Rip
Digital extraction of content into another digital format
Most often we compress the original format and change its support.
Exemple : un DVD est compressé en AVI et va sur votre disque dur
BDRip
Copy of HD Blu-ray, often in .AVI or .MKV with various encodings (x264, Xvid, etc.).
BDrip quality is usually higher than DVDRip, but even though the source is in HD (Blu-Ray), BDRip is not encoded in HD. Its quality will vary depending on the file size, obviously the larger the file, the better the quality will be.
Just like DVDRip, we generally encounter two standard sizes: 700 MB and 1400 MB.
BDRip example (for reference):
Resolution: 720X384 | Encoding: XVid | Format: Avi | File size: 1400 MB
DVDRip
Copying DVDs, often in .AVI or .MKV with various encodings (x264, Xvid, etc.).
The resolution of a DVD is a maximum of 720 × 576 pixels, but the resolution of a DVDRip is often lower (e.g. 640 × 352)
The standard size of DVDRip was defined based on the capacity of CDs.
Most DVDRips are therefore 700MB, those of better quality 1400MB
DVDRip example (for information purposes only):
Resolution: 720X396 | Encoding: H.264 | Format: Avi | File size: 1400 MB
DVDRip / BDRip comparison
Tout comme le DVD tend à disparaitre au profit du BluRay, le DVDRip tend à disparaitre au profit du BDRip. Le BDRip est un encodage à partir d’un BluRay, bien que le BluRay ait au départ une résolution HD, la résolution du BDRip restera équivalente à celle d’un DVDRip, largeur de 720 pixels.
De même la taille du fichier encodé sera sensiblement la même à celle d’un DVDRip, 700 Mo pour un petit fichier ou 1400 Mo pour un plus grand.
For comparison, an HD encoding will have a width of 1280 pixels or 1980 pixels and will reach several GB (thousands of MB).
In the end, while image experts may see an improvement, for a DVD and a BluRay encoded with the same parameters, it will be difficult to see a difference between BDRip and DVDRip.
HDRip
Le format HDRip est un Rip (extraction vidéo) à partir d’une source en Haute Définition sans plus de précision.
Un cas particulier du HDRip est le BDRip copie de Blu-ray Haute définition, mais le HDRip peut aussi venir d’une source web par exemple (WebRip).
Although the video is extracted from an HD source, most of the time when the term HDRip is used alone, the created file will have standard resolution to be smaller.
HDRip movies will therefore often have a standard resolution close to 720 x 396 pixels.
Pour avoir un film en “Full HD” 1920 x 1080 pixels ou en HD simple 1280 × 720 pixels, il faut plutôt rechercher les termes 1080p ou 720p .
Even if the movie is compressed to a standard resolution, it is still worthwhile to extract video from an HD source to have the least imperfections in the original video.
TVRip
A video file recorded from a television. A common variant is SATRip, which refers to a recording from cable.
VHSRip
Rip from a VHS cassette, today we use this for videos that do not exist in digital format (on DVD or Blu-ray): old TV recordings or holiday films for example
In this case, we convert an analog source (VHS) into digital format (an .avi file for example)
Unlike other Rips which mainly need to have good software, in this case you need an acquisition device and a VCR.
WEBRip / WEB-DL
Video captured from an internet stream, most often from a VOD offer (Netflix, MyTF1, etc.), but also from other diverse and varied sources.
If there is no precision, the quality and resolution may vary (SD, HD).
Although the original streams are the same for WebRip and Web-DL, theoretically a Web-DL is directly downloaded without re-encoding, while a WebRip has been captured and then re-encoded. Often with WebRip you will see the presence of the original broadcaster's logo.
Web-DL is theoretically of better quality, but most of the time you won't see any difference with WebRip, some encoders mix the two terms.
An example to better understand the difference:
With some tools you can download YouTube videos by entering their address, these videos will be in Web-DL, because downloaded directly from YouTube.
If you take a screenshot instead of downloading video streams directly from the servers, it will be a WebRip.
BLURAY
720p
This means that the video will be in HD, with a resolution of 1280 × 720 pixels, fairly large file
1080p
This means that the video will be in HD (or full HD), with a resolution of 1920 × 1080 pixels, a very large file
HDLIGHT
HD video (720p or 1080p) is most often compressed using the X265 codec. Unlike the original videos, these videos are more compressed.
To watch them, you will therefore need less bandwidth and to store them on a hard drive, less storage space and they will be downloaded more quickly.
However, although these videos are in HD, this does not mean that they are always of excellent quality like a Blu-Ray, it will depend on the level of compression.
With a high compression level you will notice pixelation on certain images, less deep blacks for example.
With medium or low compression you will feel like you are watching a Blu-ray unless you get close to the screen.
3D
3D broadcast formats are all broadcast in HD. Most use Side-by-Side technology, with the left side of the screen reserved for the left eye and the right side for the right eye; some use Bottom-Top technology. To watch in 3D, you need a television equipped with this technology, preferably a device capable of playing movies in MKV format, or a Blu-ray player.
CAM (TS)
Pirate copy of a film using a camera (TS = Take on Screen)
HDTV
Recording on an HD TV channel
DVDSCR
Pirate copy of a promotional DVD
Similar to a DVDRip with a message warning that copying is prohibited
DVD-R
Full copy of the DVD. Unlike a DVDRip, you can find menus in several languages and subtitles.
On the other hand, the file is larger
