Extract image from m2ts

[Overdrive80]

Hi, I got extract image from m2ts of my Bluray but I dont know if I am using proper way. I gonna to explain my way:

1. Create dga file with DGAVCIndex.
2. Create avs file
3. Open avs file in virtualdub
4. Export file as tga.

Would be correct for saving maximum quality of image?

Example file: http://db.tt/yBSbx1Fy

Thanks.

EDIT: Eac3to doesnt open this file.

That should be fine with two caveats:

1. Your source is not PAFF, which can produce artifacts with DGAVCDec.

2. If VirtualDub does an improper upconversion to RGB, then you would have to do it properly in your script. I refer to the possibility of the chroma upsampling bug.

Respect to first point, would be more proper to load with ffms2?

Respect to secong point, are you refering to use ConverttoRGB32() in script?

Thanks.

Respect to first point, would be more proper to load with ffms2? More proper would be DGDecNV, which handles PAFF correctly. ffms2 has its own share of difficulties with some stream types.

Respect to second point, are you referring to use ConverttoRGB32() in script? Yes, but be sure to set the interlaced parameter correctly.

Sinc it's native progressive blu-ray, then there should be no problems with DGAVCIndex

He's referring to CUE (chroma upsampling error), where either progressive is upsampled as interlaced or vice-versa (chroma notching artifacts). It's a long story, but Vdub doesn't acknowlege the existence of interlaced YV12 , so it upsamples the interlaced chroma as progressive. This won't affect you since it's native progressive BD

Also, Vdub always uses Rec601 for RGB conversion, so you should use ConvertToRGB(matrix="rec709") for HD blu-ray content
