I was able to create a workaround using the parameters of substr, by clarifying the the point after the video URL and headline, and before the next section’s text.:

$content = strip_shortcodes(get_the_content());
$content = strip_tags($content);

$subdotcom = strpos($content, '.com');
$suburl = ($subdotcom + 13);
$substart = strpos($content, '.', $suburl) + 1;
$subend = strpos($content, 'SYNOPSIS');
$sublength = ($subend - $substart);

echo substr( $content, $substart, $sublength );
