Mastering directly to Pioneer PRV-LX1 DVD recorder?

[Thaxter Clavemarlton]

I’m going to guess that some of the problem comes from the DVD having no TIMECODE or PRE-ROLL.

An edit system uses those functions for feedback to know what’s happening with a deck (if its rolling, etc.)

Since the DVD unit likely does not “send” anything like this back via RS422, the edit software doesn’t know how to handle the commands.

Rig up a separate room remote for the unit like many home theaters have. You can adjust volume and change tracks on a unit that’s in another room using a remote. You could probably hit REC from the edit suite using something like that.

Not sure the RS-422 would work correctly since there is no “pre-roll” for that unit.

Our DVD Recorder is in a separate room as well, but all I do is back up the timeline into black, hit Play, then walk out and hit REC on the DVD Recorder. Since we always include the Slate, no need for a “precise” start time since they’re just client reviews. Never have had a problem here in two years of using the recorder and like you said it’s light years faster than encoding a disc.

Hi Tom,
I don’t understand how to control a DVD desk through RS 422. As long as as I remember to control a device with RS422 you need a TC signal (proffesional VTRs) or at least a CTL (Contol Track Line) that is aidio-like track used and recorded by all the video-desks (from the 2′ to the VHS).
But in a DVD I do not see any of those ways to be contoled from a external machine.
Sorry for my short technicall language.
Cheers,
rafael

Hi

your not the first to try this. pioneer states that their rs422 interfeace is to Control a tape deck, not be controlled for editing….

THAT BEING SAID

you should be able to master to tape, which does not require preroll or editing capabilities like edit to tape. (we old guys call this “crash recording”) and i believe FCP can send a “roll in record” signal down the 422 to your device

under “audio video settings” is a tab for “Device Control Presets”. You can duplicate an existing preset, such as Sony RS422, and edit the settings. I see a check box for “auto record during PTV”. by experimenting with these settings you should be able to make a preset that works. Dont forget to duplicate the settings to keep the original preset safe

you could also edit your show to tape (assuming you have a vtr like that) then control the VTR from the Pioneer, insuring accurate starts and stops AND freeing you to edit while the discs are being made!

hope this helps

you said you have an avid? i believe Avid has the ability to “emulate” a vtr, so that you can control the avid from another RS422 equipped device, like a linear edit controller. have you tried that?

I record to my LX1 from FCP a lot, but I always do it manually. I just park the CTI of the FCP timeline on black a frame before the program begins, start the LX1, and as soon as I see the LX1 timecode numbers begin I hit the FCP play. If it’s a one-off or if I just don’t have time, I’ll record directly to DVD and enter chapter marks manually from the LX1 (of course both my machines are in the same room). Otherwise I’ll record to the LX1 harddrive and add chapter markers or make edits or combine different segments there before transferring to the DVDs.

Hi Bob.
Thanks for the tip. I’ll try it. I was also tinkering with actually editing the FCP timeline to tape while sending the second RS-422 output from the Digibeta deck to the DVD recorder and having it trigger into record when the proper timecode location is sent. Haven’t yet had the time to try it however.
As for the Avid, I had tried to use the DVD recorder as the master record deck when doing a Digital Cut. No go either. However, I didn’t realize that it was possible to use the Avid in a VTR emulation mode. This way I could simply “edit” right from the DVD recorder itself I’d guess. Intreresting…
Where would the setting for emulation be found in the Avid application? We are running a pair of Symphonys right now. Version 4.5 possibly. Can’t remember exactly off the top of my head. It would be interesting to try. We usually use the cue up the timeline in black, hit the “reds” on the DVD recorder and then play the timeline when the counter on the DVD decks starts running. It works OK when I can find another body ti push the button for me. The problem is that the deck is in a central machine room and the three edit rooms are all in different locations.
I’ll continue to explore this…when I get some spare time. (yea, right…)

hey tom

glad to help

i dont know where the avid emulate mode is, maybe under device control?

we have a similar one off dvd situation in that we have a lite-on dvd recorder in an adjacent machine room. i have no way to trigger it, so i actually have to bounce the remote control IR signal off the machine room door! (luckily its painted silver). I patch the video out from the lite-on to my 19″ NTSC monitor, and when i see the numbers start, i hit play on my timeline.!
However, i usually do a print to tape to our UVW 1800 betasp, then make my dvd from that. I have yet to get a dropped frame or an unrenderd dissolve from a beta tape! we have 2 lite-ons and i can bang out 2 discs at once when i go from tape (the dvd and beta are in the same room)

Hi again. I tried modifying the device control preset as noted above. While ETT, either editing or mastering, still remains greyed out the PTV routine did work. I set the preroll to one second, the smallest value it would accept, post roll to three and checked the “Auto Record and PTV after:” box.
When I tried PTV it actually DID trigger the DVD recorder into the record mode and all seemed well. However, when I went to title and finalize the disc in the DVDrecorder, all of the options were greyed out as if nothing was actually recorded onto the disc. Hmmm… I tried it again while watching the DVD recorder. Again it played out the time line and triggered the rocorder into Record. At the end of the PTV sequence, the “Stop” button on the deck started flashing as you would expect. However, a few seconds later the “Record” button lit back up WHILE the Stop button was still flashing. Something wasn’t right. Eventually, after hittinbg a few buttons, getting an “encoder error” message and waiting a few more seconds the deck went back to normal. This time, data was recorded on the disc and it accepted titling and finalization as normal. The disc seems OK, but obviously there are some commands going to the deck that are confusing it. I will experiment more as time permits. The biggest thing is the fact that it did, indeed, trigger the deck into the record mode. It’s a good start! At least now I know it can be done.
Thanks again for the tips.
Tom

cool!

i think there is a panasonic protocol, as well as rs232 protocols, in FCP which may be simpler and not too confusing for the poor idda pioneew…:)

goood luck
