A bar spokesperson claimed the woman flew into a rage after being refused entry for "being too intoxicated".
The popular city centre venue said staff were unable to release her as they claim she was "spitting and biting".
She was later arrested on suspicion of assault by police shortly after 3.19am on Sunday.
A spokesperson for the Black Dog Ballroom said: "We are aware of the incident that happened in the early hours of 27th February, the footage you are referring to is of members of security restraining a female following a vicious attack on them.
"The full incident, which started due to a female being refused entry for being intoxicated was captured on CCTV.
"It involved a violent assault on a member of security team which left them with no option to restrain the female whilst they waited for the police to arrive.
"They were unable to release her because she was biting and spitting.
"When the police arrived they released the female unharmed. The police detained the female."
Greater Manchester Police confirmed that a woman, aged 29, was arrested on suspicion of assault but has since been bailed.
A spokesperson said: "We were called to a report that doormen had detained a female on Church Street at 3.19am on Sunday morning.
"A 29-year-old woman was arrested on suspicion of assault. She is on police bail."
