好奇怪，睇明珠台又唔覺
有颤動，85台隔二至三分鐘
就会疾，尤其是黃金時段

什麼位置有顫動？係咪同一位置先？通常睇波時個波在觀眾席上會顫動得好勁

我知道睇足球或快動作会有，
但是看85(而家是81)黃金時
段劇集，人物角色(多數是
臉部)、就會輕微颤動。

今晚睇公公出宮係好多位起格同局部窒一窒，係之前睇咁耐一路都無的。可能今晚係訊號問題。

我喺未再重新搜台前已經有，
但看peral 84台冇这現象，費解

我懷疑係個別台的問題，多過部機的問題。

的確尋晚轉咗新81台後明顯多咗颤動問題, 係唔係淨係P記係咁?

有, turn off 咗係好啲, 但之前一直turn on都無咁嚴重, 會唔會呢次tvb signal restructure有影響呢?

I think yes, possibly, because motion interpolation is content-dependent.  TVB seems to have changed encoding in addition to increasing the bitrate.

Regardless of brand or model of TV, any attempt to make video smoother by motion interpolation is bound to fail sometimes.  It's just a matter of different types of algorithm failing at different types of scenes.  A TV needs to "invent" frames not present from the source.  It's never going to work perfect unless it's as simple as this:
