RestoreFPS, anyone?

[helge79]

Hi,

I have a terrible PAL-to-NTSC fieldblended DVD (so that almost every field is a blend). However, the pattern is quite regular and it looks like RestoreFPS should be able to handle it.

The problem is that I cannot find RestoreFPS.dll anywhere (I need one of the later versions which can reduce the framerate by more than a factor of 2, from 59.94fps to 25fps). All the download links in the original thread (http://forum.doom9.org/showthread.php?t=94091) are dead, and the version available in this library (http://avisynth.org/warpenterprises/) cannot handle conversions with a framerate difference of more than 2.

Thanks for your help!

Test this one, I think it's the latest: http://foxyshadis.slightlydark.com/random/RestoreFPS.zip

Thank you, foxyshadis, but this one also seems to be saying "Framerate conversion factor must be less than 2." The original discussion thread mentions that this limitation was removed at some point (and that it wasn't essential)... Still hoping to get a working version... If I downconvert to 49.95 rather than 24.975 (which is possible with the version I have), I see a nice pattern clean-blended-clean-blended-clean-etc... So, I am hoping that, if I get a working version of RestoreFPS and downconvert to 24.975, the video will come out clean...

I see a nice pattern clean-blended-clean-blended-clean-etc...
Shouldn't a "SelectEven()" after RestoreFPS be enough then? Or is the pattern not quite static?

The pattern is pretty good, but it is not stable at the scale of the entire movie, so SelectEven wouldn't work.

If there is a nice function that can decimate blends at the rate 2:1, I guess I could use it... :rolleyes: But it would probably be best just to get a working version of RestoreFPS...

It was never posted then; my version is from 20051023, the last day he posted anything. =\ I do have all of his other plugins though. You can try the sources in this thread (http://forum.doom9.org/showthread.php?t=118430) in case they're more up to date.

Too bad his R2 GitS pics are all gone, they were pretty cool.

I found one that's supposed to be from 05-18-05

Thank you very much! The version you have can actually change the framerate by more than a factor of two.

However, what I ended up doing with the movie (using the version of RestoreFPS I had) was downconverting the framerate from 59.94 to 50 and then decimating the blended frames with Cdeblend().Decimate(2). The output is not perfect, but pretty decent, I would say. In fact, I suspect that this two-step method may be more stable with respect to the phase uncertainty inherent to RestoreFPS than what one would get bluntly using Restore FPS to recover the original framerate (59.94 to 25).

PS: Quite frankly, this was probably the most f**ked-up DVD I've ever come across...

BTW, that version is SSE2 only (reading through some old posts).

I miss Mg262/Clouded. Nice guy, and smart as a whip.
