Render error

Hello everyone,
I have used DaVinci Resolve for many private video projects. After updating from v18 to v19 (19.1.1 Build 8) DaVinci fails to render some jobs. If the projects contains clips encoded with HEVC, it shows the following error:

Error decoding full resolution media for DJI_0362.MP4
at 00:00:00:00. Please check that the file is accessible
and has a valid codec.

The file exists, is accessible, can be played with other players on my system and can be edited in DaVinci without issues. Only rendering a project containing HEVC encoded clips fails.

The log file shows some more details on the error:

It seems there is a decoding error. I tried changing the render settings to use other output formats and codecs but it doesn't help.

Any suggestions how to fix the issue?

Please indicate Resolve version, operating system, and computer spec (including GPU and driver).

Inclue a link to the complete diagnostic logs.

Meanwhile I installed DaVinci Resolve on another Windows system and tried to render the same file and it just works. So I guess there is an issue with the used Decoder/Encoder on my system. Any suggestions on how to find the culprit?

What GPU and Driver?

Free or Studio Resolve?

I thought the log files contained all the information, but here we go:
- DaVinci Resolve v19.1.1 Build 8, no Studio
- NVIDIA GeForce GTX 980
- NVIDIA GPU Driver: 566.36

Some codecs dort work in the free version.

Meanwhile I installed DaVinci Resolve (free) on another Windows system and tried to render the same video clip and it just works. So I guess there is an issue with the used Decoder/Encoder on my system and the problem is not related to the difference between the free or Studio version.

Could the GTX 980 be too old?
Edit, just checked, should be OK with a compute capability of 5.2.

Can you post a sample with the offending codec?

I narrowed it down a bit by trying different clips. It seems only 10 bit HEVC clips can not be rendered, which definitely worked a couple of weeks ago since I used 10 bit files before.

I created a MediaInfo file containing further video file and codec information. You can download the info file here: https://filetransfer.io/data-package/0UvgnyTD
An example clip (not the one from the info file but same camera): https://filetransfer.io/data-package/53JtQeB4

Yes, that will work only in DR Studio under Windows. It's smooth on a Mac with the free version.
You could transcode the footage to an intermediate codec, but Studio is definitely worth the investment.

I doubt that this is correct.

The test installation was the free version, not Studio and it worked.

W10 or 11?

Hey Tim, I have the same issue with my M1 Macbook Air with Davinci Studio.
Did you manage to solve it on your computer? It's weird the error because sometimes I add some random clips after the file with errors and then the export goes without an issue. But when I only export what I need the same mistake keeps appearing. It also happens when working on different external drives such as SSD and HDD.

Greetings all, I had the same issue on an M2 Max Macbook Pro. I had to remove a video transition, at the time code presented, and the render worked. Not sure why, but the blur transition, in my case, bombed the render in two locations no matter what kind of file I tried to throw at it. I had to remove the blur and just use a fade in/out. I've not had this happen on any other projects and seems to be localized to a single project; thankfully.

I don't like seeing others are dealing with this issue too but at-least I know I'm not alone. Attempted to uninstall & reinstall but no change on my edit. Had some issues on DR18 but they weren't export errors! Bummer but bugs will happen from time to time.

Hopefully this "please check that the file is accessible and has a valid codec" can be patched out! Its funny to know I had to move from my AMD 5955WX/RTX3090 to a base model Mac Min M4 to export a project.

I had the same error. But when I watched that part from my video I noticed that the video was a bit bury. After cutting that part out of the video I was able to render without any problems. Hope this helps.

I had the same issue (on HD rendering) and found that the external SSD SAMSUNG portable T7 Touch was the culprit on my Lenovo Legion 7 Ryzen7, Nvidia GTX 3070, DR Studio 19.1.4 on one of the two USB C Gen 2 ports. When moved to the rear port the problem did not arise. On the suspected port even the Time Line playback hangs continuously. How I found out was, windows chimes a disconnection gong. It is actually a fraction of a second disconnection, I guess as you would not notice anything in device manager. Have not noticed this issue on the other Ext. SSD drives. I usually render videos that are generally two to three hours long. It could be a windows driver issue too. Hope this helps.

I'm editing a wedding video, and boom "Error decoding full resolution media for fx3_0412.MP4 at 01:00:02:21. Please check that the file is accessible and has a valid codec." I don't know what to do. I have a deadline, and I'm screwed. Nothing is working to fix this issue. I should've never downloaded the new version it’s just slowed my computer down and caused problems. I have a new Mac laptop with 1TB of space. If anyone has suggestions, please help. I don’t know what to do.

I'm encountering the exact same issue. Have never experienced this issue. At the said timestamp there are no transitions and the file is found earlier in the rendering process (it is not new).

filmedbyraj - did you find a fix?

no fix

Same issue. something doesn't have a valid codec. Or my favorite, video on the timeline is "media offline" but then all my media in the media pool are connected.

I use a lot of VFX in my videos. They all worked perfectly in Da Vinci Resolve 19. Updated to 20, and now I cannot render anything. And it's random too. Sometimes the VFX is fine and the video renders that part... but fails at a later part. So, I try to render again- and then it fails at the first VFX.

This is ridiculous. I have to render my 45 minute videos in 20 second increments then splice together so I can make my deadlines.

I don't care about your new AI tools. I just want the video editing/ rendering that you had in version 19. Or at the very least, acknowledge there is a bug and give us a timeline on when you expect it to be released.

Until this can be resolved... can you please make Da Vinci Resolve 19 available again?

19 is available on the support page, even far older versions.

All versions of Resolve back to 10.1.5 are available for download in the DaVinci Resolve and Fusion area of the Support page:

Hopefully you followed the guidance on the Resolve 20 Read More area:

For DaVinci Resolve 20.0, we have taken efforts to keep the project libraries compatible with DaVinci Resolve 19.1.4. While this allows you to access the project library with 19.1.4, individual projects created or opened in 20.0 will no longer be accessible in 19.1.4. We recommend a full project library backup as well as individual project backups before opening projects in 20.0.

If you revert to Resolve 19, none of the projects you've opened in Resolve 20 will be available. So hopefully you have v19 backups of those.

For anyone with render errors, if you'd like assistance, we need a Resolve diagnostics log, generated from the Resolve Help menu, after a render issue.

We also need a project export .drp of the project with the render issue.

And if the project has multiple timelines, details on what timeline you tried to render that had an issue.

Put the files on a file sharing site and provide a link to the files here.

Note that for people on Windows having issues rendering H.264/H.265 files with Resolve 20, if you have the Main Concept codec package installed, it can cause that issue.

The thing is, this project worked in 19. It had some slow playback issues, but all previous projects (some even larger and longer than this project) had similar slow play back issues but rendered without any problems.

But once I updated to 20, now random vfx and clips will temporarily be media offline (and completely random). Sometimes it works, sometimes it doesn't. This video eventually was rendered in about 48 parts in 25-second to 2-minute increments, and then spliced together into the video that was uploaded to YouTube.

To experiment, I created a short 15-second project in both Adobe Premiere (free trial version) and Da Vinci Resolve 20. Both projects were overloaded with 15+ VFX. Adobe Premiere rendered, but Da Vinci Resolve 20 failed at the 4-second mark. My point is, the error is not caused by hardware on my end. Something is causing Da Vinci 20 to struggle with erroneous "media offline".

It is also not codec issues. Like I said above, the project in question was eventually rendered out but in tiny little pieces then tied together into a final video using Da Vinci Resolve 20.

Please, help me identify what I am doing wrong or that I can fix to get back to making videos. Thanks!
