Well that colon is 100% a colon or a { depending on your syntax.

the endwhile error most likely refers to you missing an end tag somewhere… Can you provide your template file and functions file?

@wpdragon, what is or isn’t happening? are you able to get the URL to show at all?

Is you oEmbed field within the repeater? or a field of its own?

Are you getting any errors?

@WPDragon i should have mentioned i just made up the markup without testing or looking at lightbox documentation — also if your using a repeater try this for testing:

					
<?php //For Use with Repeater Field 
$videos = get_field('video');
$videos_raw = get_field('video', FALSE, FALSE);
									
								
//Add the Thubmnail to the $videos object
									
									foreach($videos_raw as $key => $video_raw) : 
								
											$videos[$key]['video_thumb'] = get_video_thumbnail_uri($video_raw['field_5449746362c3d']); 
//Replace 'field_5449746362c3d' with your field's Field key (obtainable by going to screen options in the fields admin, and setting 'Show Field Key' to 'Yes')
								
endforeach;
									
								
								
//Loop through the $videos object
									foreach($videos as $video): ?>
									
VIDEO THUMB URL: <?php echo $video['video_thumb']; ?>
										
							
										
										VIDEO EMBED: <?php echo $video['video_url'] ?>
																		
<? endforeach; ?>

My solution is a bit more comprehensive than that of @scheurta, as it covers multiple video sources. Youtube, Vimeo, and Wistia.

First off in functions.php:

	function get_video_thumbnail_uri( $video_uri ) {
	
		$thumbnail_uri = '';
		
	
		
		// determine the type of video and the video id
		$video = parse_video_uri( $video_uri );
		
		
		
		// get youtube thumbnail
		if ( $video['type'] == 'youtube' )
			$thumbnail_uri = 'http://img.youtube.com/vi/' . $video['id'] . '/hqdefault.jpg';
		
		// get vimeo thumbnail
		if( $video['type'] == 'vimeo' )
			$thumbnail_uri = get_vimeo_thumbnail_uri( $video['id'] );
		// get wistia thumbnail
		if( $video['type'] == 'wistia' )
			$thumbnail_uri = get_wistia_thumbnail_uri( $video_uri );
		// get default/placeholder thumbnail
		if( empty( $thumbnail_uri ) || is_wp_error( $thumbnail_uri ) )
			$thumbnail_uri = ''; 
		
		//return thumbnail uri
		return $thumbnail_uri;
		
	}
	
	
	/**
	 * Parse the video uri/url to determine the video type/source and the video id
	 */
	function parse_video_uri( $url ) {
		
		// Parse the url 
		$parse = parse_url( $url );
		
		// Set blank variables
		$video_type = '';
		$video_id = '';
		
		// Url is http://youtu.be/xxxx
		if ( $parse['host'] == 'youtu.be' ) {
		
			$video_type = 'youtube';
			
			$video_id = ltrim( $parse['path'],'/' );	
			
		}
		
		// Url is http://www.youtube.com/watch?v=xxxx 
		// or http://www.youtube.com/watch?feature=player_embedded&v=xxx
		// or http://www.youtube.com/embed/xxxx
		if ( ( $parse['host'] == 'youtube.com' ) || ( $parse['host'] == 'www.youtube.com' ) ) {
		
			$video_type = 'youtube';
			
			parse_str( $parse['query'] );
			
			$video_id = $v;	
			
			if ( !empty( $feature ) )
				$video_id = end( explode( 'v=', $parse['query'] ) );
				
			if ( strpos( $parse['path'], 'embed' ) == 1 )
				$video_id = end( explode( '/', $parse['path'] ) );
			
		}
		
		// Url is http://www.vimeo.com
		if ( ( $parse['host'] == 'vimeo.com' ) || ( $parse['host'] == 'www.vimeo.com' ) ) {
		
			$video_type = 'vimeo';
			
			$video_id = ltrim( $parse['path'],'/' );	
						
		}
		$host_names = explode(".", $parse['host'] );
		$rebuild = ( ! empty( $host_names[1] ) ? $host_names[1] : '') . '.' . ( ! empty($host_names[2] ) ? $host_names[2] : '');
		// Url is an oembed url wistia.com
		if ( ( $rebuild == 'wistia.com' ) || ( $rebuild == 'wi.st.com' ) ) {
		
			$video_type = 'wistia';
				
			if ( strpos( $parse['path'], 'medias' ) == 1 )
					$video_id = end( explode( '/', $parse['path'] ) );
		
		}
		
		// If recognised type return video array
		if ( !empty( $video_type ) ) {
		
			$video_array = array(
				'type' => $video_type,
				'id' => $video_id
			);
		
			return $video_array;
			
		} else {
		
			return false;
			
		}
		
	}
	
	
	 /* Takes a Vimeo video/clip ID and calls the Vimeo API v2 to get the large thumbnail URL.
	 */
	function get_vimeo_thumbnail_uri( $clip_id ) {
		$vimeo_api_uri = 'http://vimeo.com/api/v2/video/' . $clip_id . '.php';
		$vimeo_response = wp_remote_get( $vimeo_api_uri );
		if( is_wp_error( $vimeo_response ) ) {
			return $vimeo_response;
		} else {
			$vimeo_response = unserialize( $vimeo_response['body'] );
			return $vimeo_response[0]['thumbnail_large'];
		}
		
	}
	/**
	 * Takes a wistia oembed url and gets the video thumbnail url.
	 */
	function get_wistia_thumbnail_uri( $video_uri ) {
		if ( empty($video_uri) )
			return false;
		$wistia_api_uri = 'http://fast.wistia.com/oembed?url=' . $video_uri;
		$wistia_response = wp_remote_get( $wistia_api_uri );
		if( is_wp_error( $wistia_response ) ) {
			return $wistia_response;
		} else {
			$wistia_response = json_decode( $wistia_response['body'], true );
			return $wistia_response['thumbnail_url'];
		}
		
	}
	

And then in your template file choose one:

For Single Field:

<?php
										//For use with a single field.
										
									 $video = get_field('video'); //Embed Code
									  $video_url = get_field('video', FALSE, FALSE); //URL
									  
									  
									  $video_thumb_url = get_video_thumbnail_uri($video_url); //get THumbnail via our functions in functions.php ?>
									  
									  
									  <?php //Lightbox Link via Thumbnail ?>
										<a href="#lightbox"><img src="<?php echo $video_thumb_url; ?>"/></a>
										
										<?php //Lightbox Element with Video Embed Code ?>
										<div id="lightbox" class="embed-container">
										<?php echo $video; ?>
										</div>
										
										

For Repeater Field:

							
									
							<?php
								//For Use with Repeater Field 
								 $videos = get_field('videos');
								 $videos_raw = get_field('videos', FALSE, FALSE);
									
								
								//Add the Thubmnail to the $videos object
									
									foreach($videos_raw as $key => $video_raw) : 
								
											$videos[$key]['video_thumb'] = get_video_thumbnail_uri($video_raw['field_5449746362c3d']); //Replace 'field_5449746362c3d' with your field's Field key (obtainable by going to screen options in the fields admin, and setting 'Show Field Key' to 'Yes')
								
									endforeach;
									
								
								
								//Loop through the $videos object
									foreach($videos as $video): ?>
									
										<?php //Lightbox Link via Thumbnail ?>
										<a href="#lightbox"><img src="<?php echo $video['video_thumb']; ?>"/></a>
										
										<?php //Lightbox Element with Video Embed Code ?>
										<div id="lightbox" class="embed-container">
										<?php echo $video['video'] ?>
										</div>
									
									<? endforeach; ?>

Writing from my phone, but I got this going, using this as a reference to write my own function:

https://github.com/FindingSimple/acf-field-video/blob/master/video.php

in conjunction with this:

http://support.advancedcustomfields.com/forums/topic/getting-just-the-url-that-was-entered-into-an-oembed-field-inside-a-variable/

Ill try to post more of what i ended up with tomorrow.
