Hello,

I've got the following setup: Win 7 32bit, i7, ATI Radeon HD 5670, MC15, Sony 46 inch LCD TV capable of accepting 24p input (on screen display shows 1080p24 when I play Blu Ray from my Denon 4010 blu ray player).

I have some files, MKV and Blu Ray, that are encoded at 23.976p and 24p.  I want to output this to the TV with no frame rate adjustment.  I've tried right clicking while playing the files and selecting "Change Display Settings", but neither 23.976 or 24 fps are available.

In my ATI control panel, I could select the refresh rate there as either 23 or 24 Hz, but I would like to have it set to 50 Hz (I'm in PAL land) and change it from within MC when playing other frame rates.

Can anyone assist?  Thanks for considering,

Ben

More info here in the Wiki - http://wiki.jriver.com/index.php/Video_Playback_Customization and while reclock will be your friend you should also be able to tag files in MC so they switch your TV to 24hz.  You may need to add 24hz to CCC as an option so that MC can see it.  Other wise you can manually edit your Playback Info field to somthing like "(1:5)(15:DisplaySettings)(15:1920x1080x32x24)(9:CropEdges)(1:1)(12:CenterOffset)(3:0,0)(11:AspectRatio)(1:0)(11:ZoomPercent)(3:100)"

Thanks jmone, I forced 1080p24Hz as an option in CCC even though it had already showed up in the list of available refresh rates, made no difference, MC15 cannot see 24Hz.  The only way I can get 24Hz is to change my to 24Hz in CCC first, then it correctly plays 1080p24.  I noticed when I did this and right click>Change Display Settings while playing, that 24Hz still wasn't available, but none of the settings were "ticked", whereas previously 1920x1080x32x50 was ticked.  So I assume it was actually 24Hz but because this option was unavailable there was nothing to tick.

I've numbered questions for answering if you have the time:

1. With manually editing "Playback Info", the only field I want to change is the 24Hz playback, I want to keep all the other values as default, can I just enter one command for this or do I need to enter the whole string as you suggested?  Is there anywhere eg wiki, that explains what all the fields refer to so that I can set it the way I want?

2. With 23.976Hz files, how does Media Center speed this up to 24Hz?  No frames are duplicated are they?  Just existing frames played back at 24Hz?  Does this affect the pitch of the audio?

3. By "tagging" the files, do you mean right clicking while playing the files and selecting "Change Display Settings"?  Any way to tag them as a batch before playing, eg I could tag all my 24p material by selecting them all first, then one multiple file tag.

Also, I'm interested in ReClock, but have a few questions:
4. Why hasn't it been updated since 2005?  No need to?
5. Do you select ReClock as the audio decoder in MC15 for each file type?  eg for mkv in MC15 I have selected the FFDSHOW audio decoder, MPC-HC video decoder and EVR.  If I install ReClock, would I DEselect the FFDSHOW audio decoder and replace with ReClock?
6. Are ReClock and WASAPI compatible?  Or do I need to select "DirectSound" as the "Output Mode" in MC15 options?

Thanks, Ben

Thanks jmone, I will add 24Hz in CCC even though it shows up in the list of available refresh rates.

First of all I'm assuming that everthing in your playback chain supports 24hz (eg PC Video Card, Receiver, TV etc).  If so the 24Hz "should" show up under Right Click on play video --> Change Display Settings.  If it does not you may need to add it in CCC so that MC can see it.

With 23.976Hz files, how does Media Center speed this up to 24Hz?  No frames are duplicated are they?  Just existing frames played back at 24Hz?  Does this affect the pitch of the audio?

The PC will play these files back at whatever clock rate is set (note: you will never get either 24hz or 23.976hz as they are just not that accurate.  I get on my ATIHD5450 somehting like 24.005hz) and hence the frames will be played a little bit quicker (and while the pitch will be higher it is such a small difference you will not hear a thing.  It's note like the 4% 24-->25 PAL speed up).  As the video playback speed is set of the Audio Clock you will eventually get duplicated or dropped Video frames to keep the audio in sync.  The advantage of reclock is that it will swap this around so you resample the Audio to keep pace with the Video (unless you are bitstreaming).  Recolck also has the ability to report changing FPS and change the refresh rate of the Monitor (via a VBS script). 

By "tagging" the files, do you mean right clicking while playing the files and selecting "Change Display Settings"?  Any way to tag them as a batch before playing, eg I could tag all my 24p material by selecting them all first, then one multiple file tag.

Yes, while playing you can Right Click and change a bunch of Video Playback options including Crop Edges, Frame Rates etc.  These values are then stored in the "Playback Info field" that you can then manually edit or copy to other similar tracks.  Eg the string I gave you previously I've copied to other similar clips.

Also, I'm interested in ReClock, but have a few questions:
1. Why hasn't it been updated since 2005?  No need to?
2. Do you select ReClock as the audio decoder in MC15 for each file type?  eg for mkv in MC15 I have selected the FFDSHOW audio decoder, MPC-HC video decoder and EVR.  If I install ReClock, would I DEselect the FFDSHOW audio decoder and replace with ReClock?

