Are you outputting all of the sub fields in the same loop?
<?php
// check if the repeater field has rows of data
if( have_rows('video_tutorial') ):
// loop through the rows of data
while ( have_rows('video_tutorial') ) : the_row();
// display a sub field value
the_sub_field('title');
echo '<br>';
the_sub_field('outline');
echo '<br>';
the_sub_field('embed');
// etc...
endwhile;
else :
// no rows found
endif;
?>
