[RISOLTO]tagliare video con ffmpeg

[poccino]

Uso ubuntu 22.04
volevo estrapolare un pezzo di video e seguendo una guida su uinternet, ho dato il comando

ffmpeg -i input.mp4 -ss 00.14.00.0 -to 00:37.00.0 -c copy output.mp4

.
Il terminale però non l''accetta,

Codice: Seleziona tutto

Dov'è l'errore?

Time duration
There are two accepted syntaxes for expressing time duration.
[-][<HH>:]<MM>:<SS>[.<m>...]
HH expresses the number of hours, MM the number of minutes for a maximum of 2 digits, and SS the number of seconds for a maximum of 2 digits. The m at the end expresses decimal value for SS.

grazie, ma continuo a non capire. Mi sembra di avere scritto come indicato nel manuale

Desidero estrapolare la parte dal 14' al 37'

Codice: Seleziona tutto

ffmpeg -i input.mp4 -ss 00:14:00.0 -to 00:37:00.0 -c copy output.mp4

Sono i due punti : a fare la differenza.

P.s. non fare post consecutivi. Se vuoi aggiungere qualcosa ad un messaggio basta utilizzare il pulsante con la matita.
