Flash XDR Tips & Tricks

Hi Aaron:
Yes, the XDR seems to have a very good, very accurate clock generator inside it. I appreciate CD for spending what must have been the extra coin for a higher quality clock chip generator circuit. I've seen allot of video devices which feature TC generation as an additional function, which have really unclean, inaccurate, swiftly drifting time code output at a weak line level signal. The XDR is SMPTE spec as far as I can test it.

Stand by for more feature uses of the XDR. Producing a tested and recorded CF card TC reference with SMPTE Bars and reference audio tone is preferable, because you can record several different types of format TC references on multiple CF cards, thus being ready to drive whatever device running in whatever format from the secondary HD-SDI output of the XDR.

Hi Friends:

You can drive the Flash XDR from some digital audio multi-track recorders via the external LTC input, such as the Aaton Cantar X-2. The advantage of the wired LTC signal method is a guaranteed solid TC reference lock between your audio and video.

* For some shooting situations, having a hard wired TC reference to the XDR is impractical. For such situations I recommend the wireless Jam-Sync use in 1080 59.94i shooting mode. Also, it is advisable to re-jam sync often (Every 30 to 45 minutes max)
