The first regional chapter of the New York-based VideoTape Production Association has formed here to represent what the group's new president calls "Washington's sleeping giant," the postproduction videotaping industry.

The Washington-area videotape production market, which was virtually nonexistent 10 years ago, has grown to a $10 million business in the District alone, said Tom Angell, president of the new Mid-Atlantic Chapter.

Washington offers a variety of video jobs for postproduction companies, from political campaign videos and videotaped newsletters for trade associations to the shooting of documentaries for local television stations. All of these are a part of what Angell calls a "tremendously marketable" business in the Washington area.

Angell is president of Interface Video Systems, a Washington production house. He says he hopes the local chapter of the association can recruit the more than 200 companies in Pennsylvania, Maryland, Virginia and the District that are involved in electronic editing, audio, animation and computer special effects work -- which is done after the video has been shot.

The new chapter, which now has 20 members, plans to publish a book establishing industry standards and procedures for postproduction companies in an attempt to streamline videotaping efforts. The group also plans to offer a credit-checking service that would enable members to evaluate organizations that hire their services.

The new chapter also plans to offer forums so videotape production companies can meet with manufacturers to discuss new designs and improvements in equipment. TRADE

The Mid-Atlantic Food Dealers Association, a Baltimore-based trade group, has created a task force to identify the 1,000 Korean-owned grocery stores in the Baltimore-Washington region. "It appears that Koreans, more than any other ethnic group, have chosen their field of endeavor in the retail food industry," said William P. Miller, senior vice president of MAFDA. The group is headed by David Chu, who is the owner of Brentwood Food City IGA in Washington and marketing representative for B. Green & Co. Inc., a food wholesaler in Baltimore. Chu said Korean grocers need to know an organization such as MAFDA exists to represent their interests in the government and elsewhere. The association offers its 2,200 member companies insurance, educational and investment programs and a coupon clearing house, which charges a fee to process coupons and collect the refund money from manufacturers.

The Washington-based Association of Bank Holding Companies recently elected Kenneth L. Roberts, chairman of First American Corp. in Nashville, as its chairman, and reelected Donald L. Rogers as president. The group represents 180 bank holding companies, which own more than 1,700 subsidiary banks with $1.5 trillion in assets, a spokesman said. In the coming year, the group plans to continue to lobby for the passage of interstate banking laws and other regulatory issues affecting the industry, a company spokesman said.
