+\r
+Thanks for your inquiry. The minimum number of frames that you can preroll \r
+for scheduled playback is three frames for video and four frames for audio. \r
+As you mentioned if you preroll less frames then playback will not start or\r
+playback will be very sporadic. From our experience with Media Express, we \r
+recommended that at least seven frames are prerolled for smooth playback. \r
+\r
+Regarding the bmdDeckLinkConfigLowLatencyVideoOutput flag:\r
+There can be around 3 frames worth of latency on scheduled output.\r
+When the bmdDeckLinkConfigLowLatencyVideoOutput flag is used this latency is\r
+reduced or removed for scheduled playback. If the DisplayVideoFrameSync() \r
+method is used, the bmdDeckLinkConfigLowLatencyVideoOutput setting will \r
+guarantee that the provided frame will be output as soon the previous \r
+frame output has been completed.\r

+\r
+Thanks for your inquiry. You could try subclassing IDeckLinkMutableVideoFrame \r
+and providing a pointer to your video buffer when GetBytes() is called. \r
+This may help to keep copying to a minimum. Please ensure that the pixel \r
+format is in bmdFormat10BitYUV, otherwise the DeckLink API / driver will \r
+have to colourspace convert which may result in additional copying.\r
