How to Combine YouTube Clips
Published August 18, 2026
This walks through pulling audio from several separate YouTube videos into a single MP3, using TubeMixLab's merge tool — adding each source, trimming it, arranging the order, and exporting one track.
1. Open the merge tool
Go to Merge YouTube Audio. It's the same clip-based tool as the mixer, set up specifically for the "combine several separate videos" workflow. It opens with one empty source row ready for your first link.
2. Add each source video
Paste the first YouTube URL into the source row — TubeMixLab fills in its title, channel and thumbnail once it resolves. Click "Add another source" to add a row for your next video, paste its link, and repeat for every video you want combined.
3. Trim each source
Every source gets its own waveform with independent In and Out handles. Drag them to the part of that video you want included, or type exact timestamps into the In/Out fields — the rest of that source is left out of the merged file.
4. Arrange the order
Drag a source by the grip handle at the left of its header to move it earlier or later. The export preview below the source list updates as you reorder, so you can check the running order before merging.
5. Merge and export
When your sources are trimmed and in the order you want, click "Merge & Export". TubeMixLab downloads each source, cuts the section you chose from it, and stitches them together into a single MP3 in that order — with a progress bar while it renders, then a play button and Download link once it's ready.
Tips
- Add a short fade-in or fade-out to a source if you want a smoother transition into or out of it, instead of a hard cut.
- Sources don't need to be trimmed — leave a source's In and Out handles at the full length to include the whole video in the merge.
- Only combining one section from one video? Use the YouTube Audio Cutter instead — this guide is specifically about combining more than one source.
Frequently Asked Questions
Can I combine clips from completely unrelated videos?
Yes — each source is added and processed independently, so they can be any combination of videos.
Does the order I add sources in matter?
No — you can add them in any order and then drag them into the order you actually want them to play using the grip handle.
Is there a limit to how many videos I can combine?
You can add multiple sources to a single merge; TubeMixLab enforces a maximum per export to keep renders reliable.
What's the difference between this and the mixer?
They're the same tool. This page and guide are focused specifically on the "combine several full videos" case; the YouTube MP3 Mixer is the general entry point that also covers trimming a single clip.
