My video quality is poor

Poor video quality is normally due to a problem with the file or to bad encoding.

1 Make sure that the format of your video content matches the properties of the display

resolution, and that you’ve chosen the highest quality output possible. For example, if your

videos is 640x480 and you scale it to 1920x1080, this degrades the quality.

2 Since most video output modes are progressive, you need to encode video files as

progressive MPEG-2 files for the highest quality video reproduction. Otherwise you may see

video artifacts when the video is digitally interlaced on a progressive display.

3 Try re-encoding the video, or using a different application to encode the video.

4 (HD2000 only) Use interlaced video when outputting at 1080i.

My audio quality is poor

Poor audio quality is normally due to a problem with the file or to bad encoding.

1 Try re-encoding the audio or video, or using a different application to encode the video.

2 Open your video using Mpeg2VCR, and save it. (You can download a 30-day trial of

Mpeg2VCR from Womble.) Some videos have an uneven distribution of audio and video

packets in the MPEG stream. This can cause audio drop outs, hiccups, or distortion.

3 (HD2000 only) Use interlaced video when outputting at 1080i.

My video plays fine, but there's no audio

No audio is normally caused by the wrong audio codec.

(HD110, HD210, HD410, HD810, and HD1010 only)

Make sure the audio is MPEG-1 Layer II or

MPEG-1 Layer III. If you’re using AC3, it can be passed through over HDMI but not decoded

by BrightSign.

2 Make sure the video has an audio layer.

3 Try re-encoding the video, or using a different application to encode the video.

4 See General playback problems for more troubleshooting tips.
