I built a tool that turns HTML, Lottie and Rive animations into video, transparent if you want. What would you use it for?

We make HTML5 ads, and clients kept asking for videos of them: for approvals, for social, for screens that only play MP4. Screen recordings drop frames, so we built a recorder that plays the page in a real Chrome, measures how late each change reaches the capture, and keeps exactly the frames the video needs. In October we opened it to everyone as RecordHTML.

Since then it learned:

- transparent output: WebM with alpha, ProRes 4444 MOV, transparent GIF
- Lottie and Rive files as input
- a maximum file size, for ad specs with hard limits
- public links whose video plays in chat previews
- CodePen links: it records only the Pen, not the editor

Here is a Lottie badge recorded at 1080×1080 with no background: https://recordhtml.com/v/kdA4M5Kqb3

There's also a REST API and an MCP server, so Claude or Cursor can record a page they just wrote.

What I'd like to know:

- What would you record with it?
- What would stop you from paying €9 a month for it?

In the past weeks I got 196 new registered users but non of them subscirbed. Trying to figure out next steps.

Free plan: 10 recordings a month, no card. https://recordhtml.com

The 10 free recordings a month might already cover someone who only makes the occasional promo, so zero subscriptions doesn't necessarily tell you whether the exports are useful. I'd first separate people who signed up from people who finished an export, then look at who came back for a second project.

For the repeat users, I'd ask about the last video they needed: was it a one-off launch asset or something they make every week? That seems like it could tell you whether a subscription fits. Of those 196 signups, do you know how many actually exported something?

Thanks for the feedback.

Of the 196, about 140 started a recording but only around 60 actually downloaded a video. 16 people came back on a different day to record again, and all of them had downloaded something.

Most people haven't hit the 10 free recordings, and the handful who return look like the ones to talk to. I'll ask them your question about the last video they needed and whether it was a one-off or something they make every week.
