you can't build a PC for video playback without a GPU. you don't have to set everthing to "maximum" or something like that you can easily use MadVR with a normal APU.
MadVR can be very very GPU intensive but this depends on the used setting. |

i was under the impression that onboard graphics is more than sufficient for video playback, but the little time spent reading up on madvr so far has proven me wrong. i know plenty about audio related matters but not so much video, hence this is doubly confusing for me
where do you think the law of diminishing returns kicks in with regards to settings used and GPU power? |

My Titan isn't good enough (only overclocked to ~1.1 GHz) to max luma doubling NNEDI3 for 720p24 to 1440p display. 128 neuron max, I run 64 neuron if I want to turn on other things like NNEDI3 chroma or ED dithering. My personal opinion is that madVR price/performance is at about the same place it is for video games, maybe a little below, which now that I think about it is almost scary. A 750 Ti or similar AMD card will give you everything you want (edit: Jinc3+AR, smooth motion, debanding) with headroom but any NNEDI3 would be too much for anything not SD. In my experience madVR can be set to work well with decent quality on an HD4000 or better, at least with a 1080p display. DXVA2 scaling on Intel might be good enough for you.

Is it possible to upscale to 1080p for somet video and 720p to another using profiles? I have some profiles set up but I'd like to upscale low res videos to 720p because it should take less power and I can ramp up the settings a little more with the saved gpu cycles

You can simply set your video player to a smaller window. Anything other then displaying the video smaller would involve a resize; defeating the point of turning up the settings getting it to 720p.

Also, am I correct in assuming that an upscale from 320p to 720p will use less processing power than 320p to 1080p (I.e. I can use 64 neurons vs 32).... |

madVR cannot change your screen's native resolution so unless you want a small picture in the center of your screen there is nothing to do. |

You can input the settings you want madVR to switch to in madVR settings under devices -> your screen name -> display modes, and enter your resolutions there. (ex: 720p60, 720p59, 720p30, 720p29). If its a tv screen then it may look good in both 1080 and 720, but if its a notebook or computer monitor if the screen may not look as clear (more blurry) at non-native resolution (depends on your screen quality and its scaling abilities). You'll have to test and see for yourself to see if you notice any drawbacks or not. If you never watch 1080p videos using madVR then you could go with just 720p (or i) entries, but if you do watch 1080p videos using madVR you should enter those with the 720 entries.

I'd rather ratchet up the settings and have it upscale to 720p than to have lesser settings (via profile) and upscaled to 1080p. Does that make sense? When I set my devices (monitor) in the settings I have: 1080p24, etc..., 720p24 but it always upscales to the monitor resolution in full screen. I'd like to upscale 720p content to 1080p and 320p to 720p. Not sure if that's possible. |

I don't think that's possible since profiles always go by file resolution, not some... transitional step. I also don't think the quality will change for the better with that behavior, if you're low on resources, just go with lower settings. The higher settings do show a difference, but frankly, with a 320p stream you don't have much quality to work with in the first place.
Also, letting madvr upscale to 1080p at lower settings is still better than having your monitor work at 720p (= let your monitor do the upscaling)

You will get best quality by using your display's native resolution. Do you have some performance issues going 320p->1080p which you don't get for 320p->720p or are you just against unnecessarily using power and generating noise/heat? |

i prefer directly see the results of the chroma upsampling to evaluate the quality. |

Hi,
I want to change the refresh rate of my display when playing a video and restore the default settings (1080p60) when leaving fullscreen. I was using smooth motion until now but it is taking a lot of ressources that I want to use to add debanding. My display refresh rate can be set between 50 and 75Hz. I've tried using the following settings in the display mode tab in madVR : 1080p60, 1080p59, 1080p50 However, the refresh rate always remains at 60Hz when playing 30, 24 or 23.9 fps videos. Is it normal ? How do madVR choose which display mode to use ? Thanks for your help.

PS: See if 72/75Hz aren't internally reclocked to 60Hz then Last edited by leeperry; 15th July 2014 at 21:40. |

EDIT : I've changed the settings with 1080p60 and 1080p59. It seems to work because the refresh rate is changed during playback but it's either 60Hz or 59.9Hz. Well whatever, I'll stay with 60Hz and without smooth motion (I have 0 dropped/delayed frames since I turned it off). Thanks for help
