    Are you sure about your information. My information is that JVC video files are standard MPEG-2 VOB files with Dolby Digital sound. This finds end in the .MOD extension. The companion .MOI file stores timestamp, versioning, and aspect ratio data.

    MPEG StreamClip will convert them into something useful.

    I am having the same problem!
    I am using FCP6, and have converted the .MODs to .MOVs using MPEG Streamclip, but the converted .MOVs don't come across correctly, and they make FCP crash.

    Export them from StreamClip as DV, then import into FCP.

    I have tried that, but my audio needs to be rendered, I get the red bar. I selected "yes" for changing the sequence settings to match the clip. Do you know what is up with my audio?

    Sounds like your project settings, StreamClip should be putting it out as uncompressed with the DV setting.

    Any idea how to correct it? The audio settings on my sequence is:
    48 kHz
    16-Bit
    Channel Grouped.

    I'd have to check, but IIRC, the DV audio will be 44.1 kHz ...

    Although, when I check on it, I found that the broadcast standard for DV is 48 kHz ... Luckily, there is an option in StreamClip preferences to use 48 kHz.

    Unfortunately, you'd have to reconvert all the files.

    EDIT: Looking into StreamClip some more ... it looks like it will not convert the source audio sample rate, unless you tell it to. So it would seem your camera is recording at 44.1 kHz, and StreamClip is just not converting it.

    Maybe that's what your project settings are?

    possibly, im using PAL-DV (australian format)... not that aware of the bitrates and whatnot. i used compressor to convert the DV *checks compressor settings*

    oh wow ok, my mistake. both NTSC & PAL use 48KHz.

    To use "StreamClip" software....

    Choose Demux to unscaled M2V and Aiff...

    If you have multiple files, use the Batch List function.

    Apparently the m2v produced has the sound in the file so you can trash the aiff file.

    Then you can edit your footage in Final Cut with no loss in quality. or play it in quicktime.

    I have read that visual Hub also works.

    Can FCP edit the MPEG2 file?

    Not directly, I don't believe. But MPEG StreamClip is a free, downloadable utility that can convert any mpeg 2 footage to a format FCP can use.

    Remember that mpeg 2 is not really an editing format; it's already somewhat compressed. Converting it back to DV or QuickTime can result in a slight loss of quality, especially if you will be recompressing it again after editing in FCP.

    But when you demux it, you are not converting it. You are merely splitting the audio and video streams. Which means the video is still encoded as MPEG2.

    I know that MPEG2 is not an editing format, hence the recommendation to convert to DV. Converting to DV will not lose any quality - DV is uncompressed.

    Going from compressed to uncompressed will maintain quality, it will not make it better or worse.

    There's a lot of misinformation in this thread.

    I think it's been cleared up now, but to clarify, DV audio should be 48kHz. If your source audio is 44.1kHz you should resample to 48kHz.

    DV is not uncompressed, but you may not notice any image degradation.

    What codec are these .mov files (.mov is a container, not a codec)?

    Thanks for all your help! Everything seems to be working now, except for the audio. Still needs to be rendered for playback.
    I really appreciate it!
