I'm new to JRiver. I have noticed that there are hiccups every so often. The sound remains 100% but the video loses a frame or something and blinks. BD5 and 9 backups are better than BD25 with HD audio. I have read that using Madvr helps but I can’t see how to use that option.

Twice while watching a BD25 movie the video started vibrating constanty. This seems to be related to another issue I have that may be more of a W7 problem. My problem since I upgraded to W7 64 my PDVD11 had a severe problem. When I either updated windows or update nearly anything or leave the computer connected to long. PDVD would become corrupted and freeze up, it would keep playing but I could neither stop nor close the program. I figured out that I can restore the OS from an image backup from a known working point. I figured out that if I want to do updates I could uninstall PDVD do the updates then re-install PDVD.

  Anyhow this why I started looking for a new program. After JRiver had the problem with the video shaking PDVD also became corrupted. As with PDVD when I installed the image backup of the Cdrive JRiver was also fixed. I don’t know if the vibrating video was enough stress to cause PDVD to become whacked or is this a W7 error and is affecting both JRiver and PDVD.

 I doubt anyone will be able to help me on this one but I figured I would post it. It’s to obscure of a problem.

It could be a few things, but if the PC is sound and has enough power (run Help--> Benchmarking) and post the results along with the make / model of your video card.

Also have a look at the wiki:
How to switch the display refresh rate to match the media FPS : http://wiki.jriver.com/index.php/Video_Playback_Options#Display_Settings then
How to keep it perfectly in sync : http://wiki.jriver.com/index.php/VideoClock

[Datman]

the screen shot is how I have it set up. I don't see any way to change it.The pull down I don't know which would be the best option or if making changes there would help playback. How do I use Madvr?

[Micromecca]

MadVR should already be in use as you have Red October HQ selected.

It could be a few things, but if the PC is sound and has enough power (run Help--> Benchmarking) and post the results along with the make / model of your video card.

I suggest providing the information that Jmone already requested so that folk can help you, also might be helpful to include the make/model of your Monitor or TV too, looks like it doesnt support 1080P@24/50/60 from your screenshot

[Datman]

I have an ATI 6770 graphics card and AMD FX 8150 processor. I believe I'm at the high end of things.

Another thing I'm trying to figure out how to best watch my archive of BD5 & 9 that are saved in folders. I like how once I figured out how to import the titles they show up but I don't see how to update if I add to the folder without clearing it and reimporting all the contents of the folder.


My monitor does 24 and 60 will not do 23

[mykillk]

Running your display at 30hz refresh rate while the movies are encoded at 23.976 fps will cause this kind of stutter.

I see that 23/24hz aren't available in your list, which should be fixable:

1) Install latest AMD graphics drivers. See if 23/24hz are available now.

2) If not, open the AMD Control Center

3) Go to My Digital Flat Panels -> Properties

4) Uncheck "Enable GPU Scaling". Hit Apply. I found this setting interfered with being able to select certain refresh rates. See if 23/24hz are available now in MC18.

5) If not, go to My Digital Flat Panels -> HDTV Support

6) Check the box for adding 1080p24 support. Hit Apply.

7) To confirm what refresh rates are available, go to Desktop Management -> Desktop Properties. I have the following refresh rates available: 23, 24, 29, 30, 50, 59, 60. Changing the refresh rate here is the easiest way to determine what refresh rates your display will support (hopefully all of them!). Of course you'll want to retain 60hz as your default refresh rate and let MC18 handle changing the refresh rate at the start of video playback.

After all of these, you should have, at a minium, support for 24hz refresh rate. This should be fine when using the VideoClock option to scale native blu-ray 23.976 frame rate to 24 fps (this is what a hardware blu-ray player would do). If you have 23hz refresh rate support (which is really 23.976hz refresh rate), and it's supported by your display, that's even better because you don't need to use VideoClock. The refresh rate matches as closely to the frame rate (or multiple of the frame rate) as possible, the ideal scenario.

