How to Reduce Video File Size for Email & Sharing

Why Video Files Are So Large

Video files are large because they contain a sequence of images (frames) played back at 24 to 60 frames per second, along with audio data. A single minute of uncompressed 1080p video at 30 FPS would require roughly 10GB of storage, which is why video compression is essential.

Understanding Resolution and Bitrate

Resolution and bitrate are the two main levers for controlling video file size. Resolution refers to the number of pixels in each frame. Common resolutions include 4K (3840x2160), 1080p (1920x1080), 720p (1280x720), and 480p (854x480).

Choosing the Right Format

264 encoding is the most universally compatible video format. It plays on virtually every device and platform without requiring additional software. For sharing via email or messaging, MP4 should be your default choice.
