now movie streaming services are everywhere. there you will find various acronyms for film quality. Have you ever wondered what they really mean? here is the list.
if you ever see a movie where sometimes the audience suddenly appears in the movie, that’s the camera quality movie. a camera is a theatrical copy that is usually made with a digital video camera. sometimes they use a mini tripod, but many do it manually, so the camera shakes. and sometimes the location of the seats is not always inactive, it can be shot from an angle, some parts of the film cut off. the sound is taken directly from the camera’s built-in microphone, so you can sometimes hear the laughter of the audience quite frequently during the film. Due to these factors, the sound and picture quality is often very poor.
Actually, it is similar to the camera, but it is recorded under different conditions: it uses an external audio source (most likely an audio jack on the chair for the hearing impaired), but it does not guarantee good audio quality. Audio. and it is filmed in an empty theater or from the projection booth with a professional camera, giving a better image quality.
a telecine machine copies the film digitally from the reels. the sound and picture should be very good, but due to the equipment involved and cost, pull-ins are rare. usually the film will be in the correct aspect ratio, although 4:3 pulldowns have existed. sometimes shows a counter visible on the screen throughout the movie.
a prevhs tape, sent to rental shops and various other places for promotional use. the main drawback is a “ticker” (a scrolling message at the bottom of the screen, with the copyright and anti-copy phone number). furthermore, if the tape contains serial numbers or any other markings that could lead to the source of the tape, these should be blocked off, usually with a black mark on the section. this is sometimes only for a few seconds, but unfortunately on some prints it will last the entire movie, and some can be quite large. Depending on the equipment used, screen quality can range from excellent if made from a master copy, to very poor if made on an old VHS recorder via poor capture equipment on a copied tape. most screeners port to vcd, but there have been a few attempts at svcd, some look better than others.
same premise as a screen, but transferred from a dvd. usually letterboxed, but without the extras that a retail dvd would include. the ticker is usually not in the black bars and will break the display. if the ripper has any skills, a dvdscr should be very good. usually transfer to svcd or divx/xvid.
somewhat weird, a digital distribution copy (ddc) is basically the same as a screener, but it is sent/downloaded digitally (file share, ftp, http, etc) especially to companies like video clubs rather than to through a postal system. This makes distribution cheaper. its quality is lower than that of an r5, but higher than that of a camera copy or telesync.
for the last 6 months, major movie studios have been releasing retail dvd’s in russia. they do this to stop the widespread use of pirated pull-ins (once very common). lately though there have been very few actual pulldowns, most of the scene pulldowns you see are actually r5 retail. the main difference between pulldowns broadcast by pirates is that r5s are made with professional crews, professional studios and professional people. the quality of the r5 retail is very similar to that of the dvdscr, so time is not usually spent cleaning the dvdscr.
a copy of the final version on dvd or blu-ray dvd. if possible this is released before retail (eg star wars episode ii) again it should be excellent quality. dvdrips are released in svcd and divx/xvid or newer hevc codec formats.
As its name implies, tvrip is a source for capturing a television broadcast, mainly using an analog capture card (coaxial/composite/s-video connection). satellite digital copy (dsr, also called satrip or dth) is a copy captured from a non-standard definition digital source such as a satellite. hdtv means high definition television captured source, while pdtv (pure digital tv) means any copy of sdtv captured using only digital methods from the original transport stream, not hdmi or other outputs from a set-top box, can also refer to any definition standard content broadcast on a hd channel. DVB recordings often come from free broadcasts (such as digital terrestrial television). With an HDTV source, the quality can sometimes even exceed DVD. movies in this format are beginning to gain popularity. the main disadvantage is that some advertisements, commercial banners and subtitles in other languages can be seen on some releases during playback and cannot be disabled.
so the quality range we have now is like this. from high quality to low quality.
