I want to make a fade out in a video, using the afade audio filter.
Here's my command:
ffmpeg -i VIDEO06.mp4 -c:v copy -af afade=t=out:curve=hsin:st=00:0:30:duration=00:00:10 VIDEO06-faded.mp4
But appearantly that's wrong, because
':' separates the filter arguments.
How can I specify the time in H:M:S format (here's ffmpeg's duration syntax) within the params? Or how can I escape the colon?
