vapoursynth.Error: CMNET2: number of reference frames must be at least 2, found 2Cu Selur
Ps.: also uploaded a new Hybrid_havc_test
RE: Deoldify Vapoursynth filter - Dan64 - 25.04.2026
Please set ScMinFreq=15, I left some of defaults value of the previous release, CMNET2 need a stable source of reference frames and with the default value of threshold=0.10, it seems that was able to find only 2 reference frames.
I will update the RC.
Dan
RE: Deoldify Vapoursynth filter - Selur - 25.04.2026
But "number of reference frames must be at least 2, found 2" => shouldn't two be enough? Or did you mean that it need '3 or more' `?
Quote:Please set ScMinFreq=15, I left some of defaults value of the previous release,Don't really get that sentence, but using 'ScMinFreq=15':
clip = havc.HAVC_main(clip, ColorFix="none", BlackWhiteTune="none", EnableDeepEx=True, DeepExMethod=0, DeepExPreset="medium", DeepExRefMerge=0, ScFrameDir=None, ScMinFreq=15, ScNormalize=True, DeepExModel=3, DeepExEncMode=0)Let me know when defaults change, so that I can adjust the gui accordingly.
Cu Selur
RE: Deoldify Vapoursynth filter - Dan64 - 25.04.2026
Tomorrow I will release a new RC with the updated defaults.
Dan
RE: Deoldify Vapoursynth filter - Selur - 25.04.2026
Okay.
RE: Deoldify Vapoursynth filter - Dan64 - 25.04.2026
When is selected the model CMNET2, must be available the same options available for ColorMNet: Mode (remote/local), Frames (number of memory frames).
The Mode="remote all-ref" has been removed in 5.8.0. It was my unsuccessful attempt to implement a sliding memory window.
This approach has been implemented in CMNET2 and thanks to the permanent memory of Xmem++, now is working very well.
Dan
RE: Deoldify Vapoursynth filter - Selur - 26.04.2026
Uploaded an updated Hybrid_havc_test, let me know how that works.
Cu Selur
RE: Deoldify Vapoursynth filter - Dan64 - 26.04.2026
When I select CMNET2 is displayed this panel
The option Mode and Frames are missing, in this case should be displayed the same options of ColorMNet as shown below
Dan
RE: Deoldify Vapoursynth filter - Selur - 26.04.2026
Did you use the today updated Hybrid_havc_test?
Because for me it shows:

RE: Deoldify Vapoursynth filter - Dan64 - 26.04.2026
Now it works (probably I unzipped the old version)
I attached the new RC5.
Please check your defaults, the current ones are:
HAVC_main(clip: vs.VideoNode,
Preset: str = 'Medium',
FrameInterp: int = 0,
ColorModel: str = 'Video+ModelScope',
CombMethod: str = 'Simple',
VideoTune: str = 'VeryVivid',
ColorFix: str = 'Retinex/Red',
ColorTune: str = 'Light',
ColorMap: str = 'Red->Brown',
ColorTemp: str = "None",
BlackWhiteTune: str = 'Light',
BlackWhiteMode: int = 0,
BlackWhiteBlend: bool = True,
EnableDeepEx: bool = True,
DeepExMethod: int = 0,
DeepExPreset: str = 'Auto',
DeepExRefMerge: int = 0,
DeepExOnlyRefFrames: bool = False,
ScFrameDir: str = None,
ScThreshold: float = 0.10,
ScThtOffset: int = 1,
ScMinFreq: int = 15,
ScMinInt: int = 1,
ScThtSSIM: float = 0.0,
ScNormalize: bool = False,
DeepExModel: int = 0,
DeepExVivid: bool = False,
DeepExEncMode: int = 0,
DeepExMaxMemFrames=20,
RefRange: tuple[int, int] = (0, 0),
enable_fp16: bool = True, debug_level: int = 0)The main change is that now the section "Exemplar Models" is enabled by default and configured to use CMNET2.
