Trying out rife, it is heavy but also looks pretty good. One thing I have noticed, with RIFE SVP wants to use mediainfo. And on some mkv files this is really slow. Like over 20 seconds before rife kicks in. Files are on SMB share, Does not seem to hapen locally. Fixed by renaming mediainfo.dll in SVP folder. Is there a downside? Any cleaner way to disable mediainfo scanning?

Hi,

Looks good to me so far! CPU usage is pretty low on my I5 12600K even with 4K videos.

Since I'm passing the HDR data to  Madvr for tone mapping, am I right to disable all hdr options in SVP? Like So:

Since I didn't see any other threads on this, I'll leave this here.

This is a really nice feature, thanks for implementing the support for it.

Since I could finally get the HDR info to Madvr I decided to play around with 4K files (Even though my PJ is just 1080p). Using regular SVP, 4k seems to be really hard for the cpu, my 6700k was choking regularly doing 23,976 ->  59,94. Can't really use 48hz or 72hz ,for some reason my projector microstutters with those custom resolutions.

But using Nvidia Optical Flow it works fine. And the quality seems to be really good right  now with the auto settings.

All in all, it's nice to see that this project is still alive and improving.

I'm planning a similar setup for a secondary cheap SVP/Madvr machine and I wonder if a Celeron 3930 + GTX 1050 or GT1030 would be enough for decent results. That CPU is readily available, where as Pentium G4560 seems to be out of stock quite often and the price has gone up.

After some testing, I guess there is a smallish benefit. On the other hand, 4K videos seem to be crashing Kodi Dsplayer for me, so not really worth it.

Yeah, I have to do some tesing with the same source, both 1080p and 4K. I use projector and 106' screen, so chances are there is some benefit.

With 6700k and 1070 and test videos, performance seems to be enough. But you are right, I guess I need to test if I see any meaningfull difference.

I guess that's true, but I wonder if there is generally more "bitrate per pixel" if you know what I mean.

So, I have a theoretical question. In theory at least, 4K video on a 1080p screen should be better than 1080p video, because of double chroma resolution etc. Now, since I use Kodi Dsplayer, Madvr and ffdshow with 8 bit 4:2:0 conversion would I gain any benefit?

For example Netflix shows have both 1080p and 4K versions, would any of the benefit carry through the down conversion?

I have the same settings as Chainik's post, and edit SVP 4/script/overrride.js

levels.full                = true;

analyse.main.levels            = 3;
analyse.main.search.distance        = -8;
analyse.main.search.coarse.distance    = -12;

analyse.refine[0]            = {search:{distance:-6}};
analyse.refine[1]            = {search:{distance:-4}};

Thanks, I'll have to give this a try.

I ran in to the 10-bit issues with FFdshow as well. Will there be a good alternative in the future since the development of FFdshow has been stopped for years?

Thanks, that did solve the 50->60 issue and the CG scenes look nice like that. Of course the film parts look less smooth than 25->50 but I guess this is an ok compromise for now without easy decimation solution.

Ok, So I have the Discs, and copied everything to MKV containers.

The video is 25i, and after deinterlacing naturally 50 fps, which does not work well with SVP and 60hz.(On top of that I'm using PAL speed down). I can force the video to 25 fps, and then SVP works fine for the film parts, but some CGI parts appear to stutter.

I'm guessing decimation of the film parts would work, but I have no experience on the subject. Is it possible on the fly, with SVP (or ffdshow)?

I'll rephrase the question. Is it possible to get the right framerate multiplier with SVP 4 via profile/config file or something?

Except none of the multipliers in SVP 4 produce 62.5 fps with 25 fps content (Or I'm missing something)

I meant that different region DVDs handle this differently. Region 1 NTSC is 24/30 and Region 2 PAL, which I will have, is 25/50i (From what I can gather)

So, how would SVP handle the 25/50i switch?

I just ordered the complete DVD collection of Babylon 5 (PAL, Region 2) and did some research. Apparently it's in "hybrid" video format. For original NTSC, it's 24 fps for live action scenes and 30 fps for CGI scenes, and I guess the PAL version is 25 and 50i.

So I was wondering, how does SVP handle videos like these? Are there there any settings that would produce the best result?

Setup:

LAV filters
FFdshow
Madvr
Reclock
SVP

since 29,97 is half of resulting svp frame rate of 59,94 reclock should work ok?
Yes. In general case. In case if video framerate are standard 23.976 or 29.97 fps.
But if you have non standard video (for example 23.98) then ReClock will work incorrectly. See dropped frames in madVR statistics (by Ctrl-J).

Yeah that is true. But since most of my videos are 23.976 this is the best solution for now. Thanks for the information.
