VSR Recovery

From time to time we all find a way to crash the daVinci 2K+. This procedure is intended to recover session VSR’s that have been lost as a result of a application crash. It assumes that the high resolution images still exist on the Gallery and we wish to rebuild the VSRs.


Disclaimer: Proceed at your own risk, Please follow common sense computer practice and back up your session before you begin. I am not responsible if you lose data. Please , if you find a better way or I have missed something....feel free to edit this page.


First reboot the Linux system if you have not already done so. Then load the NUI and your original session. Assuming your VSRs did not magically appear; right click on the VSR Display strip and toward the bottom of the pull down menu select “Recover VSRs from gallery”. Be patient the dialog box takes a moment to come up. After the recovery finishes, if your VSRs still have not returned, we can conclude that your session file structure is damaged, to effect repairs continue.

  • Close down the NUI. Exit all the way to the desktop.
  • Click the big “K” Start application on the menu bar.
  • Select <HOME, Personal files> This will open a window.
  • Select File:/home/dui
  • Then follow the path: File:/home/dui/nui/colorists/sessions/your-user/session/jonas.ssn (In this case the User is “Mann”)

In this example the session name is ”jonas”. You should find 6 folders and a text file, seven objects total. A healthy set of directories looks like this:


VSR recover miss 1.jpg
VSR recover miss T.jpg

Now, let’s create new folders. Right click in the session window and select “Create new” then “Directory”. Please rename (F2) this new folder <Yoursession.memVsr>. Beware this is case sensitive. Remember to capitalize the “V” in Vsr. Then create <Yoursession.vsr> in the same manner.

It is possible that the header file <Yoursession.hdr> is also damaged. If so, no worries, we will rewrite this file, in the last step.

Next, close down the window and start the Nui application. Load your session. (The VSRs will still be missing) right click on the VSR Display strip and toward the bottom of the pull down menu select “Recover VSRs from gallery”. Be patient the dialog box takes a moment to come up and the recovery will take some time depending on the size of your session. Your VSRs should come back.


Next perform a “Save as” and re-save you session with a new name. This will rewrite the Header file so that the VSRs will return the next time the session is loaded. Once you confirm that the VSR are back and working you can delete the original session. But you don’t have too. Good Luck.

Those steps work great. We have recently had Rich from DaVinci here in Florida give us a fix for both of our 2K systems that seems to have taken care of the issue of VSR's disappearing when the NUI crashes. I would imagine that the fix they wrote would apply to most 2K's out there with this same issue.

Hope this helps!
