Merge Multiple Video Clips in Order into One MP4

Nujiz Merge Videos combines multiple clips into a single video following the order you choose. Add your clips, arrange them before processing, then select the final frame dimensions and how differently sized source clips should fit inside that frame.

Arrange clips before merging

The order shown in the list becomes the playback order of the final video. Check the beginning and end of each clip and arrange them before starting, because the files are joined sequentially.

Handle different video dimensions

You can use the first clip ratio within the available size limit or choose Full HD, HD, vertical or square output. Contain keeps each clip fully visible, while Cover fills the frame and can crop edges.

Check joins between clips

Merging places clips one after another and does not automatically add cinematic transitions. After export, review the joins and confirm that order, framing and audio are suitable.
