SDI on playback at DVinfo.net

Bob Thompson · February 3rd, 2007, 05:25 PM

I am a bit confused on the SDI terminals during playback of tape.

Is it possible to playback an SD tape and get SD SDI out of the jack that I could then connect to a DigiBeta recorder.

Is it possible to shoot in HD mode and downconvert (in camera) to SD and then get SD SDI out the jack, which could then be connected to a DigiBeta recorder.

Thanks for the help

I believe that what you want to do is possible.

I attempted to find the answer in the manual, but it was not perfectly clear.

Pages 100-101 seem to indicate that you can do it, but you will have to set the menu options properly as discussed on Page 101.

I have not tested this myself.

The main question, in my mind, is whether the HD-SDI/SD-SDI's output is downconverted in the camera. There is an option to lock the HD-SDI/SD-SDI output to SD-HDI only. Since this option is available, I assume that a downconverted signal is available at the SDI output.

Hi, The following are the menu settings required for the SDI out put from hdv tape to a digibeta recorder through the jack pack.

When the camera is in manual record mode ensure that:
in the signal setup part of the menu that the 'SD Output' is on and that the 'SDI spec.' is set to SD locked.

The switch to vcr playback mode:
again, signal set up...
'playback standard' - auto
'sdi output' - on
'sdi spec.' - sd locked
'hd down convert' - on

This setting works for me to play live out to a digi recorder. you then connect your sdi lead and timecode bnc to the digi deck.

I have also used the reverse of all these settings to play hd-sdi out live into a ds nitrus machine. Have to say was really impressed with both results. Excellent camera.

note: make sure the digi is switched to input video rather than ref.

cheers,

sorry if I don't get this but does this mean that I don't need to have my camera connected to the computer to get a 4:2:2 signal? I can record to tape and then playback to get 4:2:2 through the HD-SDI? that the 4:2:2 signal is stored to tape but can only be recieved through SDI?

No. The tape will only hold 4:2:0 HDV material. While the SDI output do send a signal from the tape, there is no magic way to get 4:2:2 back again. However some claim there is some processing on the SDI out that does make the image look better than captruing via firewire....although that is hard to believe completely.
