When Premiere's Performance dropdown shows Software Encoding and will not let you change it back, Adobe's own documentation points at your export settings first, not at your graphics card. The video encoding settings reference says it in one sentence: "If your system does not support certain export settings, the Performance menu switches automatically to Software Encoding."
That is the single most useful line on this topic, and it reframes the problem. You are not looking for a broken GPU. You are looking for which setting in the current export you just configured is outside what Adobe documents as hardware-encodable.
What the Performance menu actually controls
Three things from Adobe's encoding settings reference are worth reading closely:
- "(H.264 and HEVC only) – Hardware Encoding is the default choice, which tells Premiere to use available hardware on your system to speed up encoding times."
- "Hardware acceleration depends on your system's configuration."
- "If your system does not support certain export settings, the Performance menu switches automatically to Software Encoding."
The first line carries a limit that gets dropped in most write-ups: the option is documented as applying to H.264 and HEVC only. If your export format is ProRes, DNxHD or anything else, there is no hardware encoding choice to lose in the first place.
The third line describes an automatic switch, not a failure. Premiere is reacting to the combination of settings currently in the dialog. Change the combination and the menu can come back.
The fastest fix: match the settings Adobe documents
Adobe's page on enabling hardware encoding gives four instructions, verbatim:
- "Set the Format option to H.264."
- "Set the Performance option to Hardware Encoding."
- "Encode your videos using H.264/AVC (8-bit) or HEVC 4:2:0 (8-bit and 10-bit). If you're running a 10th-generation or newer Intel® Core™ processor, you can increase the HEVC resolution to 8192x8192, otherwise, limit it to 4096x4096."
- "Use Intel® Core™ processors from the 9th to the 12th generation for HEVC 4:2:0 10-bit hardware encoding."
Work down that list against your actual export. A 6K HEVC export on a CPU older than 10th-generation Intel is above the 4096x4096 ceiling Adobe states for that case. A 10-bit setting is fine for HEVC 4:2:0 on that list, but the H.264 entry is written as 8-bit — so if you raised Profile to High 10 (which the encoding settings page documents as the requirement for certain Export Color Space choices in H.264), you are no longer on the setting that page lists.
Adobe also documents one specific combination that goes to software even on hardware that otherwise qualifies: "Apple silicon (M1 Pro, M1 Max, M1 Ultra or newer) supports hardware-accelerated encoding and decoding for H.264 and H.265, including 10-bit 4:2:2 decoding. However, HEVC HLG 4:2:0 10-bit encoding still relies on software."
That is the shape of this whole problem. One checkbox deep in the export dialog, and the Performance menu quietly moves.
Try it right here
Runs in your browser. Your file is not uploaded anywhere.
If the reason you wanted hardware encoding was simply a faster path to a smaller file, the compressor above re-encodes in your browser tab without touching Premiere's export dialog at all. Nothing is uploaded — the file is read from disk, re-encoded locally and handed back. For the settings side of that trade, see how to compress a video without losing quality.
Why every answer you find contradicts the last one
This is the part nobody in the forum threads has noticed. Two Adobe pages, both showing an update date of Jan 7, 2026, give different hardware requirements for the same feature.
- The H.264/H.265 playback optimisation page: "For hardware-accelerated decoding or encoding to work, an Intel® CPU with Intel® Quick Sync support is required."
- The hardware-accelerated encoding and decoding page: "To take advantage of these features, your system needs a GPU that supports hardware acceleration. The support varies depending on the GPU's manufacturer: NVIDIA, Intel, AMD, or Apple silicon."
One says Intel Quick Sync is required. The other lists NVIDIA, Intel, AMD and Apple silicon. A third page, the Windows system requirements, lists "Intel® 11th Gen or newer CPU with Quick Sync – or AMD Ryzen™ 3000 Series / Threadripper 3000 series or newer CPU".
We are not going to adjudicate which page is right, and you should be suspicious of any article that does. The practical rule: treat the Performance menu on your own machine as the answer. If it offers Hardware Encoding for an H.264 export with plain 8-bit settings, your system qualifies regardless of which page you read.
The names change from page to page
Part of why this is hard to search is that Adobe's pages do not use one name for anything here.
| Thing | Names used across Adobe's pages |
|---|---|
| The default Performance item | "Hardware Accelerated" (export settings reference) / "Hardware Encoding" (encoding settings reference) |
| The fallback item | "Software Encoding" (Premiere page) / "Software Only" (Media Encoder page) |
| The Preferences checkbox | "Enable hardware accelerated decoding (requires restart)" / "H264/HEVC hardware accelerated decoding (requires restart)" |
Note what that last row is about: decoding, not encoding. It is a different control from the Performance dropdown, and Adobe's export troubleshooting page uses it in the opposite direction — "Go to Preferences > Media and deselect Enable hardware accelerated decoding (requires restart) to export to H.264 or HEVC." Turning that checkbox off is a documented troubleshooting step for exports that hang; it is not how you re-enable hardware encoding.
A different greyed-out menu that gets confused with this one
If the greyed-out control you are looking at is the Renderer dropdown in Project Settings, that is a separate story with its own official explanation: "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."
Greyed out there means there is nothing to choose between, not that acceleration is off. Adobe also removed the software rendering option entirely: "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." Crucially, the same page limits the scope — "This change only affects rendering. Customers can still choose to use software encoding when exporting."
That distinction matters if you arrived here from an article about export failures, since most of them still recommend a setting that no longer exists. Our write-up on Premiere Pro "Error compiling movie" covers that overlap.
When to switch hardware encoding off on purpose
Adobe's Media Encoder known issues page documents cases where hardware encoding is the cause rather than the cure:
- "Hardware Encoding on Windows systems with GeForce GTX 1630, GeForce GTX 1650, or GeForce GTX 1650 Ti NVIDIA GPUs with driver version 551.61 may have corrupt frames." The stated workaround: "Update to NVIDIA Studio driver 551.86 or later to fix the issue."
- "Hardware-encoded HEVC files generated on an Apple Silicon cannot playback or seek." The stated workaround: "Disable hardware encoding HEVC outputting."
If your exports complete but look wrong, check those two before assuming the encoder choice was the problem.
How to tell it worked
Set Format to H.264 with 8-bit settings, then watch the Performance menu as you change the rest of the dialog. If it stays on Hardware Encoding after you pick your preset, frame size and profile, hardware encoding is engaged for that export. If it flips the moment you touch a particular control, you have found the unsupported setting.
FAQ
Why is Hardware Encoding greyed out in Premiere Pro? Adobe's documented cause is that the current export settings are not supported, in which case "the Performance menu switches automatically to Software Encoding." The option is also documented as applying to H.264 and HEVC only, so other formats never offer it.
Does hardware encoding require an Intel CPU with Quick Sync? Adobe's pages disagree. One states an Intel CPU with Quick Sync support is required; another lists NVIDIA, Intel, AMD and Apple silicon as supported manufacturers. Go by what your own Performance menu offers, and check the official documentation for the current wording.
Is Hardware Encoding or Software Encoding better quality? Adobe does not rank them on quality in these pages. What it does say, in the context of removing software rendering, is "For best performance, the use of hardware encoding is strongly recommended."
Will enabling hardware accelerated decoding in Preferences fix the greyed-out Performance menu? That checkbox controls decoding, which is a separate feature. Adobe's export troubleshooting page actually tells you to deselect it when exports hang on H.264 or HEVC.
Can I just compress the file after exporting instead? Yes, and for delivery-size problems that is often quicker than fighting the export dialog. Export once at settings that work, then shrink the result — see all Clapr tools or the compressor directly.
