This is what I've been using up to now works with VP17 aok. Just change the 15/16 to 16/17 as needed.
Mercalli ... Copy these 2 folders to VP16 to get ProDad Mercalli working ... C:\Program Files\VEGAS\VEGAS Pro 15.0\OFX Video Plug-Ins\proDADMercalli4CmosFixr.ofx.bundle\ C:\Program Files\VEGAS\VEGAS Pro 15.0\OFX Video Plug-Ins\proDADMercalli4Stabilizr.ofx.bundle\
Pluraleyes ... Copy the file "PE4Vegas14.dll" which is in the folder .. C:\Program files\Red Giant\Pluraleyes 4\ then paste it to ... C:\ProgramData\Vegas Pro\Application Extensions\
or ... "PE4VegasLoader14.dll" rather than "PE4Vegas14.dll"
Downloaded the ProDad Mercalli demo but have installed & removed 4 or 5 times and still no plugins in Vegas Pro 17 for me. Unfortunately I have no prior installations so nothing to copy.
Yep and it has a MAGIX or VEGAS installer - tried both (a few times now) and neither gives me anything within Vegas, on the plus side, SAL works. Just wanting to evaluate whether it's going to work for me (for the kind of footage that I want "fixed". On the first attempt in SAL it seemed to improve things but not to the extent of immediately reaching for my credit card (and the plugins not working doesn't fill me with confidence).
