[Elliot Bendis] “So I’m assuming I need to cut it up into reels. The problem is FCPX with its magnetic timeline ruins all that. And also the audio needs to match the full time code.”
You could duplicate the timeline to as many reels you need to make, and delete the primary timeline in sections using the backspace delete key on a full keyboard, to shift delete on a laptop/smaller keyboard.
Select the clips you want to delete in the primary. Press shift-delete, and those clips will be deleted and NOT ripple.
Also, the length should be fine, since it’s failing on two different apps, my guess is that there’s something funky going on in the timeline. If you are willing to post the XML (or hit me up offline) I can try and take a look for you.
