Creating QuickTime movies You can save a Presentation in QuickTime movie format, so the doc- ument’s slides become the movie’s frames. To save a Presentation document as a QuickTime movie, choose File > Save As and select QuickTime™ Movie format. Click Save. Select options in the Export Options dialog box and click OK. Seconds Per Frame The playback duration in seconds for each slide (frame) in the movie. The actual playback speed can vary depending on the system capabilities and movie file compression. Colors The color depth for the movie file. More colors result in larger file sizes. Maximize Select an option for compression used in the movie file: •   Animation Quality makes slide transitions as smooth as possible at the expense of image resolution. •   Image Quality uses high image resolution that might slow down the animation. •   Compression keeps the file size to a minimum, at the cost of lower image quality. Playable on non-Apple computers Makes the movie file compat- ible with QuickTime for Windows. Saving files containing movies If you save a document that contains a QuickTime movie object, Canvas updates the link to the movie file. If it can’t find the movie file, Canvas asks you to locate the file. In the directory dialog box, select the file and click Open. If you can’t locate the file, click Cancel to continue saving with only the movie’s “poster” (preview) image. Using Tag Image File Format (TIFF) Tag Image File Format is a high-resolution raster image format. Can- vas supports both RGB and CMYK TIFFs. Although TIFF is a com- mon format, many TIFF variations exist. Different resolutions, color systems, previews, and compression schemes make the format flexi- ble, but can cause compatibility problems. When you save TIFF files, you can choose compression options in the Export TIFF dialog box. Various compression options are avail- able, depending on the mode of the image you are saving.
