Although I don't work on it every day, I've been working on a project to roughly create a book in 3D and generate videos promoting it. While aiming for 100% compatibility with Capcut, the list of things to do kept growing, so I ended up using remotion or gasp to maintain video effects and create identical text animation effects.
At first, I created a tool identical to Capcut, but this time I made it specifically for publishers to promote books.

When exporting, it exports in various formats such as After Effects, Final Cut, Premiere XML.

The AI-generated interface is just right for my needs, not too much or too little. ^^;
On the left, it has the same timeline layout as Capcut. The book is also made transparent and saved as a sequence of images to be reused as footage.
In After Effects and Final Cut, the book comes in as an actual 3D OBJ. I'm planning to upload daily book sales rankings and other data, binding it to the video generation process.
I'm also using free Capcut stickers for my work. Sometimes a video gets uploaded to Shorts and immediately reaches 6,000 views, which makes me wonder if that's all there is to it. Lately, I've been thinking about what I'm even doing by making these boring videos. ^^
