Here's the problem.

If we do the SVP settings now, we would be optimizing the settings for 60Hz.  For 24fps content, this means doing 2.5x interpolation.

However, by the time we're done, your display should run at 48Hz for 24fps video, 50Hz for 25fps video, and 60Hz for 30fps videos.

In other words, the refresh rate and the interpolated frame rate will always end up being 2x of the source content.

This is a problem because interpolating 24fps videos to 60Hz is worse for smoothness, worse for artifacts, and worse for CPU utilization.

If we figure out the best settings right now, then once we're done they will no longer be the best settings and we would have to do the process again to determine the best optimal settings.

I tried to tell you this with regards to your anime settings, but you insisted on optimizing for "To screen refresh" (which currently is only ever 60Hz and therefore 2.5x interpolation) instead of for 2x interpolation - 2x would have automatically given you optimal settings for 24fps @ 48Hz.

So I'll ask you a very simple question.  Which of the following 4 choices would you rather do?

• 1. Optimize your SVP settings for 2.5x (24fps -> 60Hz) interpolation now and forget about ever running your display at 48Hz for 24fps, 50Hz for 25fps videos, and just use 60Hz for everything

• 2. Optimize your SVP settings for 2.5x (24fps -> 60Hz) interpolation now and live with re-optimizing your settings for 2x (24fps -> 48Hz) interpolation later

• 3. Optimize your SVP settings for 2.5x (24fps -> 60Hz) interpolation now and not even worry about having sub-optimal settings for 2x (24fps -> 48Hz) interpolation later

• 4. Set up MPC-HC to run at 48Hz for 24fps now and then optimize your SVP settings a single that for that configuration

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.

*sigh*...

The problem with doing things that way is that, if we did the refresh rate stuff now, you will have both extra CPU headroom and reduced artifacts which will allow you to increase SVP's settings.  If you used 2x like I kept asking you to do and configured SVP around that, then your SVP settings would already be optimal and the refresh rate stuff would merely give you that smoother result without any increase in artifacting nor CPU utilization.

I really need to get to sleep, so in the mean time could you please please please figure out your optimal SVP settings when using 2x?  That will definitely save us some time, and it may free up enough CPU to increase the artifact masking and/or the "decrease grid step" option which can help reduce artifacting as well (fyi, don't use "to smallest step" on HD videos).

EDIT: Last thing, it may be wise to take a screen shot of both your current SVP settings and whatever settings you find to be optimal when using 2x - that way you can easily revert to one set of settings or the other until we get the refresh rate stuff out of the way.

Do you remember in SVP 4 there was an "Optimized for" with two options, one being "Film" and the other "Animation"?  This is due to the fact that the optimal settings for 2D animation will be different compared to film-like content.

SVP 3 obviously lacks such an automatic setting, so the user must manually change the settings accordingly.

BTW, while I've got you here, did you or did you not decide to get a "head start" and set up MPC-HC to automatically change the refresh rate?  You've been kind of missing in action, but I didn't want to guide you through the process until you were happy with regards to interpolation artifacts.

What if you close SVP? (right-click SVP's tray icon)

If your issue still occurs, then we can definitely rule out SVP.

Wait, I remember the last time I had 2.6 MT crash on me - it was when I switched from MPC-HC 1.7.9 to 1.7.10!

Needless to say, I reverted to 1.7.9 and instead just manually updated the integrated LAVfilters.  Since then I've been rock-solid stable.

Heck I've been so stable that I've decided to try out SVP 64bit since I feel that all the low-hanging fruit have been tended to with 32bit SVP.

I can't even remember the last time I've had 2.6 MT crash/freeze, and I use SVP for darned near everything.

That hardware is arguably overkill already for SVP.

Regardless, we should first ask whether these artifacts only occur on your projector or on other non-projector displays as well.

Unless you actively use MPC-HC's automatic resolution/refresh rate changer and, like me, don't really have any coding or command line ability...then it's a downgrade.

My main issue is that I use MPC-HC's automatic resolution/refresh rate changer to give a smoother result with fewer artifacts and lower CPU utilization, but setting up mpv to do the same thing requires at least a bit of coding-like or command-line ability which is a major weak point of mine due to it being much more abstract than dealing with hardware and/or GUIs.
