Mixing OMF and MXF media

[Shane Ross]

Mixing those formats is fine. I do it often.

Gotta be something else.

Thanks Shane.

Are basic set up
Mac OS 10.6.6
QT 10
Avid Media Composer 5.0.3
Media storage are 3 Glyph drives (2 connect by SATA and 1 by FW)

There is a lot of footage that is in French so they had translators come in and use the subcap effect to translate. They say they are having the worst crashing on the material with subcap. But also crashing on non-subcap material.

My first night on the project so just trying to get my head around what has been done.

Well, for starters, 10.6.6 is not supported.

See System requirements here: https://www.avid.com/US/products/Media-Composer-Software/system-requirements

As Shane pointed out, OMF and MXF are just fine. Basic troubleshooting:

Quit Avid, kill all databases on each drive.

Relaunch Avid, let databases rebuild. This may take some time depending ont he amount of files you have. See if problem persists.

Create a new project and import Bins. See if problem persists.

Create a new user and a new project, and import bins. See if Problem persists.

Try copying media locally, and turning off external storage. See if problem persists.

As you can see, we’re systemically eliminating constants; all of which can become corrupted; in hopes of finding the culprit.

10.6.6 worries me the most, however.

I agree with Michael about 10.6.6.

However, if your sequence is loaded with subcaps, that generally slows down any system. Whenever I dealt with lots of subcaps, I rendered them all. That seriously improved responsiveness and working speed.

[Scott Davis]

I think I will do a clean install of the OS and 5.0.3 to start with. Then go through Michael’s list. I saw on the Avid compatibility matrix that 10.6.3, 10.6.4, 10.6.5 are all supported. Is there a preference for stability?

If you suspect that it’s subcap, there’s a chance that there is a corrupt font. I know I was getting a number of segmentation faults and had to pull subcap from a system (a version or two ago.)

If it’s a specific piece of media, you can cut your timeline in half, check it then check the other half. Continue until you find the bad piece of media. Try also to take all your media offline and see if you can scrub through the timeline without crashing.

Best,

I haven’t heard or read any specific comments on those versions. I’m mostly on PC, just occasionally working on my MBP under 10.6.4, wich has been good for me.

[Scott Davis]

Thanks guys. I will try all your suggestions. I had 7-8 crashes last night when I was simply adding descriptors to clips!

Another question. We have an ATI 5770 graphics card. I’ve heard that the nVidia cards are the way to go with MC5. Is that true?

Scott Davis

[Job Ter burg]

That is very true. Read the system requirements in the ReadMe or on Avid’s website.

[Scott Davis]

Thanks Job, I’ve only been on this gig 2 days and trying to suss out why we are having such a rough time.

So far, we are on an unsupported OS (will be installing a fresh, compatible OS and MC tonight) and using an unsupported Graphics card.

The system say “GeForce Family” is there a preferred model for Mac OS 10.6.3 and MC 5.0.3?

Thanks for all the help!
