If you are using an SMPTE-based timecoded caption format, then you may need to take into consideration specific frame rate settings. SMPTE-based captions are most commonly required for the digital distribution of broadcast media.<\/p>\n<p>Let\u2019s begin by explaining SMPTE timecodes in more detail.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><a class=\"btn btn-blue-blank\" href=\"https:\/\/go.3playmedia.com\/wp-best-practices\" target=\"_blank\" rel=\"noopener noreferrer\">Captioning Best Practices for Media &amp; Entertainment \u27a1\ufe0f<\/a><\/p>\n<p>&nbsp;<\/p>\n<h2><b>What Is SMPTE Timecode?<\/b><\/h2>\n<p><a href=\"https:\/\/www.studionetworksolutions.com\/decoding-timecode-standards-in-video-production\/\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>SMPTE timecode<\/strong><\/a> is a standard for labeling frames of video or film. The standard was developed and defined by the Society of Motion Picture and Television Engineers (hence the name SMPTE) and allowed for accurate editing, synchronization, and identification of media.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignleft wp-image-25871 size-thumbnail\" src=\"https:\/\/www.3playmedia.com\/wp-content\/uploads\/3-7-150x150.jpg\" alt=\"Drop frame timecode icon with film and clock\" width=\"150\" height=\"150\" srcset=\"https:\/\/www.3playmedia.com\/wp-content\/uploads\/3-7-150x150.jpg 150w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/3-7-300x300.jpg 300w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/3-7-75x75.jpg 75w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/3-7.jpg 165w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/3-7.jpg 220w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/3-7-174x174.jpg 174w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/3-7.jpg 500w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/>SMPTE timecode appears as hour:minute:second:frame (for example, one hour would be written as 01:00:00:00). The frame rate is derived directly from the data of the recorded medium; in other words, the frame rate is inherent to the media and can differ for film vs. digital, video vs. audio, and color vs. black and white.<\/p>\n<p>Frame rate is important for SMPTE timecode because it dictates how many frames per second (fps) appear in the media. The final part of the SMPTE timecode reflects the frame number; this number can only go as high as the frame rate. For instance, if your frame rate is 29.97 fps, the timecode after hh:mm:01:29 would be hh:mm:02:00.<\/p>\n<p>The following chart reflects the <strong><a href=\"https:\/\/www.bhphotovideo.com\/c\/find\/newsLetter\/Frame-or-Non-Drop-Frame.jsp\" target=\"_blank\" rel=\"noopener noreferrer\">frame rate standards developed by SMPTE<\/a><\/strong> (as well as the European standards developed by the European Broadcasting Union, EBU):<\/p>\n<hr \/>\n<div align=\"\u201ccenter\u201d\">\n<table style=\"background-color: #ffffff;\" border=\"1\" summary=\"\u201cFrame\" width=\"100%\" cellspacing=\"\u201c0&quot;\" cellpadding=\"3\">\n<tbody>\n<tr>\n<th style=\"text-align: center;\" colspan=\"5\"><strong>SMPTE (Society of Motion Picture and Television Engineers)<\/strong><\/th>\n<\/tr>\n<tr>\n<td>29.97 fps<\/td>\n<td>NDF<\/td>\n<td>Color<\/td>\n<td>60Hz<\/td>\n<td>Non-Real Time<\/td>\n<\/tr>\n<tr>\n<td>29.97 fps<\/td>\n<td>DF<\/td>\n<td>Color<\/td>\n<td>60Hz<\/td>\n<td>Real Time<\/td>\n<\/tr>\n<tr>\n<td>30 fps<\/td>\n<td>NDF<\/td>\n<td>Black &amp; White<\/td>\n<td>60Hz<\/td>\n<td>Real Time<\/td>\n<\/tr>\n<tr>\n<td>59.94 fps<\/td>\n<td>NDF<\/td>\n<td>Color HD<\/td>\n<td>60Hz<\/td>\n<td>Non-Real Time<\/td>\n<\/tr>\n<tr>\n<td>59.94 fps<\/td>\n<td>DF<\/td>\n<td>Color HD<\/td>\n<td>60Hz<\/td>\n<td>Real Time<\/td>\n<\/tr>\n<tr>\n<td>60 fps<\/td>\n<td>NDF<\/td>\n<td>Color HD<\/td>\n<td>60Hz<\/td>\n<td>Real Time<\/td>\n<\/tr>\n<tr>\n<th style=\"text-align: center;\" colspan=\"5\"><strong>EBU (European Broadcasting Union)<\/strong><\/th>\n<\/tr>\n<tr>\n<td>25 fps<\/td>\n<td>NDF<\/td>\n<td>Color<\/td>\n<td>50Hz<\/td>\n<td>Real Time<\/td>\n<\/tr>\n<tr>\n<td>50 fps<\/td>\n<td>NDF<\/td>\n<td>Color HD<\/td>\n<td>50Hz<\/td>\n<td>Real Time<\/td>\n<\/tr>\n<tr>\n<th style=\"text-align: center;\" colspan=\"5\"><strong>Film<\/strong><\/th>\n<\/tr>\n<tr>\n<td>24 fps<\/td>\n<td>NDF<\/td>\n<td>Color<\/td>\n<td>N\/A<\/td>\n<td>Real Time<\/td>\n<\/tr>\n<tr>\n<td>23.98 fps<\/td>\n<td>NDF<\/td>\n<td>Color HD<\/td>\n<td>60Hz<\/td>\n<td>Non-Real Time<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<hr \/>\n<p>Keep in mind that a <strong><a href=\"https:\/\/wistia.com\/learn\/production\/what-is-frame-rate\" target=\"_blank\" rel=\"noopener\">faster frame rate during shooting will produce slower motion during playback<\/a><\/strong>.