MP4 is a container, not a quality guarantee. A well-encoded stream beats a bloated file with a fancy extension.
Focus on official sources and stable playback instead of chasing acronyms.
Containers can hold different codecs. Two MP4s can look different if the bitrate differs.
Trust your eyes and ears, not only the filename.
Higher bitrate needs more bandwidth. Match settings to your network.
If motion smears, lower quality or reduce motion enhancement on TVs.
Stereo is fine for phones; surround matters in living rooms.
Check audio sync if dialogue feels off.
Licensed platforms encode carefully. Random uploads may mislabel quality.
