Video links

Why an MP4 link will not play, and the fix.

  • The link opens a page, not the file

    A share link from a cloud drive or a file-sharing app opens a download page. You need the link to the file itself, often ending in .mp4.

  • Google Drive links

    A Drive link opens Google's preview, not the file. Download the video and play it with Choose file instead.

  • Dropbox links

    Change the end of the link from dl=0 to raw=1, and it points to the file.

  • The video codec

    MP4 with H.264 video plays in every browser. H.265 (HEVC) plays in some browsers and not in others.

  • The server blocks it

    Some servers do not let other websites play their files. If the link works on its own but not here, that is the cause.

  • A file on your computer

    Press Choose file, or drag the video onto the player. It opens in your browser and is not uploaded.

MP4 player FAQ.

Why is my video not playing?

Check that the link is right and points to an MP4 file. The fixes for the common causes are above: share-page links, codecs and servers that block other sites.

Why is there no sound?

Check that the player and your computer are not muted, and that the file has an audio track.

Why is the video buffering?

Your connection, or the server hosting the file, is too slow for the video. Try again on a faster connection, or download the file and play it with Choose file.

Why is the video quality poor?

The player shows the file as it is. A low-resolution or heavily compressed file looks the same everywhere.

How do I turn on subtitles?

If the video carries subtitles, turn them on in the player's settings.

Is this online MP4 player free?

Yes, free, with no account.

Do I need to install anything?

No. It works in your browser: paste the link and press Play.

Which browsers does it work in?

Current versions of Chrome, Firefox, Safari and Edge.

Can I play an MP4 file from my computer?

Yes. Press Choose file next to Play, or drag the video onto the player. It opens in your browser and is never uploaded to our servers.

Is there a limit on file size or length?

The player sets none. A very large file takes longer to start, depending on your connection and the server that hosts it.

Are the videos I play stored anywhere?

No. The player loads the video straight from the link you give it, and we keep nothing.

How do I embed this player on my website?

Embedding is a paid feature, $20 a month: write to [email protected] to turn it on. Then press Embed player next to Play, set the size, and copy the iframe code into your page.

How do I play a video in the browser if I only have a link?

Copy the direct link to the MP4 file, paste it in the field above and press Play. Nothing to download or install.

How do I play a Flezen or other file-sharing link?

These links open a download page, not the file. Get the direct link to the file, often ending in .mp4, or download the video and play it with Choose file.

Can I open the player with a video already loaded?

Yes. Add the link to the page address: livereacting.com/tools/mp4-player?url=YOUR_VIDEO_URL. The page opens with the video ready to play, which is handy for sending someone a link to test.
