DVD2SVCD reports wrong movie length time ?

[Bob01605]

Twice in the past two weeks I have noticed that DVD2SVCD has reported a movie length time that was longer than the actual time of the movie. I am not talking about a few seconds or so but 10 minutes or so ? I recently encoded the movie "10 Things I Hate About You" - It said on the cover that it was a 97 minute movie but after loading into DVD2SVCD the time came up as 107 minutes - 10 minutes longer? The movie IS 97 minutes long. Yesterday I encoded "Jay and Silent Bob Strike Back". I load the movie into DVD2SVCD and it reports a movie length of 115 minutes. It says on the cover 104 minutes - The movie is 104 minutes long - a difference of 11 minutes ? Both encodes went well but here is the thing. Sometimes I make a decision on how I am going to encode based on the movie length. Decisions such as should I use 2 or 3 CD's or maybe drop the sound bitrate a little to gain some video bitrate OR in the case of "Jay and Silent Bob" should I go with two 90 min CD's or two 80 min CD's ??

Does anyone know why the program every now and then reports the wrong movie length time ?

some studios report the length of the film not including the credits. DVD2SVCD reads the DVD just as a DVD player would. I'm sure you'll find that if you add up all the chapters, including the credits, that you'll end up with what DVD2SVCD displays. If you'd like to check, you could always use other rippers and see what they say. Sometimes it varies slightly, but rarely much more than a couple seconds.

some programs to try: Smartripper, FairUse, Xmpeg(with special mism from Xmpeg homepage), DVD Decrypter.

I find that this happens about 40% of the time. I always check the length in WinDVD just to be safe. I have seen the time be off by as much as 5 minutes or more from what the IFO says.
While I am doing that I check to see how the chapters are setup and if the credits are a chapter of their own and if there is anything interesting in them. Some movies like Jay and Silent Bob there have a little surprise after the credits end. So in this case I will usually keep the credits.

Hey, all. 1-month old Dvd2svcd user here.

I've just seen this anomaly surface in ripping the Hercules DVD by Disney.

The movie is approximately 93 minutes long. DVD2SVCD (1.08 Build 1) sees it as approximately 106 minutes long. My DVD player software, PowerDVD, plays it at 93 minutes.

The problem, in this example, is that DVD2SVCD reports that track 32 (End Credits) is 17:53 in length. It's actually about 6 minutes in length.

The last track, track 33, is 0:00, and appears to be an end marker, since it zaps you to the end and out to the root menu in PowerDVD. I don't think it has any measurable length, so this figure seems correct. All of the other tracks that precede track 32 appear to have their length correctly interpreted/reported by DVD2SVCD as well.

So, I guess I'm wondering if this is some kind of bug and if we should bring it to the author's attention, perhaps.


Also, for rips that fill 2 discs (CDRs), I've been ripping/filling the discs individually by doing half of the chapters at a time to get a cleaner transition between discs. I'm going to go ahead and do that with Hercules here; I'm just wondering if disc 2 is going to be affected (bitrate-wise?) by this condition. Again, somewhat of a novice here, but I think I've read that there's some kind of calculation that takes place so that the encoding is done a such a way as to fill the medium. I'm guessing that I'll be okay here and that the calculation is based off of the characteristics of the actual ripped data, but feel free to comment if you can confirm or otherwise.

Thanks...

Alright, I'm back.

I just fired up SmartRipper 2.41 and it reports the correct length for track 32 at 6:04.17, so I'll go ahead and email this information to the author at dvd2svcd.bug@notrace.dk regarding this.

Just a heads up but I had some major synch problems when I split the rip the way you describe. I found that the disc with the first half of the chapters were fine but on the second the audio was way off. This happened with about five DVDs so I abandoned this method. Then again maybe I was just not approaching it properly.

I think I picked this up as a tip somewhere around here. I've done about 15 rips so far this way, and I admit I haven't really checked them thoroughly. I do spot check the BIN-CUEs with Daemon Tools and PowerDVD before I burn them though.

I will keep an eye out for this, though - thanks...
