Hello John. When I copy a video file from SD to PC and open from PC- the problem exists, duration 00m-1s.
I need to rename the file, just add a few letters in the file name and this solves the issue. You can see the screenshot in post #794
I can rename the file directly on the SD card, no need to copy on PC - this also fixes duration and shows correct 3:00.
And when I rename the file again to its original file name - the duration again is shown as 00m-1s. On PC and on SD card.
May be something related to current VIOFO firmware I am using and 128GB card.
Hello @traveler John,
I've continued my tests and found that disabling GPS CACHE option FIXES the duration problem immediately.

Now I can read all video files directly from my SD card and time duration is correct!

The loading time increases, but duration fix is worth it.
No need to copy files on the PC and rename them.

FYI, mine is enabled and no issue.

Good find though.
I pushed the test on this direction when I realized that renaming the file forces Dashcam Viewer to read its data again when I load the renamed file.
And when I restore the file's original file name - when loading Dashcam Viewer sees this original name inside GPS cache and duration is shown again as 00m-1.
So for my PC - GPS cache is not working (or building) OK, only John could find what is the possible problem.

OK, that explains it. What happened was that the cache became "poisoned" when the videos were loaded for the first time. Somehow, the video durations, which are cached, were stored in the cache as 00m-1s. That means every time you tried to reload the video file, Dashcam Viewer went to the cache instead of reprocessing the video. By changing the filename of the video, you created a new cache entry, which had the correct data.

So the fix for you would be to:

1. Open Preferences (Advanced) window
2. Click the Clear Cache button. This will delete all the cache files allowing you to start over again. Alternatively, you could click Reveal Cache and find the cache file names corresponding to the problem files, and delete them individually.
3. Enable caching by clicking the Enabled checkbox.

The cache is a good thing because it speeds up loading of GPS data by 100x or more (depending on the camera). The problem is that once bad data gets into the cache, it must be deleted or else it keeps popping up.

Hi John. Currently running the SG DCV at v3.2.8 and run into the following problem - when I try and export a movie clip the whole program just freezes and then the icon in the task bar just starts flashing but the export window never actually opens.
I'm in Windows 10.
Any help please?

@Tom899 I just tried switch between Fill and Maintain aspect modes with the latest version of Dashcam Viewer and had no issues (Win10 i7 ASUS laptop).

I suggest trying the hard reset procedure (it tends to fix strange issues):
  1. Quit Dashcam Viewer
  2. Hold down the Shift key
  3. Start Dashcam Viewer
  4. You will see a dialog box come up asking if you’d like to Reset All Settings. Click “Yes”.

Note that you'll need to re-enter your registration code after you click Yes.

John, Nvidia came out with a new driver Version 461.72 on 02/25/2021. My "Fill and Maintain" now works!

My guess is that the Export Video window is actually appearing, but it's offscreen somewhere. Please try the hard reset procedure to clear the window positions:
  1. Quit Dashcam Viewer
  2. Hold down the Shift key
  3. Start Dashcam Viewer
  4. You will see a dialog box come up asking if you’d like to Reset All Settings. Click “Yes”.

In Dashcam Viewer v3.4.2 and later I added a simple shortcut to force a window to appear in the center of the main monitor:

  1. Hold down the Shift key
  2. Click the Export Video toolbar button
  3. You should see the Export Video window now

This trick works for all ancillary windows too, BTW (Map, Graphs, etc).
