Put every speaker in one branded video, right in the browser
Drop one video per speaker, pick 16:9, 9:16 or 1:1, a background colour and your logo if you like. Every track gets its own slot; cut on the timeline and render one MP4. Nothing is uploaded.
Your file never leaves this browser tab. Nothing is uploaded.
Drop your video tracks here
MP4, MOV or WebM, one file per speaker. Up to 6 tracks.
This browser cannot edit video. Use a current Chrome, Edge, Firefox or Safari on a computer.
One frame, every speaker
A remote podcast or interview ends with one video file per person. To publish it, you need them together: side by side for YouTube, stacked for Reels, in your colours instead of a meeting window. This editor builds that frame. The number of slots follows the number of tracks, and the grid or speaker layout keeps every face clear of your logo.
The preview plays all tracks in sync, and the timeline is the same one the audio editor uses: trim, shift and cut clips, mute or lower a track. When it looks right, your browser renders the finished MP4 with your graphics card.
How to use it
#howAdd one video per speaker
Drop up to 6 files: MP4, MOV or WebM. A track with sound only becomes a named slot, so a guest without a camera still appears.
Choose the look
Pick the format, a grid or speaker layout and the background colour. Add a logo if you want one and place it in a corner; without a logo the slots use the whole frame. Your choices are kept for next time.
Cut and render
Trim, shift and split clips on the timeline, set each track's volume, then render. The result is an MP4 (H.264 and AAC) at 1080p and 30 frames per second.
What you can set
#features| Setting | Options | What it does |
|---|---|---|
| Format | 16:9, 9:16, 1:1 | Sets the frame for YouTube, Reels, Shorts, TikTok or social feeds. |
| Layout | Grid, speaker | Grid gives everyone the same size; speaker shows the first track large and the others beside or below it. |
| Background | Swatches or any colour | Fills the frame around the slots in your brand colour. |
| Logo | Optional, four corners | Keeps a strip free on its side so it never covers a face. |
| Timeline | Per clip and track | Trim, shift, split and delete clips; volume and mute per track. |
Tips for a clean video
#tips- Record every speaker on a separate track, as Airtape does, so each person gets a clean slot instead of a cropped meeting window.
- Use the speaker layout for an interview with a host, and the grid for a panel.
- For 9:16 clips, put the logo at the bottom so the top stays free for captions you add later.
- Render on a computer: a 40-minute episode takes a few minutes there, a phone needs much longer.
What happens to your files
#privacyYour videos are read and rendered by your browser. The picture is decoded and encoded with the WebCodecs API and your graphics card, the sound is mixed with ffmpeg compiled to WebAssembly. Nothing is sent to Airtape or any other server, and the finished file stays in your browser's private storage until you download it.
Only your look settings, including a small logo, are kept on this device for your next visit. The videos are not stored, so keep the tab open until you have downloaded the MP4.

Frequently asked questions
No. Preview and rendering both run in your browser tab, and the MP4 is created on your device.
No, the logo is optional. Without one the slots use the whole frame; add one later and the layout makes room for it.
On a current laptop, a 40-minute episode with three 1080p tracks renders in about five to seven minutes. It depends on your computer, not on your internet connection.
Current Chrome, Edge, Firefox and Safari on a computer. The browser needs WebCodecs with an H.264 encoder; if that is missing, the editor tells you before you start.
The audio editor exports sound only. The video editor uses the same timeline but puts each track's picture into a branded frame and renders an MP4 with picture and sound.
