (the numbered segments
above the Timeline) by means of defined colors. In this way, the system provides information on the
effect preview or playback behavior:
Slices above the Timeline
 Green -
These segments will certainly be played back at the full frame rate (for example, PAL: 25 fps/
NTSC: 30 fps) because either hardware effects are applied or the Slices have already been ren-
dered (fps means frames per second).
A green Slice indicates that a render file was created for this segment. The file is used to play the
Slice.
 Ye l l ow -
These segments may
jitter when played back (i.e. played back at less than the standard fps rate),
meaning that frames are dropped. Realtime software effects are always “yellow” because the sys-
tem cannot supply exact information before the actual playback.
A yellow Slice always indicates that the system will attempt to play the segment in realtime, even it
has to reduce the frame rate (drop frames). Audio remains synchronous.
Preview is possible in the Master Viewer video inlay and via an analog monitor output (optional);
but not via IEEE/DV out.
 Red -
These segments must always be rendered.
Where no rendered data yet exists, a gray exclamation point on a black surface becomes visible in
the inlay as soon as the Playline touches the section not yet rendered.
A deep, intense red indicates a render problem. Remove the effect(s) that caused the problem.
 Gray -
Everything that is not green, yellow or red, i.e. normal video and graphics, is played back at the
full frame rate.
