Modern apps and powerful smartphones have made editing photos easy. But when it comes to editing videos — especially videos set to music — it's still pretty difficult to come away with an acceptable result. Triller aims to change this by starting with the song instead of the video. To use it, you open the app, select a song either from your library or from the app's featured tunes, choose the portion of the song you want to use, and shoot multiple takes that last the whole duration. From there, you can add filters to the video before the app's intelligent algorithms take over, automatically stitching together smaller clips from each take to create a video that should mimic the output of a professional editor. Note that we said editor, not film crew, so the quality of the clips is still very much in your hands.
