Re: DGDecodeNV(deinterlace=1) vs. KernelDeint

<Here> is a page with some "objective numbers" about various (bob-) deinterlacers. But there is bad news: For you , QTGMC probably is out of reach, anyway. Reason: the package-of-plugins for QTGMC is approx. 18.5 MB in size. And as we have learned, you obviously cannot download such a gigantic file...

Re: need some help w/ decomb for a bizzarre clip

It's 99.99% sure that the source was not shot in "720i". Simple reason, this format does not exist. Probably a 1080i sequence was directly downsized to 720p, without respecting the interlacing. Since the fields have been blended together, there is no combing anymore, therfore there is nothing that c...

Re: i7 2600k

There are 64bit-builds of Avisynth out there, but none of them are "official". What they have in common is that they're not fully stable (though it's not quite sure if that's a problem of the Avisynth core, or of the same-unofficial x64-plugins, or both.) For most usual tasks, Avisynth x64 should be...

Re: Best way to decimate...

That was only theoretical. I've used Srestore with good success under both 2.5.8.5.MT and 2.6.MT. (Of course without actually using multithreading - that's technically impossible with Srestore.) Problems that I see here are: 1) it's the very beginning, which is always critical. The start is just bla...

Re: Best way to decimate...

You should use official Avisynth releases for troubleshooting, not experimental MT versions. If you're pedantic, not even the official 2.5.8 is safe for testing. IIRC, Srestore was developped in Avisynth 2.5. 6 . Given the tricky nature of the script (conditional environment / scriptclip), you can'...

Re: About frame decimation

It is impossible to do that. Broken down to the basics, Mpeg compression calculates the difference between currentFrame and previousFrame. This difference then is compressed. During playback, the current frame can only be decoded after the previous frame has been decoded, and so on. In other words, ...

Re: DGAvcDecDI crashes when playing mkv-file

The MT documentation warns that SetMTMode(5,0) is very slow. Here you can see it.. That's not what the documentation is talking about. Mode 5 is "slow" because it *effectively* uses only 1 Thread. The slowdown you're experiencing here has nothing to do with that. First off, I'm wondering what you'r...

Re: DGDecNV - CUDA + x264 HighLevel@4.1

Just in case your script is using multithreading via SetMTmode() - these days I had a case where such a script locked up right after loading. (Don't know the cause - generally DGDecNV now works flawlessly with SetMTmode. Just this one time, it didn't.) The following little fix did make the problem d...

Feel free to use --preset ultrafast for the 2nd pass, and see it fly along. However, be prepared for reduced quality. The point is that the 1st pass doesn't need to put much effort into motion search, RD stuff, and whatnotelse. Basically, it's only there to figure out where to put I-, P- and B-frame...

Perhaps it wasn't quite clear ... my comment wasn't targeting you, but only Nvidia. I perfectly understand them to allow only mod4, in order to avoid potential problems. And after all, this is an Avisynth filter. A script has to be made anyway, and writing a crop() command manually is not a big deal...

There is a good reason for this mod4 restriction - think about e.g. interlaced mpeg2 :evil: This restriction can be loosened in several cases (horizontal-only cropping, progressive content, ...), but not universally .

Re: Feature Requests

Still, shouldn't it be considered to add some sort of deblocking to DGDecodeNV ? In particular for Mpeg-2 sources. Fact is, the white bearded man DGDecode can do quantiser-adaptive deblocking on mpeg-1/2, but the young guy DGDecodeNV can do not. One could argue this is a regression. :)

Re: Feature Requests

The deblocking is performed. As you noted (with slight misspelling), H.264 is doing "in-loop deblocking". That means that deblocking is not done "after the fact" like you do when e.g. playing back Xvid videos. In H.264, the deblocking is an essential "inner" process of both encoding and decoding. If...

OH COOL!!! I hope your first one will be a denoiser. Avisynth script denoisers can be painfully slow (like mc_spuds, MCTemporalDenoise, etc...). Those are highly sophisticated denoising scripts, making very big effort to come to an optimal result. An important part of the big effort is active motio...
