TC on SDI

[Mark Raudonis]

Steve,

An SDI signal contains BOTH timecode and audio within the signal… all on one cable.

Your BlackMagic card should easily decode that info upon digitizing.

Hi Steve,
If you conect your BMDL to a video desk you can get the TC through the RS422 conexion and also inserted in the video signal (VITC. The BMDL allow you to keep this VITC, but I don’t think any shoftware cam make use of it).
In the times of old the TC was generated by the recorder or by an external TC generator. This was recorded in an audio track (LTC) or in the top lines of the image (VITC).
But want you want to do is to reccord the video produced by your camara before being recorded and in this case I don’t think you got any TC available. I’ve been recording video to the CPU from a DVcam directly from de composite video-out, but I can not get any TC in because the one generated by the camcorder is recorded on the tape and only accesible by FireWire. What I meant is that when you have your camara in stand-by its output a video signal but the TC generator it doesn’t works untill you hot REC. I don’t know if the new camaras can work different and output a TC signal when they are in stand-by, and that this TC can go in the SDI out.

Steve knows this
FCP will not currently read TC over HDSDI-

Just wondering if anyone had any type of magical work around. It seems as though as soon as you don’t have deck control, all TC functions are lost. On capture now, it should still read the TC through the RS-422 connection but that is gone too. Apple is completely asleep on this one. One of the biggest tools in the pro world is TC and we don’t have it.

The media management problems are enough to make ya crazy.

Thanks again.

Steve,
Can’t you get it through the “Blackmagick Desk Controlaplication’ that can with the BM drivers? It supposed to contol a video desk seting IN and OUT points based in the TC.

i’m not a daily FCP user, but isn’t a cheapo LTC to 422 converter (a lot of them around for around 50 bucks…) capable of emulating a 422 deck?
Or, just hook up an old VCR with extTC in enabled, in rec mode to do the conversion?

If all fails, i can write an app. that locks the current time of the CPU to the LTC of the camera,
should be a work around. (have a look at my LTC reader, it’s on my site)
