Subtitles of the Movie

The final step in exporting a video from QuickTime or Windows Media to the Flash Video format, FLV, is to select the audio quality and you have quite a few options in this. Now, my video of the Himalayan Fair Dance Project was originally recorded in fairly high-quality stereo and I might elect to maintain that high-quality stereo in the FLV file. I can do that if I want to. First of all, just note that I have the Export Audio checkbox selected. That means that the audio track from my original file will get exported to Flash Video along with the video section of the video. I can adjust my audio settings in the Audio Tab of the Export Settings dialog. Now, here you might want to go back and review the earlier video in this course that examined how to extract audio files because that video discussed different quality audio and when you might use mono, stereo and various bit rates of audio quality. Here I've selected the highest possible quality stereo for my soundtrack; 256 kilobits bit rate however, is too high for an online video. Hardly anyone's equipment will even support that level of audio quality, meaning that I might as well select the CD-quality 96 bit rate. That will maintain a very high audio quality while reducing my file size. If I wanted to produce a smaller file size video, I might do that with a mono audio track and a 64-bit rate quality setting. That's acceptable for online audio. So it's your choice. You might in fact elect to create a high-quality version of your FLV file with a high-quality stereo soundtrack and let visitors to your website know that if they have a fast bandwidth connection, they can download that version. If they have a slower version, they might elect to go with the medium-quality mono soundtrack. So that's actually what I would do if I was producing this video for online distribution. So again, your choices are mono or stereo and different bit rates; the higher the bit rate, the higher the quality and as you can see in our estimated file size section, the higher the file size. When I go to a stereo 256 bit rate, I have a six megabyte file. If I go to a mono 64-bit rate audio, I have a video that's 50 percent smaller and will download correspondingly more quickly. So those are your options when you're selecting audio quality for a file that will be exported to Flash Video. Once you've selected your audio and video quality settings, click OK to queue the video up.
