Let me add that I did not "tell" that. Case of overinterpretation ... I showed two code sniplets that handle luma ranges for masking, one for 16-235 range, one for 0-255 range, and happened to place the string "BT.709" beneath string "0-255" in a small #codecomment. (Assuming that if you encounter a 0-255 source, it'll probably be BT.709...)
  Tried to avoid "but what-if-" nagging by showing both possibilities, got nagging I would have made a claim. Oh well. Guilty for incautious wording. Changed to PC/TV range.

source :
 agc + smoothlevels(pc2tv) (final script doing everything necessary ie deinterlacing , denoising and a lot of other stuff ) :  p.s : did the a.r correction as i deemed appropriate for the testing , also screens taken using print screen so sorry if the pixels are off ( yeah i know prtscrn+paint+crop+save as .png sucks ) but what to do no other option  input please ? to my eyes smoothlevels aka ulevels seems to darken the picture a bit up ? used chroma=0 , will test more and post results  edit : i know they're annoying(the lines,but thats how the source is ) ( perhaps about time i updated my sharpening arsenal , giving lsfmod a shot in a bit , will post results )

If it looks good to your eyes, then it's fine. Asking everyone else for their own opinions will only cause you to filter the video to how they want it. If it looks good enough for you to watch, then what does anyone else's opinion matter?

LaTo, I've probably discovered a bug. Both SmoothLevels(gamma=1.0, Lmode=1, DarkSTR=250, BrightSTR=250) and LimitedGamma2(gamma=1.0,dark_str=250,bright_str=250) create black dots on white surfaces around edges.
These pixels are pure whites (255, 255, 255) originally (looking them at in RGB colorspace), but not all of them becomes black. (Perhaps a rounding error?)

Code:
ImageSource("LimitedGamma_bug_default.jpg").ConvertToYV12()
#SmoothLevels(gamma=1.0, Lmode=1, DarkSTR=250, BrightSTR=250)
LimitedGamma2(gamma=1.0,dark_str=250,bright_str=250)
Please post your script & a sample EDIT: Be sure that MaskTools is up-to-date (v2.0a35) and use the good .dll (mt_masktools-25.dll) Last edited by LaTo; 14th December 2008 at 17:40. |

It seems it depends on source. Your script with ImageSource() works fine. But loading the original .D2V/.M2V file (taken from a DVD), the black dots appear again. I use AviSynth 2.5.7. The filters seem fine too, they're all the needed versions: mt_masktools-25[2.0a35].dll .................. 2008.04.19 11:02 ...... 724,992 bytes gradfun2db[1.0].dll ................................. 2006.03.15 21:49 ...... 61,440 bytes SmoothLevels.v1.00.avsi ....................... 2008.12.14 15:57 ...... 20,313 bytes RemoveGrain[1.0].dll ............................. 2005.07.31 23:07 ...... 27,648 bytes My script: Code:
LoadPlugin("mt_masktools-25[2.0a35].dll")
LoadPlugin("gradfun2db[1.0].dll")
Import("SmoothLevels.v1.00.avsi")
LoadPlugin("RemoveGrain[1.0].dll")
MPEG2Source("TD_Joy_Sales_sample.d2v")
ConvertToYV12()
SmoothLevels(gamma=1.2, Lmode=1, DarkSTR=250, BrightSTR=250)
What's wrong?

Hey,
Just wanted to say thanks for this nice little script! Works like wonders, especially since the first stable release. (darkstr & brightstr = ^_^)
