# Some visitors cannot view a Video on my site

Making videos available to as many devices and browsers as possible take a bit of careful work.

A video file that you have on your system might be playable for you, but not be playable on somebody else's computer or browser. So it is important to save your video in a format that is visible for as many people as possible.

Though Sandvox support many video formats, you may want to consider exporting your video to a more universal format.

The ideal format is MP4 format, with the H.264 codec, with some particular options that will make the video compatible with iPhone and iPad. If you can export your movie into this format, then your movie will be visible to the most viewers, running Macs, PCs, or iOS devices, and various browsers such as Internet Explorer, Firefox, Safari, and Chrome.

How to convert your video to this format:

- It is possible that the software used to produce the video can convert the video to a more suitable codec. Please see your software's manual for more information.
- If your movie is managed by iTunes, you can select the video and choose "Create iPad or Apple TV Version" (or "Create iPhone version" for smaller-sized movies) from the Advanced menu.
- Using Apple's QuickTime Player application, you can choose "Export for Web…" to produce a suitable file. Exporting this will result in a folder with several variations of the file; select the resulting ".m4v" file that matches the size of the movie you wish to put on the website.
- Some other utilities that may be of use: Handbrake, SimpleMovieX, Miro Video Converter, and Apple's Compressor.

### Server Issues

We have encountered an issue where some web hosts do not properly tag video content, which causes some browsers (notably Internet Explorer) to not play videos. if your movies play OK on Mac, iPhone, etc. but do not play on IE, you may want to contact your hosting company (or dig in with your browser's web inspector if you are comfortable doing so) to check the headers that your web host sends along with any video content that is fetched from your website.

You can use a tool like http://web-sniffer.net to look at the headers of the actual video file on your website. If you see a line like Content-Type: text/plain then you know that there is a problem with your host.
