Prezent offers a new and clever twist on portfolio apps: It seamlessly integrates both still images and video into one presentation showpiece. While that may not seem so hard for editors, for novices it's incredibly useful, and most apps we've tried are either strong on video or strong on stills but almost never both. Once you've loaded up multimedia content, place photos and videos side by side. When a video pops up, it begins rolling immediately, giving the portfolio a fluid feel – and you can even combine video within a still image. The effect is pro-style production – but it will be accomplished by an amateur. [$8.99; iOS]
