The video has been released in a bid to trace the two men following the incident that took place in Birmingham on July 31.
The woman, 34, from Wolverhampton, was raped on parkland at the back of Moor Street train station.
She had been at Chameleon Bar in Hill Street on the evening of Friday, July 31. When she left the bar alone she asked for directions to the train station and a man offered to help her.
She was led across Birmingham to an area at the back of Moor Street before being raped.
Detectives investigating hope people will come forward with information to help identify the pair.
After the attack the men got on the 97a bus to Bordesley Green at Park Street by Hotel la Tour. They got off the bus at Bordesley Green at the junction with Third Avenue.
The men are described as black, between 20 and 25 years old. One has short afro hair and was wearing a black shirt, black trousers and black shoes with distinctive white soles.
The other man was wearing a dark blue baseball cap, white and blue checked shirt, blue jeans and white trainers.
From CCTV examination detectives know that the woman may have been unsteady on her feet at times and was being held up by the man featured in the footage.
DC Steve Jones, from West Midlands Police Public Protection Unit, said: "From the footage we can see the woman being led away by one man and a second man walks a number of paces behind.
"We believe the two men are both involved in this attack. We know they walked up Hill Street shortly after the woman to Victoria Square before one approaches her while the other hangs back.
"We are supporting the woman throughout the investigation."
