What you see in the editor is a preview of your final video. Before your project can be downloaded, your edits need to be processed to create a downloadable file. Processing begins when you click "Publish" or "CREATE!"

While you wait, you will see the console output scrolling past. This is the actual code that is returned by our cloud servers as they process your video.

Because Kapwing processes videos remotely, in the cloud, it shouldn't heat up your computer or require local CPU. You no longer need a fancy computer to export your videos. This article answer some frequently asked questions about Kapwing video processing.

How long will it take to process my Kapwing video?

Images and GIFs should publish instantly. Videos often take as long to process as the length of the duration. If you see an error message, your video has stopped processing. You'll need to either retry processing or remake your project in order for it to download.

Projects that take longer than 40 minutes to process will timeout.  

Why is it taking so long to process my video?

We're constantly working to improve the efficiency of our video processing technology. Our goal is to make video processing for all Kapwing videos faster than it would have been if you tried to export the same video on a high-end desktop video editor. However, the reality is that processing a video takes time. Each frame of the video must be stitched together into a cohesive MP4, and all of the edits must be applied.

Most short, simple videos should process nearly instantly. Processing time increases if:

  • Your project has many layers or scenes
  • Your project includes large, high resolution, or long video files*
  • Your video is being processed when there are many other users processing their videos at the same time. Processing takes longer during peak hours, especially Monday/Tuesday mornings EST. If your video is taking a long time, try again late in the evening instead.**

*You can process videos faster by avoiding uploads above 1080p. Kapwing's max output resolution is 1080p for videos, and uploads above 1080p will be automatically reduced to 1080p on output.

**Pro users have their own dedicated server for publishing videos, so are less likely to see slow processing for this reason. Find out more about Kapwing Pro.

‘Oh no! An error occurred’. What can I do if I see an error during video processing?

This message appears when your video timed out during processing. This can happen when our servers are busy and could not finish processing your video. You can click “Back” in your browser to return to the editor and try publishing again.

Here are some reasons why a video may fail to publish:

  • Bad files: The most common reasons that a video fails is because an uploaded image or video is corrupted or missing. Check to make sure your image and video files load in the editor, and re-upload files that might be the source of the problem. Try converting your video files to MP4 before uploading them to Kapwing; sometimes the error is related to file conversion.
  • Timeouts: If the video takes more than 40 minutes to process, it will time out. The video may work during a less busy time or if you upgrade to Kapwing Pro.
  • Rogue machines and random failures: For about .1% of all Kapwing videos, our servers just break for no apparent reason, especially for free users and videos shorter than 3 mins. These videos often work if you try to reprocess them.
  • Bugs: Sometimes, when making improvements to our backend, we accidentally make changes that introduce errors. Let us know by filling out our feedback form.
  • Stalled Server: Occasionally, a server will stall and processing with neither timeout or make progress. The progress text will just "freeze" with no indication that an error occurred. In the case that the server has stalled, you will likely need to go back and republish the video.
