Pearl Nano User Guide Troubleshooting Quick Reference
Problem Action(s) to Resolve
There's an audible clicking noise in
recordings and live streams of my RTSP
video source
Remove the RTSP source using the Admin panel and recreate
it to resolve the issue.
Too much noise is present in the audio
output.
Check the input level of the audio source to make sure it's
the correct level. Modify the input
gain if necessary, see
Adjust audio gain and delay .
Video playback is fine, but when I play
the clip in Adobe Premiere Pro the
audio and video are out of sync.
Adobe Premiere Pro has a known issue handling video that is
recorded using a variable frame rate. Convert the clip to a
constant frame rate using a third-party software, such as
Handbrake, before editing in Adobe Premiere Pro.
Adobe Premiere Pro won't load my
.mp4 recording from Pearl Nano.
Check if the selected recording format in Pearl Nano is MP4-
Fragmented. Adobe Premiere Pro does not currently support
fragmented .mp4 files. Before editing in Adobe Premiere Pro,
convert the clip to progressive .mp4 format. Run the file
through ffmpeg or a third-party software such as Handbrake
to preserve both audio and video output.
Image quality is poor or insufficient.
The following tips can help improve image quality:
1. Ensure the source resolution is used as the output or
recorded resolution.
2. Increase the Bitrate value and/or decrease the Limit
frame rate value in the Encoding menu. See
Configure encoding .
Frames per second are lower than
expected.
The following tips can help improve frames per second (fps):
1. Increase the Limit frame rate value and/or decrease
the Bitrate value in the Encoding menu. See Configure
encoding .
2. Reduce the number of actions happening
simultaneously on the system (i.e. if streaming,
recording, and copying files, consider waiting to copy
files until after streaming and recording are complete).
3. Enter a low negative value (i.e. -5) in the Frame
Grabber's Vertical Shift field.
