I’ve got SpicemasterPro 2.5 and it is working fine in VP9b 32-bit on XP Pro SP3. I have it working in previous versions of VegasPro and this new iteration of Vegas has just picked it up and is working as it should.
When you say: “I just recently acquired a plug-in for Sony Vegas called, “Spicemaster.” ” – did you download it from the Pixelan website? And if so, did you go through the installation process? If you did, and you aren’t satisfied, then I would be going back to Pixelan: https://www.pixelan.com/sm25/intro.htm : and querying them.
Also, this is a useful page on their site: https://www.pixelan.com/sm25/help-techsupportfaqs.htm
I have many plugins from 3rd party developers, and all have worked. Spicemaster is a highly professional set of tools. Get back to them and I am sure they will assist.
