I need a file code so that videos can be uploaded to the form from a mobile phone

You can use the File Upload tool to allow your users to upload their video files. Please refer to this user guide: How-to-Create-File-Upload-Forms

We also have widgets available, please check this link: https://widgets.jotform.com/category/video. Here's a guide on How-to-Add-a-Widget-to-Your-Form.
