Excessive disc reading on opening VPX

Hi

I am experiencing a large amount of hard disk reading on opening VPX. It appears to be related to a project and its folder on my data drive where I have stored a couple of thousand 4K .MP4 files from a recent holiday. About 500 of these have been added to the project, but on opening the program, even before opening the project, task manager shows that it is systematically reading every file in the folder simultaneously with the processes Video_Pro_X.exe and MsMpEng.exe. The latter is related to Windows Defender's Antimalware protection and after googling I have tried excluding VideoProX's process and the data folder from the Win Defender realtime scan but with little improvement - although it appears to have stopped the MsMpEng reads but not the VPX ones. The reading activity takes several minutes, and if the project is opened before the disc activity stops then I get messages that VPX can not find a few of the files in the project, and relinking needs to be carried out for the project to load completely.

The MP4 files I had also duplicated in another folder so I wondered if this was triggering an alert in Win Def., as if the duplicate files were been seen as bogus, but deleting the duplicates bought no relief. Interestingly one of the google results of MsMpEng / disc activity pricked up my ears when the guy said he became aware of the problem whilst searching a folder for duplicates of .jpgs but this may have been incidental to the problem.

Annoyingly I had experienced this once before but I cannot remember the remedy and was not sure of the cause. I think it is more of a windows problem than a VPX one.

Anyone have any ideas on this?

Hi Peter

What are the affinity settings for Windows Defender?

To check/change

  • Open Task Manager
  • Go to the Details tab
  • Right click on the process name msmpeng.exe and select Set affinity
  • Select the CPU limit for the process to use

Hi John

Thanks for the tip and I did see that in some of the googled solutions but it is more the disk thrashing than the CPU usage that was preventing normal operation.

However I have been able to solve the issue by the following:-

  1. Create a new folder xxxxPart1 for the project and cut and paste just the MP4 files used in the current episode of the project, rather than all the files recorded on the holiday. Delete any created HDP's from the original storage folder.
  2. Create a new folder for all the remaining MP4s and give that a new name. From there I will cut and paste just the files needed for the next episode to a new created folder ie xxxxPart2.
  3. Open the episode in 1. and relink the xxxx.MP4 cannot be found to the xxxxPart1 folder.

All is normal again but not sure why this issue occurs.

PS. Will respond to your PM with some thoughts on the Sony AX53 shortly.

Cheers

Peter

Hi

Just an oddity with the method I used above is that anything I had stabilised with Mercalli V4 prior to moving the files and relinking needed to be re analysed after coming up with the banner across the clip which said "Analysis required Clip exchanged". The clip had been copied and pasted only....but who knows how Mercalli keeps track!
