|
 |
Hey all,
I have a question, I have a panasonic P46G10 Full HD TV, but when I play a movie and there is a scene where the camera slowely goes horizontal or vertical, the image is shaky, specially when its HD content.
The TV can show 24P content, but what is this, I's all the same, its shaky!!!
And specially, what can I do about it?

How are you playing your content? Also, can you provide more information on the content itself, or does it occur on all content?

It sounds like you're experiencing tearing which is fairly normal on some LCD's primarily.
What you need to do is to enable vertical sync or the equivalent. Some mediaplayers comes with this built into them, VLC, MPCHC, XBMC are some examples. Don't know about Xtreamer but look for some option called Vertical Sync, Anti-Tearing or something similar.

I have the same "problem" with watching HD content on the PC but I didnt mind fixing it cause I thought thats exactly what 24p is supposed to do. My LCD is rather old, not fullHD and ofc no 24p. Its especially noticable on documentaries like Planet Earth - they got alot of slow, panoramic camera movement often recorded by aircraft. And then the picture is vibrating just like the OP says.

For PC there is ReClock that can help fix some of the jerkiness.

if it isn't tearing related...
when you output the video from your computer, do you by any chance have interlacing enabled?
or if deinterlacing is enabled on the tv or if it is se to expect interlaced content?
cos it's progressive content so interlacing should be disabled on BOTH
if other or both attempt interlaced transfer and they can't agree on what the field order is, they might view the frames out of order
like 13246587... and so on

Upgrade your PC, a 386 cant handle HD

I'd try the tearing test of MPC-HC to make sure that your content is played back right.
The running line should run very smooth and without tearing

It's nothing to do with my pc, its just a blurayproblem I guess, somthing with 60HZ conversion to 24P or something I read elsewhere. The problem is; how bigger your TV is, how more you notice it. So on my 46inck its verry present! Than you buy one of the best TV's there is whithout pioneer's kuro... damn! And with a normal DVD its fine!! WTF?!!!!

AFAIK the G10 supports 24p playback @48 Hz i just read. And if thats true and your problem is related to 60Hz than its definitely your pc!
Check your settings! For ATI cards you need to set the refreshrate to 23Hz and for nvidia similar, maybe for nvidia it actually says 23,976Hz

But I use the xtreamer technology to stream it on my TV (look here: http://www.xtreamer.net/xtreamer/overview.aspx ), so my graphics card has nothing to do with it. The Xtreamer is connected to the TV and is connected to the home network. So my PC is only used as storage.

good point...
Does it shake in the same direction as the picture pans? ie. seemingly up&down when it moves up for example ?
Try closing one eye and squinting your other and see wether the movie is smooth then
