When Create Proxies is greyed out, Premiere is telling you the clip you selected fails at least one of four eligibility conditions — and Adobe publishes all four in a single sentence. That sentence is short enough to check against your Project panel in under a minute, which makes this one of the faster Premiere problems to diagnose once you stop guessing.
The guessing is the problem. Search this and you get advice about drive speed, codecs, 4K, and cache clearing. Adobe's own create-proxies page says none of that. It says this:
"You can create proxies only for video clips without captions. Proxies are not supported for any other types of files or growing files. The media must also be online."
Four conditions. Nothing else on that page adds a fifth.
What Premiere is actually checking
Adobe restates the same rule a second way on the same page, this time in terms of project items rather than clips:
"Premiere can create proxies for master clip project items if they have video, have no captions, and are not growing files. The media must also be online."
Reading both sentences together gives you a checklist that maps onto things you can see:
| Condition | What fails it |
|---|---|
| Has video | Audio-only files, stills, anything without a video stream |
| No captions | A clip carrying captions |
| Not a growing file | A file still being written to |
| Media is online | Anything showing as offline in the project |
Work down that list against the specific item you selected, not against your footage in general. The rule is written per project item, which matters more than it sounds like — see the next section.
The fastest check: what did you actually select?
Start here, because it is the most common false alarm.
Adobe describes what happens after a successful command like this: "A proxy job is then created in Adobe Media Encoder for each of the project items chosen that can be proxied, and an offline proxy is attached to each project item."
Note the qualifier — "that can be proxied." Eligibility is evaluated per item, so a mixed selection is not a single yes-or-no. If you right-clicked a bin, or lassoed everything in the Project panel, you have almost certainly included something that is not a video clip. Select one clip you are confident about — a plain camera file with video, fully imported, showing online — and see whether the command comes back.
If it does, the problem was never the clip you were thinking about. It was the company it was keeping.
Condition by condition
Captions. This is the condition nobody expects, and it is listed first in Adobe's sentence. A clip with captions is not proxyable, full stop. If you have already run Speech to Text or imported an SRT against that media, that is the thing standing in your way. Adobe's captions overview has a warning worth reading before you start deleting things to get around this: "Add captions when your edit is finished or close to finished. Although, you can fine-tune and edit along with a caption track, if you delete caption segments, you'll need to recreate them manually to restore a part of a clip to your final edit." Deleting captions to unlock proxies is a trade, not a free fix.
Not a video file. Adobe's wording is "Proxies are not supported for any other types of files." The companion page on attaching proxies is more explicit about which types those are: "You can attach proxies only for video-only, audio/video, and offline clips in the Project panel. Other file types (for example, audio-only, stills, or image sequences) are not supported." Music beds, logo PNGs, and image sequences are all on the wrong side of that line.
Growing files. A growing file is one still being written. If you are working against media that a recorder or a transfer is still filling in, Adobe lists that as unsupported — wait for the write to finish and try again.
Media offline. "The media must also be online" is the last clause, and it is easy to miss when a bin shows a mix of states. Relink first; proxy second.
When the clip simply is not eligible
Some of these you can clear. Others you cannot — an image sequence is never going to become a video clip, and a file that is mid-write just needs time.
The reason you wanted proxies in the first place still stands, though: heavy source media makes editing painful. Where the proxy system refuses to help, making a lighter copy of the file yourself does the same job by a different route — a smaller, lower-bitrate version you can cut against, with the original kept aside for the final export.
Try it right here
Runs in your browser. Your file is not uploaded anywhere.
That runs in your browser tab, so the media never leaves your machine. You can bring the lighter file into the project as ordinary media, or go through Adobe's Attach Proxies path, which matches proxy files to full-resolution ones using, in Adobe's words, "a combination of criteria to match files, which include file names, file extensions, tape names, and timecode" — worth knowing before you rename anything. If you want the knobs rather than a preset, how to compress a video without losing quality covers what actually moves the needle.
How to tell it worked
When Create Proxies runs successfully, two things are documented to happen.
First, the dialog: "In the Create Proxies dialog, use the default frame size of Half and set the preset to the default ProRes QuickTime Proxy, or choose any other frame size and preset." If that dialog opened, the eligibility check passed.
Second, the files on disk. Adobe describes the default naming and location precisely: Premiere appends _Proxy to the name of your proxy clips — scene01_Proxy.mxf is Adobe's own example — and places them in a folder named Proxies "that is placed right next to the full resolution clips." If that folder appeared beside your footage, the job ran.
The encoding itself happens in Adobe Media Encoder, not in Premiere, so that is where you watch progress and where failures will surface.
The other route: set it at ingest
You do not have to proxy after the fact. Premiere's ingest settings include proxy creation as one of four documented modes:
- Copy — "You can copy the media as it is to a new location."
- Transcode — transcode files to a different format on import.
- Create Proxies — "Use this option to create and attach proxies to the media."
- Copy and Create Proxies — "This option copies media and creates proxies for them as well."
Same eligibility rules apply, but handling it at ingest means the work happens once, up front, instead of mid-edit.
FAQ
Why is Create Proxies greyed out in Premiere Pro? Because the selected item fails one of the four conditions Adobe lists: it has captions, it is not a video file, it is a growing file, or its media is offline. Adobe's create-proxies page gives those four and nothing further — no mention of drive location, resolution, or codec.
Do captions really block proxy creation? Yes. Adobe's wording is "You can create proxies only for video clips without captions," and the restatement adds "have no captions" as an explicit requirement for master clip project items.
Can I create proxies for audio files or image sequences? No. Adobe's attach-proxies page names audio-only files, stills, and image sequences as unsupported file types for the proxy workflow.
Will proxies make my export faster? Not by default. Adobe states that "By default, Premiere uses full resolution media while exporting, even if you have enabled proxies," and that using them on export requires selecting Use Proxies in the export settings — a checkbox Adobe says "will default to unchecked." So a slow export is a separate problem from a slow timeline; see Premiere Pro's error compiling movie message and the rest of the fix guides.
What else does the proxy workflow not support? Adobe lists four limitations on its ingest and proxy overview: it is not compatible with After Effects proxies, Dynamic Link is not supported for After Effects compositions or projects, editing audio in Adobe Audition is not supported for proxy workflows, and the option to modify audio channels and interpret footage is not supported.
