My rule for a Premiere edit is simple. If the fix has to stay adjustable while the cut is still moving, it lives on the clip or the track as a plug-in. If it needs the spectrogram, the offline quality mode or a module Premiere can't load, it goes to the Editor on a copy of the audio, never on the camera original. The rest of this guide follows that split, starting with the edition question, because your edition decides which of the two routes you even have. If Premiere is only one of your hosts, the [iZotope RX guide hub](https://soundforgepro.com/izotope-rx/) collects the module and host guides in one place. ## How RX fits into Premiere: two routes iZotope lists Adobe Premiere Pro 2026 among the hosts with [confirmed RX 12 plug-in compatibility](https://www.izotope.com/products/rx-advanced?tab=features), next to Audition 2026\. The plug-ins ship as AU, AAX, AAX AudioSuite, VST3, AU ARA and VST3 ARA builds, every one of them 64-bit only, and the [RX release notes](https://www.izotope.com/pages/release-notes/rx-advanced) confirm there has been no VST2 version since RX 11\. Premiere's plug-in manager works with VST3 on both platforms and with Audio Units on macOS, so those are the builds that matter here; the AAX and AudioSuite versions play no part. If VST3 and AU are unfamiliar terms, start with [what a VST plug-in is](https://soundforgepro.com/what-is-a-vst-plugin/). A naming note: Adobe's current help pages call the desktop app Adobe Premiere, while iZotope's host list still says Premiere Pro 2026\. It is the same program, and I simply say "Premiere" below. | Question | RX plug-in in the timeline | RX Audio Editor round trip | | -------------------------- | ----------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------- | | Where the work happens | A clip effect (Effects panel, then Effect Controls) or a track effect (Audio Track Mixer) | The standalone RX application, on an audio file outside Premiere | | What happens to your media | Nothing; settings stay editable and can be bypassed | RX writes new audio; iZotope's own method overwrites the source file | | Editions | Elements, Standard and Advanced | Standard and Advanced only | | Tools available | The VST3 and AU plug-ins in your edition | The Editor's modules, including the three AudioSuite-only tools in Advanced | | Pick it for | Steady problems on clips that may still be trimmed, moved or re-cut | Spectral repair, Best/Offline Dialogue Isolate, Ambience Match, Scene Rebalance, De-rustle, and projects that are getting heavy | RX Connect, the plug-in that sends a selection from a host to the Editor and back, is missing from that table on purpose. iZotope treats Premiere as a host that uses RX as an external editor rather than a Connect host, and the RX Connect section further down explains the Audition detour for anyone who wants that workflow anyway. ## Which RX edition you need for Premiere work RX Standard is the realistic minimum for a Premiere editor, because it is the cheapest edition that gives you both routes. RX 12 Elements is [six plug-ins with no Audio Editor](https://docs.izotope.com/rx12/en/rx-overview.html): De-click, De-clip, De-hum, De-reverb, Repair Assistant and Voice De-noise. That handles hum, clicks and light broadband noise on the timeline, but it has no Dialogue Isolate and no way to open a file for spectral work. Standard adds the Audio Editor plus the plug-ins most dialogue jobs reach for: Dialogue Isolate, Spectral De-noise, Mouth De-click, De-ess, De-plosive and Breath Control, along with De-crackle, Guitar De-noise, De-bleed, Music Rebalance, Monitor, Connect and the Spectral Editor. Advanced builds on that with exclusive tools that iZotope names as [Scene Rebalance, Trim Silence, Ambience Match, Dialogue Contour, EQ matching and de-rustling](https://www.izotope.com/products/rx-advanced). Three Advanced details matter specifically in Premiere: - Ambience Match, De-rustle and Scene Rebalance exist as plug-ins only in the AAX AudioSuite format, which Premiere doesn't load. From Premiere you reach them only by opening the audio in the Advanced Audio Editor. - Only Advanced's Dialogue Isolate has the Quality menu (Good/Real-time and Best/Offline) and the four-band control. ProVideo Coalition's RX 12 review makes the same point about Standard, which gets the module "but only the lower quality mode". - The Advanced Editor opens files with up to 10 channels per tab, while Standard's Editor opens mono and stereo. That matters only if your production audio arrives as multichannel