What are the limiting factors of Final Cut Pro X? Where do I find a statement of time limit, gigs, etc?

I can't find this for iMovie '11 either. Where is it?

Mac Pro, Mac OS X (10.6.8)

    I thought this recently came up in another thread, but I couldn't find it.


    Presumably there is a theoretical limit, but AFAIK, there's nothing published by Apple.


    As a practical matter, it's a different story. Depending on the complexity of the project and how robust the hardware is, as project length increases at some point  FCP's responsiveness will decrease. At point there are a number of strategies that can be used to complete the job.


    Are you just curious or were you contemplating something specific?

    Russ is right. It is a factor of hardware, not software. RAM, CPU speed, GPU speed and amount of media storage. Most of us break up long form projects into 20 minute segments.

    I have not seen anything published, but architecturally, FCPX will make a much longer movie than iMovie.


    iMovie will do all rendering in one pass, when you share the project.


    FCPX can and does do multiple renders, so while it can do much more complex editing and effects, the load on your processor, graphics card, and memory can be much lighter than in iMovie, so you can do much longer projects.


    In iMovie, you have to juggle all the balls in the air at the same time. In FCPX, you can jusggle a few balls at a time until you are done (and this is all handled by FCPX - it is nothing you have to worry about.) 


    The only decision you have to make is whether to allow background rendering, so rendering starts whenever your processor is idle for a few seconds, or to wait and do your renders at the end.

    These are three helpful answers. I'm trying to think ahead in planning my next project. If I break the project into 20 minute segments as suggested, a good idea, I'm not sure I know how to burn several segments in sequence on a DVD? I don't seem to find that info in Pogue's Book iMovie '09 & iDVD. I have not bought the iMovie '11 book. So the question becomes, how can I burn 3 or 4 20 minute segments in sequence, or is it best to burn them onto separate DVD discs?

  • dastoelk Level 3 (665 points)

    No problem. You actually join ALL those segments together into one project just before you export.


    This is just to keep things from slowing down DURING the editing process. Once you are finished, it's quite okay to make one big timeline / projext.


    BTW: You can add chapter markers before bruing to DVD.

    Depends on your authoring tool.In DVD Studio Pro, Encore, iDVD, Toast et al, you can do multiple tracks and have links to those tracks. Make each a separate chapter.  If you make your DVD in Compressor or FCPX, you'll need to cut and paste to a master sequence because those programs are one-track authoring tools. If you want them to be individual chapters, inset a gap clip between them, and then put in chapter markers.


    Your project isn't unusually long. You may be able to do it in a single project.


    Good luck,

    One more thing…apropos your original question, here is an interesting and informed thread.

    Proper workflow is that you never make hours long timelines to edit in.  Not even Hollywood editors do this.  You break your production up into Scenes.  Do one Compound Clip per Scene.  When done, drop all of the Scenes into a Project timeline for assymbly and export.
