Order, trim and join
Add the clips you want to join in any order, then drag them into place or use the arrows. Each clip has its own From and To times, so you can cut a slow start or a shaky ending without opening a separate editor. The total length updates as you go.
Clips from different phones and cameras
Clips rarely share the same size. The finished video takes the size of the first clip, or one you choose, and every other clip is fitted to it. Add bars keeps each picture whole with bars at the sides or top and bottom; Crop to fill fills the frame and trims the edges instead. Sound from every clip is kept and matched, and clips without sound get silence so the timing stays right.
Crossfades and the finished file
A crossfade blends the end of one clip into the start of the next, picture and sound together, and shortens the total by the length of each fade. The result is saved as an MP4 that plays almost everywhere or a WebM for websites. Every frame is processed by your browser, so longer videos take a little while, but nothing is uploaded and there is no size limit beyond your device's memory.
