Incorrect video end time stamp

[noachk]

I recorded the PC (Windows 10) desktop using the convert feature. The actual duration of the video content is 1:59:02 but when playing it in VLC (and in fact in any other media view/editing SW it only shows the first 48:27 duration. In VLC it will continue to play the video but in any editing SW it will go black past the 48:02 point.
How can I change the end time stamp so it enables the full extent of the video stored in the file ?
VLC media player – 3.0.20 Vetinari