files. ![RX 12 Dialogue Isolate panels for Standard and Advanced side by side: both have Voice, Reverb and Noise faders and a Sensitivity slider; only Advanced adds the Quality menu set to Real-time and the Low, Low Mid, High Mid and High band controls](https://storage.ghost.io/c/af/4b/af4b05d4-2e0b-4edc-8378-1e2a62fecc70/content/images/2026/10/dialogue-isolate-standard-vs-advanced-1.webp) Standard stops at the three faders and Sensitivity; the Quality menu and the four bands are what Advanced adds. US store prices on October 21, 2026: [RX 12 Elements at $99](https://www.izotope.com/products/rx-elements), [RX 12 Standard at $399](https://www.izotope.com/products/rx-standard) and RX 12 Advanced at $1,399, with the Elements-to-Standard upgrade at $299\. Upgrade paths and trial limits are in the [RX price, trial and license guide](https://soundforgepro.com/izotope-rx-price-trial-license/), and the [Elements, Standard and Advanced comparison](https://soundforgepro.com/izotope-rx-elements-vs-standard-vs-advanced/) covers the rest of the ladder. For Premiere work, the deciding line is whether you need the Audio Editor. The current release is RX 12.1.0, out October 15, 2026, which added support for the Boris FX license activation method and changed the product and installer branding. iZotope's RX 12 system requirements list macOS Sonoma 14.7, macOS Sequoia 15.8 and macOS Tahoe 26.x, plus Windows 10 22H2 and Windows 11 24H2. ## Put an RX plug-in on one clip A clip effect is the right home for a problem that belongs to one shot or one take: hum on a single interview setup, clicks in one line, sibilance from one speaker. The settings travel with that clip and stay editable, so a re-trim doesn't cost you the repair. Adobe's [steps for applying effects to clips](https://helpx.adobe.com/premiere/desktop/add-video-effects/apply-video-effects/apply-effects.html) work the same for RX as for Premiere's own processors: 1. Select the audio clip in the timeline. 2. Choose Window > Effects, then expand the Audio Effects folder or type the module name into the panel's search bar. 3. Drag the RX plug-in onto the audio clip. 4. With the clip selected, adjust the plug-in in the Effect Controls panel while you play the clip back. If the drop doesn't take, look at the track's display options: per Adobe's help, an audio track showing Show Track Volume or Show Track Keyframes won't accept effects, so switch that display off first. The plug-ins that make the most sense on a clip are the targeted ones: Voice De-noise, De-hum, De-click, Mouth De-click and De-ess. Repair Assistant also ships as a VST3 and AU plug-in, so it is available on a clip too, not only in the Editor. For many video editors, Dialogue Isolate is the main reason to choose Standard. Its [controls in RX 12](https://docs.izotope.com/rx12/en/dialogue-isolate.html) are Voice, Reverb and Noise gains plus a Sensitivity slider, and the realtime plug-in version has existed since RX 11.0.0 in May 2024\. In Advanced, the Quality menu offers Good/Real-time and Best/Offline. iZotope intends Best/Offline for the Audio Editor and offline renders, and since RX 11.1.0 choosing it inside a realtime plug-in shows a warning, so leave a timeline instance on Real-time and save Best/Offline for the Editor round trip. The [Dialogue Isolate guide](https://soundforgepro.com/izotope-rx-dialogue-isolate/) explains how to balance the three gains. When Dialogue Isolate struggles with a constant noise floor, iZotope's documentation suggests also trying Spectral De-noise, and De-reverb for reverb on material that isn't dialogue. For steady hiss or air conditioning under a voice, the [background-noise workflow in RX](https://soundforgepro.com/remove-background-noise-izotope-rx/) shows when Spectral De-noise is the better tool. ![Premiere workspace map with the Effects panel and its Audio Effects folder marked 1, an audio clip on track A1 marked 2, the Effect Controls panel marked 3 and the Effects and Sends area of the Audio Track Mixer marked 4](https://storage.ghost.io/c/af/4b/af4b05d4-2e0b-4edc-8378-1e2a62fecc70/content/images/2026/10/premiere-rx-placement.webp) Clip effects go from the Effects panel onto the clip and are adjusted in Effect Controls; track effects live in the mixer's Effects and Sends area. ## Run RX across a whole dialogue track When one lav or boom lane carries the same noise through an entire scene, a single RX instance on the track is tidier than a copy on every clip. Adobe documents the [Audio Track Mixer route for track effects](https://helpx.adobe.com/premiere/desktop/add-audio-effects/apply-audio-effects/apply-effects-using-audio-track-mixer.html) like this: 1. Choose Window > Audio Track Mixer. 