AutoGK and DVD Shrink

[rcktexas]

I imported a DVD, re-authored one title, clipped it (not compressed it) to about 10% in size using the Shrink editor and exported it in DVD format. I played the clip with WinDVD and the subtitle was presented on the screen. Then I imported the clip into AGK, selected the subtitle and previewed it. but the subtitle was not present.

I imported the full DVD into AutoGK, and previewed it. The subtitle was present. I converted the full DVD (XviD) using 30% quality for 1-pass and again with 1/3 CD for size for 2-pass. In both instances the subtitle was presented when I viewed it.

I did the same thing with the clip, and in each instance the subtitle was not present, even though the log claimed that the subtitle was processed.

I then used Shrink to create a clip slightly more than half the full title, and I foind the missing subtitle but it was way out of sync towards the end of the clip.

Somehow using Shrink to clip a title creates a problem for AGK. Or maybe I am doing something wrong.

Anyone have any idea what is going wrong?

Try clipping at chapter points...

Try clipping at chapter points...
I tried that, but still no subtitle.

Please try this clip from an earlier test:

It is two minutes long - 74 MB. There is only 1 subtitle in the clip. I converted it with 1-pass (Target Quality 30%). Or you can just run it thru Preview.

I just made a test clip (DVD Shrink - "Re-author") from "Lord of War" - and both the English and Spanish subtitles can be displayed.

In DVD Shrink, under the "Edit" dropdown menu, select "Preferences" - and make sure that you have NOT checked "Hide audio and subpicture streams of insignificant size" - and under the "Stream Selections" tab, make sure you've set "Sub-picture languages" to "All languages" and that there is NO checkmark next to, "Disable all subpicture except menus and forced streams".

I had not checked that one.

- and under the "Stream Selections" tab, make sure you've set "Sub-picture languages" to "All languages"

I had it set for English only.

and that there is NO checkmark next to, "Disable all subpicture except menus and forced streams".
I had not checked that one.

So the only thing I did differently was to check English Only subtitles. How is that going to cause a problem, I wonder.

I tested the new configuration and it did not help in Preview.

There is something going on with a pointer when Shrink clips a title and AGK or one of the utilities it calls is not picking up on it. Remember that with a longer clip I was able to see the subtitle but it was way out of sync. That would indicate a pointer problem.

The fact that the clip displays the subtitle from the VIDEO_TS directory tells me Shrink is doing things according to the rules. That makes me suspect AGK or one of the utilities it calls is not conforming to the rules.

It could be the title itself, since you are able to convert subtitles from Shrink edits.

I need to try a different DVD tomorrow.

I had it set for English only.Do try setting it to "ALL"...

Do try setting it to "ALL"...
Yes, I tried that, but still no subtitles.

I am going to try a different DVD. There may be something screwy with the one I have been using. I have run into screwy DVDs before that would exhibit audio sync problems when using a converter.

However it would seem that there is nothing wrong with the DVD I am using now because it displays the subtitle if I do not clip it, and it displays a delayed subtitle if I do not clip it very much.

In fact it displays the subtitle even after I run it thru Shrink and extract the main title but no clipping. It's only when I clip in Shrink that I run into a problem.

Did you have an opportunity to take a look at the clip I put on YouSendIt. Maybe you can look inside and see something I can't see. It's not very long - about 74MB.

Thanks.

I tried a different DVD and got the same results - no subtitles in the clip.

Should I take this problem to the (Auto) Gordian Knot Development forum?

[rcktexas]

I sent a PM to moderator "manono" asking if he could move this thread to the developers forum. He responded that since the developer moderates this forum. he will eventually see it here.

Then manono suggested something which solves part of the problem. The correspondence is below:

I think that the answer is in the clue you provided when you encoded half of it and found the subs showed up, but way, way out of synch. The answer, I think, is that the timestamps haven't been reset, and are for where the subs played in the original full movie. So, for example, if you cut a 10 minute clip from the movie, going from 1-10 minutes, the subs were processed, but they would be at the original place in the movie, maybe between the 50 and 60 minute mark.

You can confirm this by opening the IDX file in notepad and confirming what the timestamps say. If that's true, you'll have to reset the timestamps so that the first one starts when the first dialog is heard. You didn't say if you "burned" the subs into the video, or kept them as external subs. This will be much easier if the subs are external. To adjust the timestamps, use the VobSub Sub File Cutter utility that comes with VobSub. If you have the full GKnot installed, you can find it in the Subtitles Tab.

I use the AGK subtitle facility in the "burned in" mode but since I have WinDVD and it will accept external subtitles, I can run AGK in the external subtitle mode for test purposes.

Here is the IDX file for a clip that begins precisely 5:00:12 (min:sec:frames) from the beginning of the title and ends precisely at 7:00:12.

The AVI with this IDX file will not display subtitles in WinDVD, whereas the original exported clip from Shrink does display the English subtitle.

I changed the timestamp:

Guess what? It now works! The subtitles are visible and in the correct place.

You were absolutely right - the timestamps are not being reset correctly.

I will post this to the thread in hopes the developers will fix it.

Thanks for your assistance.
