Reducing the digital footprint of video files on Android devices involves decreasing the amount of storage space they occupy. This process typically involves adjustments to video resolution, bitrate, and frame rate, or employing efficient compression algorithms. For example, a video recorded at 1080p resolution and a high bitrate can be reduced in size by lowering the resolution to 720p and employing a more aggressive compression codec like H.265 (HEVC) instead of H.264 (AVC).
Lowering video file size is important for conserving storage space on devices, facilitating easier sharing via email or messaging applications with size limitations, and reducing data consumption when uploading to cloud storage services or social media platforms. Historically, methods for accomplishing this were cumbersome, requiring specialized software on desktop computers. Modern Android devices, however, offer various built-in functionalities and readily available applications for size reduction.
