| The first in my new series on special effects tutorials for iMovie 09 and 11, this one featuring muzzle flashes, blood hit, and explosions. Troubleshooting: - Make sure you have NOT checked "optimize video" when importing - If you are having trouble with the Picture in Picture, check out my response video below - Ensure your Picture in Picture setting is not set to "fit in frame" PRIOR to inserting your footage - If your footage inserts transparent and looks right when you scrub through it, but doesn't play in real time in iMovie, don't worry, it will work fine after export - The most common issue is that the footage isn't actually pre-keyed |
