I wasn't sure in which forum to post this question.


I need to output through my macbook's video port a simple photo slideshow (no audio, preferably a simple transition between photos) and while it is playing I need to add new pictures.


While this is happening I need to be able to use the computer (I need it to take the pictures (through a tethered camera) and print the new pictures)


I usually work in FCP and Premiere. But I assume I need a new piece of software to do this.


I have no idea where to even look for this.


Thanks in advance for any help!

    use two monitors or a monitor and a projector; one for the slideshow and one for Lightroom


    Create a slideshowin Lightroom then export as a QT video

    show the Quicktime in full screen then return to Lightroom to import using tethered feature of your camera

    thanks for the reply.

    But if lightroom has to export the slideshow as a QT video, how can I add pictures to the slideshow as I go? I dont want to render a new QT every 5 minutes and it wont be seamless as I have to stop the old video and start a new video

    We need the new pictures to seamlessly incorporate into the slideshow that is playing.

    I finally got an answer:

    two monitor set up, with your first monitor you can drop new pictures into the screensaver folder, while the second monitor is playing the slideshow and refreshes every 5 minutes:


    In applescript:


              do shell script "/System/Library/Frameworks/ScreenSaver.framework/Resources/ScreenSaverEngine.a pp/Contents/MacOS/ScreenSaverEngine -background &> /dev/null &"

              delay 300

              tell application "ScreenSaverEngine" to quit

      delay 1

    end repeat
