I have the task of creating a 5 minute multimedia presentation, and I'm looking for advice on scanning photos that will ultimately be part of an iMovie slideshow (which I will then burn as a DVD).  I thought I would scan at 1200 dpi in TIFF format.  Does anyone have any thoughts on scanning resolution?  I understand quality vs. file size tradeoff, so I'm looking for the settings that will look good on a modern HDTV in the 36 to 50 inch range.  Any thoughts?

    You can scan the photos at 300 to 400 dpi and it will be way more than you need. It can still be good to scan them at 300 to 400 dpi just  in case you ever want to print them out.

     

    iMovie will reduce them to 1920x1080, or about 2 megapixels.

     

    If you make a DVD, they will be reduced to 640x480 or about 0.3 megapixels.

     

    You really don't want to watch a DVD on a large screen TV. I would suggest using an Apple TV, or some TVs allow you to insert an SD card with full resolution photos.

    Are you saying not to watch the DVD on a large TV because all the mixdown will result in bad images?  The photo slideshows are going to be mixed with video clips.  That's why I was using iMovie.  Or should I bring the clips into iPhoto and create a slideshow that way?  Is that possible?

    The limitation is the DVD. All DVDs are standard definition.

    This is true whether you use iPhoto or iMovie. A DVD will be reduced to standard definition.

     

    You can achieve higher resolution by using an Apple TV, a Sony PS3, a BluRay burner and Player, and even YouTube supports 1920x1080. etc.
