transitions between A and B roll, iMovie 10/Mac
Can you add transitions between a video and pictures added to an iMovie project as B roll? I dragged photos from iPhoto into the B roll location above my video, and it works as cut aways. Is it possible to have the transitions as dissolves instead of cutaways, or do I have to insert the photos into my A roll to add transitions? I'm guessing the second, but thought I'd ask before giving up on my idea.
The video is a fashion show video and there is audio underneath. I don't want to lose the sync of the audio to the original video, but when I insert the photos into the movie A roll, I get these periods of silence during the photos. I suppose I can also detach the audio, but I was having trouble timing/ setting the ins and outs for the video clips after inserting the photos.
I realize iMovie doesn't have a "real B roll,"if it did there would be two tracks for video at all times. That adding photos as a cut away is a B roll type thing, right? Am I trying to do too complex things with this, and would be better to switch to a higher end video editing app?
