Topic: Video wavy and Scene Transition Stutter

I've actually put this off longer than I should have, but it's annoying me.

As you can see, the character outlines get really wavy or distorted I should say when too much movement in the video take place. I tested the orange line test and nothing seemed out of the ordinary except the usual scene stutter along with the orange line.

http://www.svp-team.com/files/demo/space_60.mkv I tested the video and I actually got quite a few stuttering here and there and the video stops at around 0:29 for some reason and never finishes (unless that is where it ends).

I have a NVIDIA GTX 560M with/2GB GDDR5 VRAM, i7, Windows 7. Using LCD 1600x900.
Here is my SVP profile:http://i.imgur.com/cCVELFS.png

Also edited my override.js
smooth.scene.limits.scene    = 2000;
smooth.scene.limits.zero        = 100;
smooth.scene.limits.blocks    = 51;

analyse.main.penalty.lambda        = 0.6;
analyse.main.penalty.plevel        = 1.7;
analyse.main.penalty.lsad        = 4000;


Also sometimes using "frame crop: by 4 pixels on each side", but not really sure what it does.

Conclusion of my problems:
1. Scene Transition Stutter [usually with Fullscreen]
2. Wavy Character Outlines



Someone please help me! I would really appreciate it!

Re: Video wavy and Scene Transition Stutter

Increase "motion vectors grid" value

Re: Video wavy and Scene Transition Stutter

I put it at 32px Large 0.

It seemed to help a bit with the stuttering...But the video still stutters pretty often While it feels a lot smoother and basically not too much stutter every 3 seconds like before, windowed mode always seems so fluid compared to fullscreen (where it is more choppy).

Apparently, higher motion vector means less artifacts, but less fluidity. I fixed the artifacts portion of the videos without the higher motion vectors grid value.

Re: Video wavy and Scene Transition Stutter

Okay, I also realized when I used ctrl+j, I realized it would be like this:

Windowed mode:

Average stats
  rendering 5.90ms
  present 0.13ms
Max stats (5s)
  rendering 8.30ms
  present 0.13ms

Fullscreen mode:

Average stats
  rendering 31.30ms
  present 0.13ms
Max stats (5s)
  rendering 24.60ms
  present 2.48ms

Idk how these values really work but all I know is that whenever I watch in windowed mode, it actually feels like SVP is on and it's 60fps super smooth.

If I watch in fullscreen, it feels like it's a very sloppy 60fps.


Edit: Turns out I'm stupid and didn't activate madvr Exclusive mode. This fixed the non 60fps feel for the most part...

Now I just have a problem with that messy wavy character outlines whenever a big scene transition occurs.
