i need a wix coding website

We need ADVANCED TECHNICAL CODING to meet the following requirements: (Wix support says these features require CUSTOM CODING, however if the site will start to “error” as a result of custom code, a better solution for us is to recreate this site in Wordpress, where these features are already available *can you please let me know if the site functioning could “error” as a result of these requests. Site details: [login to view URL] WIX Template Used: Indie Production Company DETAIL: This site has bi-weekly Poem (Video) releases (x1 video two times a week). The primary requests: 1) refer pg: Archieve 1. Code for this: To be able to preload in advance single pages (this is the POP-UP window page that appears when video is selected, ONE large video at top, but without the video slider at the bottom, just one large video at the bottom) - AND To send each video automatically to Archieve 1 Template page at a selected Time and Date (12.01am New York Meantime every Monday and Friday) - this backend archive acts as the building block for the whole site. (Note: This must be a user friendly template on the back end so the Client can easily set up. A MailChimp biweekly e-mail will be pre-scheduled WITH the link to this page (note: this link direct to the is the POP-UP video page of the latest release, not the full archive list page), to inform subscribers of release - time based. 2) HOME PAGE: Latest Released Video that AUTOMATICALLY loads and changes to the latest released video (x2 per week) as the Latest Video is released. Landing (HOME) Page to house Featured Video which is the latest Released Video and automatically change out as video’s are released x2 per week. Landing Page to house Featured Video which is the latest Released Video and automatically changes out as video’s are released x2 per week. - FULL SCREEN Video Slider (this sits in background under the Main Menu with current subtle black band transparency, note: this does not actually slide from image to video across page but slow fades in and out as it transitions) - Start with full still Image of Constance (half head) with wording “The Voice of Poetry” “Bi-weekly Poetry Readings” (always stays) - Slow dark fade into Video of the Featured Poem (this automatically loads from the latest release from Archive Page) *This automatically plays (with sound) & can be paused at any stage.