Here's a cheat sheet on the best refresh rates (from best to worst) to use for a video's frame rate:

23.976 fps (most films): 23,24,60
24 fps (some films): 24,60
25 fps (PAL broadcast): 50,60
29.97 fps (NTSC broadcast): 59,60
30 fps (random): 60

[mykillk]

And if none of that works, I would definitely recommend 60 hz over 30 hz refresh rate for 24p content. 24p->60p pulldown is very advanced nowadays and should look just fine, without any noticeable stutter. 30hz refresh rate should be avoided entirely!!

EDIT: Something else I just remembered. Sometimes the 23/24hz options end up at the very, very bottom of the list.

[jmone]

There really is no way to avoid pull down judder if there is not an even multiple between the FPS and the Refresh Rate (well PAL does a speed down but you get a half tone audio shift)... anyway, I'd recommend the following refresh rates if you display device supports them + make sure you add Video Clock to keep it all perfectly in sync:
23.976 fps (most films): 23,24 and only 59, 60hz if you don't have 23 or 24hz
24 fps (some films): 23,24 and only 59, 60hz if you don't have 23 or 24hz
25 fps (PAL broadcast): 50 (never 60 if you can avoid it)
29.97 fps (NTSC broadcast): 59,60hz
30 fps (random): 59,60hz

Keep in mind that NTSC is just 30 or 60 * 1000/1001 so you get the very odd 29.97 / 59.94 which is on PC's represented as 29 / 59.  If you use the Video Clock feature it will smooth these small changes out.

[mykillk]

23.976 fps (most films): 23,24 and only 59, 60hz if you don't have 23 or 24hz
24 fps (some films): 23,24 and only 59, 60hz if you don't have 23 or 24hz
25 fps (PAL broadcast): 50 (never 60 if you can avoid it)
29.97 fps (NTSC broadcast): 59,60hz
30 fps (random): 59,60hz

I have to disagree with some of your ordering. Why use 23.976hz instead of 24hz for 24 fps sources? The last thing you want is have a refresh rate lower than the frame rate. Why use 59.94hz instead of 60hz for 30 fps sources? You wouldn't want to use 59.94hz for 24 fps sources either, that would mess up the 3:2 pulldown that is possible with 24p->60p due to them have a common multiple of 120

[InflatableMouse]

In my case, when I select 24hz for 23,975fps it jutters and I get more framedrops. When I select 23hz my tv automatically goes to 23,975, a perfect match.

Same with 29.97fps. If I select 60 it doesn't match up perfectly and I get framedrops. Selecting 59hz will pick 59.94. I never tried 30hz.

24hz with 23.976fps sources and 60hz with 29.97/59.94fps sources are exactly the kind of situations you'd want to use the VideoClock option. It will alter the playback speeds ever so slightly to turn those oddball framerates into nice even framerates. But as you say, if they are available to you, using 23hz and 59hz refresh rates are an even better option. VideoClock becomes unnecessary.

[jmone]

No video card does exactly 23.976, 24, 59.94 or 60 there is always a small drift and video clock will compensate for it.  What makes you think when you select 23.976 you really get that?  Many cards may show the options but still drive the same refresh rate.  The only way to tell is to try it.

[InflatableMouse]

Oke maybe "perfect" was not the right word. It does 23.97-something with an average framedrop every 8 days. No movie lasts for 8 days so for me that was close enough to call it "perfect"  .

When I select 24hz it does exactly 24hz and a frame drops every ~17 minutes. No movie I know of is less than 17 minutes so that's not perfect  .

I was simply trying to illustrate why 23hz could be a better choice than 24hz but I reckognize that not all TV's or videocards may support this the same way it works for me. My dad's TV/GPU doesn't do this, for instance.

[mykillk]

Modern AMD GPUs can do 23.976 and 59.94 as accurately as any other refresh rate and I think they are the only video cards that do. Heck, nVidia doesn't even have proper 0-255 RGB support...

[mykillk]

Back to the main post...

Something else I noticed on your screenshot. You don't even have 60hz listed. Are you using a custom driver for your monitor?

