What is a .prin file?

[MisterAdvent]

With build 58, I notice a .prin file is created with the project. Windows says it's an "Adobe Media Intellegence Project Index File."

What's that supposed to do???

There is definitely a slow down in performance when the system is processing data for the .prin file. I find the following behaviours as PPro is "Auto-tagging Audio", "Transcriptions", and "AI Image Search":

- In the timeline, when I press play, playback is delayed on average 3-5 seconds. 

- sluggish response to various commands such as scrubbing the playhead, opening a clip or sequence, navigating the project panel. 

Granted, I'm working with various formats from MP4 to 4K MXF from a Canon C500. However, when I turn off some of these tasks, such as Auto-Tagging Audio and Transcription, performance improves dramatically. I'm on a pretty fast machine, specs below. 

Mac Pro M2 ULTRA 24C CPU, 76C GPU

128GB Memory

2TB SSD

32TB 8-Bay Promise Pegasus via Thunderbolt

Media Cache is going to a 1TB Samsung SSD Pro, internally mounted

Hope this helps.

This is really annoying, the toggle doesn't work, every time I delete the file, it is being generated back again... 

Just save the file where all the cache is. Why should it be a project folder? It's a useless file anyway.

Thank you for your feedback.
The prin file is used by Premiere Pro to power the new visual search feature. It contains the visual information of all the assets and sequences in your project. It is saved next to your project as a way for you to e.g. share or archive your project including this index, so Premiere Pro does not have to re-analyze all the assets again. It is a bit different from data we put into the media cache as this is already condensed and closely related to the current version of your project (e.g. it is kept up to date to only contain the data you use).

The prin file will not be created after you disable media intelligence and clear the media cache.

When I used the search function, it wasn't even good..
It's more accurate to just search in the Sequence window.

get rid of it....creating a nuisance

Works for me - thanks!

Hi Alexander. I use CreateStudio for some minor characters (to change it up from Adobe Animator's). I dragged it in to my timeline just fine, that is to say, with video and audio. I temporarily deleted it on account of inadventenly covering over a track I had worked on; the dragged it back into to the end of my timeline; but now the .prin thing has suddenly made the video portion unusable. If i delete it and drag again, or restart, or drag it elsewhere, it's the same. Is this some sort of a hit against CreateStudio so we don't use it. I hope it doesn't happen with my Toonley characters as well. A lot of goes into these .mp4 tracks that i need to use in my cartoons that are assembled in Adobe's Ch, Au, and PPro. thanks!

Another vote here to give Prin files their own folder. Very distracting.

Hi there, 

I came across this thread and wanted to chime in - I was having trouble with Premiere freezing up and giving me the beach ball when I was trying to "Replace Clip with After Effects Composition" 

And after I turned off the "Analyze all imported media..." option, the replace with AE Composition started working again. 

Echoing the others, please do not enable these new AI features by default Adobe!!

I have the same question...

I also vote for these files to go into their own folder, just like auto-save or cache files. Please and thank you.

Don't worry y'all.  They're gonna get it fixed at the same time the tackle the "Adobe Premiere Pro Audio Previews" folder issue.

[Carefree_Eagle9543]

This is mad annoying

[KG500]

In case anyone is still folllowing, I spoke with Adobe support and their "fix" is to go back to version 25.0.0. 

[Alexander_DVA]

See the answer that was marked as correct - there is no need to downgrade if you dont want to use that feature. If can just be disabled in the preferences and will no longer be used after clearing your media cache.

[icedcoffee00]

no, it still creates prin file. I followed all the steps in this thread. Very annoying

Just wanted to say, after a couple of months of allowing .prin files etc, I found that yes, it does slow PPro down when it's analyzing etc, but once it's done, it's back to normal. After you allow yourself some time to let the application do this, you're GTG. 

It makes only one .prin file per the most active project file. So, IMO, not as messy as I thought it would be at first. And I've been using the AI search feature, and in projects with large amounts of source files, it has become handy at times. It's not perfect of course, and definitely leaves much to be desired, but it works enough that I've found it to be helpful. 
So, for the time being, I've come to terms with these additional processes and resulting file. Just give it a try and you might come to the same conclusion.
