I have had the same problem with capturing in FCP this week in the middle of my project. I have an imac G5 (before the isight model) and FCP4. Five mins in and it freezes and the whole system crashes. When I start my computer again the clip that was capturing has ‘eaten up’ all my disc space (80GBs!!). I then have to delete this file and start again.
Ive literally just installed an extra 1GB of memory and I thought it had something to do with that as it started happening straight after. Could this be related?
Im in the middle of editing a project and dont really want to re-install FCP. What should I do? How do I re-install QT?
Any help appreciated!
