Loading and applying 3D LUTs

Reel.Deel · 2nd April 2016, 19:43

Just wondering how to go about loading and using .cube 3D LUTs in VapourSynth. I would like to use these LUTs here (1 / 2), but I'm not sure if this can this be done with std.Lut or is it one-of-those-things that will require a plugin?

Edit - I'm not the author, just posting link here for convenience.
------------------
Timecube, a plugin to load and apply 3D luts to a video:

Sources: https://github.com/sekrit-twc/timecube
Binary: https://github.com/sekrit-twc/timecube/releases

Usage:
timecube.Cube(clip clip, string cube="")

Parameters:
clip = Input clip, colorspace must be RGBS.
cube = Path to 3D lut file, only .cube files are supported.

No idea about vs, but you cal always use free Resolve.

I have Resolve but I would like to do be able to do it in VapourSynth. For me VS would be a bit more straight forward and would not require any intermediate files since I can easily pipe to x264/x265.

You'll need a new plugin for that. Is there format actually documented somewhere?

Looks surprisingly simple, especially since there's sample code for reading the files is in there too. Maybe I'll have a go at it some day but probably not soon.

Good to hear that it looks simple. Hopefully we'll see this integrated into VS sometime. Thanks for the feedback.

Have there been any news on this? Having 3Dluts would be great for professional workflows where you want to apply certain looks to your ungraded footage.

TIA!

I currently use FFMPEG's 3DLut filter for .cube files. It's not as convenient as having a Vapoursynth/Avisynth plugin, but it's more flexible than Davinci Resolve. Resolve doesn't support efficient lossless codecs (FFV1, X264 lossless, UTVideo, etc), avisynth input, or piping VapourSynth scripts.

Why didn't anyone tell me there's code I can borrow? Maybe I'll actually do something about this after I release R38

If you can provide some before/after clips with a lut applied (and the lut file) so we can easily test a plugin that'd be great. Or this is not going to happen...

Here's my image before/after of a lut, lut file included

I don't know how to use the vscube plugin. Any pointers would be appreciated.

Revgen · 9th June 2017, 09:07

I'm also receiving the "Cube: must be RGBS" error. The .cube file works fine with FFMPEG.

UPDATE:

Okay. It works now. Thank you.

I got an error "Resize error 3074: no path between colorspaces", what does it means?
