Echo duration of video in seconds without decimals
Ended up using a batch file to export the timings to a text file and then turncate the value as a set variable.

ffprobe -i {filepath$} -show_entries format=duration -v quiet -of csv="p=0" &gt;&gt; duration.txt
setlocal enabledelayedexpansion
for /f "tokens=1,2,3,8 delims=\ " %%a in (duration.txt) do (
  for /f "tokens=1 delims=." %%i in ("%%a") do set _stime=%%i
)
