CCE Low Pass Filter and other quality settings

[eon_designs]

Hopefully a very easy question to answer: searced for the low pass filter - but came up with nothing useful.

Been looking at CCE SP trial - under the QUality Settings there are some settings I am not familiar with. Anyone able to explain what they are and what effect they have on the output.
(FYI - trying it to convert captured tv episodes and convert to DVD)

1. Low pass filter? - has settings from 2 to 10
2. Effect restricted Vertical Filter? - settings from 1 to 128
3. Dithered quantization? - has settings from 1 to 128

If anyone can explain what they do - or point me to a link that describes them.

Many thanks. eon

Hi-

It's all in your manual.

The low-pass filter filters out high frequencies. It smooths. I keep it off for DVD reencodes.

The manual says the vertical filter reduces "speckle noise" whatever speckle noise is. I always thought that a vertical filter was a spatial filter. In any event, I don't knowingly apply spatial or temporal filters to my encodes, and keep it off.

Dithered quantization adds noise to the encode, which is the last thing I want. I keep mine off. It's supposed to help with "contouring artifacts", but since I've never seen any artifacts of that type, I have no interest in it. Any filtering I want to do, I do using AviSynth.

For encodes of material other than DVD stuff, I can see how you might need some of these. For DVD reencoding, where you want to keep as much of the original detail and sharpness as possible, even the default settings for these filters is too much, in my opinion. Others might tell you differently.

Read your manual.

Thanks for the reply -

Just did a bit of digging on my sysytem - had not realised the manual was there with the trial version - It's a sunday - brain not fully engaged yet
