Separare audio e video

In questo esercizio dividerai un video pubblicitario del ammorbidente Bounce degli anni '80. Questo è necessario per isolare gli input di immagine e di audio richiesti dai singoli modelli di classificazione di immagini e audio.

Frames from the Bounce TV commercial

I moduli ffmpeg_extract_subclip e VideoFileClip sono già stati caricati. Il file MP4 è stato scaricato come bounce_ad.mp4.

Istruzioni dell'esercizio

Crea un subclip da bounce_ad.mp4 che inizi a 0 s e termini a 5 s, con nome file di output bounce_ad_5s.mp4.
Carica il nuovo subclip.
Estrai il flusso audio.
Scrivi il flusso audio nel file bounce_ad_5s.mp3
