Which DeckLink cards do support Clock Timing Adjustment?

PostFri Jul 22, 2022 2:34 pm

I've been trying to find out a DeckLink card that supports BMDDeckLinkSupportsClockTimingAdjustment.
I am using the following piece of code:

Code: Select all
hr = m_pDecklink -> QueryInterface( IID_IDeckLinkProfileAttributes ,
                                    ( void ** )&m_pDeckLinkProfileAttributes );

if ( m_pDeckLinkProfileAttributes != NULL )
{
   BOOL   supports;

   hr = m_pDeckLinkProfileAttributes -> GetFlag( BMDDeckLinkSupportsClockTimingAdjustment ,
                                                 &supports );

   if ( SUCCEEDED( hr ) )
   {
      if ( supports )
      {
         m_DecklinkClockTimingAdjustmentSupported = TRUE;
      }

   }

}


I am using SDK 11.7.
I tried using drivers version 11.7 and 12.4.
I tried the cards Intensity Pro 4K, Extreme 4K, Extreme 4K 12G.
Neither one seems to support that feature.

You may be better off opening a support ticket. The forums are for community discussion and although sometimes BMD employees do drop in to answer questions there's no guarantee they will.

Hi Altug,
Thanks for contacting the Blackmagic developer support team.
The output clock timing adjustment is supported by the following DeckLink products:

• DeckLink Duo
• DeckLink Quad
• DeckLink Duo 2
• DeckLink Quad 2
• DeckLink 8K Pro

Could I understand the reason for this request for your application, in case there is potential for workaround solution?

Kind Regards
Cameron Nichols