[jmone]

To support InflatableMouse point it really does not matter if your selection says 23.976 / 24 or 59.96 / 60 as you have to actually try them and see what your setup "prefers".  I have spent years trying to chase and tune refresh rates, front and back porches, scan length etc on many video platforms but thankfully we now have Video Clock that simply sorts out any of these minor mismatches as long as you are decoding the audio in MC.  I really hate NTSC.... as if movies are shot in 23.976 anyway.  They are (typically) shot in (multiples of) 24fps and just slowed down a tiny bit to make it compatible with the 1000/1001 NSTC broadcast spec.  For the vast majority of the (non NTSC) world this compromise is just irritating and I wish they were all just released in 24fps / 48fps etc (or better still 50 or 60fps).

So don't sweet it.... if you have the options, try both 23.976/24hz for BD material and 59.96/60hz for NTSC material and see if there is any difference...with video clock on.  If there is an issue pick the "good" variant then kick back and enjoy the content.

[Datman]

Thanks guys for all the input This is my set
http://shop.panasonic.com/shop/model/TC-P55GT30?t=specs and it does 24p

Running your display at 30hz refresh rate while the movies are encoded at 23.976 fps will cause this kind of stutter.

I can set it to 24hz.  23 hz is available but if I select it it just goes back to 24
I see that 23/24hz aren't available in your list, which should be fixable:

1) Install latest AMD graphics drivers. See if 23/24hz are available now.


I have 12-10 drivers. I tried 12-11 beta but had more issues with my other windows problem. This is still fustrating the W7 bugs with player software. I'm at the the point I should start over and do a fresh install it's a new computer this would be the 4th time I had at least some issues on all 3. Wht does windows never install the same way twice? W2000 pro was the last problem free version I have had. Some day there will be a better option.
2) If not, open the AMD Control Center

3) Go to My Digital Flat Panels -> Properties

4) Uncheck "Enable GPU Scaling". Hit Apply. I found this setting interfered with being able to select certain refresh rates. See if 23/24hz are available now in MC18.

Thanks for that tip.  With it checked, I only had '24' as an option and was getting stutter.  With it unchecked I have both 23 and 24 options and using 23 for 23.976 movies fixed the stutter.

[mykillk]

Datman, about setting 23hz refresh rate and it going back to 24hz in the Control Center. It does this for me too and has done that for as long as I can remember. But it actually does set it to 23.976hz refresh rate. You can confirm this by starting a 23.976 fps video in MC18, hitting ctrl+J to bring up the on-screen madvr interface. You will see there at the top what your refresh rate truly is. It won't be 23.976 exactly but it should be very very close. The Ctrl+J interface should be your go-to for diagnosing stuttering problems because it will show you exactly what your refresh rate is and the frame rate of the video you're watching and it also keeps track of the number of dropped and delayed frames.

[InflatableMouse]

About dropped frames, when you open the ctrl-j stats, theres always some dropped frames initially. Press ctrl-r to reset the counter and then check if its dropping frames.

[Datman]

I'm still tring to understand my options in display settings. In my 2nd post where I have the screenshot and the film 23.076 and 24 are set 1920x1080x32x30. Is that why some thought my monitor would not do 24hz?  Also am I limited in these options because JRiver is looking at my equipment room monitor not my extended monitor?

I am watching this thread with interest as I have been getting consistent stutter (only very subtle) but its there every now and again even with both hd and sd content. I am all for using videoclock but I like bitstreaming because I can see I'm getting HD audio on my receiver. If have MC do the decoding I assume it will send the audio as pcm which is theoretically the same as the bitstream but:

1) How can I be sure that windows wont interfere with the decoding somehow?
2) Do I need a decent dedicated Audio card?
3) How do I know its not just playing the dolby core?

I don't trust windows and the only way to be sure in the past was to bitstream.

[Datman]

thezone I have to use analog outs because I have a highend prepro that was pre-hdmi and has 12 years of a 20 year warranty left. I have used reclock just to check the audio output and it would say if the audio being passed was 16/24 bit or 48/96/192. You can uninstall after you check.

Hi Datman,

You wouldn't happen to have a Bryston by any chance? Nice bit of gear!

I don't need the pc to do the DA conversion just send it as pcm but how do I know its actually doing it?

