Problem Description

After exporting video from VI and playing the file on most standard media players (Ex. Windows Media Player or VLC), parts of the video are playing back at a higher speed. As if it were being fast forwarded.

If there is a difference in framerate settings between Record Always and Motion Recording, then this phenomenon will be observed.

If this is a concern, consider the following options:
- Playback the video on VI Viewer Plus. It should playback normally
- Consider unchecking “Record Always at 1 FPS”
- Consider recording continuously at a constant framerate

Confirm how the camera is being recorded.

  1. Log into VI Monitor Plus using a VI Admin account
  2. Click the Administration Tab
  3. Click Cameras
  4. Select configure Properties
  5. Select the correct camera
  6. Go to the Recording tab > Recording Type
  7. If it’s set to “On Motion Only” and “Record Always at x FPS” is checked, then this phenomenon will occur

 

Confirmed on VI version 7.9.3
