The computation of word votes is determined by the proximity of words to each other in a sentence. Essentially, each unique word has a fixed amount of votes that it can split between other words in the transcript. This algorithm is derived from the same method that Google uses to rank web pages in its search results (called PageRank). Next, we determine which words are important to the transcript by letting the words themselves “vote” in an algorithm called TextRank 1. These results are treated only as suggestions at this point no hard decisions are made other than to eliminate stop words. For example, proper nouns, words near the beginning and end of a document, and unique numbers (such as calendar years) can be given high priority. The first step is to determine which words are more likely to be important to the transcript using several heuristically defined features often used in supervised machine-learning.
Here is how it works: Step 1 –Determine the Most Important Words Using Heuristics While this is a good starting point, our approach goes much further by using natural language processing to prioritize words based on their linguistic importance in the transcript. Not only will correct timestamps make it easier to reference the right parts of the video, but it will also help you pace your transcription should you use it for subtitles or captions.Transforming Video SEO with Transcripts and CaptionsĪ common, easy strategy to automatically generate keywords from a video transcript is to simply find the words that appear most frequently, while ignoring a known list of common but not-too-interesting words (called “stop words”), such as “and” and “the”.
Once you’ve finished converting the video to text, watch the video through one last time, paying attention to the timestamps on your transcript. However, if you’re creating the transcription from a video in order to make subtitles or captions, you should also note important context like a slammed door or the creepy footstep from someone who’s out of frame. If you intend to use the video transcript for notes or to pull quotes from, the dialogue is enough. You want to pay attention to details beyond what the speaker is saying. Write what you hear as you’re watching the video. As you get better, you can start to listen to longer segments, but you want to practice for accuracy, not speed, as you’re learning. When you watch the video, try to watch it in increments of 10 or so seconds. Make sure you have access to the video and a word processor (you can even write it by hand if you’re brave enough)! 1. As we mentioned, it’s a very low barrier to entry if this is a skill you’re hoping to pick up. To create a transcript from a video yourself, you’ll only need a few things before you begin.
