That would be fantastic Mayday. Since you have a lot of knowledge, I would really appreciate your guide…even a small one.
Thank you for your quick response, this would be awesome! I have some older vids and struggling to find the right method as the results often tend to end unnatural with Iris or also when using Rhea.
I think I got here eventually. Typical of a first post! 
Looking forward to your post on your process. Thanks
Any update?
I use SeedVR first, Starlight Mini next and Proteus Natural as a final step.
starlight takes forever
So a lot has changed. My post referred to the time before we got Starlight, when you could achieve better results by overlaying in a video editor two upscales done with different models.
Now it’s more complicated because there is no workflow that fits every source. As Urix wrote, as a final step Proteus (Natural) or Iris MQ are good finishers. I mostly use them without a 1x upscale, and this is also the step where I add Gaussian grain and optional frame interpolation.
I wrote some combinations that works next days
Brother those are just perfect. But after those three what to choose to upscale, cause still watching 480p on 1080p screens or higher its blurry, not as much of course but still
Certainly, but i cant let my laptop for 20+ hours to process a video. Im working from it. If i had a desktop i would have done it. Thats the main reason im asking for an alternative workflow to achieve decent results.
I have got a new suggestion. This is valid for 512x384 and 640x480 highly compressed MPEG-4 ASP SD videos from the Early 2000s.
Step 1: Upscale the video with Starlight Precise 2.5 to minimum 720p resolution, export is DnxHR HQ mov for example(my choice)
Step 2: Upscale the mov upscale now with Starlight Sharp to the desired resolution(for example 2x or 3x) and export into the desired final format(for example H.264 mp4 with dynamic bitrate and High quality setting is my preferred choice)
Starlight Precise does all-in-one: not so blurry as Mini and not so crisp as Sharp.
I’ve dumped both models in favor of Precise, and Iris afterwards.
Exactly. Or - if you have too much time - SLP and SLM afterwards.
It does not quite do it all because it often amplifies noise on SD video material and enhances details but those details remain soft. That’s where Starlight Sharp comes in - it perfectly cleans up that noise and makes those extra details more defined around their edges.
Any update on your combinations that you told gonna wrote about?
