Let me ask it differently : do I use the same script for a 2.35:1 source and a fullscreen one ? According to you... ? ;-) |
@Dialhot
:lol: No, sorry for asking my dumbass questions. :wink: But, is there an easy way of using different scripts for different parts of the DVD? |

When I use DVD-RB I do not do any crop/resize. I just put filters in the script and let DVD-RB take care of other issues. |
Okay, here's an abridged summary of the scripts mentioned in this thread. Can anyone suggest which one they're most pleased with? (All filters are placed between resizing and addborders)
incredible, Feb 23, 2004 Code:
Deen("a2d",1,3,5) # Only if spatial filtering is really neededCode:
Undot()Code:
RemoveGrain() # note, mode=2 is defaultCode:
undot()Also: Quote:
There is also an active removegrain+removedirt thread in the avisynth forum. I think this thread is more relevant for me because I too am going for 1-to-1 dvd movie encodes (although I haven't tried dvd-rebuilder yet. Better than dvdshrink I presume?). From my own experience I've had good results with removegrain as an undot replacement. But removedirt at default settings can cause "twinkling" of pixels which I find very bothersome. Like Jorel I'm just trying to keep this thread alive! :D |
@J-WO,

winner. With undot-asharp-deen, encoding is much faster and quality is similiar to MA script. :wink: I believe it takes time to test these scripts, so that why no quick resopnse. This post is still alive, but comparing is subjective. :) -BP |
Thanks for the opinion blackprince. For me I'm not entirely convinced that any script with deen is so good anymore. I think deen adds more macroblocks than it removes... I'm also going to experiment with replacing undot with removegrain to see if that makes an improvement. Hopefully with time we can all decide on a new definitive optimal script!
But just to add more fire to the flame, here's my own script that I used in the past to handle grainy dvd sources: Code:
removegrain(mode=8) # mode=2 may actually be better/sufficient |
okay guys, I did some more testing of my script vs jorel's script. I have to say that for me personally, I'm not pleased with any undot.deen combination. It just creates too many macroblocks and such, especially on smooth backgrounds. I also realized that DCTFilter isn't needed, as I guess everyone else has already discovered. Visually I don't see any difference with it in or out but it does increase filesize which is not a good thing. Finally, removegrain(mode=8) tends to remove too many details and also create some macroblocks, so for now I'll stick to default (mode 2). So here's my personal script, which is excellent for grainy and clean DVD sources:
Code:
removegrain(mode=2)Hope you guys can provide some comments or suggestions! |

One thing: Asharp1,2 does "plain" to much! Check hairs and skins! Only use 1,4 or "try" 1,3 .... as everything below smoothes non-edged areas ;-) BECAUSE: Asharp is NOT only an adaptive sharpener (based on edgedetection) but also a smoother! Means when using 1,2 beside sharpen edges, also normal areas and for shure surfaces will be plained. And that after an already processed spatial work *wow:!: Try for TV purposes also Unfilter(60,0) (or was it (0,60) ... Well I check that) instead of asharp() . :) |
thanks inc, I was confused why I wasn't seeing much sharpening with asharp but instead some lost details! Let me know which unfilter settings I should try. However I'm not too sure if I need to do any sharpening, as my source is anamorphic 16:9 and so is my output.
So I finally figured out how to implement Dialhot's suggestion (on pg 1 of this thread) which requires no lanczos or bicubic resizing, which will always loose sharpness/details. I refined his coding however so it makes a little more sense and is not PAL/NTSC specific: Code:
mpeg2source(whatever.d2v)x=16 for 1.85 anamorphic source x=32 for 2.35 anamorphic source So when I finally figured out what all these numbers mean. In the first line you are cropping 8 pixels off the left and right side which brings the resolution down to 704x480, an acceptable dvd resolution. And then values for x represent how much is cropped from the top and bottom. These values represent overscan=2 parameters, so you can feel free to inc or dec x according to what your TV can handle. Finally the addborders line adds black bars to the top and bottom (i.e. letterboxes) so again you get a final res of 704x480. I got a pm from someone who suggested this be made a sticky in the avisynth forum. What do you guys think? |

Telecide(order=1, guide=1, gthresh=10, post=2, vthresh=50, dthresh=7, blend=false, show=false) Decimate(cycle=5, mode=0, threshold=0, threshold2=3, quality=2, show=false) |
This is a slow but clean script I use for 1 cd per TV episode cap:
converttoyv12() telecide(order=1) decimate() GripCrop(704, 480, overscan=2, source_anamorphic=false) GripSize(resizer="LanczosResize") DeGrainMedian(limitY=5,limitUV=10,mode=0) VagueDenoiser(threshold=1.0,method=3,nsteps=6,chro maT=1.0) GripBorders() Tell me what you think. http://home.comcast.net/~dfsuth/images/trek.mpv |
Result are good but perhaps a little too smooth. VagueDenoiser is know to be very powerfull and you should even try without DeGrainMedian.

IVTC and MA script do not interfere, i.e. you can do the IVTC and use the MA script. Although I wouldn't use it for DVD encodes, too much filtering IMHO. |
Mpeg2Source("*.d2v")
Telecide(order=1, guide=1, gthresh=10, post=2, vthresh=50, dthresh=7, blend=false, show=false) Decimate(cycle=5, mode=0, threshold=0, threshold2=3, quality=2, show=false) Crop(8,60,704,358) removegrain(mode=2) asharp(1,4) #optional TemporalSoften(2,4,6,6,2) AddBorders(00,60,00,62) The actual script I'm trying (Phil's one disk DVD script modified for NTSC and my source). The source is 2.35 (16:9 Film in DVD2AVI) with anamorphic in, anamorphic out (TMPGEnc Video Aspect Ratio set to 16:9). Length is 200 min. CQ ends up as 80.5 with CQMatic. Sound is Headac3he 192/48. |

I also use DVDShrink 3.2 to fit final size (98.5 for this one). Deep Analysis, Sharp(default) |

Your borders also look weird, where did you get the values? |
:D Thanks, Boulder.
Will try ForceFilm. I've read other places that it was better to IVTC in avs. My borders are exactly from Clip in TMPGEnc. When I use DVD2AVI, I cannot set exactly. Is it better to just use clip values from DVD2AVI that include some of the top/bottom borders but does not clip video area than the way I am using? When I use DVD2AVI, I have to choose clipping a few pixels of video or leaving a few pixels of border. Also, I usually just use Phil's script and process interlaced as anamorphic when things fit. |

When a source is VIDEO, then it is telecined and then you have to use a IVTC in the avs. |
Why use DVD2AVI for cropping?
I open the script in VDub, find the crop parameters manually using the null transform filter for example and enter them in the script (Crop(left,top,-right,-bottom). Then I open the d2v file in FitCD, feed those crop values and it gives me the correct resizing and AddBorders parameters which I add to my script. Even as we are doing DVDs, there's still no reason not to use some kind of overscan as compressibility increases quite nicely. |
