## Guides (ES)

- [Sincroniza tu FIT con tu video](https://override-studio.pages.dev/es/guias/sincronizar-fit-con-video/index.md): La sincronía es el corazón del overlay: cada frame debe mostrar el dato del segundo exacto. override.studio propone un offset automático y te deja afinarlo a mano.
- [Pon potencia, FC, velocidad y GPS sobre tu video](https://override-studio.pages.dev/es/guias/overlay-potencia-fc-velocidad-gps/index.md): Los widgets leen tu FIT segundo a segundo y se dibujan sobre cada frame al renderizar. Elige una plantilla lista o construye la tuya.
- [Renderiza y exporta tu video con telemetría](https://override-studio.pages.dev/es/guias/exportar-video-telemetria/index.md): El render dibuja los widgets sobre cada frame y produce un MP4 listo para compartir. Todo ocurre en tu navegador.
- [Trae tu telemetría desde Intervals.icu](https://override-studio.pages.dev/es/guias/intervals-icu-como-fuente/index.md): Si tus actividades viven en Intervals.icu, no necesitas descargar .FIT: conecta tu clave API personal y elige la actividad dentro de la app.
- [Alternativas a Dashware y VIRB Edit](https://override-studio.pages.dev/es/guias/alternativas-dashware-virb-edit/index.md): Los dos gigantes gratuitos del overlay de telemetría dejaron de desarrollarse. Esto es lo que queda en pie —de pago, gratis y open source— y para quién es cada opción.

## Guides (EN)

- [Sync your FIT with your video](https://override-studio.pages.dev/en/guides/sync-fit-with-video/index.md): Sync is the heart of the overlay: every frame must show the data of the exact second. override.studio proposes an automatic offset and lets you fine-tune it by hand.
- [Put power, HR, speed and GPS on your video](https://override-studio.pages.dev/en/guides/power-hr-speed-gps-overlay/index.md): Widgets read your FIT second by second and draw over every frame at render. Pick a ready template or build your own.
- [Render and export your video with telemetry](https://override-studio.pages.dev/en/guides/export-video-with-telemetry/index.md): Rendering draws the widgets over every frame and produces an MP4 ready to share. It all happens in your browser.
- [Pull your telemetry from Intervals.icu](https://override-studio.pages.dev/en/guides/intervals-icu-as-source/index.md): If your activities live in Intervals.icu, skip downloading .FIT files: connect your personal API key and pick the activity inside the app.
- [Dashware & VIRB Edit alternatives](https://override-studio.pages.dev/en/guides/dashware-virb-edit-alternatives/index.md): The two free giants of telemetry overlay stopped development. Here is what is left standing —paid, free and open source— and who each option fits.

## App

- [Open the app](https://override-studio.pages.dev/): the editor itself (needs Chrome/Edge with WebCodecs).
