I ran into a related quirk last week. I had a different SRW-5500 that did not have the FC, Format Convert, board and it did not output 29.97Psf even with the system set to 29.97 Psf. The PB display indicated Psf on the front panel but unlike the previous SRW-5500 I had worked with it did not output a true Psf signal according to the BMD Ultrascope. My guess is either this deck had older firmware or the FC board enables the true Psf output. I'll have to check with Sony for the scoop. Who needs file based workflows when you can get just as confused with a good ole tape machine. ;-)

This tells me the Avid doesn't know to put the proper wider broad pulses that signify Psf over I. The deck was happy anyways. Interesting that the Sony HDW-1800 did not output 29.97Psf when it was set to 29.97 mode but rather 59.94I. Gotta love the consistent inconsistency of all the new formats. ;-)

Toggling the project to 1080I/59.94 shows the proper interlace clean fields. Even outputting to tape at 29.97P the Psf (fields) are clean and it looks fine. What is puzzling is that both my Panny LT-BH2600 and Ultrascope monitoring the avid output show the output as 1080I 59.94 no matter what the project format is set to. I know electrically the 59.94I vs 29.97P signal are identical except for the broad pulse structure in the vertical intervals. I figure that is how monitors and things like the ultrascope or an aja Kona3 show you if the signal is 59.94I or 29.97Psf etc... Why doesn't this get reflected on the Avid output HDSDI. I would expect my monitor and ultrascope to show the output as 29.97Psf when I have the Avid project set to 1080P/29.97 and 59.94I when I toggle the project. I can see an indicator

I've tried disconnect house black to the avid and running it on internal sync but all my monitoring still says 1080I/59.94. Is the Nitris DX not adding the proper vertical sync info to the HDSDI signal or are both my Panny Monitor or Ultrascope mis reading the signal. I use to use the Kona3 control panel to check this stuff but don't have one available. Can anyone with and ultrascope and or a Panny LT-BH2600 confirm that they can in fact properly sense and display 59.94I vs 29.97 Psf as part of the on screen display that pops up on the panny monitor when you switch sources to tell you what the signal is. Since both the tape machine

The only thing that reflects a difference is the top status line on the Sony deck depending on which mode it is set in to make the recording. It's getting on tape correct but what's really happening here. Any suggestions for trouble shooting further are welcome.
