H264 vs M4V
Een uitgebreide vergelijking van H.264 Raw Stream en M4V Video (Apple) — bestandsgrootte, kwaliteit, compatibiliteit en welk formaat het beste past bij jouw workflow.
H.264 Raw Stream
Video FilesH.264 raw stream is an elementary bitstream containing only the video data encoded with the H.264/AVC codec without any container. It is commonly used as an intermediate format in video processing pipelines and for hardware encoder output.
Over H264-bestandenM4V Video (Apple)
Video FilesM4V is Apple MPEG-4 video format, similar to MP4 but may include DRM.
Over M4V-bestandenVergelijking van sterke punten
H264 Sterke punten
- Universal hardware decode on every device since ~2010.
- 40-50% smaller than MPEG-2 at equal quality.
- Mature ecosystem with dozens of encoders (x264 is the open-source gold standard).
- Every browser, phone, TV, and car infotainment supports H.264.
- Supports everything from 144p vertical phone video to 8K HDR masters.
M4V Sterke punten
- Fully MP4-compatible — one-line rename to .mp4 in most workflows.
- First-class support across Apple devices (macOS, iOS, tvOS, HomePod video).
- Supports chapters, closed captions, and multi-language audio tracks.
- Can hold Dolby Vision and HDR10+ metadata.
Beperkingen
H264 Beperkingen
- Patent-encumbered — encoding royalties apply for commercial use.
- 30-50% larger than H.265/AV1 at equivalent quality.
- Raw .h264 bytestreams have no timecode — containers (MP4/MKV) add that.
- High profiles decode slowly on pre-2010 hardware.
M4V Beperkingen
- FairPlay DRM variants tie files to Apple IDs — moves to other ecosystems break playback.
- Extension is not strictly standardized — some tools flag it as unknown.
- Rarely used outside Apple distribution.
