QTGMC output is blurred?
1 Attachment(s)
I'm noticing that deinterlacing is causing loss of sharpness in my captures.
Left side of screenshot is software yadif deinterlace in VLC, right is QTGMC deinterlaced The jaggies on the date and time numbers have been smoothed. I do not like this. How can I stop QTGMC from smoothing the image? My only QTGMC setting is Code:
QTGMC(Preset="Slow") |
Do not use slow. Use faster.
Slow has excess filtering that blurs. That's the difference. |

It's still smoothing it out it seems.
Heres the script I'm using: AviSource("C:\Users\Dave\Desktop\test.avi") AssumeTFF() QTGMC(Preset="faster") Crop(4, 0, -4, -8) LanczosResize(1440, 1080) |

QTGMC reduces jagged shapes created by deinterlacing procedures. This is one of its major benefits, a side effect is the one you experimented on a "real" jagged shape.
QTGMC can rarely be used with its defaults parameters, whatever preset you choose (BTW "fast" in only recommended for speed reason, not for optimal results). Try to use QTGMC's lossless and sourcematch features: Code:
QTGMC(Lossless=2, SourceMatch=3, ...) Code:
QTGMC(preset="slow", matchpreset="slow", matchpreset2="slow", sourcematch=3, tr1=2, tr2=1, NoiseTR=2, sharpness=0.1) |
