27
3d_comb_noise_sns 0
Larger values allow more temporal comb for noisy RF signals but
may also introduce motion error
28
3d_comb_chroma_sns 8
Larger values decrease 3D comb motion detection sensitivity to
chroma motion and noise
29
3d_comb_chroma_sns 8
Larger values increase 3D comb motion detection sensitivity to
chroma motion and noise
30
3d_comb_luma_core 8
Larger values decrease 3D comb motion detection sensitivity to
luma motion and noise
31
3d_comb_luma_sns 8
