15 terms
WEB-DL
A release-description term commonly used for a web-delivered source. It is a source claim, not a complete picture-quality measurement.
WEBRip
A web-source capture or re-encoding label. Encoding settings, source condition and resolution still matter.
Blu-ray / BRRip
Blu-ray names an optical video format; BRRip is used for an encode associated with a Blu-ray source. The labels do not specify every codec or track.
HDRip
A broad high-definition-source rip label. Do not read it as a guarantee of 4K resolution or HDR colour.
AVC / H.264 / x264
AVC and H.264 name the video coding standard. x264 is a software encoder for it. Compatibility depends on the actual encoded profile and device.
HEVC / H.265 / x265
HEVC and H.265 name a newer video coding standard; x265 is an encoder. Some older devices have limited support, even when the container opens.
MP4 / MKV
Containers for video, audio and other tracks. A container extension is not the same thing as a codec or a quality grade.
AAC
An audio coding format. The available channels, bitrate and supported playback device matter alongside the format name.
DD+ / E-AC-3
Dolby Digital Plus audio, also known as E-AC-3. A compatible player and output setup are needed for the chosen track.
Stereo / 5.1 / Atmos
Stereo and 5.1 describe channel arrangements; Atmos describes an immersive audio technology. The listening result depends on the full playback setup.
ESub / subtitles / captions
ESub commonly means English subtitles. Check whether the edition has selectable subtitles, text burned into the image or captions including sound cues.
Dual audio / multi audio
Descriptions indicating more than one audio track. Inspect the actual language list: the label does not identify which languages are included.
720p / 1080p / 4K
Resolution labels. Consumer 4K commonly means 3840 × 2160 pixels. Resolution alone does not describe bitrate, source quality or colour range.
HDR / SDR
High dynamic range and standard dynamic range are picture-presentation categories, separate from resolution. HDR needs compatible content and playback support.
CAM / Pre-DVD
CAM commonly indicates camera-captured material; Pre-DVD is an informal early-release label. Neither proves a particular source, language edition or quality level.
