Particularly intensive is the process of rendering your finished product into a standard video file that will by playable on the target device of choice, be that an HDTV, a laptop, or a smartphone. Most of the software can take advantage of your computer's graphics processor to speed this up. Be sure to check the performance section in each review linked here to see how speedy or slow the application is. In rendering speed testing, CyberLink and Pinnacle have been my perennial champs.
We used each program to create a test project, using identical elements for each one. We timed how long it took each program to import our test video files. Then we timed how long it took us to make our test video. We finally recorded the time it took each program to export the final video. A program that performs even marginally faster can save you dozens of hours.

One of iMovie’s most coveted features is its green-screen, or “chroma-key” tool, which allows you to place your characters in exotic locations—Hawaii, say—at a moment’s notice. Want to overlay the scene with “Somewhere Over the Rainbow”? iMovie ties directly in with iTunes and GarageBand, so you can easily implement custom tracks and sounds. When your movie’s finally ready to ship, release it into the wild using iMessage, Facebook, YouTube, or any other of iMovie’s succinctly connected platforms.

All video editors should, at the very least, have some combination of familiar features like a viewer or playback window, library, timeline, and access to transitions and effects.
We combined a text opener with five clips linked by a cross-fade-type transition into a 2.5-minute video shot at 60 frames per second, and rendered the projects to the MPEG-4 format at 720p. We timed rendering at both 60 fps and 30 fps. We adjusted settings to take advantage of hardware acceleration for all tests whenever possible, setting them in either the preferences or the rendering controls for the best speeds. Apple’s iMovie, the lone Mac-only app, is not included in the timed comparisons.
