Merge videos into one

Build the complete sequence on a visual timeline: reorder clips, trim each take, set its framing, rotation and sound, then choose a different transition at every join. Preview the final timing and canvas before one private local export.

Joining clips is where most short videos are actually made. This is a visual merge timeline rather than a simple concatenation: reorder clips, trim each take, set its framing, rotation and volume, choose a different transition at every join, and preview the whole sequence on one canvas before a single local export.

Everything resolves to one canvas

Clips from different sources rarely share a resolution, aspect ratio or orientation, and the output has to be one consistent video. Set the canvas first — widescreen for a standard upload, vertical for a feed — and then decide per clip whether it fills the frame, which crops it, or fits inside it, which leaves bars. A vertical phone clip dropped into a widescreen sequence is the case that always needs a decision: cropped to fill it loses the top and bottom of the subject, and fitted it sits between two black columns.

Transitions, and when not to use one

A hard cut is the default in professional editing because it is invisible when the material is coherent. Reach for a transition when there is a real gap to bridge — a change of location, a jump in time, the boundary between sections — and let everything else cut. Crossfades in particular are worth rationing: used at every join they read as a holiday slideshow and blur the moments either side of them. Keep them short, around a third to half a second, so the transition does not become the thing the viewer notices.

Matching levels before you join

Clips recorded at different times almost never match in loudness, and a merged video where every join changes volume is exhausting to watch. Set per-clip volume on the timeline so speech sits at a consistent level throughout, and check the joins specifically rather than the middle of each clip. If the difference is large — a phone recording next to a proper microphone — run the pieces through the normalizer first so you are balancing tracks that are already in the same range.

Questions, answered

Can I merge videos with different resolutions or orientations?

Yes. Choose the output canvas and then decide per clip whether it fills the frame, which crops it, or fits inside it, which adds bars. Mixed portrait and landscape sources always need that choice.

Should I add transitions between every clip?

No. Hard cuts are the norm and read as invisible. Save transitions for real changes of place or time, and keep them short — around half a second.

Can I trim each clip inside the merge timeline?

Yes. Every clip has its own in and out points, framing, rotation and volume, so you rarely need to prepare the pieces separately first.

Why does the volume jump between clips?

Because they were recorded at different levels. Set per-clip volume on the timeline, or normalise the sources first if the difference is large, then check each join by ear.

How many clips can I merge?

There is no fixed cap, but the whole sequence is processed on your device, so long timelines with many high-resolution clips take longer and use more memory.
