Update the supported Rife versions

[Groudonx]

I've heard that Rife optimizes for anime scenes in the version 4.7.

The latest frame interpolation rife version supported by video2x seems to be 4.6 (this shows up for me in the list on Windows).

I think it would be nice to include these newer versions of Rife for a better output quality.

Thanks for the heads up, I didn't know they released a new version. I'll check it out.

I'm actually not sure where the new models are released. The ones that are currently included are from https://github.com/nihui/rife-ncnn-vulkan. Could you please give me a link to where you saw the 4.7 model?

Maybe he means this: https://github.com/hzwer/ECCV2022-RIFE
There is Something with Rife 4.7-4.10

I only heard about if, unfortunately I'm not very well versed on the technical side of things.

The Rife Vulkan Github you linked has the open issue nihui/rife-ncnn-vulkan#66 so I'd assume it's not included there yet. The issue was opened more than a year ago, which lead me to believe that this Rife version may be accessible by now.

@Pete4K Yup thanks. I saw that repo but I didn't find the download links. It turned to be in https://github.com/hzwer/Practical-RIFE/tree/main#model-list. The models appear be in flownet pytorch format. We'll need to convert them to ncnn somehow.

Hi k4ty3k, I'm trying to convert 4.26 RIFE model to ncnn format, got a bin file and a param file. However, I installed the video2x using deb file, where should I put the model file so that I can test the converted model?

[k4yt3x]

@B1ACK917 it should go under something like /usr/share/video2x/models/rife/rife-4.26. However the CLI argument parser won't recognize the new model, you can try replacing the files of an existing model

[Pete4K]

Btw, does Somebody know how I can train models? I would like to train the Real ESRGAN Anime Plus model vor Videos and maybe more frames/sec. I don't know If I have to do Something with Programming Languages, because I'm bad with it.

@k4yt3x After some attempts, I found the 4.2x model is quite different from v4.6, so I need to fit some code and recompile the project to test, lol. Now I have added the support for 4.25, 4.25-lite and 4.26, but I need to change the librife code, because version > 4.6 changed the padding and add a memorydata layer, so I will first open a PR in that librife repo, I'm on it, please check it later.

Thanks for the PR. I've tested and merged it. It seems to work well:

I'll proceed to adding this model to the GUI.
