SVP 4 Stuttering problem while watching anime (Page 3 of 8)

You don't have to, it's just that the other settings really don't work that well for anime (you'll get weird artifacts).

Please don't change that.  You get less artifacts when using an exact multiple and using 2x also give lower CPU utilization.  Right now 2x will not be as smooth, but that's because we aren't quite done yet.

Basically, after we get SVP squared away, I was going to tell you how to set up MPC-HC so that automatically switches to the best refresh rate based on the frame rate of the video content (for example, 24fps is smoother at 48Hz than it is at 60Hz).  If you want to get a head-start, see this thread starting from this port.

First off, use "double rate (2x)".

If you have the CPU headroom try using "Complicated" with either 'Uniform' or '1.5m'.  Note that you may have to lower some other settings if the increase in CPU utilization is too much.

If that is still not good enough, try lowering the "Motion vectors grid" to something like '16px', '24px', etc.

You can also try switching the "Processing of scene changes" between 'Blend' and 'Repeat' and see which is preferable (assuming it makes a difference that is).

And there's always the option of increasing the "Artifact masking" which will sacrifice smoothness but will make artifacts less noticeable. This increases CPU utilization a bit.

Lastly, you could even increase the settings for "Decrease grid step", but the difference is arguably placebo-level (and for HD content, do not use the setting "to smallest step"); this can increase the CPU by quite a lot.

Good luck, I must go to bed for the night.

Hi and sorry aigan for my absance. So,yestrday i saw a strange thing: on the option of mpc hc (Hardware acceleration) i set DVXA(copy-back) but below this option i say to me Active decoder : <inactive>. Is it normal??

Hum....ok. I have another question: i can't set the option in svp (motion vectors precison "half pixel") because it makes uglys strange artifacts. Like.....like i don't know
like a motion is repeated several times. Why?

No when i set "one pixel" or "two pixels" is ok. But when i set "half pixel" (the best option i think) the ugly artifacts occur!

Erm....yes i remeber that....but really i don't undstand what i have to do now hahaha sorry. Maybe  Have i to set an option in mpc hc?

Well....yes i'm happy even i think there are too much artifacts in my opinion. No i keep svp set to "To screeen fresh rate" beacouse is so smoother than "to 2x".

OK but....with the option"to screen refresh rate" the cpu usage is under 45%......

With 2x there aren't optimal settings...beacause it isn't smooth it is like Svp Disabled!!!

Have you tried these?  They'll eat your CPU right up to the point that you might have to set 'Target frame rate' to "2x".

Shader = Complicated
Decrease grid step = By two with global refinement
Search Radius = Large
Artifacts masking = [user choice]
Processing of scene changes = Blend adjacent frames

Not true, 24fps with 2x @ 48Hz is smoother and has less artifacts than 24fps with 2.5x @ 60Hz, though the latter may "feel" faster.

That's why I was trying to get AndyDragneel to configure his/her settings around 2x, because the refresh rate stuff will be to have MPC-HC automatically switch to 48Hz for 24fps content.

You don't have to use all of those settings at the same time, and "Decrease grid step" can be set to one of the lower settings like "Local refinements" or, if you must, even "Small step" if your CPU can't handle "Global" (again, don't use "smallest" on HD content).

For film-like content, you basically would just use the highest settings possible in SVP.

Just remember that certain settings (like "Motion vectors precision") have much more CPU impact than other settings but arguably have less of a result on the final video.

Actually, you know what, since you're here and I'm not going to bed for 2-3 hours still, do you think we could set up the refresh rate stuff first?

First off, it would be a good idea if we added a custom refresh rate for 50Hz, so please go through the process I lined out previously for making custom resolutions; here it is again for your convenience:

Run CRU.exe

Under "detailed resolutions", click "Add..."

Set the "Timing" to "Automatic - LCD native"

Next to "Active", input "1366" under "Horizontal" and input "768" under "Vertical"

Next to "Refresh rate", input "50"

Click OK; this should close the smaller window

Click OK again; this should close the bigger window

In CRU, you should now have at least three listings for 1366x768 - one at 60Hz, one at 50Hz, and one at 48Hz (there might also be one for 40Hz, you can either ignore that or even remove it)

After this, restart your PC, and then test setting your refresh rate to 50Hz; signs of it not working correctly would be a flickery screen, weird colors, or a black screen.

Important!: If setting your screen refresh rate to 50Hz does in fact makes your computer unusable and you cannot change it back, restart your PC (you may have to "cut the power" by holding down the power button) then before it starts to load windows, press F8 over and over again.  On the menu that appears, you should be able to select something that says "low resolution mode" or 640x480.  Select that and you should be able to boot and see your desktop (though massively cramped). Then change your resolution back to 1366x768, but before clicking Apply or OK, go into Advanced and set the refresh rate to 60Hz, and click Apply/OK in that window - you should now have 1366x768 @ 60Hz.
