I fixed it by doing the following:
1- In my WordPress theme folder /wp-content/themes/my-theme/
I created an Custom Page Template reference to this guide: Custom Page Templates
Using this code:
<?php
/**
* Template Name: Video Template
* Description: A Page Template for Home page Video CMS.
*/
defined('ABSPATH') or die;
use Timber\Timber;
$gantry = Gantry\Framework\Gantry::instance();
$theme = $gantry['theme'];
// We need to render contents of <head> before plugin content gets added.
$context = Timber::get_context();
$context['page_head'] = $theme->render('partials/page_head.html.twig', $context);
$post = Timber::query_post();
$context['post'] = $post;
Timber::render(['page-' . $post->post_name . '.html.twig', 'page-hvideo.twig'], $context);
Where Timber::render(['page-' . $post->post_name . '.html.twig', 'page-hvideo.twig'], $context);
pointing us to the new Timber page-hvideo.twig
file under theme/view folder.
2- And in my Timber template view folder I added this file page-hvideo.twig
with the following code:
{% extends "partials/page.html.twig" %}
{% set twigTemplate = 'single.html.twig' %}
{% set scope = 'single' %}
{% block content %}
<div class="platform-content">
<div class="content-wrapper">
<section class="entry">
{% include ['partials/content-' ~ scope ~ '-home-video.html.twig', 'partials/content-home-video.html.twig'] %}
</section>
</div> <!-- /content-wrapper -->
</div>
{% endblock %}
Where {% include ['partials/content-' ~ scope ~ '-home-video.html.twig', 'partials/content-home-video.html.twig'] %}
Will manage the home page custom template from view/partials folder under Timber theme folder as normal.
I hope this will help anyone else.
Thank you so much for everything you provided here.
EDITED:
Please be sure after you add your Home Page custom page template to select it from your post editing screen in WordPress under Page Attributes section.
