I get jumpy playback of .mkv. It's not noticable 75% of the time, but any scene that has the camera sweeping a large panorama, for instance, it appears to skip slightly as the camera moves across the scene.


I have the combined community codec pack installed as well as the following hardware with all current drivers:


# CPU: Athlon X2 4850e ADH4850DOBOX 45W Brisbane 2.5GHz Socket AM2+

# MOTHERBOARD: GIGABYTE GA-MA78GM-S2H AMD 780G chipset microATX

# GRAPHICS: ATI Radeon HD 3200 (integrated in the motherboard chipset)


I have this problem both on my HTPC with Vista Ultimate x32 with all recent updates installed, and on my main computer with XP SP3.

What resolution and refresh rate are you using? Have you tried using mpc-hc built in decoder's?

 

[npeters]

I am using 720 for the projector. Projector is a SHarp DT-510. I'm unsure of the refresh rate. I think 65. Recommendations?


I don't know what mpc-hc built in decoders are. Please explain.

Can you do 24Hz?

 

[npeters]

It looks like all I can do is 50hz and 60hz.

 

[GooberedUp]

I don't think there is anything you can do about it then. But, I'm not very knowledgable about such things. There's most likely someone here that can give you a more complete answer.

You think this is solely a refresh rate issue?


Does a lower refresh rate equal smoother playback?

If it's true judder, then it is a refresh rate issue.


The wikipedia article explains it pretty well:

http://en.wikipedia.org/wiki/Telecine

 

[npeters]

The section on telecine judder does sound like my problem. I'll see if I can enable inverse telecine on my ati control panel.

 

[npeters]

Enabling inverse telecine did the trick. Thanks!

 

[internetman]

Where is this inverse telecine option in Ati control panel?

 

[stone604]

i would also like to know as well

 

[npeters]

I tried it on my Nvidia machine. Now I realize I have no option on the ATI machine, which is my HTPC machine.


Any more advice?

 

[AIA_SMALZ_11]

Where did you find this option to "enable" inverse telecine. i cannot find it anywhere in my ati catylist control panel. Can you let us know where it is?

 

[Bigbird999]

On ATI cards it is known as 3:2 pull down or similar. In CCC go to avivo settings and enable automatic deinterlacing and check pulldown detection. I belive the 4xxx cards have mor options to do this.
