QuickTime

If you've specified the image type to QuickTime, you can specify the compressor, playback rate, and number of frames in your movie.

Time-lapse Settings

The time-lapse settings determine how many frames will be in the final movie. The Movie Length is the interval as defined by the interval settings and is how often a movie is saved to disk.

Interframe delay = Movie Length / Frames

Frames in Movie = Movie Length / Interframe Delay

The more frames that you have in a movie, the large the movie file will be. A balance must be made between the number of frames, the file size, the image size and quality settings.

The compressor (codec) is what is used to compact the images into a small movie file. Only some compressors are available on the majority of platforms. Photo-JPEG is the default compressor for SiteCam. Cinepak provides good results but uses a lot of CPU time (usually more than 1 second to add a single frame of video). For the widest cross-platform audience, choose one of the following compression codecs: Cinepak, Photo-JPEG, Graphics, Animation, Video, Photo-CD, Intel Indeo, or None. When QuickTime for Windows 2.5 is used, Component Video, M-JPEG-A, and M-JPEG-B is be supported. Consult the QuickTime documentation at the Apple Quicktime site for more information.

The playback rate determines how many frames/second will be displayed when viewed in a web browser or using a QuickTime movie player.

Flatten for internet use when you are posting movies to the web. Flattening a QuickTime movie takes out all the MacOS specific information and puts it into a file format that is readable on all platforms.
