Help using ML Timewarp

I’m using ML Timewarp to speed up a custom FX ribbon TW on a long sequence so I’ll be rendering overnight. What is the “reduce flow res” button for, and what is the difference between the two “models” modes (1.8 and 2.4). I see in Randy’s tutorial the “reduce flow res” is turned on, but it isn’t turned on by default for me… thanks!

Great question Renee. I’m doing some really challenging dupe-frame fixes and the first pass on TWML is too mushy to use. Will changing these settings sacrifice resolution and/or accuracy, but produce a more useable result? Obviously I’m going to try every combination anyway :slightly_smiling_face: but it would be good to know what’s happening with the algorithm. @talosh ?
