Not sure if this has been covered before, but if not it may help those who have been a: complaining about quality and b: determine what movies they want to download.
Here is a brief definition of the terms describing the movie qualities. Some are rather straight forward, some are not
Top being highest quality down to the lowest quality at the bottom.
1.BLURAY also referred to as BD, BDRIP, or Blu-ray
These high definition optical discs obviously make for the best possible video source, but are seldom used due to their immense file sizes being inefficient for streaming.
Video source taken from an original retail DVD, with no notices displayed during playback. It is common for DVD screeners to be mislabelled as DVD rips.
3. DVD-SCREENER also referred to as DVDscr or Screener
Screeners are sent out by movie studios to retailers, film critics, and other places for promotional use or award consideration. They are of the highest video quality, but usually letterbox format. You’ll see an anti-piracy ticker scroll across the screen every so often.
4. TC or TELECINE; sometimes called R5
High quality releases are made possible by digitally copying the film reel from the movie theatre, not very common due to the expensive equipment involved.
5. TS or TELESYNC
Pretty much a good quality CAM release, except an external audio source (such as the theatre’s hearing impared jack) is used. They are sometimes filmed in an empty cinema or from the projection booth, with a tripod for steady image. Quality can vary from exceptionally high to very poor. Worth trying out if you’re really excited about watching something new.
This type of release is the lowest quality and most people don’t even bother watching them. It is filmed from within the cinema with a portable digital camcorder. It is common to hear people laughing in the background or see someone’s body walk across the screen.
