I am not quite satisfied with the motion smoothness of the Samsung. Using the moving bar patterns on the GCD disk, I have now optimized the Samsung. Motion smoothness is OK for 24fps, but there is some stuttering left at 50fps. That should be OK for Blurays at 1080p24.
I wonder now what settings I should use on the Oppo for STB operation. The STB puts out 1080p@50Hz . I was thinking if I select 1080p24 Forced on the Oppo, the Oppo would convert the STB signal to 24p which is best for motion smoothness on the Samsung. However, if I do that, the info from the Oppo still says that HDMI1 is 1080p50Hz 4:4:4 24b. So it does not convert to 24p, even with 1080p24 set to Forced? (Also, what does 24b mean?).
What setting is best for STB operation?
(And another question, for operation with my Samsung 55F8000, which color space to choose: 4:4:4 or 4:2:2?).
Any help is appreciated. Thanks.
There is no forced conversion to 24hz. In the case of NTSC DVD which is 480i60, the 24hz cadence can sometimes be recovered with inverse pulldown, but there is no pulldown in a 50hz signal from which to recover 24hz video.
For 23.976/24.0 sources like most film-based Blu-rays, the 1080p24 Output
setting allows the original frame to be transmitted (when set to On
) or converted (when set to Off
) to 60 or 50hz, depending on how you have TV System
Color space: in theory it shouldn't matter, but in practice not all displays handle all color spaces correctly, which is why OPPO gives you a choice. It may depend not just on the model of your display, but on its firmware level and other settings.
Spears & Munsil have an article on choosing a color space using the patterns on their test disc. If you want to get into it it's something you have to check yourself.
I have older Samsung display and use RGB Video. I haven't revisited the issue for years but at one time it had some flakiness in its Setup making YCbCr color spaces unreliable.
