Exporting a subclip

I too would like to know this. Using my original P2 media on my timeline causes DV corruption when adding any effect or transition. I wanted to make a subclip then transode/export that to another format so I can add my effect to it, but it's a pain to figure it out.

I spent 30mins with someone at the Apple Store in a One to One trying to figure this out, and I have concluded that you can't do it in FCPX (i.e. you can't export just a portion of the timeline or a clip).

You need to open the project in Compressor, set in and out points, and export from there.

Alternatively you could show a clip in the finder, and open in Quicktime Pro 7 and select the portion of the clip you want in there.

This is indeed a real pain!

First, cutting something up with a razor blade is way too time consuming and not proper workflow in any version of FCP. In legacy FCP versions you should have been making Markers in the Viewer, and using them in the Browser as sub-clips. Way faster, easier, more organized.

In FCP X, in the Event Browser, you can select out ranges you want and apply either Keywords, or use "F" to make them Favorites. After creating a Favorite Range in a clip, you can change the name of that range (let view in the Browser), and add independent Notes (right click list header, add Notes, drag it over next to the Names column) to a clip's name, keword ranges, favorite ranges.

As for exporting just that segment, you have to do this, it's not as elegent as Legacy FCP, but it's how it works.

* Select a Clip in the Event Browser, right-click it and select Open In Timeline.

* Now it's in it's own Timeline and you can effect it, just like you did Master Clips in legacy FCP versions, just a lot easier and faster.

* At this point, you have two choices. Trip the clip and Cmd+E to export it, and it will only export the remaining section of the clip. But, be sure to restore it to its full length, or it'll only show up as this length when you drop it in other Timelines.

* Or you can use the Share menu to Send To Compressor, give it In/Out points, and export only that segment there.

As for P2 footage, once it's imported as ProRes, I've never had problems. The only issue could be applying effects and such before that specific clip has physically transcoded to ProRes. When you import like this, FCP X is reading the original data off your media card to allow you access to the footage right away. Only when that clip is fully transcoded will FCP X start pointing to the ProRes version. That's the only thing I can think of with P2 footage. That, and you don't have enough RAM, not a good enough Graphics Card, or are storing your footage on your system drive (a huge no-no).

In the original project timeline, press Cmd-A to select all, then press Opt-G to make a compound clip.

Make a "Temporary" project. Or make it a permanent one to be used whenever you want to export segments of projects. This project is to protect your original project content in case something crashes in the middle of the process when you just deleted 3/4 of your project to export the 1/4 you still had.

From here, there may be other ways to go, but this seems simplest to me.

Go back to your original project timeline, select the compound clip (or select all (cmd-A) if you didn't make a compound clip)

Copy it (cmd-C)

Go to the "Exporter" project and paste it (cmd-V) into the timeline.

Range select the part you want to export first ("Song1")

"Trim to selection" (press Opt-\ (Backslash)).

Export.

Press Undo (Cmd-Z)

Range select the next section, etc.

Depending on how new you are to FCPX, here are a few suggestions on setting the range.

Range select by bringing up the range tool (Press R) and dragging from "Song1" start to end.

Or position the playhead at start, press I (In), then position the playhead at the end, press 0 (Out).

Or put markers (Press M) at each cut point, then navigate to each marker (^, fwd, ^; back), pressing I and O as needed.

And, of course, Option-Backslash to trim to selection before exporting. Then Undo (Cmd-Z) to get it all back and do the next one.
