[Fixed] DaVinci Resolve Media Offline/H265 Missing Issue

From DaVinci Resolve's official webpage, we can know that DaVinci Resolve has already expanded its format compatibility to most modern video formats like MP4, AVI, QuickTime MOV, AVC, MXF, DCP, etc. The commonly seen video codecs like H264, HEVC (x265) are also covered.

Yet, theory is one thing, practice is another. During the actual operation, you would be greeted by "Media Offline" error message when you import your HEVC to DaVinci Resolve 18/17 or older 16/15 version. If this happens to you and you still don't find the way to troubleshoot this issue, stay here and follow the below top solutions to tackle this media offline frames/flashing issue in DaVinci Resolve.

Can't Import HEVC to DaVinci Resolve? Convert HEVC to H264 for Smooth Loading

The most foolproof solution is to convert HEVC to H264 or MPEG-4 codec for smooth video importing. Thus, you just need a solid HEVC video converter - Winxvideo AI to convert HEVC to H264 or MPEG-4 codec with 98% quality kept, virtually zero quality degradation. Meanwhile, it can easily change your video frame rate from VFR to CFR if the "media offline" issue is caused by VFR.

Part 1. Upgrade Free Resolve to Studio Resolve

One user seeked for help on forum.blackmagicdesign. He was running DaVinci Resolve 16 Free version on a Windows 10 computer and encountered "Media Offline frame 304: Cannot find the codec for decoding" error when he imported his GoPro Hero 8 Black HEVC video to Resolve. He has already tried everything he could think of, including reinstalling Resolve, updating Resolve to the latest version, re-installing HEVC codec extensions on Windows 10, etc. But he was not the lucky dog. His problem didn't get solved by his own.

Well, there is always the silver lining. Providing you have the same issue as the above user, you can upgrade your free resolve to the Studio version of Resolve. Free Resolve 16 for Windows does not support HEVC decoding. So just upgrade free resolve 16 to Studio Resolve 16, or upgrade Free Resolve 16 to Free Resolve 18 if you don't want to subscribe to DaVinci Resolve Studio version.

Part 2. Check Your HEVC File Extension

Some users, if not all, focus on video HEVC codec while they ignore the HEVC video file extension. One user mentioned that he once changed his Canon 10bit HEVC video from MXF to MPG file extension. But he forgot this stuff. He imported this Canon 10bit HEVC to DaVinci Resolve 17 or 16 and always meeted the same issue - media offline. Later, he checked the video extension and then found the problem root.

Check your HEVC file extension if it's not your DaVinci Resolve version to blame. Generally, DaVinci Resolve accepts file extension like MP4, MOV, AVI, AVC, MXF, etc. So make sure if your HEVC video file extension is in the DaVinci Resolve supported file extension list.

Part 3. Install HEVC Extensions

Sometimes DaVinci Resolve shows media offline, but it's not. When you import all the HEVC video clips inside DaVinci Resolve, they turn offline. However, suggesting you drag them into the timeline and click to play, they are still offline but you hear the audio. This issue results from playing back footage in H.265 or HEVC codec.

The root cause lies in the inability to decode HEVC x265 codec. And this always occurs on Windows 10. The most direct yet effective solution is to install HEVC extensions on Windows 10. Here comes the detailed guide on how to install HEVC extensions on Windows 10.

install hevc extensions
  • Go to Microsoft store or type "microsoft hevc video extensions" in Google and click on the relevant result.
  • Click on "Buy" button. ($0.99 payment for official purchase.)
  • Download and install the hevc extension. Afterwards, restart your Windows 10 PC.
  • DaVinci Resolve is supposed to decode your HEVC video footage now and no more media offline error appears in Resolve.

Part 4. Relink Selected Clips

On top of the afore-mentioned cases, unlikned clips issue could incur media offline flashing issue in DaVinci Resolve when your imported H265 clips inside Resolve lose their link with the source footage placed in the hard disk. It usually happens when you unconsciously move your HEVC x265 video footage to a different folder or drive. In such case, you need to re-load your source HEVC video clips from your folder that contains the source footage.

  • Navigate to Media Pool > select all of your offline clips.
  • Right-click one of the selected clips > opt for "Relink Selected Clips"
  • From the dialog box, locate your folder which covers your desired hevc source footage. Hit Ok.

Part 5. Upgrade Your Resolve and GPU Driver to the Latest Version

If your HEVC video footage has already loaded into Resolve and just some frames display "Media Offline" error during playback, it's highly related with HEVC footages (4K 60 FPS) shot through smartphones like latest iPhone models. In such case, follow the below steps to have your Resolve and GPU driver updated to the latest version:

This generally happens on DaVinci Resolve Studio version, not Free version. Thus, Studio version users try this method:

  • Head to "DaVinci Resolve" -> "Preferences" -> "System" -> "Memory and GPU" -> "GPU Configuration"
  • "GPU Processing Mode" -> Instead of "CUDA" or "OpenCL" > select "Auto".
  • Click "Decode Options" -> uncheck "H.264/H.265 using hardware acceleration".
  • Re-launch your Studio version of Resolve and see if it functions well.

Part 6. Change Variable Frame Rate to Constant Frame Rate

There are several symptoms of Resolve media offline issue. Among them, one symptom - "HEVC video is media offline, but audio seems work fine" or "video plays with out-of-sync audio" shows up at high frequency. The elephant in the room is the Variable Frame Rate (VFR) issue in HEVC footage.

Most game-recording software, OBS and smartphones capture video in VFR while most video editing software like DaVinci Resolve prefers Constant Frame Rate. You users are caught in limbo. But, this is not a encased knot. You can easily get this issue solved by converting variable frame rate to constant frame rate via this user guide.
