JayCut

If you know something about Yahoo's Jumpcut, then you need no introduction to JayCut. This flash-based online video editor allows users to upload audio and video files before creating movies with background music or "mixes." If you're a beginner, JayCut comes with a free video-editing suite, including videos, images, and audios. What's better, users can directly export videos to PC, mobile devices, and YouTube. But on the flip side, JayCut users must register to unlock all functions. Even worse, JayCut is no longer accessible on popular operating systems like Microsoft Windows and Android.

Pros:

  • Very user-friendly.
  • Customizes videos with effects, transitions, music, and titles.

Cons:

  • Not available on some devices.
