InShot Editor is a photo and video editing app especially designed to improve the final result for any video you want to upload to your Instagram. It also lets you improve pictures and, of course, save your edited videos to your device's memory.
In the video editing section you'll find tons of interesting tools. For example, if a video has been recorded in vertical format, you can choose to center and enlarge the image or create a pretty blur effect behind the image. You can also apply filters, insert text, add music, and even add emojis. Once you finish, just choose the quality you want to save your video in.
For the image editing you'll also find lots of options. You can crop the image, apply more than a dozen different filters, alter the brightness and saturation, add hundreds of stickers, and much more. In short, you can give any picture an entirely new look.
InShot Editor is a powerful image and video editor that, despite being geared mainly toward creating content for Instagram, lets you touch up videos and images to save them straight to your device's memory.
