Hi Guys!

GSW, I don’t really know what is causing your audio out of sync issues, but just as a hunch I’d check the sample rates of your cameras, most DV cameras have two sample rates for recording audio: 48KHz in “SP” mode (this is the highest quality setting and records two channels of audio to the tape) and 32KHz in “LP” mode (this is the low quality setting, the tape lasts longer and 4 channels of audio are recorded, it’s useful if you’re doing audio overdubs or narration in-camera).
This could cause the sync issues you’re seeing but it’s a remote possibilty: when digitizing through FireWire, Producer detects the sample rate automatically and changes the Hardware Input Setting acordingly.

As for your second problem the “do you really want to master this non-drop frame program with a deck set to drop-frame”…

This is typical of Time Code issues in NTSC world and our European friends are free from it… as you may know, due to not being running exactly at 30fps, NTSC Time Code accumulates over the lenght of a program a difference or discrepancy with the “Real World Time”; this causes problems for Broadcasters that have to measure and plan their programing schedule accordingly to this “Real World Time”…

So, to have Time Code and lenght match the “Real World Time” clock Drop-Frame Time Code was introduced, as its name says it “drops” frames to match “Real World Time”, only IT DOES NOT DROP FRAMES (confusing, uh?) what it drops is the Time Code Frame Number every once in a while to compensate for the discrepancies with the “Real World Time” clock.

So, your system is not droping frames, it’s just asking what kind of Time Code flavor do you want written to tape.

As you have stated, you do have your Program Default set to Drop-Frame, but I suggest you do a double-check and confirm that the timeline of the program you’re trying to get to tape is really set to Drop-Frame….with the timeline active go to Progam and search for a command that says “Show in Drop-Frame”if your program is in Non Drop-Frame and viceversa… other way to check is to look in the Time Code window in the timeline: if the character between each pair of time code numbers is a “:” then your program is in Non Drop-Frame, if it is a “;” then your program is in Drop-Frame mode.

Well once you’re certain that your program is in Drop-Frame mode (if that is what you wish… usually if your program is for broadcasting it HAS to be in Drop-Frame, and most DV decks -don’t know about the JVC- are set by default to Drop-Frame Mode, if you’re going to postproduce or do DVD authoring it’s better to use Non Drop-Frame mode), you can output to tape, if it gives you the error again, get out of master to tape mode and turn your DV deck off, wait 10 secs and then on. That’s it.

Sorry for the long and convoluted post, but I’m writing this as it comes to my head (and english is not my first language)… hope it

Thanks Floh!

So, you would say that, for HD, making the investment in FibreChannel is worth it?

Floh and SoftHarbor:

Thanks for your quick and insightful answers!

Hi again!

I also got this one from the Avid Community Forums, note that this is not an official Apple Website… And I beleive you would be safer doing a System Archive and Install…

Hi!

The procedure goes like this:

First download the reinstaller for QT 6.5.2 from here:

https://www.apple.com/support/downloads/quicktime652reinstallerforquicktime701.html

Warning!:

The QuickTime 6.5.2 reinstaller will remove QuickTime 7.0.1 from a Mac OS X 10.3.9 system and restore QuickTime 6.5.2.

This reinstaller will only run on Mac OS X 10.3.9.

As far as I know Tiger (10.4.x) won’t work with QuickTime versions previous to 7.

You don’t tell which version of MacOS X are you running…

Then using the QuickTime preferences panel upgrade QT 6.5.2 to 7.0.1.

Hope this helps…

P.S. If this doesn’t work or if you’re using Tiger instead of Panther you’ll have to do an archive and reinstall of the complete OS X.

Regards.

Well, at last we solved it.

It seems that the pulldown parameter in ProTools was on.

Also I decided to stop working with DVDs and returned to use QuickTime movies for the sweetening sessions, the settings that work better for me are as follows:

Motion JPEG-B, 360 x 240, 29.97fps, single field, non-drop frame, data rate limited to 635 KB/sec, audio track is 16 bits @ 48KHz, uncompressed.

These give me small file size (1 GByte for a 28 minutes program) and good enough quality for doing lip syc in ProTools.

I export the audio tracks from my NLE one by one (I don

Also I included one sync pop at the head of the program and another sync pop at the tail.

Hi Ty!

Thanks for your fast response.

The audio comes from a finished Master in Betacam SP that I’m re-editing.

It was digitized into my system at 16 bit @ 48KHz, 29.97 fps non-drop frame… I guess that since it is being redigitized from analog, the original sample rate and speed is non-relevant now? (Not sure).

The people at DUC tell me its a pull-down issue, but the ProTools guy swears that his settings are correct…

I’ll try RAMPS and I’ll keep you posted.

Hi!

You don’t say what version of Media100 are you working on… but if you have access to a MacOS X machine you should try ffmpegX, I use it every day and its great! Also it’s free.

You can get it here:

Hi there!

Yes you need QT Pro for using Flip4Mac.

If you had QT Pro the procedure to export a WMV movie goes:

1. open your by reference file with QT Pro

2. From the FILE menu choose EXPORT

3. In the dialog window that appears you choose Movie to Windows Media

4. Depending on the version of Flip4Mac yoa can choose different SETTINGS, such as frame size, frame rate, data rate, one pass, etc.

5. You write a file name and press SAVE

That’s it!

Let me tell you it’s a great product, every day I use it for sending clips to clients anf it makes my life really easy. I believe the price is reasonable, including the fee for QT Pro.

Good Luck!
