Avisynth: Auto crop using avisynth filter beta?
Hi All,
Here's a simple avs auto crop filter. The author is still testing to make this filter keep aspect ratio after crop. This may produce similar results as FitCD. Check it out! :) http://forum.doom9.org/showthread.ph...threadid=37204 Imagine having a built-in FitCD filter. 8) -black prince |

settings to remove black bars, basically cropping the video for full screen (4:3) viewing. In some cases the video appears stretched (egg shaped). The author is planning to add an aspect ratio function to get a normal full screen. This could be a useful filter, since I always like full screen vs wide screen. This is NOT a replacement for FitCD, but is nice option to crop a video for full screen. :) -black prince |
Hi All,
It's just me I suppose, but sometimes I wish a wide screen (16:9) could be converted to full screen without the problems of aspect ratio. You know, the egg head problems. Well, the updated AutoCrop handles this. Here's the link and below is a sample avs script: http://forum.doom9.org/showthread.ph...threadid=37204 LoadPlugin("E:\DVD Backup\2 - DVD2SVCD\MPEG2DEC\MPEG2DEC2.dll") LoadPlugin("E:\DVD Backup\2 - DVD2SVCD\BlockBuster\BlockBuster.dll") LoadPlugin("E:\DVD Backup\2 - DVD2SVCD\LegalClip\LegalClip.dll") LoadPlugin("E:\DVD Backup\2 - DVD2SVCD\FluxSmooth\FluxSmooth.dll") LoadPlugin("E:\DVD Backup\2 - DVD2SVCD\AutoCrop\AutoCrop.dll") mpeg2source("D:\Temp\movie.d2v") # LegalClip() # AutoCrop(false,1,1,0,0,0,0,40,10) # BilinearResize(336,224) # FluxSmooth(temporal_threshold=7, spatial_threshold=7) # #Blockbuster( method="noise", detail_min=1, detail_max=10, variance=0.5 ) # AddBorders( 8,8,8,8 ) LegalClip() For preview use AutoCrop(true,1,1,0,0,0,0,40,10). The above is a sample avs script for KVCD-LBR. :) BTW, I left out Blockbuster sharpen due to it's increasing file size and it made file size predictions way off from the actual encode. Try some tests and see if file prediction keeps changing for the same settings with Blockbuster sharpen. :? -black prince |

Hi SansGrip,

sharpen many times with the same settings just to see if file size would change. It stayed the same. Only when I add Blockbuster sharpen in combination with Blockbuster noise did it change each time. :? I did reduce the variance from 1 to .5. Could reducing the variance have stopped file size from changing :?: My file prediction is back to within + -1% again with just Blockbuster noise in the script . :) Blockiness in dark areas has still disappeared. 8) -black prince |

hope the "New Encoder Team" will find a way to incorporate it into the KVCD encoder being developed. Your right, I still have more tweaking to do and it takes very fine balancing and adjustments to get the best picture quality without dramatic file size increases. You have done an outstanding job and we all know your busy working on various projects to enhance video quality. 8) thanks -black prince |
