Video summarization services in multiple languages

With Automatic Speech Recognition and transformation or machine learning models, it is now possible to simply generate a summary and extract information from video files.

Why should you use video summarization?

Summarization has many use cases, with one of the most significant being the ability to gauge interest in the content. A flashcard summary can determine how many people will actually watch an entire video. Many people don’t have time to watch an entire video, but they will take the time to watch a video summary. After reading the summary of the video, users can make immediate judgments on its usefulness.

There are also several reasons why video summarization makes sense:

. Video summarization is necessary for efficient viewing on other channels, such as on Instagram, Facebook, and the others.

. In this age of the internet, we all skim websites. We don’t always have the patience to read through everything, and we normally focus on what captures our attention.

. Busy professionals know that shorter is better. If the video content is valuable, your clients will love you for it.

. Video summarizes are cheaper to translate. You can reach a wider audience.

. A shorter content is a mobile/social media friendly format.

Two ways to produce video summaries

The techniques used to produce video summaries can be divided into two broad categories:
– Abstractive video summarisation
– Extractive video summarisation

Extractive video summaries

The extractive summary approach extracts the sentences that are most relevant to the given information (text, video, audio, etc.).

Abstractive video summaries

The abstractive technique allows for the generation of a summaries using Natural Language Processing (NLP) methods. It is the approach we have adopted at LenseUp.

Possible uses of video summaries

– Video platforms – Automatically create “video chapters” to make it easier to navigate through videos and allow users to go directly to the content they are looking for. Chapters allow you to divide a video into sections, and each section has a different preview associated with it.

– Virtual meeting platforms – Provide summaries of a meeting and make recording a meeting less demanding.

– Telephony – Make it easy to view phone calls, especially for quality assurance in contact centres.

– Reuse existing video content – summarise a one-hour video webinar (approx. 10,000 words) and convert it into a blog post (approx. 1000 words).

– Conference or congress summaries – nowadays many conferences are broadcasted on-line, so why not take the opportunity to summarise them for publication in written form?

Summaries to reduce costs of video translations

Translating a video into other languages can be expensive. There’s a lot of work involved in the translation of videos. If you convert 40 minutes of video, that’s between 6000 and 7000 words to translate. The average word rate is 7 cents. Translation can be costly, especially when converting a long video into several languages.

In today’s world, companies are doing everything they can to reduce expenses. A 7000 word video can be summarized in 1000 words, resulting in a significant reduction of translation costs. Video audio summaries allow brands to reach international audiences quickly and cheaply.

Summarization of audio files: how do we work?

First, we use a Speech to Text technology to convert human voice into written words. Then we generate a summary, and extract themes and insights using transformers and machine learning-based models.

The client sends us a video file.
Audio is extracted from the video.
Audio is transcribed using Speech to Text technology
The text is then processed to extract a summary, keywords and prominent topics.
Translation. Summarized audio files are translated, when needed, by native translators.
The final summary is delivered
