Hey guys, am having some what of an issue with my blu ray player and LCD TV.  There is a setting within the player menu for 24p which when turned on, seems to be every so often causing a judder on the picture.  It's usually evident on panning shots in bright light.

Was watching Titanic with one of the girlfriends and it was very evident on panning shots of the ship there was cleary juddering, going on which was really starting to piss me off.  I switched it off and it does appear to fix it, but the picture seems different (as in worse) somehow, when its switched off.  Or perhaps I am imagining that.  I dont see how it effects the picture, I thought it was to do with frame rates but it does appear that way and I was wondering if anyone knew why this is happening.  It's not a MAJOR problem, like I said switching it off seems to solve it but am interested as to why it is happening.

While am here, I may aswell ask this aswell.  When am messing around with settings (on the player), the TV keeps re outputting the signal.  As in, if I am watching a 1080P Blu ray, if I go to the players menu, I get a message ''searching for input'' then if I go to the settings the same message comes up again.  It takes me quite a while to go fromm watching a film to making a change in the settings, which again, isnt the end of the world but its anoying :\  I am assuming the menu's arent 1080P so that would explain the searching when I go from a movie to the main menu as it would be reoutputting to say 720, but why does it then need to re-output to 720 AGAIN when I go into settings?  .The player is set to automatic, perhaps I should force it to always 1080P?

EDIT:  One last thing.  The player doesnt automatically switch the TV to its input when I switch it on (but my old dvd player did).  I have to cycle through the source's (about 5-6 times) to get to the one am looking for (HDMI3) and then I get my picture.  How do you get it to automatically get there?  I read in the manual something about HDAVI that apparantly is what I need but it doesnt tell you how to do it :\

If anyone can understand those rambling it be appreciated   Cheers

Martyn

If the dvd of Titanic you were watching was natively 30p (or 30i or anything but 24p), then it would cause the skipping. You're asking your dvd player to play 24 frames instead of 30 per second and that causes the stuttering.

And that's the only question I know I can help with sorry.

so 24p means 24 frames per second? I did not know that

24p = 24 progressive frames per second. As compared to 30p or 30i (30 interlaced frames per second). Interlaced video splits a frame into two fields, and then pastes them together. I think.

While scouring wikipedia, I found some disadvantages to 24p that sound like your problem: http://en.wikipedia.org/wiki/24p#Disadvantages_of_24p

so 30p is better more FPS so then I guess 60p would look amazing, so why aren't movies shot in 60 FPS

Because it takes up more film/space. Think about it, you'd need twice as many reels or tapes.

But it really does look amazing. If you ever watch a frag video in 50+ fps, it looks like you are actually playing the game. Everything is so smooth.

It did say something in the manual about some content would not support the 24p and cause quote 'problems' that bit you explained aimless makes sense to me about the interlacing.  Will just leave it off

That was the main question I wanted to know the other two are really just niggles, thanks mate

Unless it's not that smooth for your game, in which case it looks simply amazing.

It's also possible that you don't need the 24p setting turned on because it could be conflicting with the film's 24p (though I doubt it).

P.S.
24p = 24 frames per second progressive (it's what speed films are filmed at and is more cinematic and realistic)
30i = 30 fps interlaced
30p = 30 fps progressive.
The 30's are terrible because it looks like your shitty home video you took on vacation with your shitty camcorder.

This contradicts what aimless and GR34 said... i thought more fps = better and smoother?

Who is right?

The higher the FPS "Frames Per Second" the better. Gamers strive to get higher FPS by buying better video cards. If a film is filmed at 60FPS rather than 30FPS it will look better because it will be more smooth. This is because the higher the FPS the more content you can get in your film. If you have an action scene where there is FAST movement "like a car chase", you dont want to film at a low Frame rate because the screen will start skipping. But, the higher Frame Rate you film at, the more space it takes up.

Most movies are filmed at 30FPS. I realy dont know where you get that 24FPS is more realistic because it simply isnt "yes i realize that a lot of the production movies are filmed at 24FPS".

What 1080"P" is.

The P stands for Progressive scanning. This means that all the lines of the movie are drawn at the same time.

What 1080"I" is.

The I stands for Interlaced Scanning. This means that the monitor displays either the odd lines or the even lines at one time. It alternates between them at a fast rate "even,odd,even,odd etc".
