Adding a filter deletes closed caption in my movie

I have a client who has a 30 min. tv program. We re-run some issues. They all have to be close captioned. When I capture a past CC program and add any time of a filter, the close caption is lost. Is there a way to add a filter, say proc amp, and not lose the close caption?

All Line 21 data is lost whenever media is rendered.
See the FCP online help for LINE 21 for additional information.
As Chris notes, encoding closed captions must be the last thing done in a digital workflow and it's almost always done on on inline system while going out to an analog recording media like tape.

This is my standard sigfile so do not take it personally: "For crying out loud, read the freakin' manual."

Thanks. These programs are re-runs and the client is trying to save the charge to close caption the same program again. All I was trying to do was adjust the video level with a proc amp filter.

Bare with me here,, might have a creative work around for ya.
How are you capturing??? Is the line 21 info retained if you capture and output without adding any filters??
If so, and you are using a Kona Card (LHe anyways.) Capture the video analogue through your Kona card, using the AJA Control Panel proc amp to adjust your video levels as you capture. In the 'Log and Capture' window open up the 'Clip Settings' tab and click on the 'video scope' button to monitor your adjustments if you don't have proper scopes.
Then, lay it all back to tape sans-filters!
This is of course of you are using an AJA LHe card. Don't know if this would be possible with a Kona3. Don't use BM so not sure if possible with those cards either.
I only just thought of this so I'd do a test clip first just in case this doesn't work at all!!
