Are my videos uploaded anywhere?

No. Video Edit decodes, joins and re-encodes entirely in your browser, so the footage never leaves your device. There is no account and nothing is sent to a server, which also means there is no upload wait however large the files are.

Is there a watermark on the exported video?

No. The exported MP4 carries no watermark and no branding.

What video files can I use?

MP4 and MOV, which covers what phones and most cameras record, plus anything exported from Emaki Studio. Very large or unusually encoded files may not open - if one is refused, re-exporting it as H.264 MP4 will fix it.

How long can the finished video be?

The file is assembled in memory before it saves, so there is a limit: around 90 seconds on a phone or tablet and around five minutes on a desktop. The tool tells you when a timeline is past it, and trimming a clip brings it back under.

Can I join a portrait video to a landscape one?

Yes. Choose the output shape you want and each clip is scaled to fill it, cropping whatever overflows. Mixing orientations always costs something at the edges, so pick the shape that suits most of your footage.

How to put two videos together

Joining clips usually means uploading your footage to a site you have never heard of, or installing something. The Emaki Studio Video Edit tool does it in your browser: trim each clip, put them in order, choose a transition, and export one MP4 with the sound mixed. Your footage never leaves your device. Here is how.

1. Open Video Edit and add your clips Open the Video Edit tool and add two or more MP4 or MOV files. Each one is read straight off your device - nothing is uploaded, so even a long recording starts immediately instead of waiting on a transfer.
2. Trim each clip to the part you want Every clip gets a Start and End control. Drag them to cut off a shaky opening or a long tail. The trim never touches your original file, so you can move it back at any point.
3. Put the clips in order Use the up and down arrows on each row to arrange them. The order in the list is the order they play, and the total length updates as you go.
4. Choose what happens between them Pick a straight cut, or a crossfade, dip to black, push or wipe. A transition overlaps the two clips, so it shortens the finished video slightly - and the audio crossfades with the picture rather than cutting abruptly.
5. Pick a size and export Match the first clip, or choose 9:16, 1:1 or 16:9 - useful when the finished video is going somewhere with a fixed shape. Then export an MP4. On a phone the share sheet opens so you can save it straight to Photos.
