I'm making a stop motion animation using iMovie. I just finished taking 200 stills from an hour or so of video. In the middle and at the end of the animation I put in video clips that had some audio I wanted to preserve. I hope this makes sense:

I wanted to cut some of the audio and tone down white noise in the clips. I started by extracting the audio from one of the clips and cutting the second half of it. I saved, then noticed that a bunch of empty space had been added to the end of the movie. The blue bar (I don't know what it's called) where the playhead is had also been taken over by the empty space. About half was white and unselectable. I didn't think it really mattered that much so I moved on to the next clip of audio I wanted to edit.

For this one I wanted to be rid of some awful white noise. I went to Audio FX and messed around with the Graphic EQ until I was happy with the noise reduction. I saved out of habit, and then realized that there was even more empty white space. Now the blue bar has been reduced to only a fraction of it's original size. As far as I can tell the movie hasn't been changed, but now it's almost impossible to drag the playhead to any position with precision and I can't see the clip breaks.

How can I get rid of the empty space? How did it get there? How can I avoid adding the white space in the future?

Thanks in advance!

am not sure if i understood what u are talking about ..but in case you're making an animation from still images you need to have a ratio of frame/sec its 25f/s for the PAL & 30f/s for NTSC you also should have a pixel aspect ratio of 1 so you can view the movie correctly

Smartypants and I figured this out together last night. iMovie has a bug in it that affects the way the timeline is displayed when you extract audio from a clip and then edit the audio within iMovie. When we removed the video clips with audio, the timeline display problem vanished. It didn't affect her movie at all, only the way the timeline was layed out, which could make for difficulties going back in to edit.

Write it all up to the limitations of a free program. iMovie is amazing, but for higher end work, you need to invest in a higher end product.