2. Click the Show/Hide Effects and Sends icon. 3. On the dialogue track, click an Effect Selection icon and choose the RX plug-in. 4. Set its values; the parameters appear in the lower-right corner of the Effects and Sends panel. The Effects Bypass icon in the lower-right corner of the effects list toggles the plug-in for a quick before-and-after, and choosing None from the Effect Selection list removes it. Keep in mind that a track effect processes every clip on that lane, so move room tone, music cues or already clean takes to another track if they shouldn't pass through the noise reduction. One version detail: Adobe's [Premiere release notes](https://helpx.adobe.com/premiere/desktop/whats-new/release-notes.html) list a fix in 26.5 for the Audio Track Mixer's Write automation mode, which had not worked. If you write mixer automation on a dialogue track, be on 26.5 or later; the current release is 26.5.2 from September 2026, with 25.6.6 as the long-term-support line. ## Send audio to the RX Audio Editor without losing the original The Editor route needs RX Standard or Advanced, and the safe version of it starts with a copy. iZotope's [documented method for Premiere](https://support.izotope.com/hc/en-us/articles/47669779037069-How-to-use-RX-as-an-audio-editor-with-Adobe-Premiere-Pro) is short: right-click the clip, choose Reveal in Finder on macOS or Reveal in Explorer on Windows, open that file in the RX Audio Editor, repair it, then choose File > Overwrite Original File. The same page warns that this is a destructive edit and recommends backing up the original audio first. Because the change lands on the source file itself, every sequence and project that uses the file inherits it. I would rather never touch the camera or recorder original, and Premiere already has a tool that makes a clean copy: 1. In the Project panel, select the clip and choose Clip > Audio Options > Extract Audio. Premiere [creates new audio files with "Audio Extracted" in the name](https://helpx.adobe.com/premiere/desktop/add-audio-effects/basic-audio-editing/extract-audio-from-clips.html), keeps the originals, and carries over the clip's channel mapping, gain, speed, duration and interpret-footage settings. 2. Open the extracted file in the RX Audio Editor and do the repair. 3. Write the result to a new file with Save As, or export a WAV at 24-bit or 32-bit float. 4. Import that WAV into Premiere and place it on the timeline lined up with the clip it replaces. 5. Play a few lines against the picture to check sync, then mute or remove the old audio. iZotope's [file-handling documentation for RX 12](https://docs.izotope.com/rx12/en/working-with-files.html) explains why each step is there. The Audio Editor opens WAV, AIFF, BWF, CAF, FLAC, M4A, MP3, AAC, OGG, SD2 and WMA, and from video files it imports only the audio of AVI, M4V, MOV (QuickTime required), MPEG, MPV and WMV, with no video playback. MP4 isn't on that documented list, which is one more reason to extract first. In the Editor, Save overwrites an uncompressed WAV or AIFF on disk, while Save As writes a copy in the same format. An .rxdoc file keeps the original plus every edit but opens only in RX, so Premiere needs a WAV or AIFF export, at 16-bit, 24-bit, 32-bit float or 32-bit integer. ![Flow from a Premiere clip to Extract Audio, the RX Audio Editor, a WAV export, import and replace, and a sync check, with a warning sign on a side branch labeled Overwrite Original File](https://storage.ghost.io/c/af/4b/af4b05d4-2e0b-4edc-8378-1e2a62fecc70/content/images/2026/10/premiere-rx-copy-round-trip.webp) Repair the extracted copy; the Overwrite Original File branch changes the source media for every sequence that uses it. Two more habits keep sync intact. Don't cut or close gaps in RX on a file you plan to line up again, because a shorter file no longer matches the picture; leave Trim Silence and other time edits for audio with no picture to follow. And if a cleanup leaves lines sitting on dead silence, [room tone fills](https://soundforgepro.com/room-tone-sound-forge/) are the fix, with Ambience Match as RX Advanced's tool for that job. Vegas Pro users get the same copy-first logic in the [Sound Forge and Vegas Pro round trip](https://soundforgepro.com/sound-forge-vegas-pro-workflow-video-editors/). Premiere's Render and Replace is not a shortcut for any of this. Adobe documents it as