I am wondering if taking a hour to export a 2:30 long project to a 1080P h.264 file is normal? I am using the original media, h.264 files from a Nikon D7000 and they play fine on my machine.  I have several effects on half the files, including Neat Video noise reduction.  Should I use background rendering or not? (I am using it now) Also I am using the X264 codec.  Is that slowing me down? I am thinking about how long it will take to export a 15-20 minute project. All day?

 

I am using a MBP, 2.5 GHZ, 8 GB RAM, my events and projects are on a separate firewire 800 7200 rpm external drive, OS 10.7.4, FCPX 10.0.5.

 

Thanks

    It is excessively long for normal formats but I don't know about the weird non-standard codecs Nikon may be using.

     

    That video  should take less than 10 minutes unless there is something we don't know about.

    I am not sure what other information you may need.  I have sent the project to Compressor and it has been running for 25 minutes and it is only half way finished exporting. This is the kind of thing that might send me back to Premiere Pro CS6.

    I tried the "export media" setting, choosing h.254 and it only took 10 minutes or so.  If I choose "export using compressor settings", or "send to Compressor" and use the 1080P selection for Vimeo, it runs for an hour or more to export 2:30 of project. Is this a single pass vs multi-pass thing? Does Compressor take longer becaiuse it outputs a superior result?

     

    Thanks

    Could be.

     

    What Compressor settings are you using?

     

    Multi-pass, VBR and Max Quality as opposed to High Quality can easily quadruple or more the encoding times.

     

    They do result in better quality but as with all claims of a video nature, the difference is often hard to see and rarely justifies the excessively longer compression times.

    I have the Compressor setting at single pass, high quality and it tells me in the share monitor that it will take over an hour to export the 2:30 video, but when I select h.264 under  "export media" in FCPX, it took less than 5 minutes to export the file.

    This is for FCP7, but in my experience, applies also to X.

     

    Good luck.

    I exported the project as the tutorial suggested, but when I dropped the file on Compressor, it wasn't much quicker. However, I found that mpeg stream clip would convert the Prores422 file to h.264 as multi-pass, 100% quality in about 8 minutes.  An extra step, but it saves me an hour or more.

    I think your problem may be the Compressor Presets for YouTube etc.

     

    They have ridiculously high data rates of 20.5mbps  plus all the bells and whistles of   multi-pass and frame reordering.

     

    None of these things is necessary and they all combine to create huge files and excessive encoding times.

     

    You need to create your own more efficient custom preset.

     

    If you don't know how, email me and I will send you one.

    Thanks for the advice.  I built presets for 1080P and 720P using Vimeo's posted settings, and the exporting is much faster.  I am still exporting as Prores and then running it through Compressor.  So the question is, really, what settings provide for higher quality, without taking forever to export?

    Can you save the presets as droplets and post them somewhere? I'd be curious to see what settings you're using. Thanks.

    I don't know if your using qmaster quick clusters, but that speeds up the rendering in compressor.

  • 12. Re: export times

    I tried to set up the clusters, but must have left a step out because after I click on submit in Compressor, I don't see anything except The Computer under clusters.

    Tom,

     

    I'll see where I can park them. I used to use mobileme for that, but that seems to be no longer an option.

    If you have nowhere to put them you can email them to me and I will pass them on to Tom. (Click my name for my address).
