Why use an AI video summarizer?

An AI video summarizer makes it super easy and convenient to consume video content efficiently without getting drowned in a sea of content. 

This is beneficial in many ways, such as:

• Saving you time with research

• Helping you consume large volumes of video content

• Helping you curate new ideas from key points and summaries

• Accessing a video on the go, wherever and whenever you need

How does AI summarization work?

The AI models and algorithms used by most of these tools are generally similar.

1. AI processes the video. 

2. It then extracts the important features (like scenes, activities, and sound effects) from each frame.

3. Then, it segments the video into meaningful chunks or chapters.

4. It assigns importance scores to different segments or frames, and based on this, it selects the key points.

5. The selected content is compiled into a shorter version of the original video

6. Natural language processing (NLP) algorithms are used to transcribe and analyze the speech.

What makes a good video summarizer?

A good video summarizer should be accurate, budget-friendly, and have a fast turnaround time. Even though there are millions of AI summarizers available, you should consider a few important things before choosing the right one for you. 

• Easy-to-use user interface: You'll need to ensure the speech-to-text software is user-friendly. It should have an easy-to-navigate interface that helps you quickly upload and summarize your videos. 

• Accuracy level: Selecting an AI tool with a high accuracy rate will help you eliminate time spent proofreading and editing the generated summary. 

• Responsive customer support: Your choice of tool should provide real-time customer support via phone, email, live chat, or self-service, in case you run into any issues.

• Emotion and sentiment detection: Opt for a summarizer that can detect the emotions and sentiments of the speakers. This will make the summary even more insightful and comprehensive.

• Customization: You should be able to tailor your summaries to meet your specific needs. This includes presenting the summaries in set templates and choosing the focus areas you need the summary for.

• Supports multiple languages: Make sure the summarizer supports multiple languages. This is especially handy when you have a global and diverse workforce.

Real-time capabilities: Check if the tool summarizes in real time.. Additional features like live meeting transcription and summary generation can be extremely beneficial, too.

Tips for summarizing videos

Generating summaries isn’t only about understanding the gist of an hour-long video. Summaries should ensure you don’t miss any of the key points discussed in the video. Here are some of my best tips for summarizing videos.

Create a goal

First, you should be clear about how you want to condense the content and any questions the summary should answer. 

Additionally, determine the purpose of the summarization process—educational, marketing or entertainment. This clarity helps you decide the format and depth of your summary to ensure it meets the specific needs of your viewers.

Adapt the length

What does your audience need to know? How will they consume your content? When you know the answer to these questions, you’re sure to create a summary that’s both informative and appropriately condensed.

Adjust the length of the summary based on the audience and the delivery format. For example, a blog post might allow for a detailed summary over several paragraphs, while a social media post would require a concise bullet point list. 

Add keywords to your summary

Include keywords in your summary so Google and other search engines identify the content of your video and rank it appropriately. This makes it easier for users to find it through search queries.

Create pages for summarized videos

Create dedicated pages for your videos and their summaries on your website. This helps to organize your content and makes it more accessible and searchable for users.
