The video, taken from coastguard boats and helicopters, showed the last moments of the 6,825-tonne Sewol ferry as it listed and then capsized on April 16 with the loss of around 300 lives.
Among the dead were some 250 students from the same high school in Ansan city just south of Seoul.
Dozens of family members were in the courtroom in the southern city of Gwangju and many wept openly at the scenes of passengers desperately trying to escape the ship.
Captain Lee Joon-Seok and three senior crew members are accused of "homicide through wilful negligence" -- a charge that can carry the death penalty.

The 11 other crew are being tried on lesser violations of maritime law.
The bulk of the charges arise from the fact that Lee and the others chose to abandon the ferry while hundreds of people were still trapped inside.
They were also condemned for ordering the passengers to remain where they were when the ship began listing.
In particular they noted the location of many student victims who, on the order of the crew, had remained in their cabins on the fourth level.
"With timely evacuation efforts, these students could have fled through these exits," one prosecutor said, pointing to the model.
"But almost all of them waited in their cabins and died. We will make it clear that this result was caused by the behaviour of the defendants," he said.
Lee and his crew were publicly vilified in the wake of the tragedy, and there been some expressions of concern about how fair their trial can be with emotions still running so high.
