I can import and play D800 video into Aperture 3 without difficulty, but IMovie import of the same video files is very very slow and then crashes. 

 

10.7.4 and all software is up to date

 

Hardware is 15" Retina Display with 16GB RAM.

    Hi

     

    Me just interested.

     

    • Did You try to import into iPhoto

    And from Event's menu - iPhoto movies - import ?

     

    Did this too go very slow ?

     

    • Can the movie from Nikon D800 be opened in QuickTime Player

    and if so can it be converted to AIC or streamingDV ?

     

    If so - How will they import ?

     

    • If it opens in QT-Player - then open inspector [cmd+I] and read

    - Video Format/Codec: nnnnnnnn

    - frames per sec: yyyyyyyyyy

     

    What does they say ?

     

    Yours Bengt W

    I can be opened and played in Quicktime player

     

    H.264, 1,920 x 1,080

    Linear PCM, 16 bit little-endian signed integer, 2 channels, 48000 Hz

     

    FPS:29.97

     

    22.70 Mbit/s

     

    I have not tried it in iPhoto, but I can import and play the video fine in Aperture.  I have not tried an export from Aperture and then import into iMovie.

    Two reasons:

     

    1. The H.264 is not a good editing format, it is an industry standard for video compression. Taking advantage of today's high-speed chips, H.264 delivers MPEG-4 quality with a frame size up to four times greater.

     

    2. iMovie doesn't surpport 1080p format well. iMovie 11 may recognise it well, if the format is not iMovie's native format AIC.

     

    Conclusion:

     

    You'd better convert D800 H.264  to AIC (iMovie's native format) for smoothly editing on Mac.

    I would suggest that you right click on the iMovie event or on one of the clips in the event. If it offers to optimize, say yes.

    AVCHD is automatically optimized in iMovie but with h.264 you have a choice, because if you shoot h.264 in standard def sizes, most macs are powerful enough to handle it.
