24fps playback

[tke743]

All, sorry if this is redundant but I’ve done my best to search for this one and do not have any answers.

How do I enable 24fps (for both 1080p and 480p) on my extender?
Can it be set in the native resolution switching?
Can it be set independently of resolution so that I can turn it on and off?

I’m the proud owner of 2 HD-100’s and soon to be owner of 2 HD-200’s too. I’ve backed up much of my DVD collection in native rate x264 video’s for ease of access. The 30fps videos look perfect, but the 24fps ones look like the bad 3:2 pull-down video of the past on the extenders

Sorry, some information on my system
Server is AMD Phenom quad core with 4GB ram and 3TB hard drive space running XP-PRO
Network is gigabit lan, so I assume this is not a server or network issue

Check out this post from the extender faq: http://forums.sagetv.com/forums/show...693#post252693.

I customized for 720p24 and 1080p24. 720p24 did not play back on my tv but I think this an issue with my tv. I think it only supports 24fps playback at 1080p. 1080p24 played back just fine.

You need to add a line to your properties file for the client in the sagetv install directory ( \sagetv\clients ).

The line for 1080p24 over hdmi is:
extender_resolution_extra_modes=1920x1080p@24|standard\=HDMI_1080p24


in my limited testing it did not switch with native resolution switching (havent investigated this too much). I had to use the "Video Out" remote button to switch to the 24fps playback. I wrote an stvi to show the currently output resolution on the timebar (for SageMC 6.3.8a, SageTV 6.5.4). If you are interested let me know and I can upload it.

I found no way to set the 24fps independent of the resolution. Not really a big deal with switching it with the "Video Out"

I am interested in this!

My TV is the Sony KDS-55A3000 and it does the same thing. 720p@24fps does not work. In fact, it sort-of crashes the extender. I have to pull the plug to reboot it. This tells me it ain't our TVs.

I wrote an email to Sage to see if it can be supported. I suggest others do the same if it's technically possible to put it on the roadmap.

I'm not so sure. I have the Pioneer PRO-111FD and I checked the manual and it says nothing about 720p24. It explicitly supports 480i60, 480p60, 720p60, 1080i60, 1080p60, and 1080p24. This leads me to believe it is the TV and not the extender.

In fact, it sort-of crashes the extender. I have to pull the plug to reboot it.

This could also be a syncing issue between the extender and TV perhaps? And not necessarily the fault of the extender... (but rebooting the extender is easiest way to fix it...)

When I tested 720p24 I did not have to reboot the extender. If I remember correctly I was able to use the video out remote button and cycle through back to a working resolution.

I checked the manual for your tv too and the only time a fps is specified is for 1080p24... to me this leads me to believe that your tv also doesnt support 720p24.

I don't think that 720p24 is a resolution and framerate combination that any display device would accept via HDMI.

For 720p24 mkvs the only way to show them at the correct framerate is to use 1080p24 I am affraid.

It's too bad there is not a way to get native output switching working conditionally. (or is there?)

My Sony TV may not be the best scaler/deinterlacer in the world, but its better than the HD200. I'll have to set it for 1080p and try that though.

[stanger89]

Yeah, I've never seen a TV that supports 720p @ 24Hz. 24Hz is usually only supported @ 1080p.

What do you mean "conditionally"?

Not sure myself! I'm writing before I think.....

Somehow on 720p@24 videos only, forgo native output switching and have the extender upconvert those videos only to 1080p to get 24fps support?

Of course, it's still a 720p video. 'Not sure if that's even possible.

To not put words in Valnars mouth.... but I think he means this:

If the video is X set the output resolution as Y. And have a table matching X and Y.

This way one could say if the video is 720p24 the extender should display it as 1080p24 (or 720p60... my preference is to let the TV do the scaling). There would be a table with all the different combination of resolutions/framerates (with wildcards) and what the output resolution should be. Basically making he native output resolution switching feature MUCH more powerful.

I'm not sure if this can be done in the STV or if has to be done in the HD100/200 firmware. My guess is you can accomplish it in either but would be much more robust if done in firmware

That's pretty much what happens, Sage will only switch to the "native" resolution if that resolution is enabled/configured. If not, it switches to the default/highest resolution available.

I am not home to try this.... but then are you saying I should disable 720p support from the configuration menu and all my 720p video will go up to 1080p? Would 1080p@24 work in such a circumstance on a 720p@24 video?

[stanger89]

It should play at 1080p yes, I'm not sure if the extender matches timings yet though (24-24, etc).

In my experience it does not. It matches only resolution. My 1080p24 files switched to 1080p60 output.

Right... but then does switching through the custom extender_resolution_extra_modes bring you to a viable 1080p24 output? If it does, then we have a partial solution. However, it'll still suck to disable 720p altogether, because then I have to rely on the HD200's scaling for 720p30 and 720p60 files. But I suppose that is better than showing 24p as 60.

So does it work?

Yes. You can always use the "video out" button on the remote to cycle through all the output modes. So you can leave 720p60 enabled and when you are viewing a 720p24 video you can manual use the video out to switch to 1080p24.

But I suppose that is better than showing 24p as 60.

Im not so sure. I think my preference to display 24p as 60p and let the TV do the scaling. But would need to test it and see which is a more pleasing picture. The 3:2 pulldown to convert 24p to 30p is fairly straight forward to do... far more easier (from a computing standpoint) than converting 720p to 1080p.

I wrote an STVi to choose the output resolution from a popup menu during playback(replaces the default "Video Out" behavior during playback. It works much better than using the "Video Out" button to randomly switch through the output resolutions. It is currently only for the default STVi.
