Here's a video I made with Pinnacle Studio 3 for iPad.
It has lots of short clips matching the music. It's not a great video but even with limited footage you can nearly always produce something better than expected thanks to Pinnacle Studio for iPad.
Using the new features of Version 3:
The new speed tool was used to slow-mo a few clips to complement the quiet passages of music. This automatically makes the clip silent which suited nicely but if I wanted the clip sound I would have separated it first with perhaps a bit of moving and trimming.
Keep length was always on because I was doing this towards the end of the project and trying to keep in synch with the music. It helps if the original clip has plenty of length to allow you to adjust the position of the selection. You do need to be very wary of going near the ends of the clip if you're using transitions.
One clip was modestly speeded up, again to go with the music. In many scenes subtle speed changes work well for this and are almost unnoticeable whereas more dramatic changes have a more comic effect.
One clip showing a slow pan and no moving objects was slowed slightly to allow some slight stabilising. You could also use the freeze frame but will lose the pan. I sometimes take a screen shot of the full screen video and re-import it as a still. You can then pan and zoom the scene.
I also used the speed tool on 100% to adjust the previously selected part of a clip forward or back in the clip without changing the resulting length. This is a very handy way of getting the best part of a clip. Previously I would have had to note the length then adjust the trims handles consecutively whilst trying to keep the length the same. Again you need to be wary of cutting into a transition.
I was a bit lazy and didn't bother using the precision editor to get the clip timing exact. You will notice a few clips that freeze in the transition. I should have checked every transition with the precision editor. It's a great tool to polish your video.
Finally the new enlarged thumbnails makes stealing a clip from a similar scene earlier or later in the video much easier because it is so much easier when moving it a long way in the storyboard to identify its new location.
