i agree 100%. go with Premiere if you want easy. But then again, I wouldn’t want to print to a digibeta deck with Premiere.

If I make an image file in photoshop that is 720×486 and drop it into a 720×480 FCP timeline and resize it to 98.8% it looks exactly the same. Why? And why wouldn’t DVCPRO50 be a full 720 wide? Whatever its got going on just looks bad 🙁

Capturing with a Panasonic AJ-SD93 deck via Firewire and FCP 5.1.4

Blast. Fixed my own initial problem. Have to do an “audio mixdown render” to get audio to go through. Anybody know why?

Is edit to tape working for you?
So to fix this problem-
1. Go to sequence settings in FCP, then the “audio outputs” tab. Make sure its set to 4.2. Go to your timeline where you have 4 tracks of audio. Right click next to the lock and make sure audio outputs are set 1 to 1, 2 to 2, 3 to 3, 4 to 4 (this is most likely your problem).
3. Go to Audio/Video Settings under file. Go to “device controll presets”. Click “edit”. Make sure audio mapping is set to 4 channels.

Have you set the internal timecode preset on the VTR? Every time you record on the VTR it advanced the internal TC, if you rewind and record again it will start where you left off. You need to reset this to match your inpoint. Email me if you have anymore questions: dave@desmoinesfreelancer.com

haha. Ya know what. I don’t even care anymore. We are getting “exception” status and delivering NTSC instead of PAL and you cant even use line 21 in NTSC. Guess this means I don’t have to meet their timecode specs. 🙂

Got it fixed!
Just for future reference for anyone with the same problem (doubt it will EVER happen to anyone else), here i the solution, at least in my case.
We have a Sony DVW-2000 DigiBeta deck. In the extended menu (which is turned on or off by a switch that is on a chip board that you have to pull out of the deck) there was a setting, Item Number 713 (video setup reference level), that was not set to default. The master level setting was set to 0IRE instead of 7.5, to understand what exactly that means, take a look at your manual, it explains it, …sorta. Basically it has to do with adding and subtracting it from inputs and outputs and stuff.
And to sing the praises of having a waveform monitor… I wouldn’t have figured out that it WAS fixed, after I fixed it, without it. Get a scope.
If anyone does have this problem in the future, feel free to email me dave -at- savedeth.com

the heavens opened and here and behold, i have a waveform monitor (on lend from tv station).
Everything I am reading through it, as far as black levels goes, is 7.5 IRE. That is from my AJA, and from the digibeta deck. If I unterminate the digibeta deck, i get 15IRE with whites out of view. That is obviously not the problem because I went to there studio and saw my tape in their monitor, whites where in the correct spot, only thing was, 15IRE black level.
I also ran bars from our standard def, digital camera. (Panasonic SDX-900) If I had the “7.5%” setting on, blacks read at 7.5 IRE on the waveform monitor (which is analog), if I turned the “7.5%” setting off, IRE on the waveform monitor showed 0IRE. This would “disprove” that you (bob zelin) said. But I believe you, I just need an explanation for what I’m seeing.
Soo….. everything looks good on my end. Looks to be their problem. But this is a super legit station, I don’t think they’d be cutting engineering corners. Also, I saw them put in another tv show and their bars where correct. But I heard them mention that this other tv show was also having problems. Maybe they just turned there black levels down to 0IRE?

Amen brother! …fact is, I don’t pay bills, no scope for me 🙁
I am just trying to understand everything so I have a better understanding of what the problem could be.
For the reference we have an SDX-900 not an HDX-900. We are shooting standard def not high def.
So if the camera is set to “7.5%” does that do a fake digital black level adjustment that results in about 7.5 IRE? So the DIGITAL setup level would or wouldnt be 0? I know normally digital black level is set to 0. But the camera “IRE” level is set to 7.5. So it is my understanding it is NOT 0 digital black level. Am I right?
“If you take the analog output and go into a product (like an AJA), it doesn’t “add” another 7.5 IRE to the setup – it keeps it the same.”
-understood.
“Remember, there are analog waveform monitors, and digital waveform monitors – analog looks at anlaog signals, and the setup level is 7.5 IRE as specified by RS170A standards. Serial Digital scopes will display an SDI (not an HD-SDI) signal, and the SAME signal will drop the setup level to 0 IRE (or digital 16)”
-does this mean a 0 digital black level video when exported through something analog (like an AJA) will have 7.5 IRE? How so? Because 0 Digital black is different from 7.5 analog IRE?
