I've already used KillerSpots in Vapoursynth which removed a lot of the spots, but not all.
For a second pass, I have also tried switching over to Avisynth and using the additional settings in DeSpot, but I can't seem to get it to remove the remaining spots.
Any suggestions?
Sample clip
There is also some additional noise on the whole video frames which I am unable to remove - it looks like a strange moiré pattern?

Masked Spotless with high (i.e. 5 or 6) temporal radius?
For example:
## Starting applying 'EdgeMask (Prewitt)' masked filtering for vsSpotLess
clipMask = clip
clipMask = core.std.Prewitt(clip=clipMask)
clipMask = core.std.Maximum(clipMask)
clipMask = core.std.ShufflePlanes(clips=[clipMask], planes=[0], colorfamily=vs.GRAY)
clipFiltered = clip
# Spot removal using SpotLess
clipFiltered = SpotLess.SpotLess(clip=clipFiltered, radT=6, pel=1, smoother="zsmooth")
clipMask = core.resize.Bicubic(clip=clipMask, format=vs.YUV422P10, range_s="limited", dither_type="error_diffusion")
clip = core.std.MaskedMerge(clip, clipFiltered, clipMask) # PrewittEdgeMask
## Finished applying 'PrewittEdgeMask' masked filtering for vsSpotLess
Probably would be better to apply something like this on the source before applying Despot and you might have to try different masks and settings.

I just tried running the original ProRes 422HQ file through AVIsynth to re-try the DeSpot filter but now I get a preview error - ConvertToYV12 - only 8 bit sources allowed.
Do I need to convert to standard ProRes 422 for this to work?

Strange, according to the source code Hybrid should be aware that Avisynths DeSpot requires YV12@8bit.
Also tried it and it works fine here:
LWLibavVideoSource("G:\TestClips&Co\files\ProRes\Test Patterns Resolve 422 HQ 10-bit.mov",cache=false,dr=true,format="YUV422P10", prefer_hw=0,repeat=true)
# current resolution: 720x576
# despotting using DeSpot
# Converting from 10 to 8bit for DeSpot
ConvertBits(8)
ConvertToYV12(interlaced=false)
DeSpot(median=false,interlaced=false)
Hybrid automatically converted to 8bit and YV12.

Also, where do I find EdgeMask?

You enable the Masking controls (Filtering->Masking->Ui->Show 'Masked'-controls) and then the controls are next to Spotless.
