Zespół Realizatorów Filmowych Rytm

Background
Zespół Realizatorów Filmowych „Rytm” (also known as Zespół Filmowy Rytm) was a Polish state-owned film company founded in 1955 and closed on April 30, 1968. It was involved in the production of feature films and was the so-called first generation team. The productions of this group were aimed at the cinema popular with the general public in the genres of comedy, musical, and crime fiction. The company's films are among the most popular classics of Polish cinema in the 1950s and 1960s. It was liquidated like several other Polish companies as a result of the so-called "March events" in 1968.

Technique: None.

Music/Sounds: A simple melody made with drumrolls and knock-knock-like sounds.

Logo: On a black background, a slightly angled light grey line draws in from the right side of the screen. As it curves and expands in size, "ZESPÓŁ" appears above and another line, in white, draws in at a higher plane and angled downwards. The white line then curves over, but in a shorter arc, and the grey line ends as an arrow, with "REALIZATORÓW" appearing above. A straight white line then draws in above the other two and then curves into one final arrow, overlapping the other two, as "FILMOWYCH" appears above it. Concentric white circles then appear in the bottom right corner and a line of arrows, pointing downward, draw in towards the center. As they reach the center, they start to repeat and the circles then animate like radiowaves, with "Times New Roman" appearing over them. Another line of arrows, this time going and pointing towards the left, wipe in and causes "PRZEDSTAWIA" to appear in a vertical format. The arrows and waves continue to slide about before the arrows turn transparent. They fade out, followed by the text, arrows, and circles.

Variant:
 * Two slightly different versions exist:
 * On  Birth Certificate , the rings are brighter and the arrows are absent, as well as "Times New Roman" being in a script font and in a horizontal manner. The said text also wipes in from left to right.
 * Another early variant exists which is essentially a shortened version of the standard variant, where the arrows remain completely still after they touch the "Times New Roman", along with the same horizontal "Times New Roman" appearing once the second set of arrows stop.
 * The logo has been colored on  Marysia i krasnoludki .

Technique: Cel animation.

Music/Sounds: Three whooshes when the arrows form, then a multitude of ominous synth noises after that.

Availability: Seen on few films from that time, including Birth Certificate, Marysia i krasnoludki and Głos z Tamtego Świata.
