CONCLUSION

Digitizing Video, continued

Once you've decided on which compression you want to use, select it in the Movie Capture / Video Input dialog box. Then set your audio preferences in the Movie Capture / Sound Input dialog box. See the section on the Audio How-to page if you need help. Hit Record in the Recording window and you'll be in business. If you don't have much memory or much disk space, you won't be able to record very much! (Hope for seconds, not minutes.)

After you've recorded you clip, a Clip Window will open. Save the clip so you can work with it in Premiere. Once it's been saved, you can begin a New Project and Import the clip. (The easiest way to import the clip is to simply drag it into the Project Window.) From there, you can drag the clip from the Projects Window onto the Construction Window. (This is the same thing we did when working with the audio clip.

Once you've got the movie in the Construction Window, you can save it as a movie using any compression format and audio format that you wish. (Keep in mind that you'll never be able to get better quality than you already have. If you digitized the sound at 11 Hz, 8-bit Mono, you aren't going to improve it at all by saving it in 22 Hz, 16-bit Stereo. You'll just waste disk space and download time. The same holds true for video, except that if you compress the video a second time, you might lose even more information.)

Rather than typing it all over again, refer to the section on saving your audio file as a Quicktime movie for information on how to save your animation file.

Embedding Video in HTML Files

The concept is identical to that of embedding audio files. (Especially if your audio files are Quicktime movies.) The key is to make sure your browser has been told what to do with animation files. In Netscape, this is done by opening Options / General, choosing Helpers, and then telling Netscape what to use for your particular file type. Again, make sure you let your users know what kinds of files you have embedded and what they can use to display them.

Linking to an animation file:
Use a standard anchor link to point to an animation file. Your viewers will have to set their browsers to use an appropriate helper application to open the files. Here is an example. The code used to create the link is:
<A HREF="video/duncan5.mov">example</A>
and my Netscape browser is set to use the Quicktime Plug-in to open the animation file in a blank browser window.

Embedding an animation file
The animation types page uses the Netscape extension <EMBED> to embed the a movie file in the web page. (The morphing man/bug animation.) Again, my browser has the Quicktime Plug-in installed and Netscape has been set to use it when opening Quicktime files.

(To set Netscape to use a particular plug-in or application to read a certain file type, open the Options menu and select General. In the General dialog box, select Helpers and then select the appropriate tool to open the appropriate file type. See your browser's documentation to see how to set helpers for your particular browser.)
