I have just uploaded my holiday pictures and videos to ipad and can't view the videos, I get sound and no picture. Can anybody help?

Hi Andy,

Welcome to Apple Support Communities.

How were the videos created? If the videos are in a format that isn't listed below, they may need to be transcoded or exported the from the application they were created with again, just in a another format.

You can find more information about the supported video formats here:
