Comment:

 Correct command:

 `ffmpeg -y -framerate 30 -i numbers.00%02d.tif -ss 0.33333333333333333
 -start_number 11 -framerate 30 -i numbers.00%02d.tif -ss
 0.3333333333333333333  -frames 5 -lavfi overlay -c:v rawvideo`

 Command you provided is incorrect, `-start number 11` is ignored if set in
 position you gave.