[Datman]

Good guess. No one else has a 20 year warranty. I was almost ready replace it with a Marantz pre/pro I don’t remember the model but it had Audyssey . I brought it home to try and  it was cool but at the end of the day I just liked how the Bryston sounds over the 5.1 analog inputs. I have an Asus xonar hdav 1.3 deluxe audio card and it handles the analogs very well. I know I can send 2ch via spdif in 24/96 and the Bryston will read it as 96k. I can’t send any hdaudio that way. When I was thinking of upgrading everything I read said you can send full bandwidth pcm audio via hdmi. I can hear subtle improvements on some soundtracks analog over AC3/DTS spdif.

 
With PDVD 11 reclock would say 24bit for 24bit movies and 16 bit for 16bit movies. With TMT5 everything is 16 bit and JRiver is all 24bit, it must up convert 16 bit AC3 sources.

3 is the big one for me.  MC does a good job of picking the 'best' audio track available but it is not 100%.  Much easier to glance at the receiver than to fumble around with the remote and the MC onscreen menus to verify the track.

Add to that, you lose your receivers ability to do different things automatically with different formats.  My receiver does different decoding with stereo vs ProLogic vs DTS vs HD and I use that.

[Datman]

Twice while watching a BD25 movie the video started vibrating constanty.

Actually this has nothing to do with the W7 error I've been having. It's a bug with JRiver and when it starts I have to move my mouse and it goes away. If I move it over the top control bar or an option window it will start and as often as every 5-10 minutes it will start and moving the mouse stops it.

[JimH]

What else might be happening every 5-10 minutes on your machine?

[mykillk]

Yes, that's why people were thinking you didn't have 24 hz support. Whatever refresh rates you have available in the catalyst control center should also show up in the JRiver display list, but you only seem to have 29/30. If you have a dual monitor setup, that could be exactly what's causing this problem but I'm not sure how you can fix that since I don't have dual displays myself. I would assume the primary display is the one JRiver is going to use by default.

[Datman]

What else might be happening every 5-10 minutes on your machine?

TMT5 works perfect only it down samples to 16bit and someday cinavia may be a problem. As I said when it's playing PDVD 11 works perfect. The only program that has errors every 5-10 min is JRiver, but thanks for trying to help.

[Datman]

The stuttering is because of the secondary extended monitor, it plays smooth on the primary. Is there a way to force secondary monitor?


all I see is under tree and view but even after setting it to 2nd I still only have 29 & 30 display settings

[Datman]

I switched my main monitor and I got 24 and 23 options were available. And when I switched back it stayed. The more constant shuttering seemed to be gone but I still have a shimmer every so often.

In my experimenting when I set my theater monitor to main monitor it played pretty smooth.  When I set it to secondary and the 23 and 24 display setting were still engaged but the shimmer was not so good. The stutter was not present but I only watched it for a few minutes. My issue primarily is because I can’t force 2nd monitor and get the correct display settings.

[mykillk]

Try going into your MadVR settings, then to the rendering section, and under the general settings, check the boxes for the following options:

"Disable desktop composition" and
"only when media player is in fullscreen"

I did some quick research and it seems that Aero, a.k.a desktop composition, causes these kinds of stuttering issues on secondary monitors. From here:

http://forum.doom9.org/archive/index.php/t-152415.html

Something else you may want to look into is using a program called AutoFrequency to handle the refresh rate changes instead of allowing MC18 to handle it. I used it all the time when I was using mpc-hc as my video player and it worked great. I remember it allowed you to select which display it works with. The program is described here:

http://www.homecinema-hd.com/autofrequency_en.html

and available here:

http://www.homecinema-hd.com/down.php?file=autofrequency

ANOTHER idea you can play around with is using the "windows key + P" interface to disable your main display before watching a movie. That would make your secondary display the primary display. When you're done with your video, hit "Windows key + P" again and set it back to using both displays.

[mykillk]

Oh, and you'll want to enable fullscreen exclusive mode in MadVR as well when disabling desktop composition or else you'll get tons of ugly screen tearing.

[Datman]

thanks mykillk this looks like a big step in the right direction. However I still do not see how to get to the madvr settings. That machine is shutdown till later when I have some time. I might figure it out then.

[InflatableMouse]

thanks mykillk this looks like a big step in the right direction. However I still do not see how to get to the madvr settings. That machine is shutdown till later when I have some time. I might figure it out then.

