Workarounds to File Format Not Supported by Premiere Pro CC

Adobe Premiere Pro supports several audio and video formats, making your post-production workflows compatible with the latest broadcast formats. But something may let you down, when you drag video files to Adobe Premiere Pro CC, CS6, the “file format not supported” message occurred from time to time.

Why can’t Premiere Pro import my file?

If you’re trying to import a file into Premiere Pro, and Premiere Pro is telling you that it can’t import that file, this could be for a few different reasons. And there are three most common reasons that you might not be able to import a file into Premiere Pro.

  1. You might be running the trial version of Premiere Pro CS6 or earlier. So try to upgrade your Premiere Pro. Adobe only allows licensed Creative Cloud members to access to some codec, such as HEVC. So your problem might be solved simply by stopping using the trail version and purchasing a code. There is no problem to import a Samsung HEVC clip, but when it comes to GoPro Hero7 HEVC video, it crashes. Upgrade your Premiere Pro, maybe from 2019 to 2020, to have a try.

2. You might be trying to import a file of a format that Premiere Pro doesn’t import, so check the file for format supported for import, to see if your file is listed.

What File Format does Premiere Pro Accept?

Adobe Premiere Pro natively supports many types of files including video formats like Apple ProRes, ASF, AVI, DNxHD, DNxHR, H.264 AVC, HEVC, MP4, MOV, and audio formats including AAC, MP3 and more. Go to Adobe Premiere Pro Supported File Format to see full lists.

a. What audio format is supported by Adobe Premiere Pro?

It supports 3GP, 3G2 (.3gp), AAC, AIFF, AIF, ASND, OMF, BWF, M4A, MP3, and WAV audio format.

b. What types of video formats does Premiere Support?

Adobe Premiere Pro supports popular multi-media format including AVI (Windows AVI and DV AVI), MXF, MP4, VOB, Windows Media (ASF, WMV), and DV, as well as the majority of MPEG-based formats, as like H.264 AVC, HEVC, M4V, M2V, MTS, M1V and M2T(S).

Apple ProRes, ProRes HDR, Panasonic AVI-Intra, DNxHD/DNxHR by Avid (capsulated in MXF/AVI), Rush, CRM, OpenEXR, R3D are also supported by Premiere Pro.

c. What types of images/subtitles/text supported by Premiere Pro?

Premiere Pro supported still images (sequences): AI, EPS. BMP, DIB, RLE, DPX, EPS, GIF, ICO, JPEG, PNG, PSD, PTL, PRTL, TGA, ICB, VDA, VST, TIFF. As for text, captions and subtitles, it supports DFXP, MCC, SCC, SRT, STL, and XML.

3. If you’re trying to import a file, in a container that Premiere Pro does support, it may be that codec used in that container file, is not one that Premiere Pro can import.

Remember that whether your video can be imported or not depends on video codec format, not video container format. Yes, they are not the same thing. For examples:

1.) MKV seems to be not supported, but can be imported sometimes

MKV is not on the official supported file format list, but actually it has been natively supported in Premiere Pro 2018 12.1 and later, although there still are loading errors. Our test shows that some MKV videos can be loaded, while some others cannot. The reason might be that MKV is a container format, but video codec format is the linchpin in decoding.

2.) Premiere Pro supports MP4, but not all MP4 can be imported

MP4, a container format, is natively supported for import by Premiere Pro. But it comes with the details “QuickTime Movie, XDCAM EX”. An educated guess is if your video is not QuickTime (MPEG-4 Part 12) but the extended part MPEG-4 Part 14 (.mj2, .dvb. .dcf. .m21, .f4v), or the video is recorded by XDCAM SD, XDCAM HD/HD 422, it might not be loaded correctly even if it is MP4.
