A Remotion Element should be a focused, reusable video building block that can be copied and remixed.
Start with a technique from a published video. Save its link and timestamp, then identify the reusable purpose—for example, emphasizing a phrase or introducing a speaker.
Web components, Remotion libraries, and AI-generated ideas may help with implementation, but they are not evidence that an idea works in a video. Create an original visual treatment; do not copy branding, footage, or proprietary assets.
An Element should represent one coherent visual treatment, technique, or workflow. It should work without configuration and be useful across projects.
The caption Elements show the distinction: moving a pill between words, popping words, and highlighting words all serve the same purpose but use distinct visual techniques that users would choose separately. Do not create Elements for arbitrary presets, minor CSS differences, or Studio-control configurations.
react, react-dom, and remotion. Every non-Remotion package must use an exact semantic version; version ranges and tags are not accepted. Remotion packages use version: null and are installed at the project's Remotion version.Size the Element to its smallest useful bounding box. By default, let the <Sequence> generated during installation control its placement and duration. Set both dimensions to null if it adapts to the composition.
An Element that already owns the one interactive Sequence users should edit may set installationMode: 'component-owned-sequence' in its central definition. In this mode, the public component must accept and forward from, durationInFrames, name, and style to its Sequence and rendered outline. It must also define its own rendered dimensions because Element metadata dimensions are not passed as component props.
Do not use the component-owned mode merely to remove markup: The Element needs to remain movable and trimmable through its component-owned Sequence. Do not add internal padding only to improve the gallery preview.
If an Element is intended to appear temporarily over other content—such as an overlay, lower third, label, or callout—include both an entrance and an exit animation.
Backgrounds, loops, full-scene treatments, and other Elements that are not expected to enter and leave independently do not need these animations.
Animate properties within the Element, such as translation, scale, and opacity; leave placement to the generated wrapper or the component-owned Sequence.
Use Studio controls in the Element's Interactive schema, not React props on its public component, for user-facing customization. Expose only controls that meaningfully edit the treatment; they may tune details but must not switch between unrelated visual styles.
Give editable objects clear names, using a generic name such as Container for the main object and child controls only for separate editing targets.
Follow the interactivity best practices.
Choose a poster frame that clearly shows the Element. The video preview should cover the Element's full duration and, when applicable, include its entrance and exit animations.
When ready, submit the Element.
