Equally/Setting Audio Levels in FCP to match Analog Beta Decks

[Jerry Hofmann]

I see this too… it’s been there a long time as well. Never got a good answer as to why, but this is how I handle it:

I set the record levels on the Betacam during playback of the audio… then I leave them alone. I go back to the sequence, and play the bars and tone, adjusting the tone until it hits 0 on the beta… This requires that the bars and tone are in the sequence… but what I do is certainly working.

Thanks Jerry for the quick advice!! I will try the QT pro trick and let you know.

Thanks

When I open up bars and tone I set my tone level to -20 dB in FCP (I actually adjust the volume on the tone media to -20dB from -12dB) Then with my -20 dB tone playing from FCP, I set my Betacam “0” level. (I also set up my D9 deck to -20 dB). Then when I do a final mix in FCP HD I mix to -12 dB with the little audio meters and make sure I don’t have anything peak over -10dB.

That seems to work really well for my set up. Once I had tone set, I used to watch my levels on the deck rather than FCP, but it always seems to come out right this way.

Now if there was only a way to keep my tone media set at -20 instead of having to adjust it every time……

Thanks Matt! I will give that a try.

The way I accomplish this to create a project called (are you ready?) “New Project”.

I set up all the windows, presets, and bin headings the way I prefer.
I have a “clean” Timeline with :30 of Bars & Tone, a generic slate (even a version with an animated countdown).
I save the project in this “ready” condition and LOCK the file in the Mac’s “Get Info” window.
This keeps this “master copy” from being accidentally modified.

Then, when I want to begin a new project I go to my FCP Documents Folder and double-click this “New Project” and, after FCP opens, I immediately “Save As” the REAL name of my project.
When you do this, you’ll automatically have both your original “New Project” locked file and the Newly-named unlocked (ready to edit) version.

The key to this process is the Mackie mixer and for arguments purposes when I say mixer I mean a Mackie 1402-VLZ Pro.

This in “Old Fart Broadcast Engineer” parlance is called “Unity”. And now let us discover the Zen of this lost art.

1. With a tone generator produce a tone at 1 Khz and 0dBu through the Mackie mixer from an external source or from a FCP tone and bar sequence. Pot-up (oops old school term) the source–NOT THE MASTER OUTPUT!–so the master output from the Mackie is 0dBu.

As a sidebar the two sliders on the Main Mix should be set to “U”–oops, what’s that? Unity.

2. Now record the 1 Khz tone and bars to tape on the Beta.

3. Now playback the recorded bars and tone. Set the playback output on the Beta deck with the two pots available on the VTR, if it is a BVW or PVW, for 0dBu on the Beta slider assigned on the Mackie either LINE IN 7-8, LINE IN 9-10, LINE IN 11-12 or LINE IN 13-14. If not it may a menu item for UVW Beta’s–I can’t remember. You have now calibrated your Beta source deck to the Mackie.

4. Now your video/audio board will affect the this–adjust a bars/tone coming out of your FCP for “U-Unity” ie. 0dBu in the Mackie. If you board doesn’t have this ability you may well have to adjust your individual clip settings. For layoff to tape I use to have to set the tones for -16 because my old AJA Kona SD (1st generation board) with a Promax DA-MAX+ would never retain its DA adjustments (Distribution Amplifier).

5. When I then mastered to tape, I would nest my finished projects sequence inside my Tone/Bars/Countdown sequence. I would mix my main sequence project using FCP’s audio meters. If I needed to do an overall project tweak for master, it would be in my Tone/Bars/Countdown Master sequence–usually it meant adjusting the nest Main Project Sequence -4 DB to -16 DB from the standard -12 DB like my Tone/Bar/Countdown.

In the old school of engineering the output of your FCP video/audio board, the audio would go through a DA (Distribution Amplifier) and adjusted for “U-Unity” on your Mackie mixer which would be -12 DB in FCP if I remember correctly.

I am doing this from memory–the equipment is not around me–so your mileage may vary.

If you are using FCP with the Aja IO setup, here is what their manual says:
