Audio Pan setting is -1 on imported clips
-
[Jeremy Garchow] “It’s not that much work. Open l&c, choose settings, close l&c, choose clips to batch capture, uncheck box. Pretty easy, especially if it fixes the problem. “
Well… Isn’t that something. It does work after doing this. Strange behavior.
[Jeremy Garchow] “You started capturing with a different HDV system, then you have to tell FCP to use the log and capture method, of which is guided by AJA. Think of it as changing preferences.”
I know what you mean totally, but shouldn’t dual mono be dual mono in any method you choose? Basically, you cannot capture dual mono from firewire no matter what. You’ll get 2 channels of unlinked stereo audio. That looks to me to be a bug in the software, not a quirk.

A little strange, yes, but it works and is a fast fix.

Perhaps. I don’t have an HDV source to test it. I assume you’ve sent feedback to Apple?

[Jeremy Garchow] “A little strange, yes, but it works and is a fast fix.”
Well, sort of…. Its still a non-linked stereo signal. It shows up a 2 channel mono but place it on a timeline, and you’ll see that its still panned left and right. Oh well…
[Jeremy Garchow] “I assume you’ve sent feedback to Apple?”
Many more times than you can imagine.

Not here. It comes in as dual mono. Panned center. Must be HDV juju. Are oyu sure you have all the settings correct? You shouldn’t have to use the browser to change settings at all, just the log and capture interface.

“I think it has to be that HDV juju. Yes, all of the settings are correct. And we use the Browser to change the audio from 1 stereo to 2 mono, at the same time, it blows the metadata for the ProRes422 at 1440×1080 in their respective columns in the Browser. There’s an issue with recapturing into anything if you don’t do this step.
Now, the one thing I have not tried is to leave all the settings alone, just delete the media and change my audio defaults in the Log and Capture window, then use those settings for recapture. Maybe it can recapture ProRes422 in its native aspect, too. Hmmmm… it’s worth a try.

That’s exactly what I would do. In log and capture choose, codec/frame size and audio. Then Close log and capture, then right click clips to batch capture and UNcheck the ‘use logged clip settings’.

Dude…. I just found a HUGE bug here. I did just as we have talked about.
BUT… the audio still plays separate channels, not centered between two channels like it does for our XDCAM HD footage, or anything else captured thru the Log and Capture window. I can look at the output on the audio meters and it shows channel 1 on my timeline being output as channel 1 ONLY thru the Kona card, BUT… the analog monitor of the Kona 3 card is playing thru both channels 1 and 2. I cannot change this for anything. The audio sounds just like stereo audio, not mono audio.
Now, if I import some XDCAM HD footage using the Sony software, I’ll get two distinct audio channels that play separately thru the Kona’s analog monitoring to my audio monitoring board (of which I checked to see if I have that setup properly, too).

Not sure if I am following you here. Can you re-explain?

Wait a minute… Sorry. Someone has been messing with my audio board. Don’t worry about the Kona monitoring thing.
BUT, my dual channel audio is still panned left and right, but ONLY when recapturing from an HDV source into ANY codec using ANY method. I wonder if that is because HDV 48k records 1 stereo track, even if they are two distinct tracks of audio from two different lav mics.
Even if this is true, I’m recapturing thru the Kona 3 card and if I tell it that my audio is dual channel mono, I should get two tracks of center panned audio, right? This is the case if I capture footage from any other source like BetaSP or XDCAM HD, but not from an HDV source.
No matter what we have talked about, I still get two tracks of left and right panned audio, no matter what the settings are. Its just not linked like stereo audio but still acts like it.

Hi Jeremy,
Thanks for helping me with this issue.
[Jeremy Garchow] “Look at the audio mixer (option-6). If it’s a stereo clip, I am sure ch1 is -1 and ch2 is +1, i.e. a stereo clip.”
You are correct, ch1 = -1 and ch2 = +1[Jeremy Garchow] “When capturing you can usually choose to bring them in stereo pair or dual mono.”
When capturing I use Final Cut’s “Log and Transfer” utility. How can I choose to bring the clips in as dual mono? The options on the L&T utility come in the form of 2 buttons, “Logging” and “Import Settings”. I don’t see any dual mono settings in either one. “Logging” consists of Reel, Clip Name, Scene, Shot/Take, Angle, & Log Note. “Import Settings” consists of a “Video” checkbox and “Audio (Audio is mixed down to stereo)” checkbox.The only place I found “dual mono” is under Final Cut Pro – User Preferences – Audio Options tab, I found “Stereo Monitoring L+R” preset checked. I duplicated it as a new custom preset, and edited my new custom preset as “Grouping = Dual Mono” instead of “Grouping = Stereo”. I left everything else as the default, which is Outputs=2, downmix (db) = -3 for 1 and 2 (I think that is referring to each channel). The new custom preset is now checked.
After configuring the new custom preset, I still run into the same problem after I import clips, so I’m missing something. This issue also happens when I bring in any other audio, like music or voice over audio clips. So it’s not just happening to clips that go through “Log and Transfer”
After searching the internet and playing with Final Cut for awhile, I’m not sure how to unpair an exsisting audio clip and make it dual mono. However, if I can configure Final Cut to bring all my clips in as dual mono, I guess I don’t need to worry about how to unpair and make a clip dual mono. I can stick to dragging the Pan = 0 until I figure this out.
