3D ghosting/ black bars on sides

Hi all,

I have an issue with 3D not centering correctly, so I’m getting ghosting and black bars on the sides?

what happens if you disable 3d on rasplex an enable it manually on your TV?

The plex client on the Samsung? Have not tried that yet, will let you know.

I havent played any 3d movies on my rasplex but on an LG plex client. The client or server doesnt know its a 3d movie, I just enable it from the tv telling it if its a SBS or TND movie and its always perfect

Most 3D movie formats are a single frame with both images inside. Rasplex/OpenPHT just presents that frame to the TV as is and the TV overlaps the images itself.

Ghosting side bars are almost always a problem with 3d editing on the movie itself and not OpenPHT. Most movies are filmed with a single camera and not a true dual 3d setup camera setup, so the effect is produced in post.

When you make a 2d image into a 3d image, you have to perform processing that shifts the perspective of the initial shot either left or right. But you only have so much 2d frame to work with. Editors need to have the shot look as close to orginally directed as possible, so often times they’ll not crop the individual frames to fit the screen perfectly. This creates the ghosting on either side as you describe.

There are also issues with re-edits released in BluRay. For example, you’ll see side bar flicker in the extended IMAX 3D release of Guardians of the Galaxy. This is because they added footage that was not included in the orginal IMAX theater release and had to use standard footage that did not match the IMAX frame size.

I could pen a long article on why there are 3d problems in releases, but I think you get the point.

Try watching Avatar in 3D. This film was shot with a dual camera setup so it would be correct the entire time and was actually processed for 2d in post.

As @benjaminwolf quoted, blackbars are usual on 3d movies as some horizontal information its usually lost for each eye in some convertions. Some 3d tvs let’s you modify the 3d effect which can make this effect worst when enhasing the depth.

I don’t think the problem its on the rasplex side, plus some 3d convertions are known for being really bad

Well, not a quote really. It comes from personal experience in the industry. :slight_smile:
