Media Offline (but it's not) bug Beta 5 & 6 Resolve 15

I'm having trouble with Beta 5 & 6 of Davinci Resolve 15

I have a project where most clips (and thumbnails) will briefly flash "media offline" even though it's clearly not as it's playing the file. The media offline message does not reappear in the same places when replaying the clips which would rule out corrupt clips. The message can appear once or a dozen times during one clip, then playing it again, not appear at all.

Things I've tried:
1. Deleting the cache
2. Deleting optimised media
3. Removing all clips and reimporting into project (well, like 80% of them to avoid losing all editing work I've already done)
4. Enabling/disabling thumbnails
5. Upgrading from Beta 5 to 6
6. Exporting the project, starting a new one and reimporting the project

Ideally there's a solution out there. Starting from scratch is not one of them though, too much work has been put in.

Cheers

Does the issue only happen when you are using optimized media and/or caching? If both those are off, do you see the issue?

What type of clips?

Use optimised media was selected. I have tried disabling it but the problem persists. The footage was shot on a Panasonic GH5, MP4 approx 100 megabits setting (although comes in at around 77 megabits), 25 frames per second (some clips 50 frames per second).

I had the same problem in my Dell alienware laptop, and have a friend who has the same in his desktop.
I didn't found any solution....

Here is an extra data point.

Today's occurrence was 3 mins into editing a timeline.

+) Opened Resolve (defaults to open last project)
+) No Optimised media
+) Performance mode was ON. Proxy_mode = Quarter
+) 2 clips on the timeline with Fusion effects
+) Background rendering = after 1 sec
+) Footage & Database on external ARECA raid over Thunderbolt raid
+) Cache on system SSD
+) Type of footage : 8K R3D (Monstro)

Then I turned Proxy_mode = OFF

+) After caching 3 clips : I got Media Offline.
+) Restarted Resolve => Same error (media offline)

I am able to see the Raw R3D footage (using FCP X, and REDCINE-X) and can play it on the external RAID (so this is not a macOs problem)

ATTACHMENT 1 : Here you can see it After Resolve had been rendering for 2 mins.

AJ

After Restarting Resolve.

Media still offline - and a new error (in the diagnostic tab)

AJ

More info.

+) App restart did not fix this
+) Switching to a database on the same disc accessing the same R3D -> Plays with no issue
+) Switching back -> media offline

PLAYING the OFFLINE media -> makes it appear -> Pausing it returns to 'MEDIA OFFLINE'.

This reminds of the the R3D bug reported relating to the Metal driver that could play the footage but displayed corruption only when the Playhead was paused.

ATTACHMENTS

+) Currently using OPEN CL (which I note has the 'corrupt frame issue that only only saw on METAL in Beta5)
+) You can see the footage when you are playing
+) Media offline when you stop the playhead

AJ

I found another Database on the same Raid.

On that one - in the Timeline :

+) Media OFFLINE when Playhead Stationary :
+) Media ONLINE when Playhead is Moving

(is the opposite of the my earlier experience)

AJ

Took the Raid DB offline.

Copied to System SSD.
Local Copy (system SSD) of Footage

Playback in Resolve ==> Media OFFLINE issue

MISC : This is a DB with a single Timeline, single R3D clip

AJ

Next : To see if this is a Database corruption.

+) Rebooted machine.

+) Opened Resolve -> Now single clip in SSD Database -> PLAYS OK now (relief!).

+) Tried to Switch to another Database -> CRASH.

AJ

OK - Everything is working again.

Conclusion :
+) Restarting Resolve does not reset its ability to determine if MEDIA is connected.
+) Rebooting the machine resets whatever it is that is causing this bug.
+) Most importantly : NO Database is Corrupt

This issue has only surfaced after I have started using FUSION.
A slow trail of diagnostic messages could mean there are teething issues that need to be addressed

I have a project where most clips (and thumbnails) will briefly flash "media offline" even though it's clearly not as it's playing the file. The media offline message does not reappear in the same places when replaying the clips which would rule out corrupt clips. The message can appear once or a dozen times during one clip, then playing it again, not appear at all.

This sounds a lot like the problem I have with V14 on my new laptop, an i7 7700HQ, 24MB RAM, GTX1070. I spent quite a bit of time on the phone and Team Viewer with a Resolve tech support person in Singapore and she couldn't solve the problem.

