I'm looking for a replacement for Javinizer but primarily want to rename the files to have actress name and release date in them, not so much scrape posters, plot, etc.

You mean rename the folders, or just the video file name? By default the video folders have title, studio, ID, and actresses in them. However, if you want the power to customize your folder naming, you would need to Patreon version to do that.

As for video file naming, by default it uses content ID. There is an override to use DVD-ID or Original (no change), but nothing that allows you to modify the naming convention (at least as extensively as folder renaming). This is specifically because video file names have special meanings in regards to its associated metadata, so most people leave it as the default content ID (strongly recommended).
