The men stole money from the TSB bank on Dunearn Drive on 29 January before escaping on bicycles.
The six-minute film shows them pointing what appears to be a handgun at staff before filling green bags with cash.
Officers have appealed for information about the two men, at least one of whom is believed to be Eastern European.
Staff were threatened by the men with the gun and a crowbar, which can also be seen in the footage. No-one was injured in the raid.
After leaving the bank at about 10:40, the two men cycled off along Alford Avenue and were spotted a short time later on Cawdor Crescent.
Both were white, roughly 30 years old and were wearing dark-coloured baseball caps.
One suspect, who was about 5ft 9in (1.75m) tall, was wearing dark blue jogging bottoms with a distinctive white logo, which police have established is that of Mordex, a Polish brand associated with bodybuilding.
Det Insp Colin Robson, who is leading the investigation, said he hoped the footage could jog the memory of people in the area.
He said: "I can reassure the local community that we're working tirelessly to track down these men and will exhaust all avenues of inquiry.
"While the answer to their identity remains unknown, it may lie in the local community and I would urge anyone who views this footage, which is being shared nationally, and who recognises them or their description to contact police immediately."

The waste, which includes soft toys, plastic bags and photographs, was discovered by the charity that operates Telford Steam Railway.
The site - owned by Network Rail - is near the A4169 near Horsehay, the Shropshire Star reports.
Network Rail said it was supporting an investigation by West Mercia Police to identify the culprits.

Network Rail said it had been monitoring the site to find out who was responsible for the fly-tipping.
Simon Masters, media relations manager, said: "Fly-tipping causes a great amount of misery to those who live nearby, as well as costing the taxpayer tens of thousands of pounds in clean-up costs."
Paul Hughes, from Telford Steam Railway, a group which leases a signal box on the site, said he first discovered the dump before Christmas.
"We were doing a routine inspection when we discovered there was some commercial fly-tipping which progressively increased to what has become a huge mountain of waste," he said.
"We are all used to seeing somebody drop off an old sofa or bedspread but this is on a completely different scale."
Telford and Wrekin Council said it was working with the police and the Environment Agency.

Offenders forced their way into a house on Bower Street, Carlisle, early on Saturday evening, Cumbria Police said.
A 39-year-old man was taken to hospital with a serious head injury. A woman, also 39, had her finger broken.

The injured man remains in hospital.

Its survey of manufacturers, retailers and the services sector showed a balance of 6% reporting increased business, the lowest since May 2013.
The economy has had a "tough start to the year", said Rain Newton-Smith, the CBI's director of economics.
Official figures last week put UK growth at 0.5% in the last quarter of 2015, the slowest for three years.
Ms Newton-Smith said: "Manufacturing and business and professional services have struggled to make a mark, but a healthier picture can be seen in the household-focused consumer services and retail sectors."
Output from professional services firms - including telecoms, computing and legal services - slowed down the most, according to the CBI Growth Indicator.
The CBI figures signalled only "modest" growth in the next three months.
Reports have suggested the Bank of England will this week cut its UK economic growth forecasts to around 2.3% for 2016, compared with 2.5% in November.
The central bank will release its latest inflation report on Thursday, when it will also keep interest rates unchanged amid concerns about global economic volatility.
A Treasury spokesperson said: "Despite turbulence in the global economy, Britain is pushing ahead and continues to grow steadily."
Police have released the full CCTV film from a Kirkcaldy bank which was held up by two armed men in January.