1. Reclock is now updated by slysoft at http://forum.slysoft.com/forumdisplay.php?f=85 and is still free
2. In MC you select either Reclock as the Audio Renderer (or leave a system defaul and in the reclock settings you can set it to load as the default).  You still use FFDSHOW as your Audio Decoder

Good Luck

Thanks for quick reply Nathan...I was modifying my post as you replied, so I've still got a few questions if you have time...

1. Everything in my chain supports 24p, I forced 1080p24Hz as an option in CCC even though it had already showed up in the list of available refresh rates, made no difference, MC15 cannot see 24Hz.  The only way I can get 24Hz is to change my to 24Hz in CCC first, then it correctly plays 1080p24.  I noticed when I did this and right click>Change Display Settings while playing, that 24Hz still wasn't available, but none of the settings were "ticked", whereas previously 1920x1080x32x50 was ticked.  So I assume it was actually 24Hz but because this option was unavailable there was nothing to tick.

2. Are ReClock and WASAPI compatible?  Or do I need to select "DirectSound" as the "Output Mode" in MC?

3. With manually editing "Playback Info", the only field I want to change is the 24Hz playback, I want to keep all the other values as default, can I just enter one command for this or do I need to enter the whole string as you suggested?  Is there anywhere (I couldn't find it in the wiki), that explains what all the fields refer to so that I can set it the way I want?

Many thanks, Ben

[bpchia]

Also in the "Playback Info" tag, if I select a different frame rate, it adds it to that tag, but there are three lines of "Playback Info", it seems I can select one of the three, but if I try to delete one line, it deletes the whole field.

Is it OK just to paste "(1:1)(15:DisplaySettings)(15:1920x1080x32x24)" into the "Playback Info" tag of all files I want at 24p?  Will all the other values remain default?

Many thanks again,

Ben

Yaobing (one of the devs) may be better to look at why 1920x1080x32x24 is not being enumerated.

2. Are ReClock and WASAPI compatible?  Or do I need to select "DirectSound" as the "Output Mode" in MC?

If using reclock you select in MC either Default or Reclock as the renderer then in Reclock you select WASAPI or DirectSound etc.  I use WASAPI output over HDMI from Reclock for all my Video sound from MC and TMT for Blu-ray.

3. With manually editing "Playback Info", the only field I want to change is the 24Hz playback, I want to keep all the other values as default, can I just enter one command for this or do I need to enter the whole string as you suggested?  Is there anywhere (I couldn't find it in the wiki), that explains what all the fields refer to so that I can set it the way I want?

"(1:1)(15:DisplaySettings)(15:1920x1080x32x24)" should be fine and leave the other settings at default but I'm not sure if MC will change it to 24hz if this is not enemerated.  You will have to try.  One benefit of using these field is the the settings are changed prior to the Video being played, unlike reclock which actually monitors the frame rate as it is playing and switches the refresh rate to match (some video drivers / cards don't like changing during video playback but the ATI's seem fine).

[bpchia]

Thanks for your helpful replies jmone.

That's the thing, "(1:1)(15:DisplaySettings)(15:1920x1080x32x24)" worked, so don't know why it's not being enemerated...

[jmone]

bpchia - Your right, 24hz is gone from my system as well but Windows see this option fine (see pic).  As you said it still works, you just can't select it (but boy to you get a looooong list of all other possible combos but just not 24hz).

Yaobing - do you need any logs?

Thanks
Nathan

[Yaobing]

Do you get 24Hz from Display Options dialog window?

[jmone]

Hi Yaobing - I'm not sure as it does not specify the Frequency, just resolution and bit depth - here is what mine looks like.
Thanks
Nathan

I'm following this because I've only just gotten a TV capable of this, and I'll soon be playing around with these options.  Haven't tried anything yet though...

Heaps of playback options can be preset which is great for pre-configing how you want everthing to play - with handling my "pet hate" video format here http://wiki.jriver.com/index.php/Customisable_Video_Playback

Out of interest does that new TV of yours support 50hz (I know the documentation does not list it....but can you switch to it anyway?  The equipment sold in PAL lands supports 50, 60, and 24hz these days).

Silly me!  

I will have to do some testing tomorrow, although I am not sure if my video card is capable of this.  If not, I will have to rely on your log files.

[jmone]

No probs - let me what what (if) you need

[bpchia]

Hi, sorry I stopped checking this thread...but my tv does support 50, 60 and 24Hz.

I actually found I got more judder when setting the output to 24Hz than 50Hz, so something must be wrong here.

[bpchia]

I worked out why I was getting dropped frames using 24Hz for 23.976fps material. I should have selected 23Hz because for ATI cards 23Hz=23.976Hz. When I select 23Hz I get no dropped frames and my display says 1080p24. So I'm sorted! Still 23 & 24 not avail on the Change Display Settings list

[sunfire7]

guys check this tutorial: http://www.homecinema-hd.com/intro_en.html

Is to set up an htpc to play movies at the highest quality possible, is based on mpc-hc but would also work with MC15, (except the madVR part, but this will soon supported, I hope!)

I followed and I got no dropped frames, smooth video finally!
