I've been doing trial and error on different applications and I think I'm close. I think I've figured out the problem that had halted my authoring and I might be close on a breakthrough on the 24fps progressive mpg encode. I've learned so much about encoding the last week or so it's scary. I know exactly what I want it to do, and I think I almost have TMPGEnc bent to my will. TMPGEnc is just so freakin' slow that it takes forever to see the results of the latest trial. Each one gets closer.
