iOS: Videohance is a new video editor that lets you add filters and effects to your videos, adjust white balance, add light leaks, adjust exposure or contrast, and more. The best part is that it can do it all while you watch your videos so you can see the changes immediately.
Once installed, you can take any video you've recorded with your phone, iPod Touch or iPad and tweak it to fit your style. There are lots of Instagram-style filters you can overlay, and you can try them all out as you play the video. If you would rather edit your video in a more nuanced way, you can adjust the white balance, contrast, colour temperature, exposure, brightness, highlights and shadows. You can even add audio and edit the video itself by trimming sections or cutting out parts you don't want. If you prefer, you can tweak sections of the video or overlay multiple effects.
When you're done editing, you can export the finished product and save it locally, or upload it to YouTube, Tumblr, Instagram, Facebook and a number of other services. The app is robust and works well on even small phone screens, which is useful considering video editors for mobile devices can be difficult to use. The video above gives you a quick walkthrough of some of its features. If you want to try it, hit the link below -- it's $3.79, and more filters and tools are available via in-app purchase.
