RE: Deoldify Vapoursynth filter - Selur - 28.03.2024
DDConrol, on my system with a 1000x542 source:
16bit (FP16 enabled) ~37.69fps
32bit (FP16 disabled) ~22.9fps
but speeds will differ depending on the used card and input.

I will add this option in the next release

Have to taken to handle scene changes properly?
Cu Selur
I added also a threshold to detect scene changes, if the average of pixels substituted is above this threshold (for example 80%) it will be considered a scene change and the restored -/+ frame will be replaced by the current frame (eventually de-saturated).

RE: Deoldify Vapoursynth filter - Dan64 - 29.03.2024
Hello Selur,
I completed the changes for the new version 3.0.0.
On filtering side I improved the "chroma stabilizer" to solve the problem related to gray areas in the past/future frames.
I also added the requested changes on ddcolor regrading the optional fp16 and delayed loading of the filter.
But the big changes are on the interface of the filter that has changed significantly.
As agreed I removed the post-process stabilization filters in another filter called: ddeoldify_stabilizer
The new header for ddeoldify is
def ddeoldify(
clip: vs.VideoNode, color_method: int = 2, merge_weight: float = 0.4, deoldify_params: list = [0, 24, 1.0, 0.0], ddcolor_params: list = [1, 24, 1.0, 0.0], ddcolor_tweaks: list = [False, 0.4, 0.4, 0.0, 1.0, 1.0, True, 1], combine_params: list = [False, 0.6, 2.0, 0.15, 0.2, 0.3, 0.6, 1.0], darkness: list = [False, 0.2, 0.8], chroma_resize: bool = True, device_index: int = 0, np_threads: int = 8, torch_hub_dir: str = model_dir) -> vs.VideoNode:

:param clip: clip to process, only RGB24 format is supported.
:param color_method: method used to combine deoldify() with ddcolor() (default = 2):
0 : deoldify only (no merge)
1 : ddcolor only (no merge)
2 : Simple Merge:
the images are combined using a weighted merge, where the parameter merge_weight
represent the weight assigned to the colors provided by ddcolor()
3 : Adaptive Luma Merge:
given that the ddcolor() perfomance is quite bad on dark scenes, the images are
combined by decreasing the weight assigned to ddcolor() when the luma is
below a given threshold given by: luma_threshold.
For example with: luma_threshold = 0.6 and alpha = 1, the weight assigned to
ddcolor() will start to decrease linearly when the luma < 60% till "min_weight".
For alpha=2, begins to decrease quadratically.
4 : Constrained Chroma Merge:
given that the colors provided by deoldify() are more conservative and stable
than the colors obtained with ddcolor() images are combined by assigning
a limit to the amount of difference in chroma values between deoldify() and
ddcolor() this limit is defined by the parameter threshold. The limit is applied
to the image converted to "YUV". For example when threshold=0.1, the chroma
values "U","V" of ddcolor() image will be constrained to have an absolute
percentage difference respect to "U","V" provided by deoldify() not higher than 10%
5 : Luma Masked Merge:
the clips are combined using a mask merge, the pixels of ddcolor() with luma < luma_mask_limit
will be filled with the pixels of deoldify(), if the parameter merge_weight > 0

"""As you can see the main changes applied are:
1) The main parameters of deoldify/ddcolor are now grouped in separated lists.
2) All the tweaks parameters of ddcolor (including the fp16 flag) has been included in a dedicated list.
3) All the parameters used by the combination methods are also grouped in a dedicated list
4) "dd_mthod" has been renamed in "color_method"
5) the filter "darkness" now has really the meaning to dark more the dark areas, while the "chroma smoothing" version has been moved in ddeoldify_stabilizer
The header for ddeoldify_stabilizer is

This filter is the only enabled by default, because is the more effective in stabilizing the colors
I hope that you will be able to apply the changes in Hybrid.
Thanks and Happy Easter,
Dan
I small update (no changes on filters headers)

RE: Deoldify Vapoursynth filter - Selur - 29.03.2024
Happy Eastern, to you too.
You manage to add more and more parameters.
ddeoldify has 33 parameters (not counting the 'clip' an 'torch_hub_dir' parameters)
ddeoldify_stabilizer has 16 parameters (not counting the 'clip' and 'colstab_algo' parameters)
Nearly 50 parameters, that is not usable or maintainable.
=> Sorry, but I'll have to think about whether:
a. I drop support for the filter altogether
or
b. how I can remove options from the UI and add a custom command line for the user.
Regarding a., Atm. I think I will adjust Hybrid to only, set:
- color_method
- merge_weight
- deoldify_params
- ddcolor_params
- device_index
- np_threads
Main downside to this, aside from that the user will have to read up on how to use this filter is that Hybrid can no longer call dd_video_stabilizer/ddeoldify_stabilizer.
The user would have to do that on their own in a custom section. (which probably nobody nearly would do)
=> not sure whether dropping support for the filter might be a better option.

RE: Deoldify Vapoursynth filter - Dan64 - 29.03.2024
I can understand.
It makes sense to add in the GUI only the most useful options (*).
I don't understand if you can add support to ddeoldify_stabilizer or I have to move at least the chroma_stabilizer in deoldify.
Could you clarify better ?
Thanks,
Dan
(*) It is possible reduce the number of options by just using their default values.
RE: Deoldify Vapoursynth filter - Selur - 29.03.2024
I got an idea how to design the UI to be still able to add chroma_stabilizer.
=> I'll test some stuff.

Cu Selur
Previously I added the fps16 flag in the ddcolor list, then I decided to move this parameter in ddcolor_tweak and I forget to remove it from the description of ddcolor list.
If you prefer I can add in the ddcolor list.
In the ddcolor_tweak list the most useful params are: bright, gamma, fp16, you can drop the support for the other options.
If you make a proposal of what you can keep, I will change the filter header.
Let me know.

RE: Deoldify Vapoursynth filter - Selur - 29.03.2024
I created a new dev version and converted most of the lists to LineEdit-Fields.
This way the logic in the UI is simplified a lot.
Dev version is available under the old link. (includes the .dlls&co since I'm switching to Qt 6.6.3)
=> UI is way less user friendly for the filter this way, but given that the filter has ~50 parameters and probably will get more in the future, that goal died a while ago.
Cu Selur
RE: Deoldify Vapoursynth filter - Dan64 - 29.03.2024
I like your proposal, having grouped the parameters with the same scope helped going in this direction.
I have only the following observations:
1) the lists for filters "Chroma smoothing/stabilizer" start with a boolean flag to enable them.
When the list is checked/unchecked can you automatically change the flag to True/False ?
2) Can you dedicate to the parameter "Darkness" a dedicated GUI params like "Chroma Limiter" ?
Thanks,
Dan
