This isn't an issue (or even really a priority at the moment), I'm just curious and thinking ahead.
With UXP development really starting to kick into gear and beginning to be accessible, and with the eventually depreciation of CEP; do you have any plans in the future to support UXP?

This repo has become so invaluable to me and my workflow and it would be a shame to be locked to a version of premiere in the future due to CEP depreciation. (plus with the benefits of UXP it'd be unfortunate to not be able to take advantage of them)

Thank you for your time, again, no pressure in any form, just curious!

    The good: UXP is a more modern framework that gets rid of the client/server split and just offers a simple way to define scripts, so it should be comparably easy to work with (or at least way easier than CEP, which is like legacy by design).

    The bad: Currently, UXP for Premiere is limited. Looking at the available documented functions of the Premiere DOM, it seems that CEP is still way more powerful. AFAIK, Premiere is no priority for Adobe, so this still might come.

    I would postpone a complete re-development of PremiereRemote until either
    a) The UXP Premiere DOM is more comprehensive and offers an actual improvement over CEP
    b) CEP is not supported anymore and kicked out of Premiere, which may happen sometimes between 2026-2028, depending on how to interpret this.

    Unfortunately, when I started development in 2018, I also had way more time then today (I was a student back then, now a full-time software engineer). So although I'm willing to update (or redevelop) this tooling, I might not be able to. Not the promising answer you may have hoped for, but at least an honest one ;)

    So, I first did a manual feasibility study and then an automated one using Claude AI. I was worried that the UXP DOM ist still very limited, but fortunately, this seems to be wrong. This changes my perspective, and I might rewrite PremiereRemote some time later this year.

    I attached the results.

    Migration Impact Assessment

    High Severity - Complete Feature Loss (9 methods)

    • Quality Engineering (QE) API: Entire qe.* namespace unavailable
      • Affects: setLockedForAllTracks, unlockTracks, applyDropShadowPreset, applyBlurPreset, applyWarpStabilizer
      • Impact: Advanced effect application and track locking functionality lost
    • Track Targeting System: No targeting concept in UXP
      • Affects: targetAllTracks, untargetAllTracks, targetDefaultTracks, targetTracks
      • Impact: Track targeting workflows must be redesigned using selection-based approaches
    • Direct Frame Rate Access: No videoFrameRate.ticks equivalent
      • Affects: addCustomMarker, selectCurrentMarker
      • Impact: Custom timing calculations need alternative approach

    Medium Severity - Workaround Required (8 methods)

    • File System Operations: UXP uses different permission-based file APIs
      • Affects: loadMarkersFromCSVFile, saveCustomMarkerToTextFile
      • Solution: Migrate to localFileSystem API with proper manifest permissions
    • User Notifications: alert() requires manifest configuration
      • Affects: addCustomMarker
      • Solution: Enable enableAlerts feature flag in manifest
    • Project State Detection: Different approach for checking document status
      • Affects: zoomCurrentClipToFit
      • Solution: Use Project.getActiveProject() to verify project availability

    Low Severity - Direct Migration Available (58 methods)

    • Core Premiere Functionality: Most sequence, track, and clip operations supported
    • Action-Based Architecture: Property changes use createXXXAction() pattern
    • Async/Promise Pattern: Methods return Promises instead of synchronous values
    • Component System: Effect manipulation via ComponentChain and ComponentParam

    The loss of qe is definitely a tough pill to swallow, it's especially frustrating that anytime I see anyone mention a qe function and how losing it with UXP will impact them the default response from adobe is along the lines of; "well, it wasn't supported, don't understand why you'd need it, oh well". I wish they were a bit more open to hearing usecases for some of the functionality it offers/offered. ie
    I believe ivan has mentioned having no access to track locking as well - shame it received no response.

    I am glad to hear you're interested in providing UXP support, that's great news. I do hope adobe continues to expand UXP into the future and don't just stop short once they've achieved "backwards compatibility"

    Just a heads up, I'm currently rewriting PremiereRemote from scratch to support the new UXP framework (and get rid of many many many problems the original implementation had). The UXP branch contains a funtional but very, very early version - but the core functionality of making arbitrary UXP functions executable via HTTP calls is already there :)

    I finally had some free time recently to sit down and attempt to get the ball rolling with my own setup. It took me the better part of half a day just to figure out how to get the uxp plugin to actually appear in premiere (and then almost as long to figure out how to update the plugin once I've added functions or made changes lol) but once that was sorted things started working a little smoother 😅
    Currently in the process of porting as many of my own functions over to uxp just to get a feel for things and I'm loving things so far!

    That's great to hear! As soon as the initial development is done, I will of course invest in better documentation (well, more than 0 documentation :D). I see a lot of potential in providing a unified yet customizable interface usable both for manual and MCP-based workflows. Adobe did also some baby steps here, but far more limited than what direct UXP manipulation can reach.
