+Thanks for your inquiry. The minimum number of frames that you can preroll
+for scheduled playback is three frames for video and four frames for audio.
As you mentioned if you preroll less frames then playback will not start or

Regarding the bmdDeckLinkConfigLowLatencyVideoOutput flag:
There can be around 3 frames worth of latency on scheduled output.
When the bmdDeckLinkConfigLowLatencyVideoOutput flag is used this latency is
-reduced or removed for scheduled playback. If the DisplayVideoFrameSync()
-method is used, the bmdDeckLinkConfigLowLatencyVideoOutput setting will
-guarantee that the provided frame will be output as soon the previous
+reduced or removed for scheduled playback. If the DisplayVideoFrameSync()
+method is used, the bmdDeckLinkConfigLowLatencyVideoOutput setting will
+guarantee that the provided frame will be output as soon the previous
frame output has been completed.
