Blu Ray Discs 1080/24p 1080/50p 1080/60p

What is the difference between these types, I have Blu ray discs that have each of these various types.

I can view this information on my blu ray player when I hit the display button.

Is one better than the other.

None is "better" than the other. Each one is there for a specific job.

1080p/60 is there for HD material sourced from film and American HD "video tape" sources.

1080p/50 is what we use for UK "video tape" sources.

1080p/24 is what's used for a conversion of film @ 24 frames per second to Blu-ray.

"video tape" means anything not shot on film. This could include digital capture movie cameras as used by Lucas for the later Star Wars films, and also material shot with HD Video cameras suc as concerts, TV programmes, sporting events etc

It depends on the source - 24 are content made on photographic film, 50 is European electronic source, and 60 American electronic source.

Thanks guys, so none give a better PQ, thats what I thought.

One thing I would like answering is judder.

My husband has season 1 of the universe which is 1080/24p but when there is panning from left to right and vice versa and sometimes up and down the picture seems to judder as the camera pans.

This never happens on any of the other BR's we have so it has nothing to do with a faulty BR player.

Is this something to do with the frame rate being 24 fps and is there a way to change a setting to stop this happening.

We have a Sony BDP360

There are any number of reasons for this. It could be because that is how it was filmed originally!

It might be a consequence of being 24fps, though if that is the original filmed frame rate I would be surprised. You are more likely to get that sort of effect as a result of changing frame rates. Especially where frames have to be dropped or new ones "invented" to fill in the gaps as it were.

Do you have any other 24fps disks for comparison? A lot of movies made originally for the cinema are directly transferred to Blu-Ray at 24fps.If they show the same effect then it may be the player or indeed the TV. if not then possibly it's this one disk or the way it has been mastered to disk that is at fault.

Unlikely there is anything you can do to the Sony player though to correct it however.

You should set your S360 to 1080P@ 24Hz (leave it on Auto) this way will give you best results. Some movies do judder when panning even when viewed at the cinema, however lot depends upon how good your panel is at at displaying 24Hz. Sony LCD's are not usually bad though

Check your TV will work at 24fps many don't so the film has to shown at a frame rate higher than 24fps using a pulldown tecnique to increase the frame rate. The result is exactly what's described visible artefacts when the camera is panned at a fairly high speed.

This sounds the most logical reason but my husband informed me that the extra feature length episode has no judder.

TV works with 24fps, its not the TV.

As I said previously. Compare it with another 24fps disk. If you don't get the same effect on another disk then it is likely to be something in the way this particular disk was either filmed originally or mastered onto disk.

If it is the way the disk was filmed or mastered then there isn't really a lot you can do about it.

If the tv is unable to display 24p then users should find the option is greyed out within the player setup menu as the HDMI connection will tell the player that 24p is not available
