# Troubleshooting

> Solutions for common issues in Cardboard.

Running into a problem? Check the common issues below for a quick fix. If your issue isn't listed, reach out to the team and we will help you out.

## Export issues

<AccordionGroup>
  <Accordion title="My export seems stuck">
    Exports run entirely in your browser, so large projects with many clips or high resolutions take longer to render. Check the progress bar — if it is still moving, the export is working. If it has stalled for several minutes:

    * Try reducing the resolution (e.g., switch from 4K to 1080p)
    * Close other browser tabs to free up memory
    * Try exporting in a different format
  </Accordion>

  <Accordion title="Export failed with an error">
    * Try a different format (e.g., switch from WebM to MP4)
    * Reduce the quality level
    * Make sure you are using a supported browser — **Chrome** or **Edge** are recommended for best performance
    * If the issue persists, try reloading the editor and exporting again
  </Accordion>

  <Accordion title="Exported video has no audio">
    * Check that the audio track is not muted on the timeline
    * Check the clip volume — make sure it is not set to 0%
    * Ensure the audio codec is supported by your playback device
    * Try exporting as MP4, which has the widest audio codec support
  </Accordion>
</AccordionGroup>

## Media issues

<AccordionGroup>
  <Accordion title="My video won't import">
    * Check that the file format is supported (MP4, WebM, MOV, MKV, MP3, WAV, AAC, PNG, JPG, GIF, WebP)
    * Try re-encoding the file with a tool like [HandBrake](https://handbrake.fr) or FFmpeg
    * Make sure the file is not corrupted — try playing it in another application first
    * Check that the file does not exceed your plan's maximum file size
  </Accordion>

  <Accordion title="Transcription isn't working">
    * Make sure the video has audible speech — very quiet or heavily distorted audio may not transcribe well
    * Check that the audio track is not muted
    * Try re-importing the file to trigger a fresh transcription
  </Accordion>

  <Accordion title="Video analysis is taking a long time">
    Video analysis runs in the cloud, so processing time depends on file size and current server load. Larger files naturally take more time. Check your network connection and wait a few minutes — the analysis will complete in the background while you edit.
  </Accordion>
</AccordionGroup>

## Editor issues

<AccordionGroup>
  <Accordion title="The editor is slow or laggy">
    * Close unused browser tabs to free up memory and CPU
    * Reduce the preview resolution in the canvas settings
    * Use **Chrome** or **Edge** for the best performance — these browsers have the strongest support for video processing
    * If you have many clips on the timeline, try breaking your project into shorter sections
  </Accordion>

  <Accordion title="I can't hear audio in the editor">
    * Check the **master volume** slider in the timeline toolbar
    * Make sure the audio track is not muted (look for the mute icon on the track)
    * Check your system audio settings and make sure your output device is correct
    * Try clicking somewhere in the editor first — some browsers require a user interaction before playing audio
  </Accordion>

  <Accordion title="My changes disappeared">
    * Try **Cmd+Z** (or **Ctrl+Z**) to undo — you may have accidentally deleted or moved something
    * Projects auto-save locally, so your work should be preserved. Make sure you have the correct project open
    * If you are signed in, check that your browser did not clear local storage or cookies
  </Accordion>
</AccordionGroup>

## AI issues

<AccordionGroup>
  <Accordion title="The AI isn't doing what I asked">
    * Be specific in your prompts — "Trim the first 5 seconds" works better than "make it shorter"
    * Break complex requests into smaller steps instead of one large prompt
    * Check [How to Talk to Cardboard](/learn/talk) for tips on writing effective prompts
    * If the AI misunderstood, type "Undo that" and try rephrasing your request
  </Accordion>
