Hi Nicolas,
It is a requirement when working across multiple cards that each output is locked to reference for Synchronised Playback to start successfully. This check is made by the DeckLink driver and will error if one or more devices in the synchronised playback group is not already locked to reference. Without reference input locking, there will be no relationship of frame timing between outputs on different cards, and so synchronised playback would not work.
When all output devices are on the same card, for example with the DeckLink 8K Pro, it is possible to start synchronised playback without needing to lock to a reference. This is because all outputs enabled with same frame rate will already share the same frame timing.
Regards
Cameron
