## Video formats

| Format | What happens when you open it |
| --- | --- |
| MP4, MOV, M4V, WebM, MKV, OGG and OGV, 3GP | Plays right away in the Drime player, as long as your browser can decode the video's codec. |
| AVI, WMV, TS, M2TS, MTS, VOB and other video formats | Drime plays an MP4 copy made for the web: one prepared after the upload, or one converted in your browser when you open the video, with its progress shown. |
| A video whose codec your browser cannot decode | Drime shows **This video uses a codec your browser can't decode (…).** or **This video can't be played in the browser.** with **Download**, and **Convert in this browser** when the conversion can run in your browser. |

**Convert in this browser** is not offered for very large files, nor on a share link page. **Converting happens on your device and can take a few minutes.** Otherwise, download the video and play it in a desktop player such as VLC.

**Symptoms**

- The video does not start, or the player shows that the format cannot be played.

**How to fix it**

### Convert it in your browser

When your browser cannot play the video's format, Drime offers **Convert in this browser**. Click it: the conversion runs in your browser.

### Download it

If the conversion does not help, download the video and play it with a player on your computer. See [Download files and folders](https://drime.cloud/support/drive/download-files-and-folders).

### Try another browser

Browsers do not all support the same video formats. Open Drime in another recent browser and try again.

**Still stuck?**

If a common format such as MP4 does not play, [contact support](https://drime.cloud/support/getting-started/contact-drime-support) with the file's format, its size and the browser you use.
