Topic: The Intro to the movie Hugo test not using RIFE

With my previous non RIFE settings I forgot to test the intro to Hugo which is a brutal test of difficult scene changes and slow pans. If you have a large screen then you might not see the nano stutters, but with the wrong settings you will see the micro stutters. My settings failed the Hugo test but it taught me that I turned up almost every setting up to max increasing complexity, making SVP more likely to be the bottleneck. I also came across another artifact in Alita that I haven't noticed before.  The main fix seems to be increasing vector block sizes to 32 which also reduces complexity but is potentially less accurate. I had already overridden the main search to SATD but I also returned the PEL quarter pixel override.  Both of these increase computation complexity but they also increase accuracy. Then I reduced the complexity of the ancillary settings including removing SATD from the search radius. More smoothness was achieved from using SADT in the main SVPAnalyze than making changes to the lesser settings.

The new settings are shown below. If you have seen my other settings then the changes will be obvious. Even with these settings the Hugo intro still has some nano stutters but I don't think most people will see them. For the "advanced" changes I have attached the relevant sections from the manual below the main SVP manager window. PEL is not included but it's on the same manual page. These settings are very advanced so anyone trying them should be careful.

Re: The Intro to the movie Hugo test not using RIFE

SATD really smooths motion and helped a lot with Hugo. But it caused other issues which I'm certain wouldn't be a problem on a TV but are apparent on a large screen. Basically SVP becomes the bottleneck. So I removed SATD from main search, reduced the vertical block size back to default and tweaked the other settings to get as close as possible to SATD smoothness. But this still left the Hugo intro a bit choppy. The final piece of the puzzle was using merge adjacent frames to smooth out the stutters. This combination gives me SATD like smoothness but without SVP showing subtle signs of being a bottleneck.
