 > What's wrong with {{{ffmpeg -ss 1 -i ...}}}?

 It does not trigger the problem
 ffmpeg -i ball.png test%02d.tga
 ffmpeg -ss 1 -i ball.png test%02d.tga
 create identical sequences of 20 frames

 ffmpeg -ss 4.4 -i ball.png test%02d.tga
 creates single (last) frame

 I dont understand what 4.4 means here. The whole duration must be 20
 frames/13.33fps = 1.5s.