a way to [flatten video clips and After Effects compositions for playback](https://helpx.adobe.com/premiere/desktop/render-and-export/render-sequences-for-playback/render-and-replace-media-in-a-sequence.html), with Restore Unrendered to go back, and it is not part of iZotope's audio route. ## Why RX Connect isn't the Premiere route RX Connect does not give you a round trip inside Premiere. The [RX Connect FAQ](https://support.izotope.com/hc/en-us/articles/47669779599629-RX-Connect-FAQ) lists its hosts as Pro Tools 10 and later, Media Composer, Audition, Cubase and Nuendo, and groups Premiere Pro with the hosts that use RX as an external editor. That external-editor workflow is the copy path from the previous section. If Audition is installed, iZotope describes a detour: choose Edit Clip In Adobe Audition from Premiere's timeline, then use RX Connect inside Audition. There, Connect works only as a VST3 plug-in because the AU version isn't functional, and iZotope's [Connect steps for Audition](https://support.izotope.com/hc/en-us/articles/47669813860237-How-to-use-RX-Connect-in-Adobe-Audition) run like this: switch to Waveform view, select the audio, choose Effects > VST3 > Restoration > iZotope and pick Connect, click Apply, repair the audio in RX, click Send Back, then reload Connect and Apply again. A setting in Premiere's [audio preferences](https://helpx.adobe.com/premiere/desktop/get-started/preferences-and-settings/audio-preferences.html), Render Edit in Audition files to, decides whether those files land on the captured-audio scratch disk or next to the original media. The detour pays off mainly if you already finish audio in Audition; otherwise it adds a second application to a job the copy path handles on its own. The [RX versus Audition comparison](https://soundforgepro.com/izotope-rx-vs-adobe-audition/) covers the Connect workflow there in more depth. ## Test results: what published comparisons show Across seven dialogue scenarios in two ProVideo Coalition comparisons, RX Dialogue Isolate won or shared four and Adobe's web Enhance Speech won or shared four, one of them a context-dependent tie. The Enhance Speech built into Premiere won none of the three 2026 scenarios and trailed the web version in all three. All three editorial sources behind this summary conclude that no single tool wins every recording. | Scenario | Published comparisons | Result | | ------------------------------ | --------------------- | ------------------------------------------------------------------------- | | Steady background noise | 2 | RX won 2 of 2 and was judged truer to the original voice | | Poor phone recording | 2 | Web Enhance Speech won 2 of 2 | | Busy street or heavy traffic | 2 | Split 1–1: RX 11 shared the 2024 win, web Enhance Speech won in 2026 | | Camera focus noise | 1 | RX 11 or Enhance Speech V2, depending on context | | Enhance Speech inside Premiere | 1 (three scenarios) | Won 0 of 3 and trailed the web version in 3 of 3 | | Eight-tool dialogue shootout | 1 (four examples) | RX placed second once, third twice and fourth once; median third, no wins | The most recent comparison is ProVideo Coalition's [RX 12 shootout from May 1, 2026](https://www.provideocoalition.com/izotope-rx-12-shootout/), a headphone listening comparison of RX 12 Dialogue Isolate against RX 11 and against Enhance Speech both online and inside Premiere. RX 12 won the steady-noise test and a separate Scene Rebalance test; the web Enhance Speech won the phone recording with room reverb and the heavy-traffic clip. On the first test the reviewer called the web version "MILES better" than the one in Premiere, and he summed up Premiere's built-in Enhance Speech as one that "remains very patchy" next to the online version. The [Enhance Speech V2 comparison from November 29, 2024](https://www.provideocoalition.com/adobe-enhance-speech-v2-tested/) points the same way. RX 11 Dialogue Isolate won steady noise, Enhance Speech V2 won the phone recording, RX 11 and Waves Clarity Vx shared the busy street, and camera focus noise was a draw that depended on context. The reviewer added that he would keep RX if he could keep only one tool. Production Expert's [2025 dialogue noise-reduction shootout](https://www.production-expert.com/production-expert-1/dialogue-noise-reduction-shootout-2025-the-results) sets a harder bar: eight tools and four examples, with RX Advanced's Dialogue Isolate processed in Best/Offline mode in Pro Tools. RX placed second once, third twice and fourth once, a median of third, and the