Hi there
I have vob files from a DVD I've decrypted and I opened up the vob's in DGIndex, and selected the scene that I wanted to encode, and I chose "honor pulldown flags" and I opened the .d2v output in notepad and it says 100.00% Video - so I left it as is and didn't choose Force Film.
I then opened the avisynth script creator tool in MeGUI and ran the analysis and it detected the Source Type as Film, Top Field First, TIVTC
If that's the case, do I need to go back to DGIndex and set it to "Force Film"? or do I leave the settings the Avisynth Script Creator Analysis picked up?
Really confused on what to do next, hope you guys can advise me.
Many Thanks

Any "auto" analysis algorithm can make mistakes

Thanks for the reply, but ths info isn't very straight forward in my opinion, I'm quite new to this stuff. I tried making an .avs with the info they suggested and I tried loading it in virtualdub but I get an error about MPEG2Source not found, when I've put in the correct name of the .d2v file...

Okay, thanks, I already have DGIndex
I'll re-create the .d2v again using the latest DGIndex
I've put the DGDecode.dll in the avisynth/plugins folder as you instructed.
I've opened notepad and put the following in:-
MPEG2Source("Scene 1.d2v")
AssumeTFF()
SeparateFields()
I put AssumeTFF because the F5 analysis in DGIndex shows the video being Top Field First.
I then saved the script as an .avs and opened it in virtualdub by going to "run script" and it still comes up with MPEG2Source not found
Shall I try Avidemux? -

Thank you, I'll try the full path now and see if it makes any difference
Does it matter that I am using Virtualdub 64-bit, or not? -

I don't use MeGUI, but it's likely there's no contradiction. DGIndex tells you how it was encoded, and hard telecine (film with the telecine encoded into the video) as well as anything shot using video cameras gets encoded as interlaced 29.97fps (aka Video). MeGUI apparently is saying the ultimate source is film and it needs an IVTC to restore that progressive 23.976fps movie.
In addition to stepping through the fields looking for the telltale 323232 pattern of field repeats (assuming you made the D2V using 'Honor Pulldown Flags'), you can also open the script with no filtering at all, scroll to a place with movement, and then advance a frame at a time. If you see 3 progressive frames and 2 interlaced frames in every 5-frame cycle, it's hard telecine and a candidate for TIVTC. Such a very basic script might go something like:
LoadPlugin("C:\Path\To\DGDecode.dll")
LoadPlugin("C:\Path\To\TIVTC.dll")
MPEG2Source("C:\Path\To\Movie.d2v")
#TFM().TDecimate()
If it's hard telecine, remove the comment (the '#') and check that it's now 23.976fps and the interlacing is gone.Last edited by manono; 9th Mar 2012 at 16:15.