Right click in a full screen when playing and choose directshow filters/madvr.

Or, press ctrl-3 to exit full screen and use the notification icon.

I found out a neat little trick. When you have more than one machine running MC (and have enabled RO on both) you can enable network on madvr and configure the notification icon to display when another machine is running it. You can then configure madvr from the other machine and observe the changes real time. Pretty neat .

[Datman]

I only have directshow filters. And now once I click on any of those or the DSP studio or the video play back settings the mouse no longer works and I have to close in task manager.

[InflatableMouse]

Looks like you're not using Madvr. Do you have Red October High Quality enabled in Tools/Options/Video?

[Datman]

Yes I even tried the reg red october no luck.

I uninstalled the program and reinstalled the latest version. That fixed what ever was going on with the mouse not working and a few other weird things going on.

as you can see from the screenshot the 23.976 and 24 settings have been remembered from the prior install but is I go to the pull down only the 29 & 30 options are available, as before.

If I move the mouse every minute or 2 the playback is perfect, no occasional shutter after a short period of time not moving the mouse the constant stuttering happens. This is completely unwatchable more violent motion that is fixed by moving the mouse. 

[Datman]

I downloaded and unzip madvr into the a folder and moved it into JRiver folder now madvr is being used. I had 2 audio dropouts while playing a video but that may not be a problem.

Thought the stuttering was fixed but as I was typing this it started again.

in the madvr screenshot you can see my 2 monitors, should i delete all the other ones?

In the 2nd screenshot I don't know for sure how to set it

[Datman]

Try going into your MadVR settings, then to the rendering section, and under the general settings, check the boxes for the following options:

"Disable desktop composition" and
"only when media player is in fullscreen"

.

This fixed it. I did have 1 audio dropout a few minutes after started playing.

Thanks for all the help. I didn't know I had to install madvr manually. I may be slower than the rest of the class but I get there!

[steelman1991]

You don't. JRiver comes with madVR preinstalled

[Datman]

You don't. JRiver comes with madVR preinstalled

I did not seem to in my case. As you can see by my posts it was not an option until I copied the folder with madvr over to JRiver program folder. Then it was there. I'm just glad it's working now.

[steelman1991]

Yes saw that from your postings - just wanted to remove your misunderstanding of the installation process and that ordinarily it isn't required and is part of the attraction of JRiver. What you will have to be careful of is further build changes, AFAIK these will overwrite/ride any manual installation.

Might be better further troubleshooting why it wasn't there as an option in the first place.

Glad its working for you now, though I can't help but think it will cause other issues further down the line - hope not.

I don't trust windows and the only way to be sure in the past was to bitstream.

I understand what you mean. I think for most bit-streaming is the way to go but I have read there are problems there too. Set it up both ways and listen and trust your ears, mind you that on 90% of movies you may not be able to tell the difference. I have a Chris Botti BD disc in 24/96 and when I was thinking about getting the Marantz I tested it every way I could bit-stream, PCM/hdmi with the Marantz and analog with the Bryston. Like I said with my audio card that is spec-ed to pass (if the application allows) up to 24/192 and decode dolby truehd and DTSMA I liked the analog better. If I had it to do over I would have bought the Marantz and saved 3k.

I just watched most of Chris Botti and all of Cowboys and Aliens JRiver sounds fantastc at least on par with PDVD11 and better than TMT5. Even though in the screenshot may look like it's only the core audio.

Glad its working for you now, though I can't help but think it will cause other issues further down the line - hope not.

 got it. Thanks for setting me strait The only thing I have to figure out is how to set up 29.97 fps movies. The Chris Botti did not play smooth audio was perfect. I'll worry about that in a new thread next year

You can do display switch in the madvr settings too, which might work better on a dual display setup. On the "display modes" section for your Panasonic TV (or whichever is the display that you want to watch your movies on), check the boxes that you had checked in your screenshot above. Then in the area for "list all display modes that madvr may switch to" use the following:

1080p23, 1080p24, 1080p59, 1080p60

Then go to the MC18 video settings and disable the option for "Enable automatic display setting changing"
