0.64a dgdecode 4:3 to 16:9

[jkavalon]

when encoding family guy season 1&2 dvd which is 4:3 the output dvd is 16:9, i believe the source of the problem is the dgdecode.dll as i have not had this problem before. if it could be anything else please let me know. thanks

Check your AVS options and make sure you don't have convert 4:3 to 16:9 checked.

Hi,

that problem was already discussed here (http://forum.doom9.org/showthread.php?s=&threadid=76721&highlight=family+guy).

You can solve that problem using ifoedit and change the flag 16:9 to 4:3.

[jkavalon]

it seems that the aspect ratio is 4:3. i opened the video_ts.ifo under the video manager information table, for aspect ratio it says 4:3, if this is the incorrect place to be looking, could you tell me exactly how to change the aspect ratio? thanks

[wmansir]

Check the IFO for the VTS itself. VTS_01_0.IFO for example.

[jkavalon]

checked all the vts sets, all show 4:3. is there anyway it could be that new dgdecode.dll?

[wmansir]

Not any way I can think of. DGDecode just decodes the picture from MPEG2 to uncompressed AVI to feed to your encoder. Aspect ratio is determined by MPEG2 flags in the video which are set by the encoder. As far as DGDecode is concerned there is no differece between 3:4 and 16:9 material.

Hi,(again:) )

I have the family guy encoded with dvd-Rb and the same problem happened to me.

To detect the error, open VTS_03_0.IFO (corresponds to the episodes), and in the main window, you should see the flag 16:9. All you need to do is change to 4:3.

See if that helps.

thanks for they help guys what you said worked, stupid me. i'm going to re-encode that disc again this time to ivtc it so i won't get those horizontal flutters. just want to run this by you...

Telecide()
Decimate(mode=1,threshold=50)

i entered that into the avs script editor for dvd-rb, that should work correct... as it is a hybrid film.

[wmansir]

You can't IVTC with DVD-RB, it will mess it up. It should recreate the hybrid structure like the original though.

[jkavalon]

so i should leave that original code in the avs editor?

[cmsoliveira]

Hi,

sorry for the dumb question, but...

help guys what you said worked,

what worked??

The tip i gave you is for the authored dvd...

And the 16:9 error only happened in the first dvd. The others went fine.

Cya

Edit: Forgot something... If you open the m2v files created by DVD-RB, you'll see that they have the right AR (aspect Ratio). The problem is only with the IFO files.

[jkavalon]

sorry bout that confusion... i edited that dar to 4:3... wasn't looking in the right spot, so it's showing as fullscreen now, just has that horizontal lines when there is too much motion due to it being a hybrid film.

I don't think that code is actual IVTC because Decimate(mode=1) doesn't actually change the framerate. So it should work, but I'm not postive.

[jkavalon]

alright i'll run the telecide parameter along with decimate... i'll let ya know tomorrow, hopefully it will work.

[jkavalon]

yea that didn't work, my video is a black screen with weird red bars at the bottom.

[cmsoliveira]

Hi,

sorry, i didn't understood the sentence...:rolleyes:

Do the lines show so much???

The encoding i've done, apart from the 16:9 problem, is, in the lack of better word, perfect.

all the options used were the dvd-rb defaults.

Sorry i can help more:(

[wmansir]

Did you add a line like:

LoadPlugin("c:\blah blah\Decomb511.dll")


?

You need to do that if you want to use the Telecine and Decomb functions because they are in the Decomb package.

[jkavalon]

omg i'm soooo stupid.... let me do that! thanks man... i'll encode it AGAIN tonight and let ya know how it went, what a stupid mistake!

[jkavalon]

i decided to preview one of the finished .m2v files during encoding, i'm still getting the same results after loading the decomb dll. i entered:

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\Decomb521.dll")

the decomb file is there, i'm still geting the jagged red lines at the bottom portion of the video.

[wmansir]

Try opening one of the .avs files in a media player and you should be able to read an error code.

[jkavalon]

the error reads as follows:

"Telecide: you must specify the order parameter (0=bff, 1=tff).
Refer to the user manual for how to set it properly.
An incorrect setting will result in incorrect decombing.
(D:\TEMP\D2VAVS\V03000000001001.AVS, line 9)

the avs file reads as follows:

#------------------
# AVS File Created by DVD Rebuilder
# VOBID:01, CELLID:01
#------------------
LoadPlugin("C:\Program Files\DVD Rebuilder\DGDecode.dll")
mpeg2source("D:\TEMP\D2VAVS\V03.D2V",idct=7)
trim(0,1768)
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\Decomb521.dll")
Telecide()
Decimate(mode=1,threshold=50)
ConvertToYUY2()

[wmansir]

I forgot about that. The new versions require you to set the field order. You might want to use the previous version (v4.10), which can be downloaded from Neuron2's page: http://www.neuron2.net/decomb/decombnew.html

The old version doesn't need to know the field order, but is slower because it takes time detecting it. There are also other improvements to v5 described in the documentation, but v4 is still very good.

EDIT: I recommend this for DVD-RB because the field order may not be the same for all cells on the DVD.

[jkavalon]

alright i threw version 4 of the decomb dll in there, re-doing the prepare stage, i'll let you know how things fly in a few minutes, thanks so much for your help.

[jkavalon]

alright! for now it's working i'll let you know how it looks tomorrow when the encode is done, thank you so much.
