In this section, we will go through what HTML video files are and what the ‘HTML5 video file not found’ error means. This overview will also include the reasons behind getting this error message.
What is HTML5 Video File?
HTML5 is the advanced video element necessary to play videos online instead of outdated Adobe Flash plugins. This element is the preferred choice of many web developers for its compatibility with different browsers and sought-after video attributes. When receiving an "HTML5 not found" error, it may mean either the browser does not support the video's format, some codecs are missing, or the website is experiencing issues.
What’s the Cause of HTML5 Video File Not Found?
Understanding the root cause of the "HTML5 video file not found" error is crucial for effective resolution. Let's take a look at the possible causes:
Backend Issues: When there are glitches in the website's code, it can lead to the "HTML5 video file not found" error. This occurs due to backend issues that make the video inaccessible. Web developers can resolve this problem from their end.
Browser compatibility Issues: If a video plays well on one browser but displays the "HTML5 video file not found" error on another, it indicates a browser compatibility issue. This error can also occur if the browser version you're using does not support the HTML5 video codec used on the website. Updating your browser to the latest version can help resolve this problem.
Cookies & Caches: Cookies and caches can sometimes cause issues with video playback on web pages, especially when there are malicious bugs present. Trying to play the video in incognito mode can help determine if cookies and caches are the culprits.
Old Video Compatibility Issues: Older videos on the internet may still rely on flash players, which can cause the "HTML5 video file not found" error when attempting to play them in a browser that only supports HTML5 video files. This happens because these videos lack the necessary HTML5 elements.

Fortunately, an error like "HTML5 video file not found" can be fixed. In this section, we will highlight and elaborate on the different methods by which this issue can be resolved with.
Fix 1: Fix HTML5 Video Not Found by Updating Your Browser
Not all browser versions support the use of HTML5 video files. So, before moving on to other fixes check to see that your current browser version supports HTML5 videos. If it doesn’t, then you may want to update it. You will need to know the current version of your browser to be able to check if it is compatible with HTML5 videos. Follow the steps below to check the current version of your browser. Because Google Chrome is one of the most used browsers on the planet, we will be using it for this illustration.
Step 1: Launch your Chrome browser. Then navigate to the three-dotted icon located at the upper-right corner of your screen and click on it.
Step 2: Click on "Help" and then select "About Google Chrome" from the pop-up menu.
Step 3: If you see the option "Update Google Chrome" then it means your browser is of an older version. Click on it to update to the latest version. The absence of the option means your browser is up to date – if this is the case then you need to move on to the next fix.
Fix 2: Clean your Browser Cookies & Caches to Fix HTML5 Not Found
For a browser to be user-friendly, cookies and caches are essential elements to the progression of this course. They are temporary storage mediums for a small chunk of data. If left unchecked, they tend to accumulate with time causing the browser to perform more slowly than usual. This can lead to difficulties when playing videos online. Clear your cookies and caches and then play the video after refreshing the page. Follow the steps below to clear cookies and caches on your Chrome browser.
Launch Google Chrome, then navigate to and click on the three-dotted icon at the upper-right corner of your screen. From the dropdown menu click on More tools> Clear browsing data.
From the pop-up window, tick both boxes beside “cookies and other site data” and “cached images and files”, select a time range, and then proceed by clicking ‘Clear data’.
Fix 3: Reinstall HTML5 Supporting Codecs to Fix HTML5 Not Found
As earlier mentioned, if your browser does not support the codecs format of the HTML5 video you are trying to access, the video won’t play. In such situations, you can contact the web developer to reinstall HTML5-supporting codecs.
Fix 4: Turn off Hardware Acceleration to Fix HTML Error Loading
Hardware acceleration in chrome aid with accelerating graphics-intensive media such as games, and videos. The hardware acceleration feature transfers the workload from your computer’s CPU to its GPU (Graphics processing unit). Turning off this feature can resolve some processing problems on chrome by placing the burden of loading a page on the CPU. This can potentially solve the "HTML5 video file not found" error. Execute this fix by following the steps below.
- Launch Google Chrome, then navigate to the three-dotted icon located at the upper-right corner of the screen. From the popup menu click on ‘Settings’.
On the Settings window, click the ‘Advanced’ option and then click on ‘System’. On the next window, you will see the ‘Use hardware acceleration…’ option. Turn it off if it’s on.
Fix 5: Start Browser in Safe Mode to Open HTML5 Video
Whenever there’s a browser issue, browsing in "Safe Mode" may be the only solution you need. But with the "HTML5 video file not found" error, it will require much more than that. You see, browsing in Safe mode will help you identify browser issues (Identifying the problem is always the first step to take in solving a problem) to enable you to fix them properly. If the video plays without any form of interruption when using Safe Mode, then it means both your plugins and extension are the culprits or your browser settings. Below are the features of Safe Mode.
- They automatically turn off the hardware acceleration feature.
- Safe Mode restores Chrome’s browser settings to default.
- All add-ons and plugins are disabled.
Fix 6: Download the HTML5 Video to Fix Video File Not Found
If at this point the "HTML5 video file not found" error isn’t fixed, downloading the video from the webpage to your computer may be the best option. Proceed by downloading a reliable HTML5 video downloader to save your desired videos from the internet.
Fix 7: Open HTML5 Video in Incognito Mode to Fix HTML5 Loading Error
Incognito Mode allows a user to browse the internet without the interference of cookies and catches. This fix becomes effective if your cookies and caches are the culprits. On your keyboard, press the Ctrl + Shift + N keys to open Google Chrome in Incognito Mode.
For Mozilla Firefox and Safari browsers, ‘New Private Window’ is referred to as Incognito Mode. If the "HTML5 video file not found" error is fixed after applying this method, the causes of the error message are likely add-ons or plug-ins. Fix this issue in normal mode by removing add-ons and plug-ins, or setting your Google Chrome settings to default.
