Newly released cellphone video shows some of the last moments of passengers aboard the ferry that sank off the coast of South Korea last month.

In the video, one student is heard telling their parents "I love you." Others are alarmed by the tilting ship, while another person sings the theme of the movie "Titanic." Every now and then, a voice on a loudspeaker tells passengers to stay where they are. More than 300 people were killed or are presumed dead in the disaster.

The video was recovered from a cellphone recovered by the father of one of the victims. Most of the victims were students and teachers from a high school.
