RAG vs. Traditional Search: Why AI is the Future of Video Retrieval

Following the sudden growth of video content across media, entertainment, and broadcasting industries, search and retrieval of relevant video data are becoming tedious. Current methods that have been very effective in understanding and retrieving text-based content tend to fall apart when applied to the same with video content.  In this regard, it is AI Frameworks, such as Retrieval Augmented Generation (RAG), that will change the way video search is handled.

At Gyrus, we specialize in AI-driven solutions for video processing, and RAG happens to be one of those frameworks that we think might redefine the future of video retrieval.

So, what makes RAG more performative than traditional search methods within the domain of video?

What does RAG do?

RAG combines the strengths of traditional information retrieval systems (such as search and databases) with the capabilities of generative large language models (LLMs). Unlike traditional search engines, which rely on the keyword matching of metadata or tags, RAG combines your data and world knowledge with LLM language skills. Grounded generation is more accurate, up-to-date, and relevant to your specific needs.

This hybrid approach is especially useful in video retrieval, where both the context of visual and audio content must be understood. Traditional search engines often do not provide specific results when users are searching for specific scenes, actions, or spoken content within a video. RAG overcomes these challenges by combining retrieval with AI-generated insights.

Why AI is the Future of Video Retrieval

Traditional Video Search: What’s the Limit?

1. Keyword Dependency: Traditional video search engines are keyword-dependent; they use metadata, tags, or manually created descriptions. In the absence of the appropriate keywords, the result does not match what the user is searching for.

2. Lack of Context: Traditional systems fail to understand complex queries or even know what a user is trying to express. It is almost impossible to search for a specific event in a video using the natural language description with conventional search methods.

3. Manual Effort: Tagging and annotating videos by hand are extremely time-consuming, human-error-prone operations that yield inconsistent and incomplete data, making retrieval difficult

4. Limited Personalization: Standard search engines offer very little or no personalization. That is, two different individuals searching for the same exact query would get exactly the same results, independent of those users’ viewing preferences and history.

How RAG Changes Video Search?

RAG changes video search by solving the shortcomings through AI power for contextual understanding and retrieval. Here’s how:

RAG changes video search

1. Contextual Understanding of Videos:

Beyond metadata, RAG can analyze video content. It extracts information from both video frames and audio transcripts. This allows users to search for specific scenes, dialogues, or even visual elements such as objects or locations within the video. For instance, a broadcaster might be looking for all instances of a specific brand logo or a certain phrase spoken in a video archive, and RAG would deliver those exact clips.

Unlike that list of links or video files, RAG produces full, human-like answers relevant to the user’s question, providing relevant snippets or timestamps within videos so you can jump directly to that part of the video where it matters.

2.Easier Video Discovery:

RAG ends the limitation of basic search in video retrieval. Now, users can pose questions in complex, open-ended queries and get the exact answer. For example, “Find all interviews that discussed AI trends from last year” would not just retrieve video files but would fetch the exact segments where AI trends were mentioned.

3. Real-Time Updates & Personalization:

It can be used to integrate existing, updated databases for easy accessibility to current information. It learns based on user preferences in video searching and returns a list of results more oriented toward viewing habits; thus, it makes video searching even more intuitive and easy.

Some of the challenges RAG faces in its video search include

1. High Computational Demands:

The model requires very large-scale computational resources for processing video data paired with very large-scale AI models. High volume real-time video search can strain a system without an appropriate infrastructure.

2. Accuracy Concerns (Hallucinations):

Like other AI models, RAG is not immune to generating inappropriate or misleading results, especially when video content is sparse or incomplete. AI-generated “hallucinations” can still occur, providing confident yet incorrect responses.

3. Scalability:

Video libraries growing in size are not easy to scale the RAG systems to efficiently handle large databases. Video files are larger and more complex than text documents and require more sophisticated storage and processing capabilities.

Is RAG Ready to Replace Traditional Video Search?

RAG Ready to Replace Traditional Video Search

While RAG has made a tremendous stride in video retrieval, for certain applications, traditional search engines cannot be replaced entirely. Conventional systems can still outperform in basic searches, metadata-based queries, and large-scale browsing of video archives. However, if users require specific, contextual, or personalized video results, then RAG is clearly ahead.

At Gyrus, we consider RAG a complement to traditional search, rather than a replacement – at least for now. Users would be able to combine conventional search engines with RAG to benefit from the exhaustive breadth of traditional search combined with the depth of AI-driven video retrieval.

Future of Video Retrieval with RAG.

The future of video retrieval, as the RAG technology continues to advance, looks bright. Here is what is to be expected in the future:

1. Tighter Integration:

RAG would be an integral part of video management systems and search engines that would refine video discovery for media companies, broadcasters, and streaming platforms.

2. Specialized Applications:

RAG will be particularly useful in industries where video content is of prime importance, such as media & entertainment, healthcare, and surveillance. For example, media companies can use RAG to quickly locate relevant news clips, while healthcare professionals might retrieve specific segments of medical video footage for research or training.

3. AI-Driven Personalization:

The more advanced these AI models become, the more personalized the video search will be on RAG because results will be targeted specifically at the preferences and browsing history of the user themselves, which accelerates how one discovers content.

4. Live Video Indexing:

That day when the world starts to index videos live such that a viewer will immediately know what he is seeking within a running broadcast-when that day comes without post-production, I’m home.

Conclusion:

Clearly, RAG is the future of video retrieval because it initiates a new AI-based approach. How people find and engage with video content is changing and provides the opportunity for new use cases for AI Video broadcasters, streamers, and other media companies dealing with huge volumes of video data. It certainly cannot replace traditional search currently, but it has extremely significant potential for the future of video retrieval, where it can provide contextual, precise results.

We at Gyrus are very proud to be a part of this change, enabling companies to unlock the power of AI in making video search smarter, faster, and more intuitive.
