Regarding Neat Video: I've tested a lot of other softwares and plugins and conclueded this was the best (of the worst) way of filtering without loosing details (since you manage how to set it's parameters appropriately). What I noticed is that all filtering aways kills the details. But I'm new to Avisynth, and I'm pretty sure that with more knowlege I'll find a better way of doing it. |

Take some random video. a) Downscale with bicubicresize(halfwidth,halfheight,0.5,0.25). Upscale with VideoEnhancer. It will achieve "almost nothing" compared to a simple re-scaling. b) Downscale with gaussresize(halfwidth,halfheight,p=100). Upscale with VideoEnhancer. It will achieve a good improvement over a simple re-scaling. TSR can work pretty good when the input is of the "decimated resolution" kind. The only pity is that the vast majority of all sources doesn't fall into this category. Quote:
Do a forum search on the term "super resolution" / "superresolution". The topic has been discussed a few times already. Usual partipiciants have been: the naive optimists stating "THIS IS IT!", and the pessimistic naysayers stating "Y've been rickrolled". Oh, and some others that were throwing whitepapers about different sensational breakthrough algorithms. The current status is: We have lots of paper, but no functioning general-purpose superresolution.

However, let me point out the term "general purpose".
It's a different story when talking about "specialised conditions". For example, the topic of this very thread is a script that truly performs temporal superresolution. It is just limited by two conditions: a) the input has to be interlaced. (Interlacing is a native form of "decimated resolution") b) the more lowpass filtering was used to create the original interlacing, the less effective the TSR part will be. (Lowpassing effectively changes "decimation" into "blurring")

is this supposed to be a 30fps-oriented deinterlacer? it seems to have half the framerate (or at least notable motion) that mcbob gives me... on even frames, the image seems to be just slightly changed from the odd ones...
love the speed, tho! |

How to use it for intermediate files with x264 encoding?
Well, this is my first experience with any lossless video codec. I want to use it for intermediate files that are the product of heavy processing in Avisynth. Later I plan to encode those lossless files with x264 2-pass method.
So far I was able to create AVI files Code:
Video ID : 0 Format : ULY0 Codec ID : ULY0 Duration : 1mn 0s Bit rate : 50.7 Mbps Width : 720 pixels Height : 576 pixels Display aspect ratio : 5:4 Frame rate : 25.000 fps Standard : PAL Bits/(Pixel*Frame) : 4.893 Stream size : 363 MiB (100%) Code:
avs2avi.exe myscript.avs -c ULY0 What is the recommended way to feed UtVideo file into x264 encoder then? |

And it's a nice place to find all the filters needed for SSU & QTGMC in the one place (thanks Robert!) Also for those with little Avisynth experience, the walk thru Robert has on his website (to get his filter & QTGMC) working is also pretty helpful !! Quote:
A simple command like MCTemporalDenoise(settings="low", gpu=true) will beat most things for denoising and speed !!! But of course it's probably far more customisable than NEATVideo !!! 7ek Last edited by 7ekno; 15th December 2010 at 05:22. Reason: added links |

I don't think MVTools2 supports RGB input and MVTools2 is at the core of the script. |

If it has to be by all means, you can do RGB, too. Take RGB in, clone it to YV12 to do the motion search. Then separate the three RGB channels to three greyscale YV12 clips, perform basically 3 times TGMC on that bunch, and join back to RGB.

"v.fast" is not recognised, so it reverts to the default of "Slower". |
