Premiere Pro's caption export menus offer SRT, SCC, MCC, XML and STL — not VTT. Adobe publishes four separate caption format lists for Premiere, and WebVTT does not appear on any of the four.
Worth being precise about what that means: none of those pages states that WebVTT is unsupported. VTT is simply not among the formats they enumerate. The practical consequence is the same — there is no .vtt entry in the dropdown — but it also means the interesting story here is not the missing format. It is that the four official lists do not agree with each other.
The four caption lists, side by side
| Official Adobe page | Caption formats it lists | Count |
|---|---|---|
| Export settings reference in Premiere | .scc / .mcc / .xml / .stl / .srt | 5 |
| Supported caption file formats in Premiere | SCC / MCC / XML / STL / SRT / DFXMP | 6 |
| Supported file formats in Premiere (import) | DFXP / MCC / SCC / SRT / STL / XML | 6 |
| Export captions in Premiere Pro (Text panel route) | plain text / CSV / SRT | 3 |
| VTT or WebVTT | not listed on any of the four | 0 |
Every cell above is a verbatim reading of an Adobe help page. The row that matters for most readers is the last one, but the rows above it explain why answers to "which subtitle formats does Premiere support" vary so wildly depending on which page someone happened to read.
Where the four lists disagree
Three different spellings of the same family. The supported caption formats page lists DFXMP as a sidecar format. The import format table lists DFXP, glossed as "Distribution Format Exchange Profile". The export settings reference lists neither — although its XML entry is described on the caption formats page as covering "W3C TTML (also known as DFXP)", plus SMPTE-TT and EBU-TT. Three pages, two spellings, and a third page where the abbreviation does not appear at all.
Two export routes with different menus. Premiere has two documented ways to get captions out, and they hand you different options:
- The export settings Captions section. Its sidecar dropdown is documented as "Scenarist Closed Caption File (.scc)", "MacCaption VANC File (.mcc)", "W3C/SMPTE/EBU Timed Text File (.xml)", "EBU N19 Subtitle File (.stl)" and "SubRip Subtitle Format (.srt)".
- The Text panel. Adobe's route is
Captions tab > Ellipsis menu icon, then "Select Captions and the desired file format:" — and the three choices given are "Export to text file: Plain text file", "Export to CSV file: Comma-separated values file" and "Export to SRT file: SubRip subtitle file for adding captions to videos".
Same application, same captions, two menus, one overlapping format. If a tutorial tells you Premiere exports five caption formats and your Text panel shows three, neither of you is wrong — you are looking at different doors.
The embed list is short, and MP4 is not on it. The export settings reference notes: "Embedded captions are only available for certain formats such as QuickTime and MXF OP1a." The caption formats page gives its own list under "Premiere also supports embedding into and decoding from the following file formats:" — MOV, DNxHD MXF Op1a, MXF Op1a. So "just embed the captions in my MP4 instead" is not a documented path either.
SRT is the one format on all four lists
That makes it the sane pivot. It is also the format Adobe documents most thoroughly, and the details are worth knowing before you export.
On how many tracks you get per file, Adobe is specific: "While the .srt extension only supports one stream per file, it can support multiple formats, such as 608, 708, Teletext, EBU, Australian, and Subtitle." Compare that with the alternatives — .scc "only supports 608 tracks", .xml "only lets you choose one track from all the different formats supported by .xml", and .stl "supports one stream at a time". Only .mcc is documented as letting you "export 608 and 708 tracks all at once".
Which track lands in the file is decided for you unless you intervene: "The track that is active in the timeline is automatically selected as a default. If there are two or more tracks enabled, the one with the lowest number of tracks is selected." For a multilingual sequence, that is the difference between shipping the right language and shipping whichever track happened to be selected.
One more line explains why your dropdown may be shorter than the documented five: "The active subtitle track type determines what formats are available in the menu."
What to do when you need WebVTT
Export SRT from Premiere, then convert it. That is the whole workflow, and it is not a workaround so much as the normal division of labour — SRT is what editors hand over, WebVTT is what web players consume.
Try it right here
Runs in your browser. Your file is not uploaded anywhere.
This runs in your browser tab. The file is read from disk, converted locally and handed back, so a client's script never touches a server. If you need the reverse direction later — a web caption file that has to go back into an editor — VTT to SRT is the same conversion the other way, and SRT vs VTT compared covers what actually differs between the two.
Going back into Premiere is documented and painless: "Import the SRT file into your Premiere project just like any piece of media", then "Drag the SRT from the Project panel into your sequence and drop it anywhere in the sequence." Adobe adds that "Premiere creates a new caption track, and the captions are placed on the track."
Premiere-specific gotchas
The Captions section can be greyed out entirely. Adobe states it plainly: "The Captions section is disabled if the source sequence does not contain any caption tracks." If there is no dropdown to look at, the sequence has no caption track yet — that is the problem to fix first, not the format.
Four caption modes, and only one produces a file. The export settings offer "None: Premiere will not include captions", "Create Sidecar File: caption information will be exported as a separate text file alongside the video file", "Burn Captions Into Video" — where the text is "graphically 'burned in' to the video and cannot be disabled on playback" — and "Embed In Output File", where captions become "a separate stream" that "can be disabled or enabled when playing back the video on supported devices". Only Create Sidecar File gives you something to convert.
Do captions late. Adobe's own recommendation: "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."
FAQ
Can Premiere Pro export VTT or WebVTT? Not through any documented menu. VTT does not appear on Adobe's export settings caption list, the supported caption formats page, the import format table, or the Text panel export list. Export SRT and convert it with SRT to VTT.
Why does my Premiere caption dropdown show fewer formats than the docs? Because of this documented rule: "The active subtitle track type determines what formats are available in the menu." The list is filtered by what kind of caption track is active in your sequence.
Is DFXP or DFXMP the right spelling? Both appear in Adobe's documentation — DFXMP on the supported caption formats page, DFXP on the import format table. The caption formats page also describes the XML export as "W3C TTML (also known as DFXP)". If you need certainty for a delivery spec, check the official documentation for the version you are running.
Can I embed captions into an MP4 from Premiere instead? The documented embedding targets are QuickTime and MXF OP1a on one page, and MOV, DNxHD MXF Op1a and MXF Op1a on another. MP4 is on neither list, so treat sidecar export plus conversion as the reliable route.
Can one SRT file hold several caption tracks? No — Adobe states that "the .srt extension only supports one stream per file", though it can carry several caption formats. Export one file per language and convert each.
