01 / The short answer
The practical answer.
Claude can provide animation source or an HTML design, but those exports are not automatically video. To make an MP4, first render frames or record the animation, then encode and verify the result.
MP4 is a container, not an animation project. A broadly compatible delivery choice is H.264 video with AAC audio when sound is included. Keep frame size, frame rate, and duration consistent through rendering and encoding. Do not rename an HTML, ZIP, GIF, or WebM file to .mp4 and expect it to become a different format.
- The complete editable source, its assets and fonts, intended duration, output dimensions, frame rate, and audio if used.
02 / The walkthrough
The Claude walkthrough.
Make one clear first version, review it, then refine the details.
Export a complete, finite animation.
Use the available export controls to obtain the source and assets. Ask for a local version with a fixed duration and restart behavior. Open it outside Claude and confirm that it does not rely on missing files or a signed-in session.
Choose recording or frame rendering.
For a quick draft, capture the local animation at the intended size with a screen recorder and exclude browser chrome. For repeatable production, use a renderer that can seek the animation to a specific time and capture frames. An interactive page with uncontrolled timers needs preparation first.
Check fonts, assets, and timing.
Wait for images and fonts before starting capture. Disable unrelated UI and notifications. Verify the first and final states and avoid an extra loop at the end. If audio is separate, plan when it starts and how it ends.
Encode the captured material.
If the recorder produces a compatible MP4, inspect it directly. Otherwise encode the recording or rendered frames with a video tool such as FFmpeg. Changing a filename extension is not encoding, and an HTML or ZIP file cannot be passed off as a video.
Verify local playback and hosted delivery.
Watch the full file in a separate player and a browser. Check duration, text, and sound. If local playback works but the hosted player fails, inspect the actual response type and access rules rather than regenerating the animation immediately.
03 / Encoding example
Convert a captured recording.
After recording the animation, this example encodes an existing WebM recording as an H.264 MP4. It does not render HTML; FFmpeg must already be installed with the required encoders.
ffmpeg -i recording.webm -c:v libx264 -pix_fmt yuv420p -c:a aac -movflags +faststart product-launch.mp4
Replace the input and output filenames. Preserve the intended dimensions and frame rate at capture. If the recording has no audio, this command does not add a soundtrack.
04 / Worked examples
Three ways to apply it.
These are illustrative production briefs. They are not customer case studies or claims that the featured tool produced the LaunchVideoAI film above.
A 15-second logo and feature reveal
Use a 1920 × 1080, 30 fps target as a concrete test: 15 seconds corresponds to 450 output frames. Verify the reveal, the still hold, and the closing frame. Choose a simple domain-based filename such as acme-feature-reveal-v1.mp4. The test catches a common mistake: a preview that loops indefinitely even though the intended video should end.
A screenshot demo with a separate music track
Render or record the full demo, then confirm that the music starts at the intended point and ends cleanly. Listen to the exported file rather than trusting the editor preview. If the source recording has no sound, adding an audio codec option alone will not create a music track; the audio must actually be included in the export or encoding stage.
A revised version for a different destination
Keep version one intact and export a new file after changing the closing CTA. Recheck crop, font size, and final duration rather than assuming only the words changed. Use filenames such as acme-launch-v2-landscape.mp4. If you change the aspect ratio, recompose the scenes; stretching the old export usually damages text and screenshots.
05 / Checks and limits
Before you publish.
An artifact can help you iterate on source and layout. An HTML export still needs rendering or recording for MP4 delivery. Check local assets, fonts, and timing before capture.
- Open the file in a separate player and in the browser where it will be used.
- Check the first and last frame, the full duration, and audio sync.
- Keep the editable project and original assets separately from the delivery MP4.
- A standard H.264 MP4 does not preserve transparency; choose a background or a different delivery format.
06 / A website-first option
Choose the production path.
Use Claude when its workflow fits your project. For an original product film based on a public website, LaunchVideoAI offers another starting point.
01 / THE WORKFLOW
Work with Claude
- Use the Claude walkthrough for this specific task
- Supply accurate product facts and publishable assets
- Review the scene plan and produce or export the film
- Keep the editable source and verify the delivery file
02 / THE WORKFLOW
Start with LaunchVideoAI
- Enter a public website URL
- Choose the theme, length, and anything to highlight
- Generate original animation and music for the product
- Review versions, request an edit, and download the MP4
YOUR WEBSITE IS ALREADY THE BRIEF
Let’s put it in motion.
Original animation and music, made for your brand.
07 / Common questions
Questions before you start.
Why does an MP4 still fail to play in a browser?
The extension alone does not prove that the file contains a supported codec. Check the encoded video and audio, then check delivery headers, access permissions, and byte-range support. A correctly encoded local file can still fail if its hosted URL returns an error page instead of video.
Is an HTML artifact already a video file?
An artifact can help you iterate on source and layout. An HTML export still needs rendering or recording for MP4 delivery. Check local assets, fonts, and timing before capture.
Was the Revolut example made with Claude?
No. The featured Revolut film was made with LaunchVideoAI. It is product-video inspiration, not a result from this Claude walkthrough. The worked examples are proposed briefs, not demonstrations of measured customer results.
Can I start from my public product website?
Yes. LaunchVideoAI starts from a public website URL. Choose your theme, video length, and focus, then review the generated film and request changes if needed. Check the current Essential and Explore packages before purchasing.
You can use LaunchVideoAI to make an awesome launch video in a few minutes.
