Go to Options, Preferences to the Video Device tab and change the Sync Offset until you are back in sync. It can be adjusted from 0 to 12 frames. (default is 4)

I don't think he is referring to audio/video sync. I think it is just the video sync (correct me if I'm wrong) IF you are running a dub from one deck to another (usually professional decks like Betacam) you need to have a sync line going from the playback deck to the record deck otherwise you get the annoying black line that works its way down the screen.

If it is an audio sync issue then yeah, just adjust the offset, but if it is video that won't help.

I've seen wierd sync issues with the Canopus when feeding signal to a Tekronix WFM (TVM710), and I told Canopus about it awhile back- this is their problem. The Sony DVMCDA2 as well as DVcam decks do not exhibit this problem.

Are you feeding the beta deck svhs or composite from the ADVC? SVHS is my guess. Does composite make a difference? Is the deck sync feeding the monitor?

Thanks, Jsnkc. I read "sync" and my first thought was A/V sync. And I see how it COULD be off going through that many devices. I wasn't thinking of VIDEO Sync.

SonicEPM, I'm feeding composite to the Beta. I have a hunch that if I get a video splitter and run the outputs in parallel as opposed to series they'll resolve as they seem to do this ok when I direct patch to the beta and to the monitor. I'm going to give this a try today.

My next problem now is that when I ouput to tape (from the Tools menu) something seems to happen to the signal so that I lose video level and the beta doesn't get a solid picture; weird color shifting, etc. This may be a Canopus limitation but I'm curious if anyone else has had this problem or if it might be my signal routing error. This only seems to happen when I use the render output to tape function from the menu.

Thanks for your helpful responses!

If you have DV camera that supports pass-through (just about all of them do this), try using that instead of the Canopus as a test:

DV from 1394>camera 1394 in>camera svideo out>deck svideo in

any difference?

Hi Gallois,

I too dumb to BETACAM as final output. I had the same problem. I found that applying the color correcter filter to the output at the last step before rendering (the computer rgb to studio rgb preset) brings the levels legal for BETACAM). Rendering is a bit longer though, but levels are right.

Hey videogram, yeah I always use broadcast colors when dumping DV source footage to Beta. If it was filmed in beta though it's usually fine.

Canopus dubbing to Beta update:

Still getting weird color shifting, alternating blue and red exageration every 10 or 20 seconds. So somehow the Beta cannot get a solid signal or cannot lock properly when the ADVD-100 is ouputting the full quality rendered signal with audio. It records fine when I just send the "output to monitor" signal (without audio). The Beta deck also records combined video and audio just fine when I send it from the DVCam composite output.

So does this sound like a problem with the ADVD-100? Has anybody else had this problem?

SonyEPM: Unfortunately my DV Camera doesn't seem to allow for video pass-through.

"It records fine when I just send the "output to monitor" signal (without audio). "

Sound like a Canopus issue. Can you feed that known-good "output to monitor" video to the deck and loop through the deck via EE to the monitor? Audio will need to be patched in separately of course, easy enough.
