NLE Mac / Final Cut questions from 2004

Jeff Donald · November 23rd, 2004, 06:37 AM

That's very odd Jerry. I used to use AE a lot and don't ever remember a lot of jumping. How slow are you trying to get? Maybe the clips need to be longer than 4 seconds to get the smoothness you want. what type of color effects? If you go into extremes it will cause banding and noise.

How in God's name do I open the MPEG 2 window pane?
I'm about to shoot something.
1.2.1

Gary Chavez · November 23rd, 2004, 10:44 AM

nevermind, got it.
And I didnt shoot anything.

If I have a project of any major nature ($$$) I try to designate one specific external Firewire drive for this job (after ascertaining that this drive has enough room) and capture everything to it, plus do all my rendering and save all versions of the sequence, and other media used in the job like audio and Photoshop files there.

Then I don't have to worry, I can plug it into literally any computer that has FCP installed, carry the job between locations easily, return a rented computer on-location and finish up at the home office etc. or just not worry if something goes wrong with the computer.

Cameron O'Rourke · November 24th, 2004, 11:11 PM

Help. I'm working on an 8-minute industrial that captured into FCP just fine, but now am hearing a 16-frame audio drift when working on the timeline and when I go to export to either QuickTime or Compressor.

The video was captured 8-bit uncompressed 4:1:1 from a DigiBeta deck to an XRaid. Editing was done on a G5 connected to the XRaid and all was well.

The entire Capture Scratch folder, supplemental media and the project file were copied to a LaCie Big Disk Extreme 500Gb drive over Firewire 800, a total of 350Gb of material.

I brought the drive home and attached it to my Dual 1.42Gh G4. I have another LaCie 500Gb that I use for my Final Cut Pro render/cache files attached in a daisy chain over Firewire 800 to the previously mentioned firewire disk.

The project is nested. The main edit is in its own sequence. That sequence is nested into "master" sequences that include color bars, a slate, and a broadcast safe filter. The master sequences also include a monolithic mastered stereo audio track that was done outside.

The sequence containing the main edit, with all of the original audio plays back fine. However, on the master sequence, the mastered audio track drifts to a lag of about 15 frames at the end of the 8 minute spot.

Attempts to scale the audio just seem to cause unpredictable results when I export -- sometimes the audio leads, sometimes it lags.

I'm absolutely pulling my hair out. I don't think this is a disk throughput or CPU issue as the lead/lag is encoded that way in the QuickTime -- I believe this is true as when I start/stop or scrub through the QuickTimes the lead/lag is always the same.

I've read everything on "audio drift" and "audio sync" I could find -- can anyone shed light on what might be happening?

Thanks,
Cameron

Jeff Donald · November 24th, 2004, 11:32 PM

Nesting can cause problems with the audio. Have you any "old" un-nested versions you can try? I try to save several copies when I start to nest sequences. Copying files can also lead to sync issues. Did you use the Media Manager to move the files?

Cameron O'Rourke · November 25th, 2004, 12:30 AM

Well, the nested edit sequence is pretty messy so I'm not sure I want to layback the audio track onto that. However, while playing around with the sequences, I created a new sequence, nested the edit sequence in, and then layed in the audio track. And, surprise, the audio sync'd up perfectly (I checked it against the orginal audio.)

So, although serendipity is a great thing, and I'm back in business, I'd sure like to know what is going on.

Thanks,
Cameron

Jeff Donald · November 25th, 2004, 06:47 AM

I don't have a good answer, other than nesting occasionally cause audio sync issues. I'm sure apple is aware of this and it will be addressed in future versions.

Steven H. Denn · November 25th, 2004, 08:36 AM

I can't open my Audio/Video Settings.

I get this mssage (General Error 34)

I thought if I made a new project it would go away, still there.

I have read, trash the prefs, delete bad audio, delete a empty layer on a photoshop graphic.

My son had started a slide show using bmp's & a Aiff music track

Any clues?

Thanks

Rob Lohman · November 25th, 2004, 08:44 AM

Which program are you using?

Steven H. Denn · November 25th, 2004, 08:50 AM

FCP 4.5

Cameron O'Rourke · November 25th, 2004, 10:13 AM

Thanks for the lead about the nested sequences. That's what led me in the right direction.

Happy Thanksgiving,
Cameron

Rob Lohman · November 25th, 2004, 01:21 PM

I've moved your thread to our Mac editing forum. Hopefully there
are some people here who can help you out. Good luck!

Not sure if it would help, but have you tried mixing down the audio before nesting your sequence to the master?

I'm shooting on the xl2 in 24p mode and I'm wondering do I need to change the settings on my FCP system? Before this I was shooting with an xl1-s. running FCP 4.5. Thanks
