Anyone knows how to get rid of this strange vertical line?

[HitTheRoad]

Please take a look at this screen capture. There's a strange coloured, vertical line on the right side of the picture.



It doesn't show while playing the DVD on my TV. It pops up while playing it on my computer and it stays there all the time. Any idea how to get rid of this? Ripping the DVD doesn't help. It's still there on the VOB. Converting it to MPEG2 (using Avidemux2) doesn't help either.

Only converting it to another format, like mp4, makes the vertical line disappear. But... I prefer to watch my ripped DVD's in the original MPEG2 format.
Is there a way to get rid of the vertical line using a tool like Avidemux?

what software player are you using? Maybe it isn't really there (just a problem with the playback) ? Try another player, like smplayer, mpchc, vlc etc...

[HitTheRoad]

I tried different players. And I never had this problem before (I must have ripped and watched over 1000 DVD's).

Use the masking tool in avidemux to cover the black areas and re-encode as mpeg2.

[poisondeathray]

if it's really there on the video, you might not see it from overscan on the tv

if you don't want to re-encode, another option is to crop with the player during playback e.g. ffdshow

can you cut a small sample with mpg2cut and upload it here to examine ?

was this a retail dvd, and what did you use to decrypt ?

@ Johns0: The masking tool in Avidemux? Where can I find this?

@ poisondeathray: I used MacThe Ripper to rip the DVD. Never had any problems with this tool. The DVD is retail. I enclosed a small video sample.

The lines are on the DVD. You don't see them on TV because TVs overscan -- they hides the edges of the frame because there is often junk there.

You can mask or crop and reencode, you can use a player that simulates overscan, or you can use a player or codec that supports masking or cropping during playback.

Load the file in avidemux,select video output-mpeg2,then click on filter and choose blacken borders and input what needs to be black.

Sometimes you get an effect like that when the frame size is odd, the player adds some image to bring it up to a multiple of 4, 8 or whatever it expects. If it's black you don't notice.

Normally to convert VOB to MPEG2 I select 'Copy' and 'MPEG-PS'. But in that case I can't use any filter. Which MPEG2 should I select? MPEG-2 (avcodec), MPEG-2 (mpeg2enc) or MPEG-2 requant?

Because in that case you are simply taking the MPEG 2 video out of a VOB container and putting it in an MPG container. If you take a cake out of one box and put it in another box it's still exactly the same cake.

Which MPEG2 should I select? MPEG-2 (avcodec), MPEG-2 (mpeg2enc) or MPEG-2 requant?

You don't want to use requant because you can't filter with that either. I don't know which of the other two is the better encoder. Why don't you just try them both and see which turns out better.

None of the three encoders works for this VOB. I get a distorted picture. Strange...

The version of AviDemux I tested with (2.6.0, r7809) doesn't even have those choices -- only "MPEG2 (ff)", which I believe is ffmpeg. It had no problems with your video.

He's on a Mac. I think the Mac avidemux release cycle is about 1-2 years behind windows and linux releases

[HitTheRoad]

Jagabo, I'm using AviDemux 2.5. For the Mac that's the latest version.

[jagabo]

I don't know if the difference is 2.5 vs 2.6, or Mac vs Windows. It looks like there are some 2.6 builds for the Mac:
