Hopefully, you can import the files without seeing the error “The File Has an Unsupported Compression Type.”

• If you are opening a project containing clips, give Premiere time to generate new media cache files.

It’s also possible you are trying to import an unsupported format, which we’ll discuss next:

2. The File Format is Not Supported

If you are trying to import a file format that Premiere Pro does not support, that’s likely what’s triggering the error.

If that’s the case, you’ll need to transcode the file to a supported format (pretty easy!). I’ll show you that next.

• If you are using OBS studio to record your videos, skip to this part.

Check out this list of supported file formats in Premiere Pro.

• Make sure that both the codec and format are included in the list from Adobe.

2.1 Transcode

To transcode your file, I recommend downloading Shutter Encoder (opens in a new tab); this is one of the best free transcoders.

1. Drag and drop your video on the white space area inside Shutter Encoder to import.
   • Alternatively, click on Browse, and navigate to the clips in your file system.
2. Under Choose function, pick a lossless codec.
   • I often use DNxHD for 1080p, and DNxHR for 4K.
3. Click on Start function to transcode.
   • By default, the files will be located at the exact location as the original clips.

Now, import the transcoded clips to Premiere Pro.

2.2 Remux Recordings in OBS Studio.

MKV files are the default recording format in OBS studio; however, MKV is not supported by Premiere Pro as v.13.1.3.

Luckily, the developers of OBS studio are aware of this and have created a solution.

1. Inside OBS studio, click on File > Remux Recordings.

2. Select the clips you cannot import to Premiere Pro, and click on Remux.

Now you’ll create an MP4 version of all the MKV files.

3. Change the File Location

Sometimes Premiere Pro has problems connecting to clips on your storage device due to a restricted area, weird file path, etc.

A quick way to fix this is by changing the location of the clips.

If you are multiple storage units, try changing to another one.

4. Change File Name Extension

Another fix that seems to work for many people facing the error “The File Has an Unsupported Compression Type” is changing the file name extension.

1. Open the folder containing your clips.
2. Windows: Click on View > Show > File name extensions.
   • macOS: Check out this quick guide from apple.

3. Right-click the file > Show more options > Rename.
4. Change the file name extension to .MTS or .MP4

Doing this can be a bit time-consuming if you have a lot of clips; in that case, check out the YouTube video below:

5. Rename Files

Many users have reported that renaming their files using only standard letters from the English alphabet has fixed the error.

Ensure that your files do not contain any symbols or uncommon letters.

6. Trial Version of Premiere Pro Does Not Support the Format

Users have reported the trial version of Premiere Pro might trigger the error; if you are trying to import MP4 or AVCHD files, they require the paid version of Premiere Pro (source).

7. Trim the Clip

It’s also been reported trimming a second off the clips you are trying to import solved the issue.

To do this, you must import your clips to another editing software…

I’ve found using the pre-installed Movies & TV to be a quick alternative on Windows.

Right-click the clip > Open with > Movies & TV. Then, inside the software, trim the beginning of your clip by a second.

• Once you’ve trimmed the clip(s), try importing it to Premiere Pro.

8. Re-Install Premiere Pro

If none of the above solutions fixed the error, a quick re-installation of Premiere Pro might be your best bet. Doing this should get rid of any bugs in the software that might be causing problems.
