AVCHD is commonly used in camcorders and digital cameras, allowing for high-quality video capture while maintaining efficient file sizes. The format supports various resolutions, including 1080p and 720p, and uses the H.264 video compression codec. This makes it suitable for both consumer and professional use. AVCHD files can be played on compatible devices, such as Blu-ray players and media players, making it a versatile choice for video recording.
