The visible order becomes the finished video order.

The first release joins matching clips without re-encoding, so it is fast and preserves source quality.
A weekend away, something you made, a night worth remembering. Use the MP4 Video Merger to bring your favorite moments together in the order you choose.
The train ride, a cafe by the sea, the last sunset of the trip. Bring the moments from your camera roll into one travel video. Choose compatible MP4 clips, put them in the order you remember, and let the MP4 Video Merger turn separate files into a keepsake you can watch from start to finish.
From a lump of clay to the finished bowl, each stage tells part of the story. Merge your prepared process clips into one MP4 video so viewers can follow the work in sequence. The MP4 Video Merger keeps your chosen order and original encoded quality, whether you are sharing pottery, a recipe, or a studio project.
The quiet before the doors open, the first song, the crowd at the encore. Combine your favorite concert clips into one event recap. Arrange compatible MP4 footage around the moments that matter, then use the MP4 Video Merger to save one continuous video to send to friends or keep for yourself.
Illustrative scenes. The merger joins your existing clips; it does not generate new scenes or add transitions.
Three simple steps
Turn a sequence of short generated clips into one continuous story, entirely inside your browser. Use this free MP4 Video Merger to assemble your selected takes after generation. Preview the sequence before you merge, then save the combined video.
Choose 2–20 compatible MP4 clips. Each file is checked locally before it joins the queue. Start with MP4 exports from the same video settings. The MP4 Video Merger accepts up to 1 GB in total and reports incompatible files before you merge.
Preview, remove, and move clips until the visible queue matches the story you want to tell. Put the opening first, then check where each video ends and the next begins. The merger follows your chosen order; it does not trim pauses or add transitions between scenes.
Join matching clips in your browser, then preview and download one continuous MP4. Keep this tab open during the merge. Watch the finished video through before saving it, especially at the joins. Download the MP4 before clearing the result so you have a copy outside the browser.
Good to know
Use MP4 clips with H.264 video, matching dimensions, orientation, and profile. Audio can be absent; when present, every clip needs matching AAC settings. An MP4 extension alone does not guarantee compatibility. If the MP4 Video Merger reports a mismatch, export the affected video with matching settings in your editor and add it again. The merger does not resize mixed portrait and landscape footage.
Matching encoded tracks can be joined without a long transcode or a second compression pass. The MP4 Video Merger preserves the encoded video and audio rather than sharpening a soft source. Merge only the takes you want to keep; existing watermarks remain in the MP4 output. This merger adds no watermark of its own.
Video bytes stay on this device. Temporary output uses private browser storage until the result is cleared or the site's data is removed. The MP4 Video Merger does not upload your selected media for processing. The page still uses the site's shared services, so local video processing does not mean the whole page makes no network requests. Download the merged MP4 before closing the tab.
