Reducing the file size of video content destined for electronic mail transmission involves modifying its characteristics to minimize storage requirements. This is achieved through techniques such as compressing the video data, reducing its resolution, or lowering the frame rate. For example, a high-definition video recorded on a smartphone might be several hundred megabytes in size. Reducing its resolution to 720p and applying appropriate compression can decrease its size to under 25 megabytes, making it suitable for email attachments.
Transmitting large video files via email is often impractical due to sender and recipient mailbox size limitations and bandwidth constraints. Smaller video files reduce the time required for uploads and downloads, improving the user experience. Furthermore, minimizing video size conserves storage space on servers and client devices. Historically, the challenges of distributing video content via email have spurred the development of increasingly efficient compression algorithms and codecs.
