Macworld has now posted my review of iMovie ’11. I gave it 4.5 mice, up from the 4 mice I gave iMovie ’09 largely due to the inclusion of audio editing features that have finally caught up (and slightly exceeded) those of the late, lamented iMovie HD 6.
Putting together a video last night drove that home: I was able to isolate some sections where the shutter click from my still camera was overwhelming. To do so, I selected the portion of the audio where a spike appeared in the waveform, and dragged the Volume bar down to zero. However, that left a noticeable gap of silence.
So, instead I selected the clip, detached the audio, then trimmed it down so that just a section of background noise was active. The video clip is automatically muted when you detach the audio, so I un-muted it, placed the background noise clip over the shutter click, and lastly reduced the volume where the spike occurs. Here’s the finished product:
The green waveform at the bottom of the screenshot belongs to the background music track; I’ve reduced the volume to about 40 percent so it isn’t competing with the audio from the video. (I tried turning on ducking for the video clips, which reduces other tracks automatically, but doing so negated the purple background noise fragment clips. It was easier to adjust the background track volume where I needed it.)
Here’s the finished video:
