Very high CPU with 3.1.4 in 1080p

Update to above. This is only happening on a few 1080p videos, not all. I get an OSD message about high CPU usage, and to try adjusting the filter settings. What should I be adjusting?

Nothing is changed in 3.1.4 concerning performance so it should be something in that videos.

a few 1080p videos, not all

what kind of videos, why there're different?

Here's Mediainfo for one of the files:

You not need for SVP for such type of video. 29.97 fps after deinterlacing become 59.94 fps.
Use DXVA for this purpose or if you have NVIDIA card then you can use LAV CUVID decoder with HW deinterlacing.

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:

I just tried it, GPU is still 88%.

With GPU acceleration: around 40% on fullscreen, 20% in a window; without acceleration - 30% fullscreen, 10% window.

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.

I'm not talking about high CPU load. See:

I'm attaching screenshots so you could see what's going on.

Thanks, that's cool  I've to make some investigations...

Another problematic resolution: 718x436
Thank you again.

AddBorders(4,0,0, 0)
It is not good solution for frame interpolation task. Thin black line at the frame border causes annoying frame-borders artifacts when panning and zooming.

mult=16
crop(0,0,int(width/mult)*mult,int(height/mult)*mult)

And ajust mult value. It can be 8, 16, 32.

2. Expand framesize in ffdShow to multiply of 16 (or 8, 32).
