Edit what you've recorded, and make it shine. Brightly
Quik is a free photography and video editing app from GoPro. It's notable for providing a ton of features, comparable to a desktop photo or video editor, in a slick-looking and reasonably-fast app. It plays nice with other apps, and works well whether it's photos, videos or both you want to focus on.
Powerful enough for anyone
The list of features is tremendous, really. Even a review like this one can't outline everything you can do with this app, but let's start with the basics: you can edit and save video in both 7020p and 1080p (that's HD). You can remove unneeded portions of a video that you left recording to be sure you'd capture every moment, and you can splice together videos if you have enough content to make one great video.
Even these features, though, are made great here. For example, you can select a video link and the app will automatically cut and transition!
Then there's text overlays. You can choose from a huge variety of graphical styles, including fonts and filters, to make the text you can add to a photo or video work best. And in fact, you can use emoji, too. That's one feature you won't want to go without once you have it!
There is one thing to note. While you can make your own slideshows out of photos using this app, and you can even edit those photos to best improve that slideshow, there is a limit of 50 photos and 50 videos, so it can be a little tight sometimes.
Feature-rich and good-looking
Quik makes all of its functions easy to find, and looks good doing it. It matches up with Android and iOS better than operating systems, with sleek black trim and white font, but even if it doesn't match up, it still manages to look good. It offers a "video styles" function that lets you choose from 24 different presets, including transitions and other bits and pieces, that make it easy to put together a complete video from some shoddy footage you have lying around. The existence of video styles also means that if you're just using the program, they're a great way to learn. Beyond everything else it can do, this app also plays nicely with others. Using it, you can change a photo from cinema to square, making it perfect for Instagram viewing. As noted above, you can even add emojis for that extra bit of flair. And although it wasn't outright said, just implied: it functions fairly well as a photo editor as well as a video editor. This is truly a feature-rich app.
When the going gets tough...
Overall, Quik isn't something you want to use to simply sort videos and music. It's not even great for making slideshows, because of the photo limit discussed above. What it's great for is editing camcorder or phone video footage you already have. Adding music, cutting out or splicing footage, and adding transitions are all things the app does wonderfully. If you have a need for any of that, consider Quik.
