The British cruise ship famously hit the North Atlantic Ocean seabed in the early hours of April 15, 1912.
The clip shows the cabins and hallways where passengers slept, ate and partied on their journey from Southampton to New York.
It also reveals cooking utensils, bottles and cutlery, in a room where it is likely chef's prepared meals for their wealthy passengers.
Another angle displays the sheer size of the vessel – which remains a shipwreck near the Canadian island of Newfoundland.
HAUNTING: The video shows Titanic 100 years on
The clip was originally posted on YouTube on July 27 2010, but has gained popularity again after being shared on Reddit.
Users were remembering the tragic event that saw more than 1,500 people lose their lives more than 100 years ago.
One comment read: "I think it's weird how one second the Titanic was this magnificent, booming ship with people drinking expensive wines and using china and now it's just this abandoned piece of machinery at the bottom of the ocean."
Another added: "The bottles of wine, plates and shoes are still intact. So sad their life had to end so tragically."
Before a third simply stated: "Elegant yet so creepy. This ship will always remain a magical mystery."
Forgotten shipwrecks of the Atlantic
These are the forgotten shipwrecks of the Atlantic Ocean dating back to the First World War. The liners were sunk by torpedoes and mines and now lie on the seabed, just off the Irish coast. Among the wrecks are merchant vessels, submarines and ocean liners, with HMS Audacious being the oldest ruinCaters News Agency Among the wrecks are merchant vessels, submarines and ocean liners, with HMS Audacious being the oldest ruin
Although Titanic had advanced safety features such as watertight compartments and remotely activated doors, it only carried enough lifeboats for 1,178 people — about half on board.
A high number of men were left aboard the sinking ship as a "women and children first" protocol was implemented.
At 2:20am, she broke apart and foundered with well over one thousand people still aboard.
Just under two hours after Titanic sank, the Cunard liner RMS Carpathia arrived and brought aboard an estimated 705 survivors.
