Screencasting strategies. Composing the audio narration and synchronizing it with the video is, for me, the hardest part of the job. If you have prior experience with voice recording--I didn't--that should help. But even so you're likely to find that syncing your voice with the action onscreen is a real challenge. For short unedited scenes, you can do multiple takes until you get it right, or as close to right as is possible. For longer productions, though, I've adopted a very different work style. Initially I don't even try to narrate the scenes, I just capture them as video from which I trim all the fat. Then I dictate the audio for each scene in short segments. I save these sound clips in files, load them into the video editor, and arrange them to coincide with the onscreen action. What happens next is a kind of two-way negotiation between the video and audio tracks. In some cases I'll extend a frame of video to cover a crucial bit of narration. In other cases I'll rerecord a snippet of audio so that it covers some crucial action onscreen. It's tedious to trade files between Audacity and a video editor, and that's one reason I'm investigating more robust video editors with fully-integrated audio editing. But the shoestring approach is the only one I've used so far, and clearly it's viable. [Full story at O'Reilly Network] ... [Jon's Radio] 1:10:43 PM      Google It!.
