  • XDCAM HD Question

    Posted by Glyn Bowerman on April 13, 2010 at 5:47 pm

    Hello
    I’m using a Macbook 2×2.26 Quad Core, running Final Cut 7.

    Up until now I have only really captured tape based formats via Firewire.

    We now have a project where we are having to edit using from XDCAM HD 23GB Discs and the files are .MXF
    We have hired a SONY PDW-U1 and this mounts on the desktop fine.
    I have downloaded the XDCAM transfer software & when I ‘right click’ import in FCP, i can ingest these files just fine.
    When they come in, although they were filmed @ highest quality 50mbps, FCP converts them to around 7.1mbps…why is this and is this normal?

    I have tried to use the Log & Transfer aspect of FCP as well, without much luck. Should this work? and would this be a way to convert them to ProRes? or would they stay native XDCAM.
    I know you can use MPEG Streamclip & Compressor to convert to ProRes but this seems long winded & I doubt the software would like these files anyway.

    I’m on a really steep learning curve here chaps & its a bit daunting not knowing the best way to approach it. Any advice would be greatly appreciated.

    PS. I have an AJA Io HD as well, so have read that ProRes is the way to go..but its a minefield of conflicting information!

    Sorry in advance if my answer is stupid, but I recently ingested XDCAM footage for the first time myself and once I downloaded the software I had no problems (up until colouring but that’s another story!).

    When you say you right clicked, do you mean you right clicked the actual files and imported them? I found that once I downloaded the plugin a new import option popped up in my FCP file menu and it just seemed to do everything automatically and the res was fine with lots of really big files.

    Have a search under my name and XDCAM/EX footage and you’ll see the answers given to me by the more experienced members of COW.

    Hope this helps.

    [Glyn Bowerman] “When they come in, although they were filmed @ highest quality 50mbps, FCP converts them to around 7.1mbps…why is this and is this normal? “

    What you are seeing is two different numbers… XDCAM HD 422 records at 50 mbits/second, it imports into FCP as 7.1 mbytes/second. There’s a difference in bits and bytes. There’s a bunch of math here and I’m sure you really don’t want to know the full explanation… but the numbers you are seeing are correct.

    Let me ask you this, what is your primary format for your edit? Is it mostly or all XDCAM HD? If so, use the Sony Software Transfer to import all of your media and set FCP to render your XDCAM HD renders to ProRes 422. You can do this in your User Prefs. I would suggest that you edit in XDCAM HD, unless you have lots of graphics. In that case, I would batch capture my footage into ProRes 422 or even DVCProHD.

    Let me give you a little tip here. If you need to edit in ProRes 422 or some other codec, for whatever reason, import your XDCAM HD footage, log it, then take the media offline and batch capture into another codec. This will save time, instead of looking at all the media like we do on tape.

    Thanks Wayne

    Yes the project is being filmed entirely in XDCAM HD. So when I drag a file onto the timeline & FCP asks would i like to match the clip settings, I click Yes, then go to User Preferences/Render Control, then change the codec to Apple ProRes 422 ?

    Thanks for the other tip, I have never batch captured before so will look into it.
