  1. questionCompatiblity issues with certain SanDisk CompactFlash cards
    We have recently been notified of issues with certain SanDisk CompactFlash cards.The cards that have issues are labeled "Ultra" cards and have a gray and orange label. These should not be confused with the "Ultra II" cards which have a black and red label. There are no known issues with the Ultr ...
  2. questionDo you make any video encoders?
    No. We design video and audio playback devices, not the encoders.We recommend using Main Concept Reference. It is an extremely versatile and inexpensive encoding software package. This software is capable of encoding video using various Standard-Definition(SD) and High-Definition(HD) video forma ...
  3. questionHow do I encode for the Digital Binloop or Digital Binloop HD using Main Concept?
    Main Concept Reference capable of encoding video using various Standard-Definition(SD) and High-Definition(HD) video formats, including the popular MPEG-2 and H.264 codecs used by Alcorn McBride's video products. Download Trial Here See our app note on encoding with this product here:http://www ...
  4. questionI'm replacing a DVM/HD with a DVM-8400. Will the same videos play in the DVM-8400 without conversion?
    Most likely. In addition to several other formats, the DVM-8400 plays MPEG2 Transport Streams (just like the DVM/HD). There are only two cases where the files would not play as expected. First, the bitrate of the videos must not exceed 40Mbps. The DVM/HD supported a maximum bitrate of 50Mbps, so ...
  5. questionIs there a limit to how large my video files can be to play in the Binloop HD/Digital Video Machine HD (Model 8400HD)?
    Yes, and no. The Binloop HD reproducers/DV8400HD use the FAT32 file system, which has a maximum file size of 4GB. This means you cannot directly play a file larger than 4GB in the Binloop HD/DVM8400HD. However, you can divide this file into several 'chunks' using a file splitting program. As lon ...
  6. questionMPEG Video Encoding Parameters
    Below are encoding parameters for High-Definition and Standard-Definition bitstreams. DVMHD Encoding Parameters (High-Definition) MPEG2 files must be encoded as a Transport Stream. Elementary Video stream must be Main Profile High Level MP@HL 4:2:0. Elementary Audio Stream is required and mu ...
  7. questionWhat is WMVHD and how can I encode for it?
    WMVHD is a Hi-Def video format created by Microsoft. The Information Station HD supports all the 1080p and 720 formats of WMVHD. There's some good general information on WMVHD here: http://www.wmvhd.com/ Some more information on how to make files can be found here: http://www.microsoft.com/windo ...
  8. questionWhat software packages are available for encoding MPEG-2 video?
    There are many packages available that can be used to encode MPEG-2 video. The simple answer is that you need a package capable of creating an MPEG-2 Program Stream from whatever source you can provide. Some examples of sources might be an uncompressed AVI or Quicktime video. A Program Stream co ...
  9. questionWhat types of video files does the Digital Binloop HD/Digital Video Machine (Model 8400HD) play?
    It will play video elementary streams that are encoded with MPEG2, H.264, or VC-1. It will also play Transport Streams that contain 1 of those 3 video types, as well as an MPEG, AAC, or AC3 audio track. It WILL NOT play Program Streams, Quicktime MOV, WMV, MP4, M4V or AVC multiplexed files. See ...
  10. questionWhere can I get my MPEG-2 or WMV/HD video encoded?
    Lots of places. Some approved encoding services may be found in our listing at: http://alcorn.com/library/appnotes/EncodingServices/index.html. If you'd like to be added to the list or recommend someone, let us know by writing to: support@alcorn.comIf you like to try encoding your video yourself ...
  11. questionWhy is my video glitching and/or drifting out of sync with the audio?
    In the Binloop, the audio sample rate of the video file AND the Binloop must match. If they do not, audio does not play at the correct rate. This results in a severe loss of A/V sync, and possibility glitching in the video. The solution is to configure the Binloop to the same sample rate as the ...
  12. questionWill this product play Standard Definition video files?
    Yes. However, it will not play Program Streams. The SD video must be encoded as an elementary stream or a transport stream.
