This hour is used to measure the distance/time into your program based on the timecode you enter. The app defaults to Hour 1 (which is the starting timecode for most feature video tapes/files). The other three equivalents will be displayed below. Video editors can keep proper cadence as Timecode Tool displays the location of A-Frames that occur during each minute of interlaced video based on a given start-time.įuture versions of Timecode Tool will include a timecode calculator and, if requested, 35/16mm film footages.Īlthough this app converts between 23.98, DF, NDF, & PAL timecodes, you will need to select one as your source. After entering that file's current length, target length, and current sample rate, a simple math calculation is performed and the user is provided with the numbers necessary to import that file at a custom rate where it should stay in proper sync. Example: you may have an audio file that is 20 frames shorter than it is supposed to be. Both the difference in percentage and the correct sample rate necessary to vari-speed (VSO) when importing/exporting are provided. The hope is that you are using a software program that allows you to convert your audio by entering a specific sample rate ("Import Audio"). The second feature of Timecode Tool helps the user vari-speed audio that is currently running at the wrong speed. (A future version may allow the user to select a specific "non-even hour" timecode if there are enough requests) It has a default value of 1 Hour as the starting time of your program material but the other 23 even hours can be selected if necessary. How do you find the same spot in the NTSC version? Timecode Tool will easily allow you to enter the PAL timecode of 2:14:30:23 and will return to you the equivalent 23.98, DF, and NDF timecodes. Perhaps you are performing a QC pass on a PAL version of a feature film and find an issue at 2:14:30:23. PAL video runs at a faster speed than NTSC and consequently causes issues when trying to find the same spot in a feature film between those standards. ![]() The title start time and duration are encoded in milliseconds using a time-fraction that referrers to the frame-rate of the sequence (which is written in the header of the file).įor example, for a 24pfs timeline, the header info would be : frameDuration=”1/24s”Īnd each title would have specific timing information like: title duration=”76/24s” and start=”596/24s”įCP then converts this information into timecode on import.The primary feature gives the user the ability to convert between 23.98, DF, NDF and PAL timecodes. There are some free online tools that can do this as well.įormats that use timecode: AVID DS, video editing programsįCP XMLs (both FCP7 and FCPX) use a combination of timestamp and timecode to import and export title information from the editing application. Some editing application can handle such transfers though various strategies, but overall, it is better practice to retime the subtitles to the new timecode using a subtitling program. Let’s say you have an 29.97fps video transcoded to 25fps, it is unlikely that the subtitles will transfer correctly from one timeline to another. The disadvantage of this format is that it is not compatible across different frame rate timelines. The timecode tells the editing application where to put the text box in-point and out-point on the edit timeline. The video playback happens on a timeline at a specific frame rate. This method is used for timing subtitles within editing applications. The timecode of the uploaded video is irrelevant to the timing of the subtitles, the subtitles appear at a specific global time ensuring compatibility across a wide-range of video formats.Įxample (AVID DS): 10:01:07 27 10:01:09 02 ![]() One common usage for SRT timestamp title is to display closed captioning on YouTube videos. Timestamp has the advantage of being timecode independent and is used in subtitling systems that operate in parallel to the video display. ![]() This method encodes time in milliseconds. Subtitles are timed to appear on screen at specific times.ĭepending on the video format and the subtitle display method, the timing can be encoded in either Timecode or Timestamp.Įxample (SRT): 00:00:04,204 –> 00:00:10,143 ![]()
