Played around with it, results were so so... then I removed it from the Plug-in Video FX chain yet it still insists that I hit the Analyze button. I validated there is no Mercalli FX used in any of the clips on my timeline, yet all I get is Analyze :(
Yes, Vegas Pro 14, haven't found a good repro scenario yet. Even deleting and adding the video track back in doesnt fix the issue - I would hate having to abandon the whole project :(
