Hi Steffen,
When scheduling audio for fractional frame rates, applications will often follow the SMPTE audio cadences, e.g. for bmdModeHD1080p2997 at bmdAudioSampleRate48kHz this is defined as 8008 samples in 5 frames, distributed as 1602, 1601, 1602, 1601, 1602.
For the DeckLink API, as long as the required number of audio samples have been scheduled for the frame being prepared for output, playback will be correct, regardless of how the application scheduled those samples (e.g. 1600,2 / 801,801 etc.)
Cheers,