write-up concluded that RX "is no longer the dominant tool". The winners were three newer processors: Hush Pro, dxRevive Pro and Supertone Clear. The conditions differ, so read the counts as reviewer verdicts rather than a single score: ProVideo Coalition compared tools by ear on headphones, and Production Expert ran processed examples from a Pro Tools session. The one Premiere-specific data point is the built-in Enhance Speech, and it came last against the web version every time. My reading for an editor: RX is the safer bet for steady noise and for keeping a voice sounding like itself, the web Enhance Speech is the strongest rescue for phone-grade recordings, and the Enhance Speech inside Premiere is the weakest of the three in these results. ## When RX misbehaves in Premiere Start with the plug-in scan, because most of the other cases below are single-user reports that are worth knowing before a deadline rather than known bugs. Generic fixes for scanning, folders and blocklists sit in the [RX plug-ins not showing checklist](https://soundforgepro.com/izotope-rx-plugins-not-showing/); this section covers the Premiere-specific part. ### RX doesn't appear in the Effects panel Open Premiere's Audio preferences and choose Manage Audio Plug-ins. Adobe's [audio preferences reference](https://helpx.adobe.com/premiere/desktop/get-started/preferences-and-settings/audio-preferences.html) describes it as the way into the Audio Plug-in Manager for third-party VST3 plug-ins and, on macOS, Audio Units. Depending on the version and OS, the top menu reads Settings or Preferences. Run Scan for Plug-Ins there. If an RX module is still missing, check three things before reinstalling: - RX 12 has no VST2 build, so a legacy VST folder is the wrong place to look. - Ambience Match, De-rustle and Scene Rebalance are AudioSuite-only and will never appear in Premiere's list. - Elements installs only its six plug-ins; Dialogue Isolate and Spectral De-noise come with Standard. Exports through Adobe Media Encoder need their own scan. With Import sequences natively turned on, Media Encoder renders third-party VST3 effects (and AU on macOS) itself, and its [separate Audio Plug-in Manager](https://helpx.adobe.com/media-encoder/desktop/encoding-quick-start-and-basics/adding-third-party-plugins.html) sits under File > Manage Audio Effects. Use Scan for Plug-Ins after a fresh install, Rescan existing plug-ins after an RX update, and Reload for an entry marked Not Working. Its folder list is for legacy VST only, so don't add the VST3 folder there. ### A beta build finds no plug-ins In one Adobe community thread, a user on macOS 26.5.2 reported that [Premiere (Beta) 27.0.0 scanned zero third-party plug-ins](https://community.adobe.com/bug-reports-733/audio-plug-ins-still-missing-1637072), while the release Premiere Pro 2026 on the same Mac loaded RX and the rest. Projects saved in the beta also wouldn't open in the release build. My advice is to keep RX jobs in the release version, currently 26.5.2. ### The plug-in window is cropped After updating Premiere from 24.6.3 to 25.2.3 on Windows 11, one user reported the [RX 11 Repair Assistant window appearing cropped](https://community.adobe.com/bug-reports-728/izotope-rx-11-and-premiere-pro-25-2-3-1331563). What worked for them: temporarily switch the display to 1920x1080 at normal scaling, load the plug-in, then switch back. ### Projects get slow or exports fail One user on the Native Instruments community described a Premiere project with [many RX 11 De-noise and Repair Assistant instances](https://community.native-instruments.com/discussion/50991/rx11-causing-memory-leak-in-premiere) that opened slowly, ran out of memory on a 96 GB machine and crashed exports, while a copy of the project without the iZotope plug-ins opened normally. Once a clip's fix is settled, I would print it to a WAV through the Editor copy path and remove the live instance. If RX crashes outside Premiere as well, the [RX crash and won't-open fixes](https://soundforgepro.com/izotope-rx-keeps-crashing-wont-open/) are the next stop. ### Playback lags behind the picture Realtime Dialogue Isolate carries latency. One user reported [85.3 ms for RX 12 against 42.3 ms for RX 11](https://community.native-instruments.com/discussion/50782/rx-12-dialogue-isolate-latency) in Live Professor 2, a different VST host, not Premiere. Native Instruments staff replied that Dialogue Isolate works best offline in Best/Offline mode in the RX Editor, that the plug-in is a convenience, and that the host has