Tweaking the audio settings is much simpler. A compressor that yields excellent results is the IMA 4:1 compressor. You then have a choice of sample rate (between 8000 and 48000 kHz) and sample size (8 bit or 16 bit), and between mono and stereo. Again, the better the quality of the sound, the bigger the QuickTime file will be. Mono at 16 bit and 32 kHz is a good compromise, but you may decide that stereo is important to your viewers’ experience.
If you want users to be able to start watching the QuickTime video before it has all been downloaded, check the “Prepare for Internet streaming” box and select “Fast start” from the menu. Using the fast start option is highly advisable, because without it users will not see anything apart from the QuickTime logo until the whole video has downloaded, and many people can become discouraged and give up before your video has started playing.
Click on OK. This will close the settings box. Type in a file name for your video and click on “save.” The QuickTime encoder will start compressing your video.
You will probably have to repeat the process several times with different settings in order to find the best compromise between frame size, file size and image quality .
