SansGrip Filters: Which filters are best for what?
 

Having just started using avs scripts to do the file prediction (using KVCD Predictor) I've also started tinkering with the (many!) filters available. There seem to be a myriad that people use and I was wondering if there was any broad consesus about what to use when?? In my case this would be mainly for 16:9 and 4:3 DVD movies.

I've seen people using

Blockbuster - remove blockiness in low light areaas.
Sampler - sample frames from a clip (for the file prediction)
FluxSmooth - spatio-temporal smoothing of fluctuations
Gripfit - GripCrop replaces Crop, GripSize replaces BilinearResize
LegalClip - clipping levels to within CCIR-601 range (for chroma and luminence)
SpaceDust - reduces noise
Temporal Cleaner -if the difference between previous pixel and current pixel is below a blur threshold then replace the current pixel by the verage between previous and current pixel else keep current pixel

is it worth using *all* these in an encode or generally some of them??

I currently have this order for using them, but what options are there:

LegalClip()
GripCrop( width=352, height=288, overscan=1 )
GripSize()
SpaceDust()
TemporalCleaner()
Blockbuster(method="noise", variance=.7, seed=1)
Fluxsmooth()
GripBorders()
LegalClip()


Cheers for the pointers

Hi miksmith,

Here is some comments :

with the DVD sources (16/9) dont forget to precise source_anamorphic=true
with a 16/9 TV you have the choice between anamorphic (dest_anamorphic=true) or not (by default)

You can specify the resizer i.e : GripSize(resizer="yourChoice")
with yourChoice = {LanczosResize,biCubicResize,bilinearResize}

I don't think that fluxSmooth is necessary after SpaceDust and TemporalCleaner.

Some people seem to have problems (illegal operation during encode with TMPEGEnc) with Dust :cry: . I put GripBorder() before applying (Space or Faery) Dust.
