I recently recorded some HDV footage (.M2T mpeg) for someone else to edit in iMovie. I added a soundtrack in Adobe Premiere on a PC and need to export it out. Should I convert it to something else?

    When iMovie imports HDV from tape, it converts it to Apple Intermediate Codec.

    I am not sure if your .M2T will import or not. I suggest you test it, or convert to AIC.

     

    Also, there is a free app called MPEG Streamclip that can convert m2t to Apple Intermediate Codec on the Mac.

    Apple Intermediate Codec is not likely to be available on the Windows version of MPEG Streamclip, so I would suggest converting it to h.264 codec within an MPEG4 container at a high bitrate.

    the file icons have padlocks on the Mac

    You can change the permissions in Get Info.

     

    You need to convert the VOB files in the TS-Folder of the DVD back to DV which iMovie is designed to handle. For that you need mpegStreamclip:

     

    http://www.squared5.com/svideo/mpeg-streamclip-mac.html

     

    which is free, but you must also have the  Apple mpeg2 plugin :

    http://store.apple.com/us/product/D2187Z/A/quicktime-mpeg-2-playback-component-f or-mac-os-x

    (unless you are running Lion in which case see below))

    which is a mere $20.

    Another possibility is to use DVDxDV:

    http://www.dvdxdv.com/NewFolderLookSite/Products/DVDxDV.overview.htm

    which costs $25.

    For the benefit of others who may read this thread:

    Obviously the foregoing only applies to DVDs you have made yourself, or other home-made DVDs that have been given to you. It will NOT work on copy-protected commercial DVDs, which in any case would be illegal.

     

    And from the TOU of these forums:

     

    Keep within the Law

    1. No material may be submitted that is intended to promote or commit an illegal act.
    2. Do not submit software or descriptions of processes that break or otherwise ‘work around’ digital rights management software or hardware. This includes conversations about ‘ripping’ DVDs or working around FairPlay software used on the iTunes Store.

     

    If you are running Lion:

     

    From the MPEG Streamclip homepage

     

    The installer of the MPEG-2 Playback Component may refuse to install the component in Lion. Apple states the component is unnecessary in Lion, however MPEG Streamclip still needs it. See this:

     

    http://support.apple.com/kb/HT3381

     

    To install the component in Lion, please download MPEG Streamclip 1.9.3b7 beta above; inside the disk image you will find the Utility MPEG2 Component Lion: use it to install the MPEG-2 Playback Component in Lion. The original installer's disk image (QuickTimeMPEG2.dmg) is required.

     

    The current versions of MPEG Streamclip cannot take advantage of the built-in MPEG-2 functionality of Lion. For MPEG-2 files you still need to install the QuickTime MPEG-2 Playback Component, which is not preinstalled in Lion. You don't have to install QuickTime 7.

    I don't mind paying for the mpeg component, but doesn't Quicktime Pro provide everything we need?

    No, Quicktime cannot handle 'muxed' files natively, hence the mpeg component.

    If he gets MPEG Streamclip and the QuickTime MPEG2 Playback Component on the Mac, he can convert to Apple Intermediate Codec directly and import into iMovie.

     

    If you convert to h.264 for him, he can import the h.264 into iMovie and let iMovie convert the h.264 into Apple Intermedidate Codec.

    16000 to 18000 kbps would be what I would consider to be an unconstrained bit rate approaching Apple Intermediate Codec, (i.e. minimal compression), but you could probably go lower with testing.
