Tech Tips - Encoding for Alcorn McBride Decoders


PixelTools HD MPEG encoders are an optimal solution for encoding your high definition video content into studio/museum quality Alcorn McBride ATSC streams. The encoder’s precise patent pending spatial and color computations highlight the wow factor of Alcorn McBride’s media server especially in cinema sized environments. Specialized museum and outdoor display requirements like seamless clip looping and extreme aspect ratios are easily handled in the encoders.

This tech tip will guide you in the encoding for each of the Alcorn McBride models to enable you to create a playable stream on your first encode.

Demo of Alcorn McBride Encoding

Download the Mac verison ( or the PC version ( to obtain a demo of the Mac or PC encoder.
