Hi, some time ago I also confused by this... "-itoffset" work for all
followed input stream. Just replace positions of input streams:
ffmpeg -r 60 -i final/%07d.png -itsoffset 26 -i main.wav out.ogg
Same situation is a with "-ss" and "-t" options. Good idea if you
cutting video is to place this options after all input streams (more
ffmpeg -i video -i audio ... -ss 00:01:00.000 -t 00:30:00.000 -f ...
