  • Cropping Master clips? Newbie question

    Posted by Matt Clayton on July 26, 2009 at 3:57 am

    Here is my situation. I’m using FCP to capture live surgical video. The data stream is via DVI at 1080p60 and using a Geffen DVI -> HDSDI scaler and a Matrox MXO2, I’m capturing 720p59.93 with the Apple ProRes 422 (HQ). The problem is that some of the procedures run quite long and the file sizes get quite large. A video assisted lung procedure this week went almost 4 hours and that’s a 240GB file. A good bit of the captured file, however, is junk and could be quickly trimmed down to less than 30 minutes of usable footage. I’d like to do that and discard the original to save space. Is this the proper use of subclips or is there a way to trim the original? Thanks in advance.

    Matt,

    I’m NOT an expert, so I don’t know the best approach. What I *can* say is that subclips alone won’t help you–they simply point to the master clip which is still intact on the drive, so you’re not saving space.

    The Media Manager (sometimes jokingly referred to as the Media Mangler) should have the capability to delete unused portions of a master clip once you’ve set all the subclips, etc. that you want.

    I hesitate to say anything more, because even though I’ve done something very similar with the Media Manager, I don’t want to steer you wrong–there may be a better way that someone else here can tell you about.

    You need to edit just the required footage into a new sequence, then consolidate the resulting sequence. (just keep the bits of the clip you want by making new clips)
    You do have a backup?
    As you originally recorded directly onto your drives. I hope you also made a tape backup at the same time! If not I’d suggest backing up your media to a backup tape/disk first.

    I would edit the whole original master clip onto the timeline
    (It is easier to zoom into the footage. Long clips in the viewer are often difficult to navigate.)

    Scan the first footage you want to keep then mark an in, use the razor blade tool, or V with the tracks selected.
    Then moved onto the next footage required and then mark an out, or cut again.
    Depending on what you did above you can delete the unwanted clip or delete between in and out X, if you go wrong Z is your friend.
    Continue down your time line saving S from time to time.
    Eventually you will end up with your shorter edited video.
    You can then further tweak the joins and re-edit until happy.

    The resulting sequence will still reference the SAME one original Master clip.

    Please be careful with the following which you undertake at your own risk.
    (You have a back up of your data?)

    To just keep the required media and delete that unwanted, select your sequence in the browser then go into the media manager and COPY the media making sure that “include master clip outside selection” is DE-selected.
    (Handles can be added which give a small amount of media before and after your selected ins in case you want to do a slight tweak in future.)
    The top of the tool says what it is doing. If you do not understand please research further.
    The green bars at the top will also show you want saving in storage you are making.
    Select a destination and new sequence. (Ideally a different drive, then you can remove the original drive and make sure the new sequence and copied media is OK )

    Always COPY your media (you will require even more storage) you CAN NOT get it back if you delete it.
    There is good reason why it is sometimes called the media mangler.
    There are some good video tutorials on the creative cow site on the media manager.

    Good Luck
    Steve
