Can't get Deblock() to work

[whiteshark99]

can some one tell me if this is looks on. Deblock() can not get it to apliy to my file thanks to all.

using vbubmod.


MPEG2Source("C:\Users\Graeme\Desktop\Al.d2v",cpu=0)

ConvertToYV12()
Deblock()
Crop(0,8,- 0,-8)
Lanczos4Resize(624,336)

The script is correct, and the deblock() filter *does* apply.

- Perhaps your video is interlaced? (Deblock is only for progressive content)

- Perhaps you need stronger setting? (like deblock(quant=40) - default is "30", maximum is 51 or 64 depending on implementation)

- Perhaps you're looking for the wrong thing? ("Banding" in flat areas often gets confused with "blocking" - but a deblocking filter will not help against banding)

From DGDecode Manual v1.5.8 (YV12 Only)

quant: 0 to 51 (default: 25)


From DeBlock() plugin manual v1.2 [YV12 + YUY2, Use DeBlock_Deblock() to use it instead of DGDecode version]


quant : the higher the quant, the stronger the deblocking. It can range from 0 to 60.

aOffset : quant modifier to the blocking detector threshold. Setting it higher means than more edges will deblocked.

bOffset : another quant modifier, for block detecting and for deblocking's strength. There again, the higher, the stronger.

Defaults are quant = 25, aOffset = bOffset = 0. If quant + aOffset is inferior to 16, the filter does nothing at all. The same goes for quant + bOffset.

There is a thread lower down on the current (at time of this post) 'Avisynth Usage' page:-

"Color banding and noise removal"

Sure. There are hundreds of filters that might work.

Aaaah, now I remember.

It's THAT time of the year again, your annual popping-up with the ever-same, ever-poor, 10-years-old 700kbps Xvid rip of Aliens.

Shall I buy the DVD for you? :rolleyes:
