A file is only "better" if the codec inside (like HEVC or AV1) is more modern than the standard AVC. You can check the internal details of any video file using tools like the VLC Media Player's Codec Information tool. 4. Compatibility Trade-offs

Newer formats are better optimized for 4K and 8K streaming, maintaining sharpness that older MP4 profiles might lose during compression. 3. Container vs. Codec: The "Better" Distinction

It is critical to distinguish between the (the .mp4 wrapper) and the codec (the actual video data).

Advanced codecs can deliver the same visual quality as H.264 at roughly half the bitrate.

Standard MP4 files often use the H.264 (AVC) codec. Newer or custom configurations (like those potentially used in a "sone385" variant) may leverage H.265 (HEVC) or VP9.
