Trying to minimize jitter and posterization (bands) on my new Panasonic ST60 TV when playing 1080p 24 Hz files on WD TV Live 1. gen (latest official firmware 1.06.43).
However, there seems to be a bug in WD TV Live 1. gen. so that there is no nice way of minimizing both jitter and posterization!
If setting HDMI output to Auto resolution/framerate and selecting to match video framerate to file, the HDMI deep color mode is set back to 8 bit. Only if setting ‘match video framerate’ to off is 12-bit HDMI deep color mode available.
In other words:
- Auto resolution/framerate + match video framerate on => no 12-bit HDMI-deep-color = posterization.
- Auto resolution/framerate + match video framerate off => always 50Hz = jitter in 24Hz files.
- Fixed resolution/framerate (e.g. 1080p24 or 1080p50) => minimize both jitter and posterization, BUT result in jitter in files of other framerates.
Please, can anyone confirm this limitation/bug?
Also, does anyone know if this has improved in later WD TV Live generations?
Thanks in advance for all comments!
PS. Searching the topic I found quite a few comments that 12-bit deep-color has no advantage given the current data format of DVD/BD. This is very wrong. 12-bit deep-color has a considerable improvement on reducing posterization (bands). One post did explain that it is the image decompression (“Inverse” Discrete Cosine Transform) that takes advantage of the higher bit depth.
