I have posts that have video content and these videos stored in database like this (serialized) a:1:{s:9:video_url;s:0:;}
This serialized data have post video urls but can not get this data. I used ?php echo get_post_meta(get_the_ID(), '_custom_field', TRUE); ?
But this get_post_meta display output array instead of video urls

get_post_meta() with the 3rd parameter set to true will return a single item with the key specified in the 2nd parameter (_custom_field in your code). If this item is an array, it'll return as the array. In your case, it appears that the data is:
array(
'video_url' => '',
)
...which is why, when you try to echo it, it's printing Array to the screen.
I'd suggest something more like this:
<?php
$meta = get_post_meta(get_the_ID(), '_custom_field', TRUE);
echo $meta['video_url'];
?>
...or, if you're expecting multiple video_urls, you could do this:
<?php
$meta = get_post_meta(get_the_ID(), '_custom_field');
foreach ( $meta as $item ) {
echo $item['video_url'];
}
?>
(Note that it also appears that, in the metadata you've posted, there's an empty value for the actual video_url, but I can't say what might have caused that.)
