When skipping between files on a single track I hear pops and squeaks in the audio.
Make sure that all sound files played to a track have identical encoding parameters (i.e. bitrate, sample frequency, encoding format, etc.).
How do I make MPEG-2 files for my Digital Video Machine?
The most important step in creating video for your application is to perform the highest quality MPEG encoding of your source material.
Encoding professional-quality MPEG material is more ...
Why does my DVM2 lose audio/video sync over time?
Your audio bitrate may be 192Kbps. There is a known issue with 192Kbps audio that causes cumulative A/V sync loss. You can either re-encode the stream at another bitrate (e.g. 224Kbps) or use a se ...
Videos that individay play correctly on the DVM2 dont play sequentially.
The type of encoding may be different from one video file to the next. Because playlists default to seamless operation, the DVM2 will not stop decoding the video stream between files. If encoding ...
My DVM2 plays audio and video out of sync and the output is jerky.
There are two common causes for this problem. First, you may be playing your material at the wrong sample rate. Our test material contains audio with 44.1KHz sample rates. The DVM2 uses the lowes ...
What's wrong when a clip just plays a second and then freezes?
It's probably an encoding problem. If using Discreets Cleaner 6.0, activate the progressive field rendering tab.
The customer who discovered this used PixelTool's MPEG Repair to analyze his clip ...
Video files on my DVM/HD play correctly when played alone, but not in a playlist. Why?
The files must have identical encoding parameters to be played seamlessly. The DVM/HD defaults to 'seamless' mode when clips are placed sequentially in a playlist, concatenating the files during p ...
Can the DVMHD play 24p encoded material?
Yes. It will convert the 24p encodings to the specified format (1080i30, 720p60, etc.) during playback.
Please refer to the DVM/HD manual for a complete list of supported formats.
My 8TraXX responds very slowly to a Stop command. Why?
The sound file has a corrupted or missing sequence header. Try re-encoding the file. You can use a shareware program such as http://www.4musics.com/wav-mp3-wma-ogg-converter.htm

What bitrate should I use to encode MP3 files for the 8TraXX or MP3 Audio Machine?
The 8TraXX and MP3 Audio Machine are compatible with any MP3 file currently supported by the most popular (and some unpopular) software encoders available. The bit rate you should use primarily d ...
My 8TraXX or MP3AM responds slowly to serial or parallel play commands.
The 8TraXX and MP3 Audio Machine wait for an MP3 sequence header comes along in the currently playing file before transitioning to the next file. If your sequence headers are spaced too far apart ...

Do you make any video encoders?
No. We design video and audio playback devices, not the encoders, but you can find some information at http://www.alcorn.com/library/appnotes/encodingstandarddefvideo/index.html and http://www.alc ...
Where 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 ...
What 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 pr ...
MPEG 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.

What 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.w ...