to compensate for the latency. If voices drift against lips during playback, that is one more argument for the Editor route on the problem clips. ## When Premiere's own tools are enough For a quick social cut with a reasonably clean voice, Premiere's Essential Sound panel may be all you need; for client delivery or a voice that has to stay natural, I would reach for RX. Premiere's [Enhance Speech feature](https://helpx.adobe.com/premiere/desktop/add-audio-effects/adjust-volume-and-levels/enhance-speech.html) lives under Essential Sound > Enhance, processes in the background and has a Mix Amount slider for blending the enhanced and original audio. The [Repair options in Essential Sound](https://helpx.adobe.com/premiere/desktop/add-audio-effects/adjust-volume-and-levels/repair-dialogue.html) offer Reduce Noise, Reduce Rumble, DeHum, DeEss and Reduce Reverb, each on a 0–10 slider. The published results above favor the web version of Enhance Speech over the one inside Premiere. ProVideo Coalition's [RX 12 shootout](https://www.provideocoalition.com/izotope-rx-12-shootout/) describes the free web tier as audio-only, one file at a time, with no strength slider, a limit of 30 minutes and 500 MB per file and one hour a day; Premium, included with Creative Cloud or Express Premium, adds video uploads, batches and the slider. Adobe is also previewing Enhance Audio in the Premiere beta. A [sponsored ProVideo Coalition explainer on Enhance Audio](https://www.provideocoalition.com/stem-separation-moves-into-the-edit-what-enhance-audio-changes-for-dialogue-workflows-in-premiere-beta/) says it separates speech, music, ambience, effects and reverb on-device, with the voice enhancement running locally on Enhance Speech V1 or in the cloud on V2 at two generative credits per minute. It is a beta feature, and none of the comparisons above includes it. - **Premiere's built-ins:** a talking head with mild noise, a social cut on a deadline, or a rough cut that goes to a mixer anyway. - **RX on the timeline:** steady noise, hum, clicks or sibilance where the voice has to keep its character. - **RX Audio Editor:** anything that needs spectral repair, Best/Offline quality or the Advanced-only modules. - **Web Enhance Speech:** a phone-grade recording you can't replace, where intelligibility matters more than tone. ## My recommendation For most editors cutting in Premiere, I would buy RX Standard. It puts Dialogue Isolate, Spectral De-noise and the targeted repair plug-ins on the timeline, and it adds the Audio Editor for the clips that need more than a plug-in can give. Premiere Pro 2026 is on iZotope's confirmed host list, so the plug-in route is a supported one rather than a workaround. I would pay for Advanced only if you need Best/Offline Dialogue Isolate, Scene Rebalance or Ambience Match and are ready to use them through the Editor, because Premiere can't load the AudioSuite-only modules. Elements makes sense only if your problems are hum, clicks and light noise that six plug-ins can handle on the timeline. Whatever the edition, leave the original media untouched: extract, repair a copy, bring a WAV back. And keep the web Enhance Speech in reserve for phone-grade recordings, the one scenario where it led both published comparisons. ## FAQ ### Can RX open the MP4 files from my camera? MP4 isn't on RX 12's documented list of video formats, which covers AVI, M4V, MOV, MPEG, MPV and WMV, and even for those RX imports only the audio. Extract the audio in Premiere first and open the extracted file in RX. ### Can I try RX on a Premiere project before buying? Yes, with limits. The [RX 12 Standard trial](https://www.izotope.com/pages/product-downloads/rx-standard) runs with export disabled for 10 days, and after that Demo mode inserts silence at regular intervals. Treat it as an evaluation, not a way to finish a delivery. ### Does the RX Spectral Editor work inside Premiere? Not as a plug-in. iZotope's RX 12 release notes list Logic Pro 10.7 and later (AU ARA, under Rosetta only) and Studio One 7 or Studio Pro 8 (VST3 ARA) as the Spectral Editor's ARA hosts, and Premiere isn't among them. In Premiere, spectral work happens in the standalone Audio Editor. ### What did RX 12.1 change for Premiere users? The 12.1.0 update from October 15, 2026 added support for the Boris FX license activation method and changed the product and installer branding. If the plug-ins disappear from Premiere after any RX update, rescan them in the Audio Plug-in Manager, and use Rescan existing plug-ins in Media Encoder.
