Easy way to adapt subs for 1/2 D1 ?

[seewen]

Is there an easy way to convert the subs created by doif4u, so they are compatible with 1/2 D1 resolution (352x576 for PAL) ?
(Or maybe a way to tell Doif4u to create 352x574 subs directly)


The problem is Scenarist doesn't like subs with width=720, if the video's width is 352.

(I know how to create subs from scratch. But it should be faster just to transform the existing subs)

not required - the subs will show up fine with half-D1 res

"The problem is Scenarist doesn't like subs with width=720, if the video's width is 352."

what problem exactly...i've never had any problems with importing subs with half-D1 material

You are right.

I made a fault in the *.sst. Instead of
"Display_Area (0 2 352 574)"

I wrote

"Display_Area (0 2 352 576)"
(made the same error with 720)

And in fact there's no need to change the *.sst at all.
It's the same with "Display_Area (0 2 720 576)" (at least in the preview windows).

Thanks a lot.

some software dvd programs display subtitles wrongly with half-d1 material...but i believe its a software issue...it looks fine on stand-alone players

Yes, stand-alone display subs correctly.

Is it possible to tell Scenarist that the 352x576 video is 16:9 ?

My original video is 16:9, so I made a 16:9 1/2 D1 video with CCE.

DVD2AVI and ReStram detect it as 16:9, and it's written in RA script that the video is 16:9 (and of course it's look 16:9 or anamorphic).

But when importing the script in scenarist, scenarist show an "import error/wrong aspect ratio" and automatically change the aspect ratio to 4:3.

The same happend if I create a 16:9 project from scratch.
When I import the video, Scenarist detect the Stream as 4:3.

Maybe this place is not adequate for this question. But I ask here beccause you've already made 1/2 D1 DVD with scenarist.

The problem is that the AR is now wrong on a TV.

16:9 is non spec for half-D1 so Scenarist probably won't allow it. From memory I think DVD Maestro also makes the DVD 4:3 even if 16:9 is selected in the project.

But no matter, after compiling just use IFOEdit to change the flag to 16:9. I've done this, hell I even did it with automatic pan and scan as well =)

[seewen]

I didn't even thought about ifoedit. Good idea ;) .

EDIT: I compared the "standard" DVD with th 1/2 D1 (both made exactly the same way. Appart for the Avisynth script of course).

And in IFOedit, both stream (720x & 352x) have the same properties.
Both are 16:9 (but my standalone send the correct signal only with 720x).
Both are "720x576" too. So maybe the problem comes from here. I'll try to change this value into the correct one, and test again.

Thank a lot.

No...you have to make the 16:9 to 4:3 before you can make it half d1
add this to your script

LanczosResize(352,416,0,0,720,576)
AddBorders(0,80,0,80)

it'll make your video letterboxed half d-1...16:9 is not supported for half d-1 - hope this helps

[seewen]

If I transform it into 4:3, it works correctly. The aspect ratio is ok (all is perfect).
-------

I have a very last question. If I open the *.IFO of the 1/2 D1 video in IFOedit, I see that scenarist write that the resolution is "720x576".

And it's possible with IFOedit to change it to "352x576".

I tried both, and it didn't made any differences on my standalone.

Is it useful to change this value, or not ? (to avoid eventual compatibility issues with some standalones, for example ?)

no need bro...just leave everything as is...the 720x576 res is normal..even though it's half d-1

Ok. Thank you very much for your help.

The result is really good ;-). Much better than "standard" dvd. (Bitrate is ~2000).

Thanks again

16:9 half-D1 may be non-spec, but it does display correctly on at least some players (maybe most, I don't know). Guess you are just unlucky.

Then again, breaching dvd spec like this is not a good idea anyway, because a future DVD player may have difficulties even if your current one didn't.

very true - i say stay in the specs
