Deinterlacing with SVP

All types of software deinterlacers sucks 
MAG79 could tell how to use true hardware deinterlace on NV cards with SVP. The short answer is "LAV CUVID"

Thanks guys, yeah I use lav video / hardware deinterlacer usually but still of course it would be fantastic if it was all part of the same smooth video product. Itd be a monster of a task to implement in software though, ie to have it run in the same flow as normal interpolation. Back to gpu hardware deinterlacing it is. Should going from 50 -> 52.08 fps cause microjudder in the output video, as this is what svp seems to do at the moment, is there a way to improve the interpolation in this scenario doing such a small adjustment in fps.

I use 50hz on my Samsung HDTV, as other rates don't behave very well and don't display as accurate colors as 50hz. So my aim is to have all my content run at 50hz.

So for example, many of the Star Trek TNG Pal DVDs are

1) 25 Interlaced, so need to be deinterlaced (deinterlaced to 50p using LAV Video hardware deinterlacing)
2) Need to be slowed down by 4% by ReClock so they play at the correct rate (achieved with ffdshow), which would slow 50fps down to 48fps.

So to both deinterlace, and slowdown by 4%, aswell as achieve 50fps output I must add an intermediate step between deinterlacing, and reclock slowing the rate down, that is

1b) Use SVP to speed up the 50fps deinterlaced content, to 52.08fps, which when slowed down by reclock by 4% gives exactly 50.00000 fps.

So I don't see any frame drops at all, BUT the rate change from 50 to 52.08 seems to add a judder of some sort, I assume due to the fact that the two rates are so close together.

I have just gotten so used to playing 25fps material at 24 fps (increased then to 50 by svp) that it's very noticeable to me when not doing the pal speed down ie the voices are noticibly too high pitched and movement is too fast.

Svp output after changing from 24 to 50 is so good that I think this process gives me a better playback experience as at least it sounds correct and is playing back at the correct rate.

Hi Mag, thanks for you're post. Perhaps I am mixed up I have made a 1 minute sample of one of these files for you to see.

When using LAV Video adaptive deinterlacing setting, it comes out at 50fps progressive and looks great BUT compared to the NTSC version of the same DVD for example, it does play faster, and is higher pitched.

Are you saying pal speed down shouldn't be needed here? I think it is still needed and therefore still think I need to use svp to change the rate to 52.08~fps before reclock slows it down.

How do you suggest I play back this file and achieve my goal of playing at 50hz and slowed down or would you play differently?

Wow thanks very much Mag!!! Out of interest how did you check that content of the sample. I might try to fix these sources so that I dont need specific settings for them.

Thanks!

EDIT: What would you suggest I could use to fix this material? I assume its some telicine flag thats not set correctly? Should the LAV decoder do the IVTC based on this flag, even if deinterlacing is set to off?

Of course I'd love to fix the material so that I don't need any manual settings changes per content, ie switching from 50p to 25p in LAVs settings etc.

Thats great, thanks Mag. They were ripped from the original dvds. I might have to invest in the blu-ray versions of these DVDs Thanks again.

I own these PAL DVDs myself. I ripped using makemkv keeping original mpeg2 stream so the mpeg2 must have been encoded wrong on the source DVDs I guess, as I don't think makemkv does anything to the original stream. Each episode comes to about 1.5gb mkv.
