- Encoding for Alcorn McBride Decoders |
|
Overview
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
(alcorn_mac.zip)
or the PC version (alcorn_pc.zip)
to obtain a demo of the Mac or PC encoder.
Mac Demo
The HDProQT Mac encoder is a HD Plug-In that will enable you to export
Alcorn McBride streams from any QuickTime supported application such
as Final Cut Pro, Premiere, After Effects, or the QuickTime Pro Player. Just
extract and run the Mac package installer from the .zip file. Now
the “PixelTools HD MPEG Demo” export option should appear
on all of your Export using QuickTime menus. Configuring the
options for your specific Alcorn McBride model as listed in the PtoolAlcornEncode.zip file
should enable you to produce an Alcorn McBride file on your first
export.
PC Demo
The
ExportHD encoder is a sophisticated stand-alone PC application that
encodes MOV and AVI files or sequences of TGA, BMP, or YUV frames. The
PtoolAlcornEncode.zip file contains configuration files used to customize
the encoder for your specific Alcorn McBride model and video content. Just
unzip the demo file in a folder of your choice, load the appropriate
ini configutation file as detailed in the PtoolAlcornEncode instructions,
select your video and audio sources, and depress the Run button.
Mac encoding
The PtoolAlcornEncode.zip file contains screen shots of typical encoding
configurations for each of the Alcorn McBride decoders when using the
HDProQT QuickTime Plug-In.

Note that the frame size of your
video content must be appropriate for your Alcorn McBride display. Running
the export process should create an Alcorn McBride stream. You
are welcome to further optimize the encode options. Detailed operation
of the encode options are listed in the HDProQT users manual.
PC encoding
The PtoolAlcornEncode.zip file contains ini files
for each Alcorn McBride product number and the most popular video formats. Select
the appropriate ini file in the Base Encoding Profile option in Expert-HD
or MPEGRepairHD PC encode applications.
