What this tool does
The video trimmer exports a shorter MP4 from a selected start time and duration. It helps remove dead air, mistakes, countdowns, or unused endings before sharing or compressing.
Trimming before compression is often the cleanest way to reduce file size because it removes seconds instead of lowering quality across the whole clip.
Supported formats and output
- Input
- Browser-readable video files.
- Output
- MP4 containing the selected time range.
Practical examples
Remove a countdown
Start at 8 seconds and export only the useful demonstration.
Prepare a GIF
Trim a longer MP4 to a short segment before converting it to GIF.
Quality considerations
- Trimming protects quality better than over-compressing a long recording.
- If you also need a smaller file, trim first and compress second.
Limitations
- Very large sources can exceed browser memory.
- Exact cut placement can vary by codec and encoding behavior.
- This tool is for simple start-and-duration trims, not multi-clip editing.
Preguntas frecuentes
¿Puedo recortar archivos grandes?
La memoria del navegador es el límite. Empieza con clips cortos para mejores resultados y añade más adelante una opción en la nube para archivos muy grandes.
¿El recorte es exacto por fotograma?
Esta herramienta recodifica para compatibilidad, lo que permite recortes más precisos que una copia simple de flujo.
Troubleshooting
The trim starts a little differently than expected.
Try adjusting the start time by a small amount. Video keyframes and re-encoding can affect the visible first frame.
The export takes a long time.
Shorten the selected duration or try on a device with more available memory.
