01 / The short answer
The practical answer.
The output route from Paper.js depends on its source format and your installed edition. Record canvas playback or export rendered frames for video encoding. Vector artwork can animate smoothly while an imported screenshot remains resolution limited; plan the close-up accordingly.
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.
- Paper.js handles coded animation in this workflow. Implement an explicit scene clock, load the real assets, then render or capture a finite animation and encode it.
- Start with: The complete editable source, its assets and fonts, intended duration, output dimensions, frame rate, and audio if used.
02 / The walkthrough
The Paper.js walkthrough.
Build a small, complete sequence before expanding the film. The controls and delivery route below are specific to the tool.
Identify what you actually have.
Decide whether the source is an editable project, prototype, browser animation, image sequence, or already encoded movie. The complete editable source, its assets and fonts, intended duration, output dimensions, frame rate, and audio if used.
Prepare the source in Paper.js.
Set up a Paper project with a raster product image and independent vector accents. Fix the intended dimensions, duration, frame rate, fonts, and assets before rendering or recording the source.
Build the focal movement.
Use frame callbacks and path transforms for a focused underline or reveal that does not alter screenshot geometry. Test a short segment containing movement and text. If capture is required, hide the cursor and browser chrome and wait for assets to load.
Produce the delivery file.
Record canvas playback or export rendered frames for video encoding. Keep the source project and assets together so later changes do not depend on the compressed movie.
Review one complete playback.
Check the encoded file locally and at its hosted URL: duration, readable text, audio, video MIME type, and seeking must all work. Vector artwork can animate smoothly while an imported screenshot remains resolution limited; plan the close-up accordingly.
03 / Encoding example
Encode an existing recording or rendered movie.
If you already have a recording or rendered master, FFmpeg can encode a browser-friendly delivery file. This command does not render a project, prototype, or HTML animation.
ffmpeg -i input.mov -c:v libx264 -pix_fmt yuv420p -c:a aac -movflags +faststart product-launch.mp4
Install FFmpeg with the required encoders and replace the input path. Use a distinct output path. Capture or render at the intended dimensions and frame rate first; this command does not add missing audio.
04 / Worked examples
Three ways to apply it.
These are illustrative production briefs with tool-specific handoffs. They are not customer results, and the featured film above was made with LaunchVideoAI.
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 little tipIn Paper.js, begin with the source setup: Set up a Paper project with a raster product image and independent vector accents. Make the first product state legible before adding the transition.
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 little tipFor this sequence in Paper.js: Use frame callbacks and path transforms for a focused underline or reveal that does not alter screenshot geometry. Use the movement to connect the two product states, then leave a still interval for the result.
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.
A little tipTo finish this example from Paper.js: Record canvas playback or export rendered frames for video encoding. Review the closing label and CTA in the delivery file, not only the working preview.
05 / Checks and limits
Checks and limits before publishing.
Vector artwork can animate smoothly while an imported screenshot remains resolution limited; plan the close-up accordingly.
Delivery from Paper.js: Record canvas playback or export rendered frames for video encoding.
Keep the editable source, fonts, and approved assets. Confirm the rights to music and visuals, and check the available export options in the edition you actually use.
- 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.

01 / THE WORKFLOW
Work with Paper.js
- Set up a Paper project with a raster product image and independent vector accents.
- Use frame callbacks and path transforms for a focused underline or reveal that does not alter screenshot geometry.
- Record canvas playback or export rendered frames for video encoding.
- Vector artwork can animate smoothly while an imported screenshot remains resolution limited; plan the close-up accordingly.
02 / THE WORKFLOW
Start with LaunchVideoAI
- Enter your public product website URL.
- Choose the theme, video length, and anything you want to highlight.
- Generate an original product film with animation and music.
- Review saved versions, request changes, and download the finished 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.
What does Paper.js handle in this workflow?
Paper.js is used for coded animation. Implement an explicit scene clock, load the real assets, then render or capture a finite animation and encode it. Set up a Paper project with a raster product image and independent vector accents.
How do I get a finished video from Paper.js?
Record canvas playback or export rendered frames for video encoding. Vector artwork can animate smoothly while an imported screenshot remains resolution limited; plan the close-up accordingly.
Was the featured film made with Paper.js?
No. The featured film was made with LaunchVideoAI and is labeled accordingly. It is visual inspiration; the worked examples describe proposed production briefs.
You can use LaunchVideoAI to make an awesome launch video in a few minutes.
