Video-Survey: we need a little demonstrator

We need a demonstrator to show how a video-survey could work, i.e. people are answering a survey not by multiple-choice, but with a real recording of themselves. Short: A person (click on a deeplink) shall answer 3-5 questions of a survey via video-recording. No App, but responsive website for desktop and - especially - mobiles. Detailed: Three to five questions are defined by an multidimensional array of strings (the question) plus numbers (max. seconds for recording). This is provided in a configfile (or database). After a user clicks the deeplink and sees the landingpage … Two solutions: 1.) One recording for each question User sees first question (configfile) and he starts recording by himself. Recording will stop at the given amount of seconds (configfile). The second question will then be shown and the user starts the recording again by himself … and so on. 2.) Single recording for all questions The user is shown all questions upfront and he starts the recording hitting a button. Now he is presented the first question (while recording) and after given seconds for that question (configfile) the next question is shown (recording keeps running) and so on. For all solutions: After this the user shall enter his name, email, and phonenumber. All saved to the database, of course. Video(s) may be saved as file(s). The layout shall be nice and have a serious touch. Showing a company/survey-logo would be nice. A footerline is necessary (at least at the beginning or end) for links to privacy and imprint-information (these pages do not have to be provided). P.S.: PHP: 8.1.9 Database: MariaDB UI-Framework: Would be nice, like react. Template-Engine: „Smarty“ would be great, but does not have to be used.
