WEBM Videos are Not Playing! Are they corrupt?

If the videos are not playing in your media player or browser, it is not always due to corruption. Sometimes, the support system required to play WEBM files is not in place. It could be anything from the outdated browser, computer, or absence of the required codec pack.

Dos’ when WEBM video files are not playing in browser or media player

  1. Get the compatible codec

If your chosen media player lacks the supporting codec, it will not play the WEBM files. Ensure that you have the compatible codec in your system or playing the files in a media player that supports WEBM files.

  1. Download videos again from source

Sudden power cut, loss of internet connection, or server issues can make the videos sluggish or turn them non-playable. Simply wait for some time for the server or the Internet connection to be up, and then try downloading the videos again. If the video file was copied or transferred from any drive/ storage card, do it again.

  1. Update the web browser

‘I’m building a website with full-page videos and converting my MOV videos to WEBM (vP8) for Chrome and Firefox. For some unknown reason, I can’t play the WEBM video file in Firefox though it loads just fine in Chrome.’

If you are facing such issues, remember, outdated web browsers also hampers the videos from playing or loading properly. Whether you are using Chrome, Mozilla Firefox, Opera, or Internet Explorer, ensure that it is updated to fully support WEBM videos. Also, make sure Adobe Flash is enabled on your browser.

  1. Delete the cache and temporary files

Often, the video problems like playing very slow or taking longer buffering time get fixed by removing cache and temporary files on the system. This helps your browser and computer to work better and load videos faster.


Video repair software like Stellar Repair for Video provides an effective solution to fix corrupt WEBM videos. However, if the damage is minor, you may also try out a video editing software and plugins to do the task. The applications reduce noise and manage to give acceptable results.

In case you are not proficient in using video editing software or find the plugins an expensive pick, a video repair application is better in terms of convenience and overall value. They are fast, easy-to-use, offer better repair results in terms of fixing even severely corrupt videos.
