Greetings all , newbie here but I'm learning slowly but surely.

Where I am running to an issue when I load my xxxx.d2v file into Moviestacker that I created using DVD2AVI 1.76, it reports the size as 96 minutes, 39 seconds.

However if I load up the source DVD in Power DVD, it reports the length as 118 minutes, 33 seconds. I also verified this length against the .mp2 file I ripped using HeadAC3he and it reports the same size.

This happen to me on two seperate DVDs.

What am I doing wrong? Do I need to manually set the movie length in Moviestacker?

Where this becomes a problem for me is when I feed in the movie length and average bit rate I got from Moviestacker into CQMatic my movies are going over the size limit since the it thinks the movie is shorter then it really is.

I appreciate any help anyone might be able to provide. Thanks

Did you set DVD2AVI to output in "FORCED FILM" mode ?

Dialhot,

No I did not have Force Film activated.

I turned that one, re ran it through DVD2AVI, and now Moviestacker reports the length as 120 min, 49 seconds.

My .mp2 stream from HeadAC3hE reports the length as 118 min, 33 seconds in Media Player 9.

I re checked Power DVD and it reports the length as 117 min, 42 seconds.

Is this variation normal, or am I still missing something?

This was a bug that MovieStacker inherited from FitCD. It was counting the flags from the D2V file in a wrong way. This was noticed especially with some hybrid material with repeated field. It's fixed now, and should report the exact frame number as AviSynth and VirtualDub.

Edit: BTW kwag, I think CalcuMatic suffers with the same bug. It reports the same wrong times as MovieStacker did.

It's just the way MovieStacker was conting the fags that was worng.
I was counting every number as frames, but you have to count it as fields.

In a D2V file the numbers (all the 0's 1's 2's & 3's) correspond to the rff & tff flags. If the number is 1 or 3 then it will have the repeat field flag. Count it in fields i.e. each 0 or 2 would be 2 fields and every 1 or 3 would be 3 fields. In the end you have frames = fields / 2. After that check the Field_Operation. If it is 1 (force film mode), frames = frames * 0.8.

That's it.

Happy Birthday
CalcuMatic 1.0.7 http://www.kvcd.net/CalcuMatic.exe

Fix: Should display same (correct!) time, if .d2v is either FILM or NTSC.

Have fun

Edit:
@muaddib,
Actually, the way I had written the frame counting routine, I just had to add something like this (in pseudo code ) :

Code:
  If Field_Operation = 0 And frame_rate = 29.97
   seconds = seconds * 1.25
  EndIf
