[HELP] Telecine Vatiations Problems, Fixes and Questions...

[shijan]

Here are some tests that may help to understand what is gong on in TIVTC and VIVTC filter settings and probably may help to improve them in future.
Both filters sometimes may appear in situation with complicated combed frame that they attempt to fix. All default settings. Input set to telecine(soft):

TIVTC Deinterlacer: inner - sometimes it produce not too accurate jagged edges on complicated combed frames.


TIVTC Deinterlacer: QTGMC - it attempt to rebuild new frame from both frames. In most cases it look ok.


TIVTC Deinterlacer: NNEDI3 - produce strong interlaced artifact. Have no idea if this is a bug or just something specific to NNEDI3.


TIVTC Deinterlacer: Yadif - produce exact same strong interlaced artifact. Have no idea if this is a bug or just something specific to Yadif.


---------------------------------------------------------

VIVTC Deinterlacer: QTGMC - it attempt to rebuild new frame from both frames. In most cases it look same as TIVTC QTGMC, but sometimes in some places VIVTC QTGMC looks less accurate in small details.


VIVTC Deinterlacer: NNEDI3 - looks near same as QTGMC here but slightly softer.


VIVTC Deinterlacer: TeintMod - this filter seems depends of VIVTC setting Order: 0 or 1.
When set to Order: 0, it produce produce strong interlaced artifact.
When set to Order: 1, looks like it looks ok.
