Hello everyone! Following up on Part 1, we will be diving into more detail on the Text-to-Video generation process—specifically text-based video creation—by presenting a case study of the daily stock market news developed by the LETR WORKS research team.
📈K-Stock AI Briefing
Our research team embarked on the development of 'K-Stock AI Briefing,' which can be described as a daily summary of the Korean stock market news. In the securities market, stock prices fluctuate daily based on various situations and variables. As the number of stock investors grows, so does the curiosity about today's market conditions.
To address these curiosities and provide accurate information, media organizations are putting in significant effort. In particular, short-form content like 'Today's Stock Market Summary,' typically 2-3 minutes long, is gaining considerable popularity on platforms such as YouTube.
Focusing on this trend, we researched K-Stock Briefing content incorporating AI technology. This short video, lasting 3-4 minutes, covers the day's Korean stock market trends, indices, major economic news, and stocks to watch.

📊Video Content Structure
Typical investors are generally interested in stock market index fluctuations, price changes of their holdings, and recently spotlighted industries or stocks. Through collaboration with a specialized stock market analysis institution, we were able to secure content in the form of text documents.
Based on this foundational content, we structured the video into three main sections and a summary:
Section1 : Stock Market Briefing (Today’s Market Summary)
Section2 : Key Issues (Today’s Major News)
Section3 : Market Issues (Hot Industry and Stock News)
Summary : Market Takeaways (Today’s Core Summary)
Crucially, our collaboration with the specialized institution allowed us to identify the main interests and relevant issues of stock investors, enabling us to plan content that is truly useful from an investment perspective.

🤝Production Through Collaboration Between AI and Human Experts
As we discussed in Part 1, if this content had been produced using traditional workflows by a professional video company, it would have involved complex procedures—running from planning and shooting to editing and post-production (subtitling/dubbing, etc.). However, we were able to significantly simplify this by leveraging AI technology.
First, we utilized an AI model to generate the video directly from the text document. The on-screen anchor is not a real person but a virtual presenter.
Subsequently, a specialist from our research team applied AI voice technology to the video, making it sound as if a real anchor were reporting the news, while also synchronizing the virtual anchor's lip movements with the audio to enhance realism. Furthermore, we boosted the overall quality by adding graphics and sound effects to the video.
In the section introducing specific industries and stocks, we included additional graphics and charts to better illustrate the anchor's explanations, aiding viewer comprehension. We also carefully placed dynamic music and sound effects to maximize the sense of immediacy and vibrancy.

We paid particular attention to the collaboration between AI technology and human experts during the production phase. This is because video generation technology cannot perfectly implement the user's intent 100% of the time. Therefore, a specialized expert who is familiar with the video production process was assigned the task of reviewing, modifying, and supplementing the AI-generated content.
Initially, our specialist faced some challenges, but we subsequently established standardized procedures to ensure efficient workflow. Through this iterative process, we are accumulating the necessary know-how for effective collaboration between AI and human expertise.
Moving forward, through the K-Stock AI Briefing project, we aim to produce videos not only in Korean but also in various other languages. This effort will contribute to promoting the attractiveness of K-Stock and related news to a large number of overseas investors. Furthermore, we will continue to advance the Text-to-Video technology and integrate it into LETR WORKS, striving to enable many people to enjoy more engaging and useful videos across diverse sectors!
Through this two-part series, we have briefly introduced the technology and case study of text-based AI video generation, focusing on the K-Stock AI Briefing project. We look forward to seeing you next time with more valuable content.
Thank you!
