How to Fix Clipchamp Captions Transcribing the Wrong Audio Track
Question details
The user is experiencing an issue where Clipchamp auto-captions generate text based on the wrong audio track.
- Product
- Microsoft Clipchamp
- Device & OS
- not provided
- Scenario
- Generating auto-captions for a multi-track or complex video project in Clipchamp.
- Observed behavior
- Auto-captions transcribe the wrong audio source, and the issue persists even after disabling captions or testing different videos.
Before making changes, verify that your browser or Clipchamp desktop app is updated to the latest version and ensure your internet connection is stable, as auto-captions rely on cloud processing.
Re-import Media and Convert File Formats
Removing the media from your bin and changing the file format often forces the Clipchamp engine to process the correct audio track.
In some cases, specific file containers like M4A or WebM can confuse the transcription engine, causing it to read the wrong audio stream. Converting to universally supported formats can resolve this.
Hover over the affected media in the Clipchamp media bin and click the trash can icon to remove it from your project.
If the file is in WebM or M4A format, use a local or online file converter to change the video to MP4 or the audio to MP3.
Click 'Import media' to add the newly converted file back into Clipchamp, drag it to your timeline, and turn on the auto-captions feature again.
Export the Video Without Captions and Re-caption
Exporting flattens all audio tracks into a single output, ensuring the captioning engine only hears the final mixed audio.
Need a Reliable Office Suite for Your Video Scripts?

Frequently Asked Questions
Why does Clipchamp generate captions from the wrong audio track?
This typically happens in multi-track projects where the auto-captioning engine misidentifies the primary voice track, or if specific audio containers (like M4A or WebM) cause metadata reading errors during cloud transcription.
What audio and video formats work best for Clipchamp captions?
Standard formats like MP4 for video and MP3 or WAV for audio are highly recommended, as they have the highest compatibility and reliability with Clipchamp's transcription engine.
Can I manually edit the auto-captions if they are slightly incorrect?
Yes. Once the captions are generated, you can click on the text in the Captions tab on the right-hand property panel to manually correct any spelling, timing, or wording errors.
