After editing and finishing a video project, I sent it to idvd and did all the theme, music and scene selections, etc.  Everything seemed to go

great until it finished burning.  The video was very shaky and jaggy.  What could cause this?

iMac, Mac OS X (10.6.8), using imovie to idvd

    There are more than one thing to this.


    A. a DVD can never be any better than interlaced SD-Video (as on old CRT-TVs) - it's in the DVD Standard - whatever program used. Your Mac screen ar far more better.


    The video was very shaky and jaggy.  What could cause this?


    Shaky - one very common origin to this is that iDVD is set to make PAL (25fps) or NTSC (29.97fps) (only choice there is as DVD Standard set's it) - and iDVD is feed 24fps or 50p or 60p or other more modern formats. OR that one tries to do a NTSC-DVD from PAL material or other way.


    iDVD are not good in this frame rates conversions (fps) - So I use JES_Deinterlacer to do this and although it's free on Internet it does this conversion even better than pay-applications.


    Jaggy - usually affects photos most and are due to the use of


    • iMovie'08 to 11 - as they don't export OK over to iDVD but discard every second line in the picture - Better is to use iMovie HD6 or FinalCut as they can deliver 100% over to iDVD


    • "Share to iDVD" was used - in any version of iMovie HD6 to 11 same problem. I do in iM'08 to11 - "Share to Media Browser" - and as LARGE - NOT HD or other resolution as this too degrades the final DVD result
