Should none of the other sharing options be sufficient for your needs, you may want to consider exporting your slideshow to a custom video file. Please note, that this is not for the faint of heart, as quite a bit of QuickTime knowledge may be required to obtain good results.

Select Custom Video... from the Share menu. An assistant appears that guides you through steps necessary to create a custom QuickTime or MP4 movie.

Select the rendering, video, and audio options for your exported movie. Rendering options are video size (width and height), framerate (frames per secoond), and a few options settings. Video settings are codec and file format, plus a few codec dependent values like bitrate. Audio settings are again codec, sampling rate and codec dependet values like bitrate or bitdepth.

If you only specify the width or the height in the render settings, the missing value will be calculated automatically. If you specify both the width and height, then this size will be used, even if the aspect ratio does not match the aspect ratio of your slideshow. In this case you will get radio buttons that let you choose whether you want to letterbox or crop your slideshow to make it match your export movie size.

If you specify both width and height, you also get the option to enter a custom pixel aspect ratio, which may be necessary if your exported movie is indented for video output, which often requires non-square pixels (anamorphic formats).

Frame rates between 1 fps and 60 fps are supported. Using a higher framerate improves quality of motion, but rendering times are significantly increased.

There are several video and audio codecs to choose from and each is slightly different. A discussion of each one is beyond the scope of this documentation. Please note that some prior knowledge with video compression settings is required to achieve good results!

Specify where the exported QuickTime movie will be saved. FotoMagico will suggest a reasonable filename, but you can also specify your name and location. Please make sure to select a folder that has enough free disk space and write permissions.

Once you click the Start button the exporting will begin. Exporting is usually done in 4 steps: Preparing, rendering video, rendering audio, and compressing video. A progress bar for each step is displayed at the bottom of the assistant. Depending on the duration of your slideshow this can take quite a bit of time, so you may want to do this overnight.

The slideshow has been exported to a QuickTime or MP4 movie file. You may now further process it in QuickTime Player or other video editing applications like iMovie or Final Cut Pro. Click the button 'Open in QuickTime Player' to open the movie or click the button 'Reveal in Finder' to locate the file.
