Video Formats
The reproducers in the Digital Binloop HD support a variety of
different video formats including MPEG-2, H.264, and VC-1. As
discussed previously in this section, these formats can be
encoded as Video Elementary stream files (
m2v , h264 , or vc1 )
or within Transport Stream files ( mpg ).
MPEG-2 Video Specifications
The decoder within each reproducer is compliant with Main
Profile/High Level MPEG-2 specified in ISO/IEC 11172-2 and
ISO/IEC 13818-2. The following table summarizes the
recommended encoding parameters for creating MPEG-2 video
that is compatible with the Binloop. Keep in mind that MPEG-2
video can be encoded for the Binloop HD in one of two different
forms. You can encode it as an MPEG-2 Video Elementary
Stream (like VID00001.M2V), or you can encode it within an
MPEG Transport Stream (like VID00001.MPG).

* Both Constant (CBR) and Variable (VBR) bitrate are supported,
so long as the bitrate does not exceed the maximum.
** Although the Binloop HD supports playback of 1080p24,
1080p25 and 1080p30 files, it does not support playback of
1080p60 files.
*** The Binloop HD will perform framerate conversions based on
the Video Output format for which it has been configured.
However, in some cases this conversion is very difficult and may
result in unsatisfactory playback. For example, playing a 24fps
file on a 29.97fps output will work nicely. However, playing a
25fps (PAL) video on a 29.97fps(NTSC) output usually produces
undesirable results. Keep this in mind when configuring the
Binloop HD’s video outputs and encoding content.
