The current packager no longer has a windows computer and effectively quit.

Write your application for the position below the line.

Does VapourSynth depend on memory (RAM) speed? I'm having issues with extremely large videos (6K-8K). They are choppy when playback is started but then it smooths out.

However, it also heavily stutters using interpolation (SVP/RIFE) but I'm seeing low CPU/GPU usage so I'm thinking it might be RAM related?

Yes, it's extremely dependent on ram bandwidth for 4k+ resolutions.

Is there a benchmark that I can run or how can I determine what speed is required?

For example, I'm on an i7-8700k (5.0 GHz) and the RAM is 32GB (8GBx4) but it's DDR4 at 3200 MHz. I can upgrade to DDR4 4133 MHz but I'm not sure if that is enough or if I need DDR5 (and a new motherboard/cpu, etc).

(Also, I think my issue might not be related to RAM [I've posted an issue on the VapourSynth GitHub] but I'm still interested in RAM requirements, etc)

You could also try to set a high max_cache_size and see if it helps http://www.vapoursynth.com/doc/pytho...max_cache_size

Can someone compile https://github.com/Setsugennoao/VapourSynth-removedirt for Win 64bit?
I'd like to know whether the fixes and changes Setsugennoa made to the source fix the crashes I encountered.

Got in touch with Setsugennoao, sadly his build also crashed the same way as https://github.com/handaimaoh/removedirtvs and https://github.com/pinterf/removedirtvs do.

Thanks. (still hoping an option to disable 'auto loading' will come some time)

The link “Plugins and Scripts“ is still linked to the old page (which does not exist anymore) on vapoursynth.com

Any chance for an official audio visualization plugin?

How would one port Avisynth: "mt_expand(y=3,u=-128,v=-128)" to Vapoursynth using core.std.Maximum ?

If I read that correctly, that call just processes the y plane normally and sets u and v to 128. (According to http://avisynth.nl/index.php/MaskTools2/mt_expand)

So I think you could do:

y, u, v = your_clip.std.SplitPlanes()
y = y.std.Maximum()
u = core.std.BlankClip(u, color=128)
v = core.std.BlankClip(v, color=128)
your_choice_of_name = core.std.ShufflePlanes([y,u,v], [0,0,0], vs.YUV)

Does that work? (If your clip isn't actually 8bpc, I suppose you'll need to scale 128 to an appropriate value with either simple algebra or one of the various helper functions out there.)
