I added the ti.sharpness and the keyframe you mentioned before and I must say that it is a big help.
I have a much better image in the output file and I can increase the video quality option one more step (from 6 to 7 in my test).
Does the new keyframe value is saving bytes ?
My bitrate felt from around 700 to 500 with the modification of the encoder_example.c.

Thank you for those advices
