I used to use SVP, but I gave up on it. Too many adjustments required for wonky source video, and half the time I couldn't get it to work without artifacts. I just put madVR on the highest recommended settings and get a beautiful picture, even though it's not quite as beautiful as SVP at its best.

This is "synced" to the refresh rate so, given that the refresh rate is never exactly 60 Hz and video is 24/1001 fps, the pattern of blends isn't actually 100%, 100%, 50% but more like 9.7%, 100%, 100%, 40.55% and continuously changing.

This generates lots of blended frames but given how humans see we only notice it as a slight blurring of the image, or a slight reduction in "sharpness", and much preferred to judder in my opinion.

Edit: Oh and the partial %'s are totally made up by me to illustrate the example. I have no idea what percentages madshi is actually using, it might be more complex than my simple 50% time = 50% blend.
SM is only need for 24fps media to me. Only there I get the wonky playback on each renderer/sync/etc config. 25fps/50hz, 30fps/60hz play smooth as butter everywhere. And the frame doubling is visible even on the 25/30/60fps media, its making it noticibly worse. 60fps looks like 30 fps without SM.

You forgot to tell us on what GPU and display combination? Because IME a slow responding LCD panel really makes FRC noticeably blurry.

just a stupid question. if my tv can do 24hz do i need enable smooth motion? when i put 1080p24 on display modes on madVR when i see a movie at 24fps (23.976) the screen change from 60hz to 24hz. 1080p24 movies are to be seen on tv with 60hz or 24hz? i suppose 24hz is the right option but i dont know much about this 24p stuff

do i still need use SM or SM is just to use when your TV dont do 24hz?

If your display can do 23.976/24 Hz natively (i.e. at integer multiple) then using that should be the best option. Smooth Motion is a helpful tool for those using PC monitors, which typically only support 60 Hz and thus cannot display 24/25/50 fps material without judder.

thanks for te reply.

i have a receiver that can decode HD sound. after i research a bit i found that i cant have a perfect 24p experience without any framedrop with reclock and at same time bitstream HD sound to my receiver.

so as far i can see i have only two options:

1) enable reclock and have perfect 24p experience but loose HD sound ( almost every movie i see have dts-hd sound )

2) dont use reclock and have some framedrops but gain dts-hd sound from receiver.

i found another option where i could download this "dtsdecoderdll.dll" so can lav filter decode HD sound, but i dont know if the HD sound decode from LAV have the same quality from HD sound decode from my denon receiver.

The only reason you need Reclock for a "perfect 24p experience" is if you're using PAL DVDs that need to be time-stretched from 25 fps to 24 fps. Otherwise, you just need to make sure your GPU is outputting 23.976p as closely as possible (tweakable with nVidia, not sure about AMD or Intel).

i have a nvidia gt630m. how can i tweak those 23.976? on movies madvr say display 23.972 Hz, that is the reason why i get some framedrops right?

edit: i found this stuff : http://www.anandtech.com/show/5969/zotac-geforce-gt-640-review-/5

the first SS basically is my display, 1 frame drop every 3minutes and display saying 23.972Hz. so i need to create a custom resolution as in second SS right? this will solve the problem, since 1 framedrop every 9h is more than perfect.

that custom resoltuion on 2nd SS will not be dangerous for my laptop or panasonic TV? i really want a true 24p playmode but dont want screw my laptop or TV in process

edit2: i found this too: http://yabb.jriver.com/interact/index.php?topic=62727.0;wap2

so basically i need to try both and see what comes near of 23,976Hz right?

"You can use the madVR OSD (press "Ctrl + J" to activate) to check how near you got to the optimal refresh rate, cause madVR shows a very exact measurement of the refresh rate."

At 23.971 Hz you'd get frame skips every 3 minutes or so (though you may not notice all of them depending on the scene being displayed). You need to create a custom resolution in the nVidia Control Panel to try to improve this, and it's essentially hit or miss as to what settings you need. I think madshi said that the refresh rate displayed by MadVR is approximate and not necessarily correct to 3 decimal places anyway so this causes more problems. I might be wrong on this though, hopefully he can clarify. Obviously the number of frame drops/repeats is accurate so you can play a whole film and see how many there are at the end to truly test.

No. If your TV can't handle a certain setting, it'll merely refuse to display an image or nVidia Control Panel will report that the display "rejected" the image. After all, it's very minor tweaks we're talking about, it's not like trying to force 50 Hz on a 60 Hz-only monitor. Laptop screens are generally crap and I've never tried custom refresh rates on them so can't really comment.

Are you sure it's not all the edges being cut off? Could be that overscan settings change when the resolution and refresh rate change. If not, try not to change the settings too much. A single number increase/decrease will likely have a relatively large effect. I know that increasing the total horizontal pixels on my TV creates dodgy lines everywhere so I steer clear of that setting.

As an example, with my GTS 250 the closest I can get (with the 15 minutes of effort I was willing to put in) is 23.97630 Hz, resulting in a frame repeat every 50 minutes. For this, I created a custom resolution with the default settings for 1080p/23.976 (which gave me 23.978xx Hz) but increased the total vertical pixels by one. I just checked and this measured refresh rate was shown by both MadVR and EVR so I assume it's accurate.

yes is that problem, edges being cut off. as soon i put any custom resolution, even if i choose 24hz and set the rest automatic the screen overscan and than i cant see the edges of windows.

dont know what i can do to correct this since when i try to resize the screen on nvidia options, say is unavailable for custom resolutions.

seem i will not have that perfect 24p experience soon.

after some research i read AMG gpu have a better 23.976 experience compared with nvidia.

Well don't choose 2 Hz for a start. Does the TV not have overscan settings?

sorri i edit my previous post. wasnt 2Hz but 24hz.

tv is a plasma panasonic g20 and have a 16:9 overscan option that is disable.

i forget to say my laptop is conect to a receiver denon 2309.

laptop-> receiver -> panasonic g20.

I have an AVR too but it's set to pass-through the video with no changes. Is yours set up the same way? Are you sure the overscan option doesn't enable itself when you apply the custom resolution?

my AVR doenst change anything on video but i connect my laptop directly to my panasonic tv and that overscan from custom resolution is the same.

next try i will check if my panasonic overscan turn on when i change to custom resolution. if not than i dont know what i can do more. maybe sell my laptop and buy a new one with AMD gou ( seem stupid since i sell my last laptop 2 weeks ago that had a hs5650 xD )

Its a S775 E7200 + nvidia gts450 and dell ips monitor and sony hx750. Notice that i took printscreen picture, not with camera. That doubled frame is wrongly 'rendered' by madvr, and it should not be in my opinion.

it will be the same quality... LAV + dtsdecoderdll.dll from arcsoft decodes DTS-HD MA correctly...

I noticed the same thing happening on my desktop with madVR, it was just harder to notice since the screen is a lot smaller, 24" vs 133". The above is a screenshot (print screen) with a portion of the lower border (resized to 500%).

i believe in you but i like the blue log of HD sound on my denon xD
