I have several old 8mm home movie films that I had someone else convert to digital several years ago. I am now editing the digital files to clean them up and add effects. I have Nero 11, and am comfortable with that, but it doesn't appear to have anything to remove grain. The little bit posted on this forum about Nero isn't generally positive towards it.
I am debating purchasing an upgrade to Nero Platinum 2021 (about $138), but I don't think this latest version has anything to clean up noise, either. Is there another product which may be better for a casual user like myself where I can better spend my money?
Thanks for any advice.

Save your money.
Most on here will suggest you use avisynth and bespoke filters. However this comes with a steep learning curve - a road you may not wish to go down.
A free option is avidemux (do not worry about the avi bit) you load your video, select an output method other than copy, enter the video >> filters >> noise menu and select an option. Preview your video before saving it.
Be advised that ANY noise/grain removal comes at a cost of softening your video. Grain is intrinsic in film and often people leave it alone.
Beware, with most apps small details will disappear along with the grain/noise. And smeary artifacts will be created when there is motion.
Upload a sample if you want some seasoned users to give examples of what can be done.
Oh, that would be great! I'll try to upload a short video today.
Here is a short (under 30 second) video that has several problems.
First, there are spots with double images. I doubt if there is much I can do about that.
Second, there are frames that appear to jump up. That is, it is the same picture as the frame before, but higher. The next frame goes back down to normal. Again, I suspect there is nothing to do about this.
Third, the graininess. It would be great to clean this up.
I downloaded Film9, and watched the tutorial link provided above, and think this may work for me. An initial comparison of a short clip showed a lot of dirt removed.

The burned film is a loving testament to how many times the film was watched on a projector over the years, unfortunately.
This is actually a digital copy of a film I paid to have digitized a few years back. So I realize I am at the mercy of the quality of that conversion. I did have one of the films converted over 10 years ago, and again with the whole batch of them with a different company a few years back, and noticed a considerable improvement on the newer ones, so there's that, at least!
Here's a short segment with mild stabilization, color balance, levels, adjustments, motion compensated noise reduction. A little too dark?
That looks pretty good, considering the source, huh? Did you use Film9? and what do you mean be motion compensated noise reduction?
I am still learning Film9. For some reason, if I select 'Keep the dimensions for the Source Clip', it doesn't. It makes it more square. so I set it to 1920/1080, and that appears right. I also changed the capture type to WITH SYNCHRO and a speed of 17.6. without synchro and 18 was way too fast. I may adjust it further as I test longer clips.
I used a short AviSynth script. With a little annotation:
LWLibavVideoSource("Ramona 8MM tapes HM 16 Short clip.mp4", cache=false, prefer_hw=2) Trim(49,428) # just a short section that's easier to deal with Crop(60,0,-60,-0) # remove black borders TDecimate(mode=2, rate=17.0) # discard extra frames, 17 fps looks about right deblock_qed(quant1=35, quant2=40) # reduce blocking artifacts Stab(range=3, dxmax=4, dymax=30, mirror=15) # mostly vertical stabilization TemporalDegrain(sigma=8) # moderate noise reduction MergeChroma(aWarpSharp2(depth=5), aWarpSharp2(depth=25)) # sharpen luma a bit chroma more Spline36Resize(768, 576) # fix 4:3 aspect ratio ConvertToRGB() # color and levels RGBAdjust(rb=-20, gb=-23, bb=-43) # fix black level and balance RGBAdjust(r=245.0/228.0, g=245.0/198.0, b=245.0/160.0) # fix white level and balance ConvertToYV12() ColorYUV(gamma_y=50) # bring out a little shadow detail Tweak(sat=1.5) # intensify colors
Thanks for the script with the comments. I will play around with the video more and see what I can do.
