How We Created an AI Video for Liberogic with Gemini Veo 3.1

  • column

The other day, our president asked me, "Hirocchi, could you make some kind of video with Gemini for the News section?"

To publish a New Year's greeting article, I tried generating an AI video with Gemini!

Without further ado, here is the finished video!

https://www.liberogic.jp/topics/20260101-news/

It has a New Year's feel, and the president's likeness is spot on, so not bad, right?
That said, creating this single video was quite a struggle.

Prompt: I want a New Year's greeting video for 2026. Use the president's face (photo attached) and make it an approximately 10-second video of the president speaking.

00:00 (背景に「ざわ...ざわ...」の文字。真ん中に社長。)

00:00 社長: みなさまさん、新年明けましておめでとうございます。

00:03 社長: 本年もどうぞよろしくお願い申し上げますね。

I asked for a New Year's-style background but didn't specify the greeting lines, so I realized I needed to write much more specific prompts.

After revising the prompt and making adjustments, I ran into the fact that Gemini only allows up to 3 video generations per day... Oh well, today's quota is already used up.

So it was decided that other staff members would make them too.

00:00 (社長のまわりにたくさんの従業員がいて手に飲み物を持っている)

00:01 社長: Happy New Year to everyone at Liberologic Corporation!

00:05 (従業員たちの拍手と乾杯)

Apparently the greeting came out in English.

Unless you specifically instruct it to "please respond in Japanese," it can cause things to go wrong in unexpected places.

00:01 社長: 新年明けましておめでとうございます。

00:04 社長: 今年もよろしくお願いしますの。

Personally, this is my favorite one.

"Thanks in advance for your help, I guess" (lol)

00:04 社長: 今年もよろしくお願いしますね。

This one was made by a senior colleague, but every time it generates, the forehead just keeps getting wider (lol).

Then came the request from the president: "Please get all the other staff members in there too."

The pattern where we load everyone's icon images so that people who look like company staff are standing around.

In the end, everyone hit the limit of 3 tries, unfortunately...

In the end, the video we published came together smoothly once we changed the order: generate the image first, then turn it into a video!

Prompt: I'd like a main visual image for our 2026 New Year's greeting. The president's face (attached photo morimoto_prof.jpg) should look like this, and the background should feel like a traditional Japanese New Year! The other attached illustration (group1.png) is a caricature of our staff, so I'd like them to appear around the edges to add some liveliness.

Prompt: Based on this image, please create a New Year's greeting video. I'd like a video of the president in the center saying, "Happy New Year. Thank you in advance for your continued support this year."

Finally, I got a video that looks good!

Getting the generation to work exactly as you want is quite difficult. Sometimes there's no audio, or the character speaks in English.

Breaking instructions down into fine, specific details also takes a certain amount of skill.

Why not try making an AI video yourself? It's fun!
