The following are the new model -m options which fixes VEAI opening and doing nothing. Unfortunately -o is broken in so many versions of VEIA, I have given up . The following should help you get around Topaz team old documentation. Matt posted that the Topaz VEIA team have put veai commandline as low low priority, which is unfortunate when they were so close to having a fully functional command-line interface which could have been used to interact with other video applications. I hope they invest more time in systems that have resources, Intel Xeons, Ryzen, Threadripper, Eypc with multiple GPUs.
