Compression Options for QuickTime Video

QuickTime is a very flexible video format which allows you to use more
Compression options than can be easily documented. For example, you
can create a QuickTime MOV that uses the same kind of H.264 compression
that you find in MPEG4 files.

For more information on the various types of compression and options you
have for creating QuickTime videos, please see the documentation for
QuickTime.

Resolution and Framerate

Once you have chosen your Format and Compression you have two
remaining options to select for your video. The first is the resolution that
will be used for the video and the second is the framerate that will be used
for playback.

The Resolution you select is entirely up to you. Remember that higher
resolution videos will look very good but will be much larger than lower
resolution video. If you’re planning to view this video online it’s best to
keep the resolution relatively low, typically under 640 x 480. Videos that
will be distributed on disc or downloaded can be much larger. Use
whatever resolution you feel works best for those, though it’s not
recommended that you make your video higher resolution than the images
you have used to make the show.
The Framerate is, as discussed previously, the number of images that are
displayed in sequence every second to make the video move. Higher
framerate makes the video appear to play more smoothly but can
dramatically increase the size of the video.

Certain video files also have limitations on how high the framerate can be
set. For reference, most TV shows and films use a framerate of 29.97.
