I'm experiencing an issue where videos under 25 seconds are not rendering completely. Specifically, as soon as a file is opened, the last dozen or so frames—about one second—are cut off and not displayed on the timeline.
For example, a 1.79-second video renders as 1.33 seconds, indicating a loss of approximately 15 frames.

Operating Environment

  • OS: Windows 11

  • Software: Kinovea ver1.2

  • Video File Format: mp4

  • Frame Rate: 23.98-24 fps

Hi Joan,

Great job on 2025.1

I have the same issue as this on Windows 10, with the Kinovea 2025.1 playback window. My video is 21 frames long, but the replay screen only gets to frame 13, then cycles round to frame 1 again. The working zone boundary is set from 0 to 13, and immediately returns to 13 even after dragging the right hand working zone boundary to frame 21. 

I've worked round it by appending the last frame to the video I'm creating multiple times (10). This allows me to use Kinovea to both record the video clip and display the results after doing some video analysis.

If you need a video clip to test with let me know.

Many thanks
