Eyeheight has added two aspect ratio converters to its product range.

The AR-2SD standard-definition and AR-2MD multi-definition converters enable 4:3 pictures to be converted between 16:9, 15:9 and 14:9 letterbox, 4:3 full frame and 2.35 or 1.85 anamorphic formats.

A flexible zoom mode allows source video to be compressed and expanded horizontally and vertically for unusual applications.

Both models, which also include digital noise reduction and allow direct connection to MPEG encoders, will be unveiled at NAB.
