AIで作るハイクオリティな動画生成入門編！Midjourneyで作った画像を高品質にしてRunwayGen2で動かすテクニックを紹介！

The speaker, Norihiko, introduces the topic of using AI to create high-quality video content. He mentions a channel dedicated to explaining how to utilize generative AI for work and keeping up with the latest trends. Norihiko suggests that the goal is to make the audience find AI interesting and encourages them to watch the video until the end. He discusses the potential of the video industry undergoing a significant transformation in 2024 with the introduction of AI video generation tools like 'Sora,' which has generated a lot of excitement despite not being released yet. The speaker proposes that learning about AI video generation now could be beneficial to avoid falling behind once these tools become widely available.

The speaker proceeds to explain the process of creating images using an image generation AI called 'M Journey' and then transforming those images into videos. He emphasizes the importance of learning the basics of AI video creation to be prepared for when tools like 'Sora' are released. Norihiko demonstrates how to use 'M Journey' by creating an image of a woman in a kimono, detailing the process of inputting prompts and generating the image. He also discusses the aspect ratio considerations for video creation and suggests ways to enhance the quality of the generated images, such as adjusting the resolution and clarity.

The speaker talks about the desire to make the generated images more vivid and high-quality before turning them into videos. He introduces a free tool for upscaling images to enhance their resolution and clarity, which significantly improves the final video quality. Norihiko demonstrates the upscaling process using an image of a handsome samurai, showing the before and after results, and highlighting the dramatic improvement in realism and detail. He also discusses the potential for further enhancing the images by adjusting various aspects such as hair, facial features, and adding a sense of depth and realism.

The speaker moves on to the next stage of video creation, which involves animating the static images using 'Raway G2.' He explains the process of selecting parts of the image to animate using motion brushes and demonstrates how to adjust the position, scale, and orientation of elements within the image. Norihiko shows how to add motion to a character's face, background elements like an umbrella, and even how to apply different effects to create a dynamic and engaging scene. He also touches on the use of camera movements and zooms to enhance the video's storytelling.

In the final paragraph, the speaker reflects on the exciting potential of AI video generation tools like 'Raway G2' and the immersive experience of creating videos. He shares his personal enthusiasm for the process, noting how quickly time passes when working with these tools and the vast possibilities they offer for creative expression. Norihiko also mentions the increasing presence of AI-generated content on social media and encourages viewers to experiment with these tools. He concludes by inviting viewers who found the video interesting to like, subscribe, and look forward to the next video, emphasizing the fun and engaging nature of working with AI in video creation.
