Set Audio Output Options

Now that your SWF options are set, click the "Audio" tab. On the upper let of this window you will notice the "Input Audio Properties", which describe the features of your source audio.

Immediately to the right, you will notice the "Output audio options", where you may choose the way your source audio is encoded. There are three audio options, which you can set: sampling rate, bitrate, and stereo/mono.

• Sampling Rate: This is the frequency at which the audio is encoded. This is measured in Hertz (Hz). The higher the frequency, the less "tinny" your audio will sound, and the larger your filesize will be.
• Bitrate: This value reflects the amount of information used to store the audio in the output SWF. This is measured in kilobits (1000 bits = 125 bytes) per second (Kbps). Higher bitrates lead to higher quality audio AND larger SWF filesize, but do not significantly affect RAM consumption on the viewer's machine. 128 Kbps MP3 audio is generally considered to be equivalent to CD audio.
• Stereo: SWF can support stereo audio. If you wish your audio to be encoded in stereo (assuming the source is stereo), select this box. This setting does affect file size. At lower bitrates, a setting of mono will result in better quality audio.

Choose Audio Intermediate Files

On the bottom half of the Audio tab, you will see the "Output audio export options," where you may choose whether to save a WAV and/or MP3 of the audio track along with your SWF output, by checking the appropriate box.

By checking either box, the output file name is the same as the output SWF, such as my_movie.WAV. To save the audio to a custom name, select "Filename" and click "Browse" to select the directory and the desired filename.

Please note that choosing either ".WAV" or ".MP3" does not remove the audio track from your SWF. You might want to save a WAV, for example, in order to import the audio into Macromedia Flash (Flash will not import the soundtrack of your Flix-generated SWF because Flash can not import MP3 even in SWFs).

Set Output Frame Options

Now that your audio options are selected, click the "Video" tab. On the upper left of this tab you will notice the "Input video properties", which describe the unalterable characteristics of your source video. Immediately below, under the heading "Output frame options", there are two settings:

• Average image quality: This value, set on a scale of whole numbers from one to 100, reflects the image quality for each frame. You may think of this like saving a .jpeg. The higher the number, the better the image quality, and the larger the file size. This setting does not significantly affect client-side RAM consumption. You may have to experiment to find your ideal setting. We recommend keeping your average image quality below 80%.
• Image smoothing: This setting is either on (checked) or off. This feature can be used to compensate for some of the pixelation characteristic of photographic image compression. This feature can be more useful at lower image quality percentages (when pixelation increases) or if you apply "Custom SWF dimensions" and stretch your image (see next step).
