not honoring duration settings #120

Found you have beta versions if you click on the full list of compiled versions. That said, when I set it to check 10 minutes, and say to skip the first minute, it keeps going past that duration unlike the last release version. Currently on 44k+ frames and growing for a video with 23.976 fps.

Could you follow troubleshooting steps and provide ffmpeg command line from log please?

I've just tried the latest 1.4.8b and in my case, when specified duration set to 5 seconds and skipping set to 5 seconds, I have in log: 2023-08-06 16:05:06 ffmpeg -hide_banner -nostdin -r 29.97 -i C:/Path/To/Distorted.mp4 -r 29.97 -i C:/Path/To/Ref.mov -frames:v 150 -lavfi [0:v]trim=start=5,settb=AVTB,setpts=PTS-STARTPTS[main];[1:v]trim=start=5,settb=AVTB,setpts=PTS-STARTPTS[ref];[main][ref]psnr=eof_action=endall:stats_file='-' -f null -

Both files are 29.97 fps so specified -frames:v 150 and trim=start=5 are correct and I see 150 frames on plots.
