![]() black and white.įrame rate is important for SMPTE timecode because it dictates how many frames per second (fps) appear in the media. 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. SMPTE timecode appears as hour:minute:second:frame (for example, one hour would be written as 01:00:00:00). 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. SMPTE timecode is a standard for labeling frames of video or film. Let’s begin by explaining SMPTE timecodes in more detail.Ĭaptioning Best Practices for Media & Entertainment ➡️ SMPTE-based captions are most commonly required for the digital distribution of broadcast media. If you are using an SMPTE-based timecoded caption format, then you may need to take into consideration specific frame rate settings. After reading this blog, you’ll have the knowledge you need to utilize DF and NDF for captions and to even teach others about it.įirst, you should know that video is measured in invisible units called frames, and the frame rate is the rate at which a video plays back frames. If you want to reset your timecode entries, hit the button called RESET.If you’ve never heard of drop frame (DF) timecode or non-drop frame (NDF) timecode, that’s no problem. You can copy the result to your clipboard by clicking on the button named COPY. The results consist of three elements: the result timecode, the used frame rate, and the frame count of the timecode result. If your timecode calculation succeeds, TC Calc will show you a result in the result section. In that case, TC Calc will highlight the corresponding element of the concerning timecode and inform you what went wrong by showing you an info text in the result section, describing the problem. You can copy and paste the timecode into the timecode fields as well.įurthermore, suppose you typed in values that are not allowed in the timecode. As you will notice, TC Calc is very reactive and immediately shows results while you type in the timecodes. As the third step, you fill in the two timecodes. If you have selected the subtract method, TC Calc subtracts the timecode above from the timecode below. Second, you can choose to add two timecodes or subtract one timecode from the other (defaults to addition). First, you choose the desired FPS your calculations should take place (defaults to 24 FPS). The usage of TC Calc is quite simple and follows easy steps. They rather skip the first two frame counts in the timecode on the first second in each minute, but not if the minute count is divisible by ten. All other FPS choices use non-drop-frame timecodes (NDF).īut what are DF timecodes? Easy, drop-frame timecodes don't skip actual frames as the name might suggest. The DF-suffix on 29.97 and 59.94 mean drop-frame and indicate that those two timecodes use the drop-frame method for showing timecodes. TC Calc works with timecodes of different frame rates per second (FPS). The timecodes it processes are SMPTE-conform timecodes used in the motion picture industry. TC Calc is a timecode calculator which enables you to add or subtract two different timecodes. ![]()
