The Holy Grail of XBMC for Mac OS X achieved? - 1080p 24Hz with no dropped frames

gmackenz Wrote:So I am curious how you were able to achieve this...I just got my Bravia a few weeks ago and am slowly learning my way through the dense HDTV thickets...

My KDL-46XBR4 is supposed to do 60Hz/120Hz (I guess its some sort of Sony pixydust magic to get 120Hz) but as I lack a bluray player (waiting for the bluray 2.0 hardware to come out this spring/summer) I have know real means to ascertain how visually attractive/ugly 120Hz video will appear.

So 1080/24p from a mac mini?

See my post from Yesterday, this is the info Elan used. So far I have only posted 24.0hz, I'll be posting other refresh rates over the next few days.

It seems that at 60hz the lip-sync is pretty accurate, but at 24p I seem to get a .2s delay on audio. I understand this could be specific to my display ( pioneer Kuro ) or receiver ( NAD ) , but I was curious if anyone has similar issues?

Yes, good spot. I've noticed the same with 24hz and downmixing to Analogue. It's fine with 60hz. I've yet to work out the display settings for 23.976Hz so I'll check it out at that rate.

I've noticed this too. The changes in 0.1.5 should have improved that, but there's still drift because of the 0.024Hz difference. The timings for 23.976 as well as for 47.962Hz (if such a mode exists), and the other NTSC/PAL timings would be great. Then we can optionally have XBMC pick the best available mode.

@DeanM3
How's it going? I my self using a Kuro LX-508 with a MBP, and was wondering if the later releases have improved your 24p playback? I using SwitchResX to set resolution to 23,976, but Im annoyed over the A/V sync-problem described here: http://forum.xbmc.org/showthread.php?tid=32561

It might help you to know your audio sync problem is not display specific as I have the same problem using switchresX to my bravia x3000, with the 23.976 settings.

I have had to revert back to the default apple 50 / 60hz settings as I have not found a solution to the audio drifting problem.

This is a shame as I would love to watch my sources in 24p.

Its an extereme example of high bitrate content but you might once in a while run into stuff like this in day to day usage. My 3.6ghtz OC'd Core Duo E8400 just about survives the ordeal and can playback the clip with a couple of dropped frames...

If it's the planet earth/bird sample my config handles it:
Quad-Core Mac Pro 2.8Ghz(2008), 8800GT, 10 gig ram.

Hiyas:

This might be a silly question but where are you all getting these 1080p/24 movie files? My Panny AX-200 accepts 1080p/24 signals and I'd like to test it out with my 1.8ghz C2D Mac Mini, but as far as I know Leopard can't play back BD or HD-DVD movie files...

What am I missing?

Thanks,

Hello:
I am a new macmini owner and so far is great.
The mini is hooked up to a 5080hd pioneer and it automatically detects 1360x768 60hz.
How can I get that it to play 1920x1080 24hz?

By the way I hope that I am making sense.

thanks

Doug
