I was instead thinking of some 4:1:1 formats not supported by the video hardware. You are correct, 1080PsF 25 4:2:2 8-bit should work. Is this Nitris or Dual-Link? With Nitris, you need a proper Tri-level 25PsF reference. For Dual-Link, make sure that you are locking the picture on the SDI video input. Both hardware work differently on input. But they

Jayanta has a valid question. If the incoming HD stream is not YCbCr 4:2:2, capture will not be possible. The same would be true if you capture the same video uncompressed. You might need a signal converter.

Glad it worked.

The information that you were looking for is posted on the Avid DS Support Center . The NVIDIA Quadro FX 1400 is just below the minimal 1500 requirement that allows DS to enable its viewer in real-time. But you can maybe try these suggestions from the Avid DS Training Edition page, and see if that works for the 1400 card.

In the Output Tool dialog, under Output Settings and Output Resolution, select instead Custom and enter 864 x 486. These values resize the 720 x 486 output to a 16 by 9 file output. 16 by 9 being an image horizontally compressed by nature in SD. True 16 by 9 only exists in HD.

Sorry, I forgot ONE important step... After you load the 50i clip on the 59.94i timeline, this clip will play faster due to the shorter frame rate. To correct this, you must apply a time effect and expand the clip to the required duration. Example: 59.94 x 60 seconds x 30 minutes (for a 30 minutes program) = 107,910 frames. Then you process this time

Not from the DS application itself. But you can use external equipment, such as the Teranex converter , to output at a different frame rate. If you have no access to such equipment, you can output the 50i sequence as an AVI Reference (it only takes seconds since you only write a reference to media in the DS storage), open a sequence using the required

Before you export the AAF or AFE from Media Composer, can you disable the secondary audio timecode? This should force the conform to use strictly the continuous timecode as the main time reference in DS. But to be more specific, do you mean that the audio timecode is being written in the DS clips properties? Or is the wrong TC used during media capture

But that question was not for Avid DS, am I correct assuming this?
