Video Toolbox is a video editor app that provides a set of tools to do the simple things you want with videos on your Android phone or tablet: rotate, trim, flip, resize, and convert.
Try before you buy with the demo version. It's identical except output videos contain a watermark: http://androidideas.org/videotoolbox/trial/google-play
Supports editing all media formats created by Android camera (camcorder) apps as well as some additional formats.
Please disable task killers; they can interfere with a long rendering process.
Video Toolbox isn't a traditional linear video creator with a timeline, although it allows you to simply edit and convert your videos. It provides a toolkit containing most of the functions that you’d want in a mobile setting (rotate, etc.) with an interface that makes sense in on a small form factor.
About the tools
Rotating a video clockwise or counterclockwise, rotation by 90, 180, or 270 degrees. Rotated video will have its width and height flipped due to rotation.
Cut a clip out of a film. Trimming is done by start and end times, allowing time to be trimmed off the beginning, end, or both.
Change the resolution (width and height) of the video frame. Resizing is proportional by default but resized video can be any aspect ratio.
Flipping a video horizontally or vertically. If a video is already flipped from the rotate tool, it will flip again, essentially neutralizing it.
Allows you to choose the video and audio quality in terms of the bit rate (kb / sec). Often used to shrink the file size. Shrinking will allow easier sharing over Email, MMS, etc. Shrinked video may be lower in quality.
No audio tool:
Removes the audio track.
Not a tool that you add like the others, but converting to another format is as easy as picking a different extension when saving.
Helper for sharing videos (either created with this movie maker app or already on your phone) to YouTube, Facebook, Gmail, Messaging, etc.
