Can I merge videos of different sizes?

Yes. The frame uses the standard ratio closest to the first video (such as 16:9 or 9:16); the other clips are scaled to fit, with black bars rather than cropping. To use another ratio, open the full editor and change the canvas ratio.

Can I add transitions?

Yes. Tick “Crossfade between clips” in the panel and every cut gets a crossfade. For others — dip to black, slides, zoom and more — open the full editor, which has 13 transitions with adjustable duration.

How many clips can I merge at once?

There is no set limit. More clips and a longer total length just mean a longer export; how much your device can handle depends on its memory.

Will different frame rates cause stutter?

On export every clip is re-rendered at one frame rate (the project’s by default, 30 fps for a new project), so mixed frame rates do not cause glitches. A low-frame-rate clip will not become smoother, though.

What if the clips are at different volumes?

Each clip keeps its own sound and they play one after another, but volumes are not evened out automatically. Open the full editor and select a clip to set its volume individually (0–200%).

Merge videos into one

Join several videos in order — different sizes are fitted automatically.

Join several videos into one for free: drag clips on the timeline to set the order, tick a box for crossfades, and different sizes are fitted into one frame. No upload, no sign-up, no watermark.

Joining a few clips into one complete video is the most basic and most common step in editing. Clips shot at different times or exported from different devices can all go together.

Pick several files at once and they are laid out one after another on the timeline. If the order is wrong, drag clips on the timeline to swap them — the timeline order is the export order. Need more footage? Click “Add more”.

Different sizes are fine: the frame follows the first video’s shape, and the others are scaled to fit inside it with black bars where needed — nothing is stretched or cropped.
