Closed caption track in QuickTime digitized using FCP 7.0.3

Hi All,

Here are some details about my setup:

Mac Pro 2 x 2.26 GHz Quad-Core Xeon

6 GB RAM

OS 10.6.8

FCP 7.0.3

AJA Io Express (9.1)

I'm digitizing uncompressed 8-bit 4:2:2 QuickTime video from S-VHS and VHS tape sources. When I capture using Final Cut Pro 7.0.3, without fail, a closed caption track (CEA-608) is automatically created in the resulting QuickTime. It seems that the track is empty, and I can't see any captions when I view the QuickTime file in QuickTime Player X and use "Show Closed Captioning". Here is the signal path I'm using during capture:

VHS (Sony SVO-5800) - Y/C out > AJA HD10AVA (a-to-d) - SDI out > AJA Io Express > uncompressed 8-bit 4:2:2 QuickTime video, 24-bit/48.0 kHz stereo audio

I have VANC disabled in the AJA Io Express control panel. When I digitize in the exact same manner using AJA VTR Xchange, a Closed Caption track is not included in the resulting QuickTime. Is there a setting to keep FCP from creating a closed caption track when digitizing from SD-SDI sources?

Any help is greatly appreciated!

I may be wrong on this, but I thought the close captioning was in the vertical interval. Have you tried cropping the image in fcp to eliminate the close captioning.

I think closed caption data for SD content is visible on line 21, and it can be seen in a broadcast monitor using underscan. I can re-export the video, or even delete the track in QuickTime pro and re-save the QuickTime. That will get rid of the empty track. However, I'm digitizing content for archival purposes, and I'd prefer not to add another step (and one that I might forget to perform) to an already cumbersome workflow.

I think it's strange that FCP would automatically create an EIA-608 cc track. I wonder if anyone else has experienced this, or knows how I can keep it from happening?
