![]() They have multiple uses, usually ones that require frame-accurate or millisecond-accurate timings. Time-codes are often gathered for captioning and subtitling, it’s crucial to note that this isn’t always the case. Unlike time-stamps, though, time-codes are always frame-accurate – that is to say, they also contain frames or milliseconds, and follow a particular format. Time-coding refers to gathering actual timing information as well. Because of this, time-stamp content, interval length, and format can vary, sometimes substantially. Remember that time-stamps are generally used to help humans navigate through long audio and video files – therefore, they don’t have to be more accurate than minutes and seconds, and they’re attuned to what people actually need to find. Same thing with court transcriptions of testimony – lawyers can use the time-stamps to find the exact audio and video they want to play for a jury. For example, on documentaries directors write editing instructions on the time-stamped transcriptions, which editors can then use to find the footage relatively easily. Here, the time-stamps just note when the footage gets to the 30-second and 1-minute mark – these particular ones are are added in 30-second intervals.īoth kinds of time-stamps – event and interval-based – are useful for finding content in the source footage. Time-stamps can also be in intervals, as in the following example: In this case that event is a “change of speaker,” but it can be many things, like time-stamping every question in an interview, or time-stamping when a specific person appears in the footage, or when someone speaks in a foreign language, etc. These time-stamps are event-based, meaning that they are inserted every time a specific event happens in the video. Note that there are red time-stamps indicating when the speaker changes, at 12, 18 and 24 seconds: The following example is a transcription from an interview video. Usually the time-stamps just contain minutes and seconds, though they can sometimes contain frames or milliseconds as well. The time-stamps can be added at regular intervals, or when certain events happen in the audio or video file. This refers to the process of adding timing markers – also known as time-stamps – to a transcription. If you’re unfamiliar with time-codes in general, you should check out our previous post, What are time-codes? Do they matter? (Yes!) – it’s good reading before delving into this post, in particular if you don’t understand time-code formats, which will be discussed at length. ![]() ![]() What kind of information is added, as well as how it’s added, is what makes them different. In general, all three processes involve one thing – adding some kind of timing information to a transcription of the voice-over or other sound elements in audio or video files. This post will explain time-stamping, time-coding and spotting, how they’re used, and what you need to know to source the correct one for your project. Knowing these differences, and their application, is crucial for the success of video localization projects. The terms also get confused with each other, not least because they refer to similar processes – with critical differences. Time-stamping, time-coding, and spotting are all crucial parts of audio and video workflows, especially for captioning and subtitling services and translation. ![]()
