    This is weird.

    Usually, when I try to import a 25 minute HD .mpeg4 clip into iMovie HD it takes about 30 minutes to import.

    Now, I am importing a 25 minute clip and it is telling me it is going to take 3 hours to import. Whoa! I haven't changed any settings at all, so I am very curious as to what is causing this.

    Any ideas?

    Can anyone give me any ideas on why this could happen?

    What could make iMovie import a video about 5-6x slower?

    First thing I would do is reboot.
    After that check free disk space on your boot drive and make sure 50GB+ are free,

    If that doesn't work, convert the video to the AIC codec with MPEG Streamclip before importing.
    ( which is probably better anyway than trusting iMovie to import )

    I have about 20-30 GB free on average. I feel like I had that much when it was importing quicker before.

    I will try deleting some stuff.

    Another iMovie brain buster ..

    I export an EyeTV file directly to an iMovie HD file to make it simpler. However, when I try and edit and add transitions or effects on clips everything turns black.

    Okay ..

    So I export it natively with H.264 and use that .mpeg4 file to import into iMovie - of course like my original post states it is importing way too slow. But when it finished, I can edit the clips with transitions and they all work.

    How is that possible?

    Do I need to re-install iMovie?
