Technical Structure and Codecs An MP4 container (.mp4) can hold video, audio, subtitles, and metadata. The file’s behavior depends on contained codecs (e.g., H.264/AVC, H.265/HEVC, AAC audio) and encoding settings: bitrate, resolution, frame rate, chroma subsampling, and keyframe interval. These parameters determine quality, file size, and compatibility. In professional workflows, creators select codecs to balance quality with storage/transmission constraints; for example, H.264 remains widely supported across platforms, while HEVC offers better compression at higher computational cost. A filename alone, however, does not reveal these details—inspecting the file’s metadata or using tools like MediaInfo is necessary to understand its technical profile.
