HD picture stuttering

[admin_exported]

I have had my Panasonic BD30 now for a few weeks and generally the picutre is superb, however there is one slight annoyance that I cannot dial out on BD films. Slow pans across screen produce a slight stuttering/flickering of the picture or perhaps when someone walks across screen it is just not totally fluid. It is not major but is is decernable, making the motion less fluid than it should be. My TV is not full HD but I have tried switching between 720P, 1080i and automatic and spent some time adjusting the natural motion parameters on the Philips set.

Does anyone have any suggestions or perhaps experienced this problem themselves?

Sounds like a 24fps issue to me. Does your Philips support 24fps?

My understanding is that only a 1080p set can support the 24fps signal. My set which is the 32PF9731D can only supper 1080I or proabably more native at 720p because I think it is actually a 760 line set. With the TV set to automatic I would assume that the 24fps would not be selected anyway? Any thoughts?

There are several HD Ready sets - notably current ranges from Panasonic and Pioneer - that can support 24fps.

Doesn't look like your Philips is one of them, however - although only 18 months old, it's from a time when 24fps HD players weren't yet an option.

Sadly, that means it's not capable of handling the native 24fps of your Blu-ray discs - hence the signal's having to be converted to suit your set, which is resulting in judder in tricky scenes. No quick-fix solution, i'm afraid - short of upgrading your otherwise excellent set.

Thanks for your reply Clare and sorry for the poor spelling in my last post!

Although I see your point I believe that in the background the 24fps function is disabled and the signal would only output to a 1080p screen, surely therefore the TV set is not receiving this signal but the normal 25 fps and does not need to make any conversion? This would be the case would it not with older BD players where they were unable to produce 24fps signals anyway? The disc content does not force the output, it is the selections you choose when decoding those signals and subsequentally are sent to the screen, is it not?

I am sure that in the background menus on the BD30 you can make the correct selections which I am sure I have (but I will check again tonight). Perhaps there is another BD30 user who can verify this for us?

I have to add that the instruction manual with the BD30 is very badly laid out and although I have some understanding of the HD topic a novice is going to really struggle with the detail.

Yes, your player may be outputting 25fps and your TV accepting it - but it doesn't get round the face that the Blu-ray disc holds 24fps content.

So, whether the player or set is doing the conversion from 24fps to 25fps, conversion is taking place - extra frames/frame-viewing time are being added to make up the frame-rate difference, which can (in tricky scenes, such as panning shots) lead to judder.

O.K thanks for the further explanation Clare and Oh dear! I am disappointed now. I had not realised that this might cause a problem. I had just assumed that the conversion process would work o.k and I would just not benefit from being able to watch the 24fps format. I guess I have to consider myself another person bamboozled by the technology and product being offered early which is not up to spec and given what I paid for the Philips I do not see myself trading it in for a good few years yet.
