Older compression formats like H.264 (AVC) lose significant visual clarity when compressed down to 300MB. Modern platforms rely heavily on H.265 (High Efficiency Video Coding) and the open-source AV1 codec. These advanced formats deliver up to 50% better data compression than H.264 while maintaining a surprisingly sharp 720p or entry-level 1080p visual resolution. Audio Optimization
