TVB 星期日早上日本動漫《魔導少年》用左倍幀?

流暢度斷估有 50Hz 但又時不時見到高速畫面會有 artifical
見 OP 出 "A-1 Picture" 字體位,背後 樹木 響字後面移動,不時見到前方字體會跟樹木碎出

有冇師兄證實到呢??

MirageKnight 同 aarv 師兄,其實 60i 都可以係 60 FPS,你玩過 PS2 就知

佢地叫 field ,但個別 field 其實可以同時有兩種
一個 frame 拆成 2 個 field,最終 25 fps
一個 frame 用一個 field,最終 50 fps

YADIF de-interlace 確實不嬲都有 video (50) 同 film (25) 兩個 mode
W3DIF 就點都係出 video (50)

film mode 係 field 1 + 2 = frame 1, field 3 + 4 = frame 2 ... etc
video mode 係  field 1 + 2 = frame 1, field 2 + 3 = frame 2 ... etc

SONY Support 既 Q&A 有講過
What are the differences between 50i and 50p?
50i records 50 frames per second using the interlace scanning system, and 50p records 50 frames per second using the progressive scanning system. 50i is recommended for normal recording.

廣播技術唔深究,我用AviSynth做參考

(AssumeFPS,ChangeFPS,ConvertFPS)



基本上TVB咩嘢片都用Conver ...

師兄,睇下我講得岩唔岩
AssumeFPS = video 本身加速減速,Audio 48000khz 跟 video 加快減慢 (例子 MadVR + Reclock )
ChangeFPS = 就係 drop frame + duplicate frame 去就返 output (例子 MadVR Smooth Motion Off)
ConvertFPS = 就係 frame 1 x ratio + frame 2 x ratio 去生成 frame 1.5 (例子 MadVR Smooth Motion On)

但《魔導少年》感覺上係類似 SVP 果種中間 生成 components 去倍速,又有點不同。。。

唔知有冇搞錯
