Weird telecine format?

[jagabo]

I went to see which version of DgDecode I had in my 64 bit AviSynth+ folder. It wasn't there! After some experimentation I found a filter called MPEG2DecPlus.dll is doing the Mpeg2Source function in 64bit AviSynth+. A quick search on the web found it.

So now that things are working (well, in a sense) I'm left wondering how best to configure Mpeg2Source. The documentation is fine but not as explicit as I'd wish. I have two questions:

1. info=3 "Output hints in the video (as defined in utilities.cpp/utilities.h)" but what does that do exactly?

2. Post-processing options? Can I leave deblocking on by default? And when would I want to enable deringing?

Oh I did not see your post jagabo, completely missed that the thread had reached 2nd page

So why, Mpeg2DecPlus did fix the 64 bits issue, thank you for that

1. info=3 "Output hints in the video (as defined in utilities.cpp/utilities.h)" but what does that do exactly?

I'm not sure about everything it passes but the most important is that it flags field order. This is critical with some videos.

2. Post-processing options? Can I leave deblocking on by default? And when would I want to enable deringing?

I find its deblocking to be too strong -- it erases too much small low contrast detail. When I need deblocking I use deblock_qed(). I lets you control the strength of the deblocking. I usually use the deringing filters (CPU2="ooooxx") because it reduce the DCT ringing noise around sharp edges, without causing much damage otherwise.

Apparently there is a bug in the 64 bit version of DgDecode.dll. And whoever made Mpeg2DecPlus fixed it.

Hmm sadly the issue isn't fully resolved. It seemed to be working fine until I stumbled upon a DVD where it does not.

It only does that on the first two frames mind you, but that's still an issue. The demuxed m2v from DGIndex does not display this issue, but only because the first two frames have been dropped by DGIndex during the demuxing. That is why I believe there is no problem this time with DGDecode or MPEG2DecPlus. Just to be sure I tried encoding the file using x86 builds and even through StaxRip. Here's the d2v

So what now? I am supposed to strip the first two problematic frames? Has anyone ever run into this issue?

[jagabo]

Don't include VIDEO_TS.VOB.

[ZetaStax]

Wow, that worked. Surprised there are no options in DGIndex to do that though...

Anyways, I might have finally made it through, I learned a lot thanks to you guys, big thanks!

[jagabo]

VIDEO_TS.VOB is not part of the movie. Never include it in DGIndex.

My guess is there's a lot he tried to create a project file for not in the main movie. I think probably only the highlighed VOBs should be included.
