Hi Jérôme,
This is possible but you will have to override the default theme file that displays the video items on the blog page.
To do this, please install and activate the child theme. If you do not have the child theme installed yet, you can download it from here. Once you have it installed and activated, please login through FTP then go to wp-content/themes/x-child then go to the following file path framework/views/integrity if any directory is not present yet, you may create the folder until you get to the integrity directory.
Once you’re in the integrity directory, create the file content-video.php then add this code to the file:
<?php
// =============================================================================
// VIEWS/INTEGRITY/CONTENT-VIDEO.PHP
// -----------------------------------------------------------------------------
// Video post output for Integrity.
// =============================================================================
?>
<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<div class="entry-featured">
<?php x_featured_image(); ?>
</div>
<div class="entry-wrap">
<?php x_get_view( 'integrity', '_content', 'post-header' ); ?>
<?php x_get_view( 'global', '_content' ); ?>
</div>
<?php x_get_view( 'integrity', '_content', 'post-footer' ); ?>
</article>
Kindly note that since this is a custom code that changes the default behavior/display of the theme, you will be responsible to maintain or update the code in case you require further changes or if the code stops working in future updates. If you are uncertain how to proceed, it would be best to get in touch with a developer.
Hope this helps.
