Thanks to Hongkiat.com for posting a nice review of Spotliter. Here are some excerpts from the post:
Insert Interactive Filters To Videos & Photos With Spotliter [IOS]
Apps such as Instagram allows you to add layers onto your photos. These type of apps are very popular due to the photo filtering functionality, allowing users to create photographs that have a certain type of look to them. Some developers have tried the same with video, where a filter is added to achieve different color effects.
Spotliter, however, goes beyond simple color filters. The free app provides the users more than the usual black & white or sepia filters. Spotliter provides interactive filters where users can create videos while manipulating the filter effects as they shoot them. Let’s check out the app, shall we?…
…The amazing thing about the app is that all of the filters can be applied and changed while the video is being recorded. You can use one filter one moment, then change it to another in the next second. It also allows you to pause your video recording, giving you time to switch filters before resuming.
