Reducing the size of a video file for electronic transmission, specifically via email, involves encoding the video data using a more efficient compression algorithm. This process typically balances file size reduction with acceptable video quality. For instance, a video initially recorded in high resolution might be converted to a lower resolution and a different codec to achieve a smaller file size suitable for email attachments, which often have size limitations.
The ability to decrease video file sizes is crucial for efficient communication and collaboration. Historically, large file sizes posed significant challenges for sharing video content, requiring physical media or specialized file transfer services. Compressing videos enables quicker sending and receiving, reduced storage requirements, and decreased bandwidth consumption, all of which contribute to improved workflow and accessibility.
