About this tool

Combine multiple separate video files into one continuous video, in the order you choose - useful for stitching together clips from a multi-part recording, combining footage from different cameras/takes, or assembling a compilation from several source files.

How to use this tool

  1. Upload all clipsAdd source videos that should appear in final sequence.
  2. Arrange clip orderReorder segments to match narrative or timeline flow.
  3. Run merge processCombine clips into one continuous output file.
  4. Review merged videoCheck transitions, sync, and formatting before delivery.

Merging clips without jumps or black frames

Clips join most cleanly when they share the same resolution, frame rate and orientation, so record or export them with the same settings. Mixing portrait and landscape clips usually adds black bars to some of them.

Put the clips in order before merging, and trim each one first so the joins land where you want them.

Key features

  • Combines separate takes into one shareable file.
  • Simplifies multi-part publishing workflows.
  • Useful for compilations, tutorials, and event recaps.
  • No advanced timeline editing required.

Common uses

  • Stitching phone clips into one highlight reel.
  • Joining lecture parts for single upload.
  • Combining multi-camera segments sequentially.
  • Merging serialized clips for client delivery.

Tips for better results

  • Normalize resolutions/frame rates before merge for consistency.
  • Place title/intro clip first to improve context.
  • Check audio continuity between adjacent clips.
  • Trim noisy starts/ends before merging.

Mistakes to avoid

  • Merging incompatible codecs without re-encoding plan.
  • Incorrect clip ordering causing narrative confusion.
  • Ignoring abrupt audio level jumps between segments.
  • Assuming merge can fix shaky/poor-quality source footage.

Frequently asked questions

Yes - clips are combined in the order you add them; reorder them before merging if you picked them in the wrong sequence.

Merging works best when source videos share similar resolution and format - mixing very different resolutions or formats can sometimes produce inconsistent results depending on how the merge handles the mismatch.

Merging aims to preserve each clip's original quality as much as possible, though some re-encoding may occur to combine clips into a single consistent output file.

Merge clips that share the same resolution, frame rate and orientation where possible, and trim any dead air at the start and end of each clip before joining them.

Travel and event recaps, multi-part lecture or webinar recordings, tutorial series joined into one file, and compilations of short phone clips for sharing with family.

Its size is roughly the sum of the clips. If it is too big to send, trim unneeded parts first or run the result through a video compressor.
