Modify Video Script (joomla)

I will provide the script, which is by "joomla". It is a video script that I want to modify: This is a link to show how the script look like: [login to view URL] These are the options that I want to add to the script: 1. Option for users to download videos from the frontend 1. The website should have two types of users: i. Guest and free users ii. Paid users 2. Guest or free users can only view the videos from the frontend and they cannot download videos. Their viewing capacity to the videos will also be restricted. The admin has a feature of posting a few video in full length where any "user" (paid of free user) can view the videos for free without making any payment or registration with the website. 3. This can be implemented through the following steps: i. Every video displayed on the frontend of the website will have a thumbnail image for it ii. Since all the videos are to be custom uploaded either by the admin or by the user, the thumbnail image has to be set by them for those videos to be displayed on the frontend (if there is no picture for the video, the admin can add one from his area) iii. Below the thumbnail image of these videos we will display two buttons "Preview" and "Full video" iv. Any user who visits the website can click either of these buttons to view the videos (any free video should be specified as "FREE FULL VIDEO". v. If the user clicks on "Preview" then the video will get automatically played on the player and this video size will be restricted to just 1minute time vi. If the user clicks on "Full video" (not "Free Full Video) then a pop-up message will open up asking for the user to login using his login credentials(if he has already registered with the website) and the same pop-up will also have the link for sign-up/Register in it vii. If the user has not registered with the website so far then he/she can click on the signup/register link, then they will be redirected to the corresponding form to enter their name, email etc.. and submit for registration viii. As soon as the registration details are submitted in that form the user will be redirected to a new page to subscribe for the plan he wants to view and download the videos on the website ix. The page will have a drop-down menu displaying the various monthly plans set by the admin for subscription and depending upon the plan selected by the user, the cost will be calculated x. After choosing the corresponding plan the user can proceed to the checkout page to process the payment and thus he will create his own login and subscription on the website Automatically. xi. The subscribed user can thus now view all the videos in full length and also download them from the website Whereas the free or guest users can just view the preview videos and the "free full video" on the website and cannot download them More to the project on the Attached file.
