SVCD2DVD fixed my sycn problem!?

[sn0wbl!nd]

I absolutely love this little piece of software.

Let me share with you a funny thing. kind of long to read by bare with me.

I had several hours of MPGs captures. I tried burning a 4gig mpg with sonic MyDVD. The vid and sound drifted out of sync (crap!) I tried using TMPEG to encode it, no luck, the VOB still drifted out of sync. I tried demux and remux with IFOEdit, made even worst. I tried demux with TMPEG and remux with VOBEdit's authoring function. That was no help either. I tried the trial version of ViaDVD and it too drifted out of sync (BTW, I loved the flowcharting in ViaDVD)

I felt my videocapture card was screwing up (well it actually is.) I was going to have to demux and force the sound to fit the video manually with sound editing software, which I dont' have, and then remux and cross my fingers.

Alas, I came across SVCD2DVD trial version. The limitations of the trial version said it was limited to a 2Gig file; however, it did my 4Gig file (go figure!?) But best of all, No sync problem!!!

I did five 4Gig MPGs without any sync problems, as opposed to the other software I used with the same MPGs. All I did was check the AC-3 audio button in the SETTINGS/PROCESS page instead of MPEG audio. I was compelled to immediately sign up with paypal and paid my contribution.

Now to business. I noticed a couple of issues.

1) When I insert chapter points with SVCD2DVD they work funny. When I move to the next chapter, it plays fine for a few seconds, then it skips back about 2 seconds and replays them, then plays just fine (until I skip to the next chapter). I doesn't bother me but I like to point it out.

2) sometimes, the movie stops and I have to press play or FFD and it continues fine. It does this where there are no title boundaries.

Suggestion to the author of SVCD2DVD
Could you check out ViaDVD’s flowcharding? For some reason it seems natural to use flowcharting to follow the navigation of the DVD menus (maybe I'm old school). Just a harmless suggestion.

Thank you. I hope you get rich and quit your 9 to 5 job.

Hi Snowblind - I liked the idea of DVD flowcharting so
I snagged a copy of ViaDVD. I spent 10-min with it
trying to find "flowcharting" in the help and tutorial including search - no joy.

Anyway,can it flowchart an existing DVD and/or
VIDEO_TS on hard drive or does this happen only when using it to author a DVD ?

TIA for any help,

In this case, it not called flowchartin. In "show biz" they call it storyboarding. However, the way ViaDVD uses it, it's more like flowcharding.

ViaDVD 4.13
Well, ViaDVD is not very user friendly in the sense that you can’t intuitively start working on it without reading the tutorial.

When it starts up, three windows pop up inside the main window (reminds me of Windows 3.1) The big white window (Storyboard view) is where you insert nodes and flowchart them. The Storyboard window will have a pic of a DVD player in it. Nodes are either the video streams, or the menus you add.

For example;
1) Click on Insert and choose Menu. A node will appear in the Storyboard window (Node0) Move it under the DVDplayer pic. Click on the DVDplayer pic and hold the mouse button while moving the pointer to the top of the menu node (Node0) and a line will connect them. Its now important that you edit Node0 properties (right-click) and assign it a background picture before you go on. The Background picture will appear in the lower left hand window (ViewWindow)

2) Click on Insert again and choose AVI..MOV Stream. An MPEG stream node will appear, in this case it will be named Node1. Do that again and you will get a third node (Node2). Move them below the menu node (Node0). Click on the color dots at the bottom of the menu node and hold the mouse button while dragging the pointer to the top of one of the MPEG Streams node (say Node1). Now, Node0 and Node1 will be connected by a line. Do that again to connect the menu node0 to the other MPEG Stream node (Node2) and they will be connected.

Now you have the menu node connected to the MPEG stream nodes and in the background picture window at the lower left, you can assign an exact spot on the picture where you want the Navigation Hot Spot to be and how big or small you want it.

You can position the Nodes in any logical order you want in the Storyboard and link them in any order you want. You can branch out of a menu node (after assigning its properties) the same way you would flow chart your way while writing software.

I like that I have a visual map of the actual paths the menus and submenus take as deep as I like all incorporated in the building process. Its cool, but, I can do that on a piece of paper.

I don’t think it will map out an existing DVD, just the projects which where created by it. I only used the trial version of it and dumped it as soon as I found SVCD2DVD. However, it would be really cool if there was a little utility which maps out a DVD’s structure… Humm….


BTW, can some one tell me why the sync problem was solved by SVCD2DVD simply by choosing AC-3 audio encoding? I swear, nothing worked until I did that.

Thank you.

Was it out of sync with MPA encoding?

Thanks Snowblind, for the tutorial. You should post it on their site, it would be a great help to their users.

What I gleaned from it, is that it will make a storyboard/flowchart for you, if
you make it first , not what I was hoping for.


Anyway, thanks for taking the time to more-than-fully answer my question.

As expected, the MPEGs played fine but when authored to VOBs the sounds got out of sync. As I mentioned before, I tried several methods to correct this (TMPEG, IFOedit, VBOedit, MyDVD, ViaDVD) and nothing worked. As a last resort I tried SVCD2DVD and with the AC-3 button checked and the VOBs had the sound in sync.

To answer, yes, with MPA they got out of sync just as expected.

Oh yeah, before I forget. With MPA option checked, PowerDVD had problems playing back the sound. I'm pretty sure I'm doing something wrong but for now, using AC-3 works bautifully for me.

That does suprise me: mpa has sync issue whereas ac3 does not... however at least you got something to work for you. Why does it work? Well the main point here is that the mpeg program stream is not demuxed.
