If Premiere Pro just refused to import your footage with an “unsupported compression type” error, your project isn’t broken — your file just needs a codec or format fix. This error has a handful of well-known causes, and most of them have fast solutions. This guide walks you through each fix in order of effectiveness, starting with the most reliable method.
What Does “Unsupported Compression Type” Mean in Premiere Pro?
When Premiere Pro throws this error, it means the application cannot decode the video (or audio) file you’re trying to use. Premiere Pro supports a wide range of formats, but it relies on specific codecs to read and play media. If the file uses a codec that Premiere doesn’t recognize or doesn’t have access to on your system, it simply refuses to open it.
This error can appear at different points in your workflow. You might see it when dragging a file into the Project panel, when a clip appears in the timeline but won’t play, or occasionally when trying to export. The clip itself is usually fine — the problem is a compatibility gap between your file’s encoding and what Premiere can handle.
The good news is that this error is almost always fixable without losing footage quality.
Common Causes of This Error
Before jumping to fixes, it helps to know what’s likely causing the problem. Here are the most frequent culprits:
-
HEVC / H.265 footage from iPhones, DJI drones, or modern Android phones, which requires a codec extension on Windows that isn’t installed by default.
-
MOV files using unsupported codecs such as older Apple MPEG-4 variants or certain GoPro codec versions that Premiere doesn’t natively support.
-
MKV or AVI files with non-standard compression like DivX or Xvid, which Premiere has never supported natively.
-
MXF files from broadcast cameras using proprietary or manufacturer-specific compression schemes.
-
Corrupted or partially downloaded media files that are technically unreadable by any application.
-
An outdated version of Premiere Pro that predates codec support added in more recent updates.
Fix 1 — Transcode the File to a Compatible Format (Recommended)
Transcoding means re-encoding your file into a format Premiere Pro can always read. It’s the most universally reliable fix regardless of what codec is causing the problem. H.264 inside an MP4 container is the safest target — Premiere handles it natively on both Windows and Mac.
Use HandBrake (free) to transcode your file:
-
Download and install HandBrake from handbrake.fr. It’s free and available on Windows, Mac, and Linux.

-
Open HandBrake and click Open Source, then select your problematic video file.
-
Under Output Settings, set the container to MP4.

-
In the Video tab, set the codec to H.264 (x264) and choose the Fast 1080p30 preset as a starting point (or match your source resolution and frame rate manually).
-
Set a destination file path using the Browse button at the bottom.

-
Click Start Encode and wait for the process to finish.

-
Re-import the newly encoded file into Premiere Pro.

The re-encoded file should import without errors. HandBrake at high quality settings produces minimal visible quality difference from the source.
Note: If you’re comfortable with the command line, FFmpeg is a fast alternative. Run ffmpeg -i input.mkv -c:v libx264 -crf 18 output.mp4 to convert almost any file to a Premiere-friendly H.264 MP4. The -crf 18 value keeps quality high.
Fix 2 — Use Adobe Media Encoder to Convert the File
If you have a Creative Cloud subscription, Adobe Media Encoder is already installed alongside Premiere Pro. It handles many formats HandBrake supports and keeps you inside the Adobe ecosystem, which can be helpful for maintaining project organization.
-
Open Adobe Media Encoder from your Creative Cloud desktop app or from within Premiere via File → Export → Media (then send to queue).

-
To convert a standalone file directly, open Media Encoder and drag your problematic clip into the Queue panel.

-
Click the blue format/preset link next to the file in the queue. Set the Format to H.264 and the Preset to Match Source - High Bitrate.

-
Set your output destination using the file path link.

-
Click the green Start Queue button (or press Return) to begin encoding.

-
Once complete, import the output file into your Premiere Pro project.

Media Encoder is particularly useful when you have multiple problematic files, since you can batch-add them all to the queue and encode them at once.
Fix 3 — Install the Missing Codec (Windows: HEVC)
If your footage comes from an iPhone, DJI drone, or GoPro Hero (recent models), there’s a good chance it was recorded in HEVC (H.265). This is the single most common cause of the “unsupported compression type” error on Windows, because Windows does not include HEVC decoding by default.
-
Open the Microsoft Store on your Windows PC.
-
Search for “HEVC Video Extensions” or use this direct link: ms-windows-store://pdp/?productid=9NMZLZ57R3T7 (paste into your browser’s address bar or Run dialog).

-
The extension is officially listed at $0.99, but searching for “HEVC Video Extensions from Device Manufacturer” often surfaces a free version distributed by hardware partners. Install whichever is available to you.

-
Restart Premiere Pro and try importing the file again.

After installing the HEVC extension, Premiere Pro can often read H.265 files directly without any transcoding.
Note for Mac users: macOS supports HEVC natively, so this fix applies to Windows only. If you’re on a Mac and still getting this error with HEVC footage, update Premiere Pro or transcode the file.
Fix 4 — Update Adobe Premiere Pro
Premiere Pro adds codec and format support with nearly every major update. If you’re running a version that’s more than a few releases behind, an update alone may resolve the error.
Check for updates via Help → Updates inside Premiere Pro, or open the Creative Cloud desktop app, find Premiere Pro in your apps list, and click Update if one is available.

Fix 5 — Identify and Isolate the Corrupted File
If none of the fixes above work, the file itself may be damaged. Download VLC Media Player (free at videolan.org) and try opening the file there. VLC supports almost every codec in existence — if it also fails to play the file, the file is corrupted, not just incompatible.
In that case, re-download the file from its original source, re-export it from whatever application created it, or recover the original footage from your camera’s memory card if it’s still available.

FAQ
Why does Premiere Pro say “unsupported compression type” for a .mov file?
MOV is a container format, not a codec. It can hold many different types of compressed video. If the MOV file uses a codec Premiere doesn’t support — such as an older Apple MPEG-4 variant or a specific GoPro codec — you’ll hit this error. Transcoding the MOV to H.264 MP4 in HandBrake or Media Encoder resolves it every time.
Can I fix this without converting the file?
Sometimes, yes. Installing the HEVC codec extension on Windows or updating Premiere Pro can eliminate the error without transcoding. However, those fixes only apply to specific causes. If the file uses a genuinely unsupported codec, transcoding is the only option. It’s worth trying the quick fixes first before encoding.
Does this error affect audio files too?
Yes, though it’s less common. Audio encoded in certain formats, such as FLAC inside specific containers or uncommon PCM variants, can trigger this error. Transcoding the audio to AAC or PCM WAV using Audacity or HandBrake resolves it in the same way it does for video files.
Will transcoding reduce my video quality?
Transcoding to H.264 at a high bitrate introduces minimal visible quality loss for most editing purposes. If you want a genuinely lossless editing intermediate, transcode to Apple ProRes on Mac or DNxHD on Windows or Mac. Both are editing-optimized codecs that preserve full quality and keep Premiere’s performance smooth.
This happens with footage from my DJI drone — why?
DJI cameras record in HEVC (H.265) by default. On Windows, the fix is to install the HEVC Video Extensions from the Microsoft Store. To avoid the issue entirely on future shoots, go into your DJI camera’s video settings and switch the recording codec from H.265 to H.264. The file sizes will be slightly larger, but imports will be seamless.
Next Steps
Start with the fastest check for your situation: if you’re on Windows with HEVC footage, install the HEVC codec extension first. If your Premiere Pro version is outdated, update it. If neither applies or works, transcode to H.264 using HandBrake or Adobe Media Encoder — it takes a few minutes and permanently solves the problem without meaningful quality loss. Once your file imports cleanly, you’re back to editing.
