The national board of the Screen Actors Guild voted Sunday to approve a two-year agreement covering film and TV projects by a slim 53 percent to 47 percent vote margin.

The proposed deal with the Alliance of Motion Picture and Television Producers includes a 3 percent annual wage increase and a 0.5 percent increase in the studio’s contribution to the union pension and health funds.

With the board’s approval, the agreement now must be ratified by the guild’s membership. Ballots will be mailed to eligible SAG members in early May, with results ready by the end of the month.

On the issue of Internet video, chief SAG negotiator John McGuire said the deal “tracks the new media provisions achieved by other entertainment industry unions.”

The 2007-2008 Writer’s Guild of America strike gave the writers a 0.36 percent royalty on downloaded video, a figure used in later studio AMPTP agreements with other unions.

The close board vote reflects a division within SAG between those who want to end the labor turmoil and those who insist that actors deserve a better deal. SAG National President Alan Rosenberg said he plans to oppose ratification. He voted against it in the board meeting Sunday.

If approved by SAG members, the agreement will conclude one of the longest labor negotiations in Hollywood history. Bargaining between SAG and the AMPTP began on April 15, 2008.
