WebM + VP9: Currently the most widely supported transparent video format, compatible with Chrome, Firefox, and Edge
Video Encoding: Requires encoders that support alpha channels, such as VP9
Canvas Processing: Can process video frame by frame for more complex transparency effects and interactions
CSS Blend Modes: While not true transparency, can achieve visual overlay effects
Alternative Solutions: For browsers that don't support WebM, consider using APNG or GIF, but with lower quality

Note: Transparent background videos require specific video formats and encoding methods. Regular video formats do not support alpha channels.
