When rendering my animation video with ffmpeg, I want my video to start with 28-odd seconds of silencebefore the soundtrack begins.
(Well, I really want it to be 0.28 seconds but making it longer makes debugging easier.)
Here's my command line:
ffmpeg -y -itsoffset 28.84 -i soundtrack.wav -framerate 30 -i %d.png -r 30 -vcodec mpeg4 generated.mp4
It generates the video, but the soundtrack starts immediately.
I am stll new to FFmpeg, so I assume I am missing something obvious.
