What is PNXSERVR.exe?

The genuine PNXSERVR.exe file is a software component of ProCode Nexus Server by Thomson Multimedia.
The PNXSERVR process is the core transcoding engine of the Nexus Server, part of the ProCode video format converter tool originally developed by Canopus Corporation. It provides the ability to convert audio and video files from one encoding format to another so that files can be played back on a wider range of equipment. Founded in 1983 in Kobe, Japan, Canopus established a reputation in 3D graphics cards, especially in the gaming world, with its Pure3D card having 50% more memory (6MB) than the standard cards (4MB). They were acquired in 2005 by Thomson Multimedia to enhance its broadcasting and network business and ProCoder is now a Thomson GrassValley product. (It is not trademarked, however, as Harmonic Corp. owns the name.)

This is a frendly file of Canopus PreCoder program.
pnxservr.exe (which launchs pnxkernl.exe) is a file of Canopus ProCoder. They enable ProCoder to run queued batch conversions. To disable open "Job Queue Manager" and uncheck "Start Kernel with Windows" under "Tools" menu. It's not dangerous, but might use too much CPU
It's strated by Canopus ProCoder 2
came with the precoder that I installed.
Part of Canopus Procoder Encoding Program
I have had many problems with it in the past. It came with the Canapus Procoder program but then started acting up. It slowed up my computer(s) by causing my hard drive to run at full speed all the time doing nothing. When I disabled it using taskmanager it froze my computer requiring a shutdown. I then uninstalled the Canopus program and it fixed the problem. In my opinion it is either something inherentlly wrong with the program or the program is being used by some malware. Likely the latter since it works fine for a long time and then becomes a huge problem after months of use.
Ran atfer i installed Procoder2. Uses alot of cpu but only for a short time after booting pc
This is a frendly file of Canopus PreCoder program
Belongs to Canopus PRocoder 2
It uses way too much CPU and should be turned off if your startup times are increased or if your system freezes up during startup
Slows down pc a lot, if don't need it get rid of it
procoder process
part of procoder 2. Just do what "gj" writes if it takes up 2 much cpu.
It's a canopus procoder file, not sure what for, but, besides eating the first minute of CPU at startup, it's harmless
  Lightman   (further information)
ProCoder queue manager service for batch conversion. Not required to be running for standard conversions. Recommend you shut it down if you don't batch process.
Just an Application of Canopus ProCoder, but it causes a lot of Problems (i.e. I had a lot of Problems with that Prog.;-)
  helpy, the helpman  
causes problems on my machine, makes machine freeze on times
GJ is entirely coorect. The only drownback is it uses too much CPU. Not a problem on a fast/dedicated system. Can be disbled, ProCoder works as well but might take longer.
Server for encoding with Canopus Procoder - essential for background encoding using the "Watch directory" function, otherwise not always needed.
yes it is associated with Procoder 2. But we must disable auto start of this programme. I find that it is interfering with many programes.
Assuming you have installed Canopus ProCoder, this is not harmless. Its just annoying. In "C:\Program Files\Canopus\ProCoder 2\" run PNXMANGR.exe, open the Tools menu and uncheck "Start Kernel with Windows"
I am using conopus, that is correct.
It's Canopus Pro Coder batch kernel. If you don't need this feature - disable it in configuration console (I see the apropriate article above).
  Kirill A. Plesch  
used by procoder 2, desactivate it unless you wish to use job queue
Harmless file of Canopus ProCoder. Only needed if you do a lot of batch conversions of Audio/Video. I only use it in the "Editing environment" for which i have a seperate partition/OS. On my other partion/OS I shut it down like gj stated: open "Job Queue Manager" and uncheck "Start Kernel with Windows" under "Tools" menu...
  Gman   (further information)
Procoder background file. Causes the computer to announce that the Dongle is not present if it is not in the USB port at boot. This seems silly for a program that, can be installed on multiple machines, but only one on one machine at a time as the dongle is required for its operation". Disable it under "Job Queue Manager"
To disable this service go to Canopus ProCoder 2 Queue Manager - Tools-Start Kernel with Windows and Stop Conversion Kernel.
This files seems to be locking up my laptop when I am connecting to VPN servers. It is always the file that is not resonding.
  Tony Jordan  
optimum is 100% correct
its eating cpu %97 at first minute of start up
It make the PC boot time longer by using up CPU power and memory. After finishing running, it will release part of the memory. You can still run ProCoder if you end this process in Task Manager.

Best practices for resolving PNXSERVR issues

A clean and tidy computer is the key requirement for avoiding problems with PNXSERVR. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the PNXSERVR.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
