timecode on 2nd audio channel
Hoping someone can help with a problem. We’re editing using FCP 6.05 on a 2×2.8 GHz Intel box with 8 GB of Ram.
We’ve been asked to provide masters of our shows to be close captioned. We spent a couple of weeks getting bad information as to exactly what the close caption company wanted. Various people told us that we needed to put burned in timecode, and we (thanks to a link from someone here) did just that.
Now they’ve told us that it’s not timecode on a VIDEO channel they need, but timecode on a second audio channel. So basically, I’ll have to pan all the show audio to audio channel 1, and put timecode on channel 2.
Problem being of course, that I have no idea how to do that. I googled, and read some stuff that was way over my head technically. Can anyone walk me through how to do this?
We’re going out to a JVC BR HD50 deck, and via that to a Sony UVW-1800 Beta deck.
Any dumbed down help would be MUCH appreciated!

Decks with this capability will have either a front panel switch or menu item that toggles the audio input on channel 2 between Audio and LTC Timecode. It’s kind of a legacy feature in the digital age, and a lot of decks across formats don’t support it as they have dedicated timecode paths. The last deck that I owned that supported this was a Panasonic 7750 S-VHS recorder. That went into the back room in 2001. I have a UVW-1800 as well and it does not support LTC striping on Audio channel 2.
I don’t understand why the facility is specifying TC on an audio channel. Just so long as it can be output through a TC OUT connector it should work, unless they have some funky old captioning system…

Apparently they (close caption company) get shows sent to them on DVD where the TC is on the second audio channel. That doesn’t make sense to me at all – does anyone know of any way to do that?

Well, LTC is just high-frequency audio chatter(as opposed to VITC, which is recorded in the vertical interval of the video signal, selectable between lines 21 and 22).
If it is recorded on an audio channel as I mentioned in my previous post, then you would switch the playback mode of channel 2 on the deck to Audio and you would hear it and it is also available at the audio output connectors for channel 2. Then you just record that on a DVD (might have to be real-time, I’ve never tried it) I guess there are systems that will re-interpolate that from a DVD. Again , I haven’t done that

I have never heard of anyone asking for this, in fact specs are going down all the time. One company is even fine with web size video. I would look at other CC companies.

Michael,
Your picture looks cool, your tech knowledge and experience does not.
If you are too young to know workflows that have been proven, show a little respect for grey hairs.The answer is obvious.
Take the LTC output of your deck and route it to channel 2 of your destination. (that includes an UVW dubinserting TC out to Ch2 in)It’s just a stupid audio signal making everyones life easier.
If you think you’re wiser than others, make sure you know what you’re talking about.

What? Greyhairs, experience, pictures?
I’m not all that technical. Any help you can give me would be awesome. When I say dumbed down, I’m referring to me needing it to be in simple non-technical language. I’m not talking about anyone else’s knowledge on this board, which would be somewhat silly – given that I’m asking for help no?

I think he was referring to the response by Michael Sacci, not you.
Bouke, wise men don’t flame (except after a nice plate of vindaloo)

Ken is right, on both points.
Sorry about that.Bouke

I guess you don’t care because you’re “older and wiser” but all we’ve been supplying our closed captioner with is mp4’s for about 3 years now. And that’s around 90 originals a year.
But hey some people just aren’t up with technology I guess.

well,
As you might know i write subtitle, CC and transcription software that is quite up to date with modern technology.But i also know that VHS based title software is still in use today.
It’s not about what is possible, it’s delivering conform specs as requested.If that means impractical or more expensive, i most of the time mention that to the client.
99% of the time, the answer is to make it as requested. So i do, and bill accordingly.
It’s not my task to tell other companies what software to use.Bouke
