Topic: "fake" 50fps videos and SVP on 60Hz Screen

I have a lot of film recordings from TV.  Here some channels use always 50fps Pal standard.
Recorded films show every frame two times. On a 60 Hz monitor svp can't interpolate this 50fps to 60fps and no smooth playback is possible. 

Is there any solution to use svp with such files on 60Hz screens? E.g. playing only every second frame and interpolating then to 60Hz or just inserting ten frames at random positions?

Re: "fake" 50fps videos and SVP on 60Hz Screen

If it's from a tv source I don't think it shows every frame two times, unless u're talking about a video that has been reencoded. If it's 50fps it's highly probable that it's interlaced so in that case u won't gain much from going from 50 to 60.

But if u really want to use SVP and it's interlaced u can choose a deinterlacing method that creates only 1 image for 2 frames so u get 25fps and then u interpolate with SVP. From experience I can tell that for movies and such it can improve smoothness sensation over a double yadif or bob deinterlacing method. For ball sports which I was more interested it did not fit since it creates too much artifacts around the ball.

I have looked at the frames and there is really no visible difference bewteen  two frames.   

This is what MediaInfo tells about the video.

Re: "fake" 50fps videos and SVP on 60Hz Screen

That is very good.
I have copied both files into the SVP-Folder.

But how do enable it? I see no new option in the svp programm?

Re: "fake" 50fps videos and SVP on 60Hz Screen

Look 'Drop every other frame' option in SVP Profile Settings window.

Re: "fake" 50fps videos and SVP on 60Hz Screen

In the video profil setting  I don't see a option 'Drop every other frame'.

I have made a screen shot of svp menu.
  I really don't knwo where to find 'Drop every other frame'.

restart the Manager?  big_smile

Re: "fake" 50fps videos and SVP on 60Hz Screen

Ok thanks. Now it works.

I had copied the old MSmoothFps instead of the new one.

Stupid mistake by my side.

Will this feature be in the new version which comes out soon?

Re: "fake" 50fps videos and SVP on 60Hz Screen

We can add it, and remove it in next version if nobody will use it smile
Lets try

Re: "fake" 50fps videos and SVP on 60Hz Screen

I tried this myself and a lot of videos i have seem to play smooth now, not like before. However I have blurry or ghost-like problems. Anyway to adjust for that?

Re: "fake" 50fps videos and SVP on 60Hz Screen

The "fake" 50fps videos play smooth now but the on screen message still shows  50 1:1  and not that the video is interpolated to the screen refreshrate.

Is this normal?

Re: "fake" 50fps videos and SVP on 60Hz Screen

SVPuser
No. Normal is to use smooth to screen refresh rate value from profiles window.

Re: "fake" 50fps videos and SVP on 60Hz Screen

That is what I did and SVP seem to work but still I have this osd message that tells no interpolation is done.

Re: "fake" 50fps videos and SVP on 60Hz Screen

Show your additional information from SVP tray menu - information. Please.

Re: "fake" 50fps videos and SVP on 60Hz Screen

The  variable framerate repair was checked  and therefore SVP didn't interpolate to the screen refershrate . Now SVP interpolates to the screerefreshrate (50fps  5:4).  But when I use drop every other frame the playback is very jerky.
