Reauther dark OEM DVD. Help! Please!

[p71rock]

I hope this is the right place to ask this...... I have a few (2) DVDs that I purchased and the Movie producers stated that they will not fix the problem. . Chef [DVD] Disk Three. [<-sorry I miss spelled the title and yes it is the BBC America title.]
{The main video is very dark 8) on home DVD players but with the aid of PowerDVD Vivid , I can make out most of the video.. }

Is there a way to extract the video chapters, brighten up the episodes, and then reauthor it with the original menus??

I have read the posting https://forum.videohelp.com/topic369681.html

Thanks! [All help is appreciated.]

*note that changing the brightness on the TV did not help.

It's lots of work, demux episodes using dvddecrypter or pgcdemux, reconvert the video with some filters(using for example avisynth and hcenc), remux back using muxman(I don't know how well it work with episodes though), add back menus using vobblanker....

edit: Or maybe it's possible with dvd rebuilder pro.

Have you tried adjust the brightness on your tv? ...

Demux title of dvd 1 to separate video / audio / subtitle streams ... Pgcdemux ... also extract chapter timings... ChapterXtractor (pgcdemux might also do this).

Grab avidemux and load the video stream ... output as dvd (mpeg2enc) and apply filter > Colors > contrast ... adjust brightness and contrast to taste and save as new file.

Use either muxman / rejig / ifoedit to reauthor title (in order of ease of use)

Use vobblanker to replace main title of dvd 1 with this new replacement title.

Test play ... ok... clear temp files generated and move on to dvd 2 title replacement.

p71rock - Please edit your post and fix your horrible misspelling of the name of this DVD so that others who might have it and might search our forums in the future will know what you are talking about. There's no such thing as "Cheif". I have no idea if you mean "Chef", the old BBC series, or an old American TV show called "The Chief", or maybe even something else.

Thanks for your help and sorry again about the title misspelling. I will try them out.

You could try using the Filter Editor in DVDRebuilder, the free version will do. Quick and dirty, but it may be adequate for your needs. I don't have DVDRebuilder Pro, I assume you can select filtering for individual titlesets as opposed to the entire DVD?

Options -> AVS Options -> Advanced (Expert) Options -> Filter Editor. Enter a script, save and exit. Rebuild the entire DVD.

Off the top of my head, a couple possible filters would be: Tweak, Levels.

Enter this to adjust the gamma:

Levels(0,1.3,255,0,255)
#Corrects gamma for display in a brighter environment. Second number from 1.0 to?

The above will brighten up the video noticeably. You could go higher, but at some point the result will look washed out. Default (no change) is 1.0.

*OR*

Enter this to increase brightness:

#Brighten
Tweak(hue=0,sat=1,bright=10,cont=1)

The third value is for brightness. Default is zero, 10 increases brightness modestly, but you could enter 20, 30, whatever, up to 255. Anything more than a modest increase would require other adjustments as well, IMO.

*OR* experiment with the script below, adjusting the values:

#Hue from -180.0 to +180.0. Positive toward red, negative toward green.
#Sat from 0.0 to 10.0, default 1.0. Above 1.0 to increase saturation.
#Bright from-255.0 to 255.0, default 0.0. Positive value increases brightness.
#Cont from 0.0 to 10.0, default 1.0. Positive value increases contrast.
Tweak(hue=0,sat=1,bright=0,cont=1)

Tweak allows you to make several adjustments at once, because obviously simply increasing gamma alone is less than ideal. More experimentation required, though, along with an idea of what will work. The values listed are defaults, you need to adjust them.

Each line with a # is ignored, it's just explanatory notes. The above are internal Avisynth filters. There are also a bunch of external filters available.

Just a suggestion, like I said, quick and dirty. [shrugs] :P

OK, the DVDRebuilder with the script lightening the picture worked great. but now I try and burn it in Nero and it gives me an error stating that the file structure is corrupted and nonburnable.. help!

Exact error: file 'vts_01_0.vob' is not referenced and should not be present

dvd-video files reallocation failed. the resulting dvd-video might be unplayable. do you want to continue?

[minidv2dvd]

it's nero that's a pos. use imgburn to burn discs.

[fritzi93]

Yeah, use ImgBurn. Personally, I'd open the DVDRB files first with DVDShrink. Shrink is quite sensitive as to correct structure, if after analysis it doesn't complain, all is well.

[p71rock]

Thanks for all your help.... It was hard to find for guide for Imgburn, but I did. :P Burning acording to the guide and now it not only works on my PCs but also in my DVD player.

You know, your television has brightness/contrast controls, too.
I remember how my saturation was turned down in the 1990s, because chroma noise was so awful on VHS tapes.
