Have a question about usage/scaling:
If I set the following settings in Madvr, switch to mathing display mode - when media player goes fullscreen, restore original mode - when media player leaves fullscreen, and the list of display modes to 720p60,1080p60 only. Will madvr then play back 720p content at 720p resolution and 1080p content at 1080p resolution, while still upscaling everything below 720p to 720p?

Hi folks, dont know if this is correct thread, but:
a. How much does a 65x3 3D LUT takes approximately in Gb? How much takes 256x3 3D LUT in storage capacity? b. Does 3D LUT processing using madVR take significant CPU % when imported into madVR? Does it utilise significantly more CPU or the GPU? thanks Pluto

A 6-bit LUT (64x3) would be only 1.5MB And for good measure, a 10-bit LUT (1024x3) would be 6GB. They are not compressed.

…and to make things perfectly clear, the way you calculate this for an N-D LUT is:
Code:
((size)^N)*N*(output bit depth) = (size in bits) Last edited by e-t172; 19th September 2013 at 10:04. |

Nvidia vs AMD Radeon
Hi there,
At the moment I have an AMD Radeon HD 5500 videocard in my i7 pc, and no matter what settings/codec packs/combinations I use, I keep getting judder with panning scenes. Except when I use the smooth video project codec pack, but then playback really looks as smooth as a home video. Not really appealing. Are there any other options to get less judder? I can't seem to set my Samsung Syncmaster LCD Monitor to 24hz either. Would that be a limit of my videocard/drivers? I haven't tried something like "Powerstrip" yet, to add resolutions with custom Hz. And do you guys think there's any difference between Nvidia and AMD in general? How they/their drivers handle the Hz/fps issue? Then maybe I'd consider buying a reasonable priced Nvidia card. Hope someone can give me some options to try. Kind regards, Dennis |

the easiest thing to do is to enable smooth motion in the madvr settings.
if you are not satisfied, set a custom resolution with Custom Resolution Utility, http://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU, with a 72hz refresh rate and use reclock as your audio renderer. Last edited by mindbomb; 20th September 2013 at 22:04. |

I tried smooth motion. Unfortunately, it gives more of a slight constant "vibration" in the video's. Coincidently I stumbled upon the Custom resolution Utility, and tried to manually add 72 Hz, or 71.928, with the values: 1920, Front porch: 30, Sync width: 40, Back porch: 45 and 1080, Front porch: 3 lines, Synch width: 4 lines, Back porch: 5 lines. Then when I switch to this new resolution, my desktop is moved to the left, and stretched weird. Text is readable, but a little bit unsharp... Am I doing something wrong with the Utility? My screen shoud support up to 75, but don't know if it can handle 72 then? |

I have my main screen at 75 Hz, seems the smooth motion doesn't work properly at this rate. It does work at 60 Hz though (and on a connected TV), but it would be nice if it would function at 75 Hz.
Another major point about smooth motion, shouldn't this be available as an option for different screens? That is, if you have a couple of different screens available, some people may want it turned on if playing on one screen, but turned off if playing on another. At the moment the setting is universal and requires toggling. |

What should I write to "list all display modes madVR may switch to" field if I have a generic 17" LCD monitor that supports 60, 70, 72, 75 Hz frequencies?

I would suggest you try madVR in native resolution with highest possible refresh rate and SmoothMotion enabled or go for 72hz. If you really need to list different modes it goes like that: Code:
768p72, 768p75 Also madVR won't switch to a resolution/refresh rate unavailable to Windows. |

You should make sure that the monitor is not lying to you, and is not dropping/repeating frames when you request these refresh rates. I have yet to see a "generic 17" LCD monitor" that actually supports anything other than 60Hz. If you play a movie at 72Hz and it doesn't look smooth, your monitor is probably lying to you.

Thanks for the answer. I already have my monitor set to 72 Hz. But I see no difference in comparison to 60 Hz of the "preset mode". As long as I remember I have read once that all of these LCD frequencies aren't "fair", the frequency of a LCD monitor is always 60 Hz and all other frequencies are just emulated. But I may be wrong. I believe native resolution for 17" LCD is 1280x1024. If I don't use 25-to-24 fps conversion by ReClock, should I type Code:
1024p75 What about a generic CRT TV? I plan to connect it finally to my videocard. Will the following values be valid here: Code:
600p50,600p60 e-t172 Quote:

Code:
1024p60 What about smooth motion - should I enable it anyway?
