I’m not sure if i get it, but nevertheless, some random thoughts…
LTC is just an audio signal. With the correct attenuation you can use any transmitter / receiver you may have laying around. (TC is a fairly simple and robust signal that cannot be overmodulated)
Ambient makes transmitters / recievers just for timecode, they are less than 300 bucks a piece.You can feed it to the TC in of your cams / sound recorders if they have it. This works and has nothing to do with Avid.
If you don’t have TC in, you can record it onto an audio channel and use Avids ‘read audio timecode’. This works great from version 5.
(Older versions needed a reelname to be present, and a new reelname for each TC break. This is fixed since version 5.)If that fails for whatever reason, there is always my set of tools:
https://www.videotoolshed.com/product/26/fcp-auxtc-readerIt says it’s for FCP, but it will work for Avid as well.
It can read LTC from QT movies, and from wave / BWF files.
But with Avid, you don’t really need it.
(Could be handy for testing on set though.)The stability of the clock is perhaps not really important as well.
Even if there is a drift, it will be a small one. Since the purpose is probably to sync material, the starting points will not be too far apart (10 minutes max) so the drift will be minimal.
Unless you spend a lot of money on genlocking as well, you cannot expect frame accuracy.
Reason, since there is no genlock, a TC frame can be half over a video frame, and thus it is guessing where it belongs.
But normally this is not a problem, and if it is, it is a very easy correction.The drift on jam synced cameras is horrible. Depending on the stuff, it can be up to a second or more over a shooting day. Don’t do it…
I’ve created a software LTC generator myself (as well as readers of course), and my generator drifts just a few frames over 24 hour without any lock. Probably as good as a hardware one.
But, since your cams also will drift, it is really unimportant.
You can even run Jumpstart on your Ipod / iPhone and use the TC from there. It will just work fine for the reasons mentioned.If you want the next step, get Ambient LockIt boxes, cams that are genlockable, and be prepared to spend a lot of money.
(It is very good stuff, and it’s worth it!)Now, i don’t know what you mean by Group defenitions, and what problems that can give….
Different frame rates will always be a problem, do avoid that at all cost.
BUT, you can mix the tape / disk timecode with audio timecode on an audio track.
Avid assings the audio timecode as AUX timecode, and that is different metadata. If all metadata for AUX matches, there is no problem also. (But i would advise not to mix, as it will create huge confusion….)IOW, if you need timecode hardware, check the ambient products.
If you need timecode software (readers, loggers, generators, custom stuff), contact me.hth,

well, that is where my app. comes in.
It translates the audio tc (LTC) into QT tc.
But, when generating the QT tc track, it needs to know the timebase.
And that went wrong in this case. (inserting 24 fps TC in a 23.976 clip will drift of course…)Bouke

Rafael,
The sound IS the TC in this case.
He’s using LTC on an audio track, and FCPauxTC reader to translate it into QT TC.Bouke

Jason,
Sorry i have not replied earlier.You have stamped your file with the wrong framerate TC.
Kill the TC track and replace it with the correct one.FCPauxTC reader cannot see the difference between 23.976 and 24.
So you have to set it right in the setup menu.
(It will overwrite the current TC track)After that things should work out just fine.
hth,

copy the contents of an empty XDcam drive to the root of a harddrive.
This will make avid think it is an actual drive, and it will export to the CLIP folder.Bouke

use QTchange
https://www.videotoolshed.com/product/42/qtchangeThere is even a video on the site showing you how it works…

Both Mac and Windows versions are updated and should behave better.
Also, there is no serial number needed anymore.So download and toy around!

Santiago,
Download a copy of FCPreconnect from my site:https://www.videotoolshed.com/product/41/fcpreconnect
Read the manual. There is a lot of info in it about how FCP relinks.
Basicly, it does not matter if the duration of the high res file is a bit off, as long as it is longer than the material used.
You will get a warning that there is a mismatch (as there is), but the relink will be fine.However, file names MUST match (this is where my app comes in).
But i wonder, how do you edit with WMV in FCP?
And, how did you manage to get Timecode / Reelname onto WMV?
(FCP reconnect cannot read wmv files….)Bouke
