Premiere Pro Keeps Creating .prin Files – What Are They and Can I Stop It?

Question

Hi Adobe Community,I've noticed that Adobe Premiere Pro keeps generating .prin files in my project folders. I'm not entirely sure what these files are for. They seem to appear after saving or sometimes even while I'm just working on a project.A few questions I have:What exactly are these .prin files?Are they necessary for my project workflow?Is there a way to prevent them from being created, or at least have Premiere clean them up automatically?I'm using [insert your version of Premiere Pro] on [your operating system], and this has been a consistent issue for me. It's cluttering my project folders, and I want to make sure I'm not doing something wrong.Thanks in advance for any help or clarification!Best regards,

Thank you for your feedback.These files are part of the new media intelligence feature which powers the visual search in Premiere Pro. Premiere Pro analyzes all the video data in your project and creates a search database from the visual information. If you then hit the "search" button in the top right of the header bar you are e.g. able to search for complex expressions like "drone shot of a red car in a city"The media intelligence settings to enable/disable this feature are available on the import page or through the app preferences.See more details about media intelligence here: Adobe Helpx - Premiere Pro Media Intelligence SearchHope this helps - and happy searching!Best regards, Alexander

I realize this is an older thread but I thinkthe .prin file stores all kinds of info related to AI features in Premiere. So…even if you delete it, or turn off Media Analysis, this file will get recreated if, for example, you usedan AI feature in your Premiere project, such as Scene Edit Detection, or Enhance Sound, or Remix Music, or Auto Reframeto 9x16, etc. I don’t know why anyone would want to NOT use media analysis because it enables the use of the Search panel which is amazing (for me anyway). The .prin file enables faster performance in Premiere, and keeps the Project file itself lighter by storing AI info in a separate sidecar file. If you used any AI features in Pr, then delete that .prin file (or moved the project and don't take the .prin file too) then your performance in Pr will be temporarily slower when you re-open that project...while it rebuilds the .prin data so your enhanced speech or remix track orAI Masking effect works correctly every time without having to use more resources to recreate it the next time your playhead hits it. Hope this helps!
