Frequently asked questions

What is the Stitch & Trim Editor?

A browser tool that lets you import multiple video clips, trim the start and end of each one, reorder them, and export the result as a single MP4. Think of it as a fast lane for joining together a handful of takes without launching a full editor like Premiere or Final Cut.

Why do I need a Stitch & Trim Editor?

Most social videos are 2 to 5 clips joined together. Loading up a full editor for that is overkill. Stitch & Trim is built for the common case: you have a few takes, you want to cut the dead air at the start and end, glue them together, and post. Great for B-roll compilations, recorded interviews, multi-camera takes, and quick demo edits.

Is it free to use Stitch & Trim?

Yes, 100% free. The Stitch & Trim Editor is part of the Jupitrr Free Video Toolkit. We want to build quick and easy video tools that help you every step in creating content for your business.

Do I need to download or install anything?

No. The Stitch & Trim Editor runs entirely in your browser, so there is nothing to download, install, or sign up for. It works on macOS, Windows, ChromeOS, and Linux as long as you can open the page. No desktop app, no extension, no plugin.

What video formats can I import?

Most modern formats: MP4 (H.264, H.265), MOV, WebM, and MKV. If your browser can play the file, the tool can import it. If a clip fails to load, re-encode it as MP4 (H.264) first and try again.

Can I reorder clips after I add them?

Yes. Drag the clips on the timeline to change the order. Each clip also has in and out handles you can drag to trim the start and end without re-importing the file.

Will it re-encode my video?

Yes. When you export, the tool stitches the trimmed clips into a single MP4 file. Re-encoding is what lets the output play smoothly across players, but it does take a few seconds per minute of video, so longer projects take longer to finish.

Is there a watermark or time limit?

No watermark, no signup, no time limit. The only practical limit is your machine: very long projects (over 30 minutes of stitched footage) can use a lot of browser memory.

Does this replace a full video editor?

No, this is built for fast cuts and joins. When you need subtitles, B-roll, filler-word removal, animated text, or one-click publishing, open the full Jupitrr AI Video Editor.

What video file, resolution, and quality do I get?

You get an MP4 file in Full HD (1080p, 16:9) at 30 frames per second. The quality is high enough for YouTube, LinkedIn, and most client work, while still being small enough to download in seconds. MP4 plays everywhere and imports cleanly into Jupitrr or any other video editor.
