Overlapped block motion compensation?
Indeed.
What the paper? I can't find.
That paper was on a Chinese server that is no longer available. Anyway I was wrong about the hands movement. It is addressed in a different paper, which uses optical flow: http://www.cs.berkeley.edu/~malik/paper … i-2010.pdf.
It obviously includes MVTools. I mean, which publications were used. Current papers (for example, Bai et al. 2012) say about hand movement, and this particular method uses OBMC (there are others, for TV-L1). So, how far is SVP technology?
deadman Smooth factor: 1:1
and deadman {num:1,den:1}
It's no placebo, but there is no interpolation either (SVP ratio is 1:1). What you have is frame rate synchronization, which results in a smooth playback at 24 fps. Which is better than 2:2:1:2:2:1... playback of 24 fps source at a 60 Hz. You see a frame drop every 1/24 s instead of 1/12 s, which results in a smoother playback.
Another problematic resolution: 718x436. As in case of 1916x796, causes full GPU load in accelerated mode.
Edit. I worked around it by adding this code to MSmoothFPS.avs before "input=last":
last.Width == 1916 ? eval(""" AddBorders(4,0,0, 0) """) : 0
last.Width == 718 ? eval(""" AddBorders(2,0,0, 0) """) : 0
Seems to help, which means the bug is certainly in SVP.
I'm not talking about high CPU load. See:
With a video of nonstandard dimensions: MPEG4 Video (H264) 1916x796 23.976fps, GPU acceleration consumes full GPU power and additional 23% CPU
I'm attaching screenshots so you could see what's going on.
Nvidia inspector shows VPU load around 30%, so hardware decoding works well for any resolution. Also SVP works for this movie (without GPU acceleration), using 60-80% CPU. There is no excessive CPU load, which might suggest decoding of h.264 in software. And I already have CUVID in LAV settings.
I made some samples with Freemake, all with height=800 and different width: 1912, 1908, 1900 all worked well. The only problematic sample was that of width=1916.
With GPU acceleration: around 40% on fullscreen, 20% in a window; without acceleration - 30% fullscreen, 10% window.
I just tried it, GPU is still 88%.
I first wanted to start a new thread but it seems my results are similar, except that my files are progressive.
SVP 3.1.4, consumes 10% more GPU and additional 10% CPU with GPU acceleration enabled, when playing such a movie file: MPEG4 Video (H264) 1920x800 23.976fps. With a video of nonstandard dimensions: MPEG4 Video (H264) 1916x796 23.976fps, GPU acceleration consumes full GPU power and additional 23% CPU (which results in a slide show).
There are no such issues for 720p videos.
My system specification is: CPU Intel E5700, 2 cores @ 3GHz, 4 GB DDR3 @ 800 MHz, GPU Nvidia 9800GT, PCI Express reported by Nvidia Inspector: PCI-E 2.0 x 16 @ x 16 1.1. SVP configuration:

First I want to express my full appreciation for SVP and its good results in motion interpolation - movies never looked so good and currently I hardly imagine watching them with lower framerate than that of my display.
I did some research on how SVP works and what are the best options. So, I find that 50 Hz refresh rate always results in a perfect animation, 60 Hz looks slightly unnatural and 72 Hz is "too smooth". It is worth noting that I'm a European, which means I grew up in a country with 50 Hz television. So my question is: do you, possible American or Japanese users (from countries with NTSC or 60 Hz PAL) feel with 50 Hz refresh rate? Is it better or worse than 60 Hz? Also, I'd like to ask other European users, do you find any difference between 50 and 60 Hz?
