Hello

 

I want to cut the audio from a scene of a movie (blu-ray 23.976 pfs).

I want to create the cut from frame 2928 to 5177.

Currently I don't know where I have to cut the audio to be accurate.

Is the given command correct?

 

ffmpeg.exe -i audio.flac -ss (2928/(24000/1001)) -t
(5177/(24000/1001))-(2928/(24000/1001)) -codec flac audio_cut.flac

ffmpeg.exe -i audio.flac -ss 122.122 -t 93.80204167 -codec flac
audio_cut.flac

 

And from the documentation I should use -ss as an output option to be
accurate. But what is with -t? As input or output?

 

Best

Felix
