Answer 1

These two functions here will grab data from the YouTube API about a video:

    // function to parse the code from the URL
    function parse_youtube_video_id_from_url( $video_url ) {
        $splited_data = explode( '=', $video_url );
        $video_unique_code = substr( $splited_data[1], 0, -strlen( strrchr( $splited_data[1], '&' ) ) );
        return $video_unique_code;
    }

    // use the youtube APIs to get a json string containing data about the video
    function get_youtube_json_video_data( $video_code ) {
        $api_url = "https://gdata.youtube.com/feeds/api/videos?v=2&alt=jsonc&q={$video_code}";
        $data = wp_remote_get( $api_url );
        return wp_remote_retrieve_body( $data );
    }

You must use these to get the time data

So for your example, here's how you'd get the data:

$youtubecode = 'QiNIfGiNiOk'; // replace with your youtube code or variable etc etc..
$video_data = get_youtube_json_video_data($youtubecode);
$video_data = json_decode( $video_data );

Then finally, to see what data you got, let's pass the video_data into print_r to put some debug output on the screen:

// lets print out the data so we can see what we got:
printf( '<pre>%s</pre>', var_export( $video_data, true ) );

You should see a pre tag containing a PHP data structure with everything you could ever want to know about the YouTube video (assuming the video exists).

And there you go, $video_data should contain the time, description, uploader, all the thumbnails, ratings, etc

You would then use this new found knowledge to create a function, hook that function into the 'save_post' and 'publish_post' actions, that updates the post meta/custom field based on the above code

How to use filters and actions, or how to grab from or save to a custom field, is beyond the scope of your question.
