Russian Central Studio of Documentary Films

Background
The Russian Central Studio of Documentary Films was a newsreel and documentary production company founded in 1927 originally as a division of Sovkino. The studio underwent several name changes throughout the 20th century, being Soyuzkinochronika from its founding year to 1931, All-Union Newsreel Factory from 1931 to 1936, the Moscow Newsreel Studio from 1936 to 1940, the Central Newsreel Studio from 1940 to 1944, the Central Studio for Documentary Films from 1944 to 1993, and lastly its current name since the latter year. During the 21st century, the studio was on the verge of bankruptcy before liquidating in 2015.

1st Logo (1944-1948)

Logo: The camera slowly backs away from a shooting line filled star with a outline and the Spasskaya Tower inside. Further away from the star, its large shadow is shown alongside a dark background in the same effect as the shape's fill. Once it stops zooming out, the company's full name in a serif font and with a shadow effect fades in below.

Technique: Cel animation and practical effects.

Music/Sounds: A cold chimes jingle repeated twice.

Music/Sounds Variant: There is a later arrangement of the normal soundtrack.

Availability: Very rare, due to many films released during the studio's first several decades going straight to the opening of the movie instead of a logo. The normal track can be seen on Москва — столица СССР while the rearranged score has, so far, appeared on На страже мира.

2nd Logo (1992)
Logo: Against a starry night background, the company name is displayed with the first letter of each word in and a different font than the rest.

Technique: None.

Music/Sounds: None.

Availability: Very rare, considering its short lifespan. It can be seen on Благовещение and Ветераны, ветераны....

Logo: A set of buildings (likely representing Moscow) are shown against a dark blue sky. On the top right is the company's full name in a nearly identical appearance as before.

Technique: None.

Music/Sounds: None.

Availability: Like before, it had a short lifespan, but there are slightly more films that have this logo. These include Светлое Христово Воскресение, Непобедимый никогда, and Милость к падшим.

4th Logo (1992-2005)
Logo: The screen zooms out of a simplistic coat of arms, consisting of a  double-headed eagle, the company's initials in  over the symbol, a long flag with two ends containing the Russian flag and "FILM STUDIO" in the center, the company's full name arced over the eagle, and "MOSCOW" arced below. The logo is shown against a sunburst background against a  foreground. Underneath the symbol, the company's full name in a stacked format wipes in.

Variants:
 * Starting in 1994, the company is referred to as "RUSSIAN CENTRAL STUDIO OF DOCUMENTARY FILMS".
 * The font for the text changed in 2002, becoming a bolded version of the original one.

Technique: Cel animation.

Music/Sounds: None or the opening theme of the film.

Availability: Uncommon. Many of their films can easily be found on archival sites such as Net-film and also have this logo intact on television airings. These include А нам нужна великая Россия, Отчего непрестанен ветер, and Герои-пасынки. The current name debuted on Ой, бог ты мой! and was later seen on Старый двор или Соло гитары с детским оркестром или Пой, Гриша. По следам Русского авангарда was the final film to use this logo.

Logo: Set on a gradient background, the following text is displayed: Федеральное агентство по культуре и кинематографии The text then fades out and in comes a close up of the logo from before. The seal zooms out while a still copy of it slowly fades out. Before the close up is gone from sight, the company's full name in a stacked format and Western-themed font, plus with "Russia" in normal capitalization, wipes in from top to bottom. The logo then disappears and is replaced with "ПРЕДСТАВЛЯЮТ ".

6th Logo (2010-2015)
Logo: There are multiple long filmstrips rising above against a dimly lit honey dew background. The screen zooms further above, passing by several more curvy filmstrips and black particles before the background becomes brighter and desaturated. When only a few dust particles are left within the background, a curvy and sleek Russian flag is seen over the company's initials in a metallic font, followed by their full name in a different font and small size.

Technique: 2D animation.

Music/Sounds: A peaceful, syntesized ambience note alongside some nature-like sound effects.
