it's called anamorphic video and is extremely common, just google and you'll find a ton of decent explanations

Kristen · 2009-03-05, 00:08

I'm not sure if this is the right place to ask, but it was the closest I could find.

How exactly can you get an AT-X transport stream audio in synch with the video? I analyzed it, and the decrypted AAC alone is 1 minute longer (26:30) than the one just playing back the stream (25:30). Is there something special about it that makes it do that? Or is there a guide someone on how to handle it? I tried researching, but I couldn't find anything about it anywhere...

neothe0ne · 2009-03-05, 01:47

You ran the TS through DGIndex and its length doesn't match the AAC audio?

(I've never really dealt with TS sources but that doesn't sound right)

jfs · 2009-03-05, 02:20

I'm guessing that the audio stream simply has too much data and you'll have to cut it at one of the ends or both.

Yep, that's exactly what I did.

jfs: The audio playback starts at 0:02, and then ends at 25:25 when I play it back. The .ts starts at 0:02, and ends at 24:55. By ends, I mean that the same sound heard on playback of the .ts at 24:55 is heard at 25:25. So it's not adding 30 seconds of junk data, surprisingly.

jfs · 2009-03-05, 16:42

That doesn't look like framerate problems. I was going to suggest audio sampelrate, but it wouldn't match with any common samplerates either (eg. 44100 vs. 48000). It's about 2% slowdown... well check the audio samplerate, but I don't have any further suggestions.

Can an avisynth script read video directly off a DVD?

Meltingice · 2009-04-05, 21:56

No, you need to rip it first with DVDDecrypter.

jfs · 2009-04-05, 22:03

Yes and no... if the DVD doesn't have CSS coding etc. you can index the VOB files on it directly with DVD2AVI or DGIndex, but you probably don't want to do that for performance reasons.
If it's because you don't have harddrive space to copy the files over to, you have a much bigger problem to solve first.

Nope, disk space isn't the issue. I want to be able to give the script to other people who have the DVD and let them run it without having to rip it. How serious are those performance reasons you speak of?

guest0815 · 2009-04-06, 01:04

Can a 1440x810 source somewhow be successfully deblocked with some cropping or resizing to a mod8 resolution of the same aspect ratio like 1280x720 or is there no hope for deblocking in avisynth

? Deblock() is doing *something* but every deblocker says to not crop or resize beforehand and I can't tell if it's smoothing in all the wrong places without knowing how a mod8 source would have looked like, so...

thanks

I don't know, haven't tried, only guessing.
But every way of accessing DVD video through Avisynth (that I know of) requires the source to be indexed beforehand using a separate program, meaning you can never get a fully one-click script. Also, the index files contain the full path and filename of the source VOB files, meaning that if someone who has their DVD drive with a different drive letter than you, they'd have to fix up the index file. (And needless to say, an index file is made for one specific DVD.)

Code:

DirectShowSource("D:\My documents\Anime\TV Series\_UnComplete\Rozen Maiden\Rozen Maiden Episode 09 (Dual).mkv",audio=true,fps=23.976,convertfps=true)
Textsub("D:\My documents\Anime\TV Series\_UnComplete\Rozen Maiden\[Vi-Ani] Rozen Maden (subtitles Eng & Vie chapters and fonts)\Vietnamese Subtittles\[Vi-Ani] Rozen Maiden Episode 09.ass")

logo = imagesource("D:\My documents\Anime\TV Series\_UnComplete\Rozen Maiden\Credit pics\Credit pic 01.png", pixel_type="RGB32", end=120)
logo = audiodub(logo, blankclip(last, length=120))

logo ++ last

There is some error, I can't insert picture before video start. When i play avs file by MPC, has error info "Splice: Video formats don't match, line 09"

How to can i fix this error?

martino · 2009-04-07, 09:08

I think you're trying to put together an RGB32 and YV12 clip. You should add ConverToYV12() for the logo... also set the framerate of the logo to be the same as of the main clip with AssumeFPS(last) or using ImageSource if it has an argument for it. Otherwise, are they of the same resolution?

logo = audiodub(logo, blankclip(last, length=120))

insertsign(last, logo, 0, 120)
#logo ++ last

Like this it run.
They are of the same resolution (880x480)
Avisynth says there is error in this line logo ++ last

Code:

logo = imagesource("D:\My documents\Anime\TV Series\_UnComplete\Rozen Maiden\Credit pics\Credit pic 01.png", pixel_type="RGB32", end=120).converttoyv12().assumefps(last)

Like this, logo ran but insertsign doesn't run

martino · 2009-04-07, 09:34

Uhmmm... what about my suggestion? Did it work or not?

for the lazy

Code:

DirectShowSource("D:\My documents\Anime\TV Series\_UnComplete\Rozen Maiden\Rozen Maiden Episode 09 (Dual).mkv",audio=true,fps=23.976,convertfps=true)
Textsub("D:\My documents\Anime\TV Series\_UnComplete\Rozen Maiden\[Vi-Ani] Rozen Maden (subtitles Eng & Vie chapters and fonts)\Vietnamese Subtittles\[Vi-Ani] Rozen Maiden Episode 09.ass")
LanczosResize(880,480) # Lanczos (Sharp)

logo = imagesource("D:\My documents\Anime\TV Series\_UnComplete\Rozen Maiden\Credit pics\Credit pic 01.png", pixel_type="RGB32", end=120, fps=23.976).ConvertToYV12()
logo = audiodub(logo, blankclip(last, length=120))

logo ++ last

EDIT: insertsign() takes a picture and not a clip.
