Converting to HD-SDI

what refresh rate are your screens?
and your video input?
and catalyst frame rate?


there arent any driver issues with phoenix - there is no quicktime driver-
any issues with phoenix installation need to be referred directly to active silicon- there arent any software/driver issues-

Simon's method is best. I have done this method dozens of times.

Its time consuming but it's the best and only way to resolve issues with capture cards. (Also the same method for the Phoenix Cards with the exception of the driver file.)

I have still seen this happen regardless of any troubleshooting. I am dealing with this very issue in fact in a nightclub. Fortunately I am the only one who notices but it still drives me nuts.

My speculation is electrical noise and subtle phasing problems which cause the digitizer to perceive a drop. I can't confirm this but nothing else makes much sense.

Thanks for your input Richard... glad to see you getting in on this one.

the source is NTSC
catalyst is set at 30fps
Refresh rate is 60.02 I think (1024x768) for the output to led controllers

Based your comments it would be better to lock the playback to some division of the refresh rate I assume?

source ntsc. so somewhere in the region of 29.97Hz ( though not necessarily accurate )

is this a pro camera or an cheap camera setup?

which LED product is/was it?

dmx or dvi?

suggest as a potential first step you try setting frame rate to screen div 2 and see whether it gets better or worse

its related to the problem of how to play back the 23.98 movie we had before-
its the same kindof deal-

NTSC video camera signals dont fit neatly into dvi/vga/LED controller refresh rates.

I know I'm jumping in a little late here, but I can also recommend the TVone boxes. One thing to note however, is that at least on the 2355, while it can genlock, you need to genlock based on your output format (i.e. tri level for HD, Blackburst for SD) While on an imagepro, you can use black to genlock and HD signal. Not a huge deal, but one you need to know if you are using them. There are actually a few devices out on the market that let you take a blackburst or trilevel signal in, and use that as a reference out for the other type of sync. that are fairly cheap.
