Setting duration is not working in ffmpeg

Question

Have problem with creating video from 50 png files in ffmpeg in shell. Setting duration -t 5 and fps -r 10

ffmpeg -i image%d.png -y -pix_fmt yuv444p -r 10 -t 5 -s 1920:1080 out.mp4

Final duration is 2 seconds and fps is 25.

How to set it correctly?

I'm running at elementaryOS, ffmpeg version 0.8.10-4

Thanks

Answer 1

The solution is
ffmpeg -r 10 -i image%d.png -y -pix_fmt yuv444p -t 5 -s 1920:1080 out.mp4

Need to set fps -r before input data.
