HI Andrew,
Have enjoyed you AviSynth restoration videos and others (Lamy, NM), a fan and subscriber.
I have purchased and use Neat Video on older SD interlaced AVI files (BTW: great support). The company suggests it be used first, prior to any other filters, such as deinterlacing.
Have experimented, but have used it as prescribed, and the saved files as ProRes, followed by the deinterlacing process as you describe through AviSynth or within After Effects using Field Kits plug in demo. Unfortunately Fields Kits program can not create 60 frames per second within Premiere pro, but will do it within After Effects.
The order is important. In future video you might test this out.
Thanks for all your help. You are a A great teacher.

Hello good rundown of SMDegrain. For heavy grain sources I would first evaluate a good spatial (or soft temporal-spatial) denoiser that looks rather clean in as a still frame (prefilter=4 maybe), and then feed that as a prefilter to let SMDegrain bring coherence in the temporal domain. With low contrast sources like this I think lowering thSAD and tr a bit can be helpful.
Dogway: I messed with prefiltering a bit, and it's debatable whether it's better or not for the sample clip I used in this post. However, the "kitchen sink" method works great on other SD footage I've processed, and it uses extensive prefiltering, so I guess it's something to try on a case-by-case basis.
You were definitely right about changing thSAD, though. Bumping it up helped my sample clip a lot. I'll do some more testing, and update the post.
Hello Andrew I'm having a problem with missing Dither_lut8 called by SMDgrain. I have a dither.dll shown by AVIsynth tool. Where can I find it? Libfftw3f-3.dll seems to be having problem too. It's in both Sys32 and Wow64 but AVIsynth tool says it's needed by MVTools.dll and I should put it in. Can't figure out either one. Thank you for your time. Steep learning curve.
Got the problems fixed Thank you but when I ran the script it didn't do anything to the video. I adjusted the setting to max for a second try and still nothing. I took the same frame from each video and they were all exactly the same. Had some trouble getting the batch file to run but I finally got it right. When using AVSPMOD I can watch the video great until I add the QTGMC then it becomes basically unusable. Windows reports "not responding" but it is still working but extremely slowly. Do you have any insight into this problem? Could you possibly send a screen shot of your Avisynth tool for both the 32 and 64? I would like to see what I am probably missing or what I don't need. Thanks again.
Mary,
I have a bunch of filters installed, so I'm not sure how helpful my avstool dump would be.
You shouldn't try to *play back* video with QTGMC or other hefty filters applied inside AVSPMod - they're incredibly demanding, and not designed for real-time playback. It's better to just go to a frame and use the F5 key to update that frame when you change settings, then maybe move a couple of frames forward using the arrow keys.
Could you do me a favor and post your .avs script? It might help me narrow down the issues you're having.
Cool. Some other notes:
- If you aren't using f3kdb, then you can remove the SetFilterMTMode line with it at the the top and the commented-out line towards the bottom.
- If you plan on denoising before QTGMC, make sure to set the interlaced option to true.
- If you have a quad-core processor without hyperthreading (or dual-core with hyperthreading), then your PreFetch and EdiThreads look fine. If you have a quad-core with hyperthreading, you could double the numbers for each.
Your .bat script points to the original video file as the input rather than the .avs script. Try changing that, then see what you get.
Also, you can switch to "Slower" rather than "Very Slow" for the QTGMC preset. The quality difference isn't really noticeable.
I knew it was something dumb like that. I remember when I was first doing the .bat the CMD would just flash up and go off. I looked around on the web and got something to use the video file name. Must have been for some other process. so basically I was just encoding the file back to exactly what I started with.:( I was using .avsi when I changed it to .avs wonders of wonders it worked. :) Thank you so much. Now I can start to see what the different parameters do to make my video better. Thanks again.
What version of AVISynth are you running?
You *should* also be able to raise PreFetch to 8 without a problem, but if it still freezes then maybe compromise and do 6? It's usually EdiThreads that can jam up the encoding if it's set too high, and your setting of 2 should be fine.
Also, if you want to benchmark your script for resource usage using different settings, you can try downloading and running avsmeter (with something like "avsmeter youscript.avs") in the same directory as your script.
If you've disabled Hyperthreading, you won't get full performance out of the multithreaded filters.
Most modern multithreaded filters are detected automatically by AVISynth+, but if you want to enable it manually, you can do a SetFilterMTMode("f3kdb", 2) command.
As to EditThreads, set it to half your total number of logical cores (you can find that in task manager). there's no benefit to going above that.
Hello and thank you for your time to test all of theses variants. As I can see, you always use the denoiser before using QTGMC in the default-setting.
But does QTGMC in default not also remove some noise? And why do not use the denoise options that are included in QTGMC (or even QTGMC+ -Scripts/blob/master/MIX%20mods/QTGMC%2B.avsi)?
Denoiser II: Powerful Features for Professional Results
Denoiser II combines data over several frames to separate the noise from the image, giving users a professionally smoothed result that preserves fine details. Options like Frame Sample, Motion Estimation, Noise Hint and Shadow Offset create new sample frames, preserve fast-moving action, reduce chroma blotches, or clean up shadow areas, and are ideal for a number of workflow issues, such as:
Motion estimation for high and low motion: High-speed camera movements are different than slow pans, but Denoiser II can preserve detail even in fast-moving action sequences. Its Motion Estimation technology/feature compares successive frames to learn what is natural motion vs noise in the scene.
Chromakeying and other fine tuning: Denosier II offers a number of fine tuning features that allow users to minimize over-smoothing, correct green chroma tinge, focus on shadows or de-emphasize highlights, all without losing image detail.
Separate Video and Film modes: Two modes let users characterize the noise so Denoiser II can achieve the most accurate results. Video mode adjusts the Luma and Chroma channels for better smoothing in black-and-white or full color. Film mode has adjustments for Red, Green and Blue channels that are ideal for material shot on film.
