In Premiere version 25.2 and later, the "Mercury Playback Engine Software Only" option has been removed from Project Settings — it is not hidden behind a driver problem or a preference, it is gone. Adobe says so on a dedicated page, in one sentence:
"In Premiere (version 25.2 and later), the option to choose software rendering (“Mercury Playback Engine Software Only”) from Project Settings > General has been removed."
That single change is why thousands of troubleshooting articles — and one of Adobe's own pages — now tell you to select something you cannot find. Below is exactly what was removed, what was not removed, and which machines were affected.
What changed, at a glance
Every row here is quoted or paraphrased from Adobe's software rendering removal page.
| Question | What Adobe's page says |
|---|---|
| Which versions | "version 25.2 and later" |
| Where the option used to be | Project Settings > General |
| What was removed | The choice of software rendering |
| Platforms listed as affected | Premiere – Windows; Premiere - Macintosh Intel; Adobe Media Encoder - All platforms |
| Apple silicon | "This change has no effect on Premiere on Apple silicon computers, as software rendering has never been an option on this platform." |
| Does it affect exporting? | "This change only affects rendering. Customers can still choose to use software encoding when exporting." |
| Why is Renderer greyed out? | Only one GPU type is present, so there is no second type to pick |
Why Adobe removed it
The stated reason is quality and performance, not licensing or GPU support:
"Software rendering can cause poor performance and rendering in 8-bit, which can result in image quality issues."
The 8-bit part is the interesting half. Software rendering was not simply a slower path to the same picture — Adobe describes it as rendering at a lower bit depth, with image quality consequences. That reframes the old advice: for years "switch the renderer to Software Only" was passed around as a harmless compatibility toggle, and Adobe's own note on the troubleshooting page already warned that "Enabling the Mercury Playback Engine Software Only option may slow down the rendering speed."
The advice you found is probably still quoting the old page
This is the part that makes the option feel "missing" rather than removed. Two current Adobe pages disagree:
- The troubleshooting page for render and export issues (self-dated Mar 5, 2026) still lists it as a step: "If you are not exporting to H.264, or if the issue persists, select File > Project Settings > General, and in the Video Rendering and Playback section, select Mercury Playback Engine Software Only."
- The software rendering removal page (self-dated Apr 2, 2026) says the option "has been removed."
We are not going to adjudicate which page Adobe intends you to follow. The practical reading is simpler: if you are on 25.2 or later and the step tells you to pick Software Only, that step does not apply to your build, and you should move on to the next one rather than hunt for a menu entry. The same logic applies to third-party articles on error compiling movie in Premiere Pro, where this toggle is very often listed as fix number one or two.
What the Renderer dropdown does now
Here is the sentence that resolves the most common follow-up question — "my Renderer menu is greyed out, is my GPU broken?":
"On a computer with a single type of GPU, that GPU will be selected in Project Settings > General > Renderer, and the menu will be greyed out, as there is no second GPU type to select. The playback engine shown is active and being used for rendering."
Read the last clause carefully. Greyed out means "nothing else to choose", not "not working". The engine named in that greyed-out field is the one doing the work.
If your machine has two GPU types, you do get a choice: "On a computer with two GPU types, you may select which GPU type, either OpenCL or CUDA, is being used for rendering."
And if the GPU option itself is absent, Adobe's page on enabling the GPU renderer gives the path — File > Project Settings > General > Video Rendering and Playback section, then "Select Mercury Playback Engine GPU Acceleration (OpenCL) from the Renderer dropdown" — plus one remedy: "If you can't find the Mercury Playback Engine GPU Acceleration option after updating or reinstalling Premiere, try doing a clean install of your GPU drivers, NVIDIA and AMD®."

If you only came here because an export needs to be smaller and the renderer was a red herring, the compressor above re-encodes in your browser tab — nothing is uploaded, and it does not need Premiere open. Full list at all Clapr tools, or start with the video compressor.
Rendering and encoding are two different menus
The single biggest misreading of this change is "Adobe killed software encoding." It did not. Adobe's wording is explicit that only rendering changed, and that "Customers can still choose to use software encoding when exporting. For best performance, the use of hardware encoding is strongly recommended."
That export-side control lives in the Performance dropdown in the export settings, and it is worth knowing that Adobe's pages use two different names for both of its values. The encoding settings reference calls the default "Hardware Encoding"; the export settings reference calls it "Hardware Accelerated". The fallback is called "Software Encoding" on the Premiere page and "Software Only" on the Media Encoder page. Same dropdown, four names across the documentation — which is why searching for the exact string you saw in an article often turns up nothing.
That fallback is also automatic: "If your system does not support certain export settings, the Performance menu switches automatically to Software Encoding." So Performance flipping itself to software is documented behaviour tied to the export settings you chose, not evidence that your hardware failed.
Platform gotchas worth knowing
- Apple silicon users never lost anything. Quoted above, verbatim: software rendering "has never been an option on this platform." If a tutorial shows the menu on an M-series Mac, the screenshot is from an Intel machine.
- The affected list names Adobe Media Encoder - All platforms, while the Apple silicon exemption sentence is written about Premiere. The two statements have different scopes, so read the list as Adobe wrote it rather than merging them.
- The old troubleshooting note is still worth remembering for older builds: "Software Only mode isn't available on Apple computers that use Apple Silicon processors."
- Regression path. Adobe gives an explicit instruction for projects that used to work: "If you have a project that rendered correctly using software rendering in version 25.1 or earlier that no longer renders correctly in later versions, please submit a bug report so we can fix the issue." That is a supported route, not a brush-off — use it instead of downgrading blindly.
FAQ
Where did Mercury Playback Engine Software Only go in Premiere Pro? It was removed from Project Settings > General in version 25.2 and later. Adobe lists the change as affecting Premiere on Windows, Premiere on Macintosh Intel, and Adobe Media Encoder on all platforms.
My Renderer dropdown is greyed out. Is my GPU not supported? Not according to Adobe's explanation. On a computer with a single type of GPU, that GPU is selected and the menu is greyed out because there is no second GPU type to select — and the playback engine shown "is active and being used for rendering."
Can I still export using software encoding? Yes. Adobe states the change "only affects rendering" and that software encoding remains selectable when exporting, while recommending hardware encoding for best performance.
Why does an Adobe page still tell me to select Software Only? Because two Adobe pages currently say different things: the render and export troubleshooting page still lists the step, while the newer software rendering removal page says the option was removed in 25.2 and later.
My project rendered fine before the update. What should I do? Adobe asks you to file a bug report for projects that rendered correctly with software rendering in 25.1 or earlier and no longer render correctly in later versions.
Where can I read more limits like this one? See the rest of the limits and specs articles for other version-gated behaviour in editing software.
