Hi guys,

I finally got my cable today and I hooked in my Mini DV camera into my Macbook Pro. Playing back, the video looked fine, but when I click import, the video was choppy and after it was done importing, the video was in like 1 second clips. Anyone help?

Well then I tried later on in the tape and it recorded 28 seconds all in one piece. IDK if this makes a difference, but the one I described before was at the very start of the tape, but I wouldn't think that matters. So IDK.

The placement on the tape shouldn't matter.

If you mean it was choppy DURING the import, I wouldn't worry about that. If it was choppy after the import, then yea, there is a problem. During import the priority is to get all of the frames onto the hard drive.

iMovie recognizes where you started and stopped between recordings and uses that information as split points to create separate files.

What software are you using?

Are you importing to your startup (internal) drive?

I am also having this exact same problem. I have mini dv tapes from 2006. When I try to import this video to my startup disk of my 2009 MBP using imovie 09', the video preview AND playback (after import is finished) is choppy and plays in 3-5 second intervals. There is also horizontal bars through the frame which comes and goes. This is my first time trying to import video to my MBP. Hope someone can help.
Thanks

RE: Horizontal lines

First remember that interlaced material is not drawing a full frame at a time. It is only half a frame so you will notice horizontal lines. When producing output for the web or a computer, you should de-interlace the output. I use the QuickTime export for that. If you are exporting to create a DVD via iDVD, then the de-interlacing step shouldn't be needed since DVDs are interlaced material.

The other thing I can think of is a worse case scenario. iMovie 7,8 and maybe 9 have an issue with DV interlaced material. I found the problem being discussed on this very long thread at Apple; Apple - Support - Discussions - DV video quality ...

A possible solution to that problem was posted here; The iMovie Output Project

As for the choppy or short clips, I don't have an answer. Potentially your import is not clean and is dropping frames. It is best to capture to drive other than your internal one, although I have captured to an internal one with success. I could speculate a little further but don't want to write a guessing book.
