VirtualDub: Why is my avs to avi conversion Dark?
 

Here is the procedure that I used
The source is a ripped VOB (16x9,Film)

DVD2Avi 1.76
============

Feild Operation = Force Film
ColerSpace = YUV
YUV->RGB = TV Scale

Saved project to D:\video.d2v


AviSynth 2.07
=============

LoadPlugin("C:\Program Files\AviSynth2\plugins\MPEG2DEC2\MPEG2DEC2.dll")
Mpeg2Source("D:\video.d2v")

Saved script as D:\video.avs


VirtualDub 1.4.13
=================

Opened Video File D:\video.avs
Changed Video Compression to Divx5 and set to 1st pass quality 2, no other options were chosen
Changed Video to Fast Recompress
Saved as avi to D:\video.avi


When the avs is viewed in VDub it looks as it should, but the produced avi is very dark

If I dont use the video.avs and open the video.d2v in Vdub the produced avi is visually correct

I have tried every combination of things I can think of in the avs script, converttorgb, converttorgb32, etc
Even created a new d2v file and chose colorspace as rgb, etc
Also tried different mpeg2dec files, mpeg2dec, mpeg2dec2, etc

If anyone has any suggestions, please help

Thanks

I completely resolved the issue by doing the following

DVD2Avi 1.76
============

Feild Operation = Force Film
ColerSpace = YUV
YUV->RGB = TV Scale

Saved project to D:\video.d2v

VFAPI 1.05
==========

Opened D:\video.d2v

Saved as D:\video_d2v_vfapi.avi

AviSynth 2.07
=============

AviSource("D:\video_d2v_vfapi.avi")

Saved script as D:\video.avs

VirtualDub 1.4.13
=================

Opened Video File D:\video.avs
Changed Video Compression to Divx5 and set to 1st pass quality 2, no other options were chosen
Changed Video to Fast Recompress

Saved as avi to D:\video.avi

All is well again =)

It appears that by not using any version of mpeg2dec, the unwanted darkening effect didn't happen
After solving that problem, I went on to add the other things into the avs script
which was the reason for using it, as I could have just used VDub's filters and the d2v


I used the following avs script, and the results were very good

LoadPlugin("C:\Program Files\AviSynth2\plugins\LegalClip\LegalClip.dll")
LoadPlugin("C:\Program Files\AviSynth2\plugins\Dust\DustV5.dll")
LoadPlugin("C:\Program Files\AviSynth2\plugins\Convolution3D\Convolution3 D.dll")
AviSource("D:\video_d2v_vfapi.avi")
ConvertToYUY2()
LegalClip()
Crop(0, 58, 0, -64)
BilinearResize(640, 272)
FaeryDust()
Convolution3D(preset="movieLQ")
LegalClip()