<\/p>\n<hr \/>\n<p style=\"text-align: center;\"><span style=\"font-weight: 400;\"><span class=\"su-highlight\" style=\"background:#DEEFF5;color:#000000\">&nbsp;<a href=\"https:\/\/go.3playmedia.com\/wp-best-practices\" target=\"_blank\" rel=\"noopener\">Learn about closed captioning for TV and film \ud83c\udfac<\/a>&nbsp;<\/span>\u00a0<\/span><\/p>\n<hr \/>\n<h2><b>The Origins of Drop Frame Timecode<\/b><\/h2>\n<p>Initially, black and white video ran at 30 fps. When color video was introduced, the <a href=\"https:\/\/www.bhphotovideo.com\/c\/find\/newsLetter\/Frame-or-Non-Drop-Frame.jsp\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>frame rate slowed to 29.97 fps<\/strong><\/a> to allow color television to run on black-and-white receivers. This created a disparity between real-time and video time, as a fraction of a frame cannot be produced in one second. This means that for every 100 seconds, there will be 2997 frames instead of 3000, creating a lag between video time and real time. For example, after 60 real-time minutes, a video playing at a frame rate of 29.97 fps will only read 00:59:56:12.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-thumbnail wp-image-25872\" src=\"https:\/\/www.3playmedia.com\/wp-content\/uploads\/5-4-150x150.jpg\" alt=\"Television icon\" width=\"150\" height=\"150\" srcset=\"https:\/\/www.3playmedia.com\/wp-content\/uploads\/5-4-150x150.jpg 150w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/5-4-300x300.jpg 300w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/5-4-75x75.jpg 75w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/5-4.jpg 165w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/5-4.jpg 220w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/5-4-174x174.jpg 174w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/5-4.jpg 500w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/p>\n<p>Drop frame (DF) timecode was introduced in an attempt to make 29.97 fps video indicate real-time to alleviate this disparity. DF does not actually remove any frames from your video; instead, it effectively drops a frame number every time the remaining .03 of a frame adds up to a full frame (once every 33.33 seconds).<\/p>\n<p>In one hour, the difference between a 30 fps video and a 29.97 fps video is 108 frames. So, within that hour, DF video removes 108 frame numbers so that a 29.97 fps video will finish at 01:00 instead of 00:59:56:12. Two frame numbers are removed per minute, except every 10th minute, to make the video 108 frames shorter, allowing the video to end in real time.<\/p>\n<h2><b>Drop Frame vs. Non-Drop Frame Captions<\/b><\/h2>\n<p>Not all 29.97 fps video is drop frame. Some videos are non-drop frame (NDF), which means that the timecode does not account for the difference in video time vs. real time.<\/p>\n<p>If you are captioning your video, it is important to know whether your <a href=\"https:\/\/www.3playmedia.com\/2014\/05\/07\/closed-caption-subtitle-frame-rates-digital-distribution-tv-film\/\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>video file is drop frame or non-drop frame<\/strong><\/a> so that your captions are accurately synced with the timing of the media. At the end of a real-time hour, a DF video will have run 01:00, while a NDF video will have run 00:59:56:12. If you caption a DF video with NDF captions, the captions will not be synced with the video and will get more and more out of sync as time goes on.<\/p>\n<p>Another difference between DF and NDF is that NDF files are written with all colons (hh:mm:ss:ff) while DF files are written with either a semi-colon or a period between the seconds and frames (hh:mm:ss;ff or hh:mm:ss.ff).<\/p>\n<h2><b>How to Download Captions with the Correct Frame Rate Settings<\/b><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-thumbnail wp-image-25870\" src=\"https:\/\/www.3playmedia.com\/wp-content\/uploads\/4-3-150x150.jpg\" alt=\"Movie file icon\" width=\"150\" height=\"150\" srcset=\"https:\/\/www.3playmedia.com\/wp-content\/uploads\/4-3-150x150.jpg 150w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/4-3-300x300.jpg 300w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/4-3-75x75.jpg 75w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/4-3.jpg 165w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/4-3.jpg 220w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/4-3-174x174.jpg 174w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/4-3.jpg 500w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/p>\n<p>For captioning, you must determine the frame rate of your video timeline.\u00a0Next, you must determine whether your project\u2019s timeline is DF or NDF so the timing of your captions matches the run time of your video.
