Deoldify Vapoursynth filter

using:

clip = HAVC_main(clip=clip, EnableDeepEx=True, DeepExRefMerge=0, ScFrameDir="J:/tmp", DeepExModel=0, DeepExEncMode=0, DeepExMaxMemFrames=0)

coloring isn't good, but the chroma lag seems to be fixed.
You can get the file here.

using:

clip = HAVC_main(clip=clip, EnableDeepEx=True, DeepExMethod=1, DeepExRefMerge=0, ScFrameDir="J:/tmp", DeepExModel=0, DeepExEncMode=0, DeepExMaxMemFrames=0)

I get:

Failed to evaluate the script:
Python exception: HAVC_deepex: no reference frames found in 'J:/tmp', allowed format is: ref_nnnnnn.[png|jpg]

not setting 'ScFrameDir' I get:

2024-09-22 09:46:45.803
Failed to evaluate the script:
Python exception: HAVC_deepex: method != 0 but sc_framedir is unset

The error messages should be clear. 

In the first case has been provided  sc_framedir but in this folder are not available reference images in the format:  ref_nnnnnn.[png|jpg].
For example valid ref frames are ref_000000.png or ref_000310.jpg. It is mandatory to prefix all the reference images by the text "ref_", the frame number must be 6 digit long padded on the left with zeros, and the extension can be ".png" or ".jpg".

In the second case, has been specified DeepExMethod=1, which implies "HAVC + RF same as video", but not reference frame directory has been provided.