It seems like Resolve is having trouble decoding some H.264 frames, but only on my new laptop. The same project and files work fine on my old, lower spec laptop and my desktop.

@Mike: If you are using the Studio version, did you try unchecking the "Decode H.264/HEVC using hardware acceleration" checkbox in Resolve Preferences - System - Configuration, and saving the prefs and restarting Resolve?

I don't remember for sure, but I think the woman from tech support would have tried that. She did lots of things including in the prefs window.

At the time (a few weeks ago) I had to get a project out ASAP and ended up rush-building another machine to do that. Now that I'm doing all my work on the new machine I was able to install the V15 beta on my laptop to play with it. I just loaded that particular project into V15b6 and it doesn't have the problem. So I guess my issue wasn't the same as Antony's. It seems whatever it was is cured in V15.

When I open resolve 15 this is what I see. granted the project is actually fine. All the clips are present its just annoying seeing this. This " Media Offline" issue occurred when i was doing noise reduction on the timeline and Resolved crashed. When i did a force close and restart Resolve I get the media offline in the project explorer.

I don't remember what made the second project crashed but once resolve 15 crashes while a project is open it will show me "Media Offline"

Hope this might help the community

I'm having this same issue in 15.2.2 Studio. It's happening when color grading RED or Quicktime Prores 422 clips. Proxy mode off, not using optimized media. It happens when I navigate clip to clip, the first frame will say "Media Offline," but when I scrub through the clip, it's actually there. I can make color adjustments. But it will randomly say media offline. Application restart temporarily fixes it, but then it starts happening again after a few minutes.

I had another bug in 15.1.2 where my custom keyboard shortcuts would suddenly stop working.

How is 15.2.3?

Mentioning R3D footage, you may have some bottleneck in the system, like access time or transfer speed.

@Dwaine's solution above worked for me. I was getting random flashes of Media Offline during clips as I was rendering - but this seems to have solved it for me.

If you are using the Studio version, did you try unchecking the "Decode H.264/HEVC using hardware acceleration" checkbox in Resolve Preferences - System - Configuration, and saving the prefs and restarting Resolve?

I now have this same problem with 15.3.1.003 and none of the ideas worked here... The clip I am using is totally fine.. plays normally in all other apps... I created a new project as well, and same thing... This makes DR pretty useless right now.. did a ton of other projects with it with no problem...

Have to use another editor for this issue now...

Are there any plans to fix this bug?

What type of clip are you having an issue with? What is the codec type and file type and resolution?

The free version of Resolve does not decode some codec types that the Studio version works with.

If you'd like to provide a link to a file that is not working, we can verify if this is the issue.

Hello Dwaine,

It's footage from my mavic pro... MP4, AVC Long codec....4k.. I've used this format many times before with no problems.

It plays back fine in other players.. In the timeline in DR, it shows valid frames then the "Media Offline" sprinkled in... Same on playback... Some frames ok, then "Media Offline"

I used Hitfilm to edit what I needed and that had no problem...

Hope there is a work around for this!
Thanks
Harold

It's footage from my mavic pro... MP4, AVC Long codec....4k.. I've used this format many times before with no problems.

My opinion is that this is a bad format for post-production. Convert it to a simpler format like DNxHR or ProRes and you'll be a lot better off.

Dwaine is (as always) correct in that Resolve Studio will play back more formats than the regular free version.

I have had this happening ever since I started using DR a couple of months ago. I don’t do anything fancy just editing MP4 clips in the timeline. To resolve it I slip the offending clip onto another track. This seems to refresh it or something and it usually is ok when I pull it back to the original track. It is very weird and can become a bit of a pain. I was hoping that version 16 had sorted this out but I am afraid I can’t get 16 to open on my PC. So I am stuck with it!

[Dwaine Maggart]

@Harold: please provide a link to a sample clip that is not working.

Nigel, what are your computer specs? Never had problems like these here.

ok, but it only just started happening after using that same format a couple of dozen times with no problem....

I'll try it though...

Sorry I am going to be offline for a week or so. I will try to post this when I get back.

I am having the same issue as DoItNow, first when using the latest Version of Resolve 16 on my laptop, then still after exporting the project to my PC (AMD Ryzen Threadripper 1920X, GTX1080).
Some clips are shown and rendered as "media offline", but when going through the timeline frame by frame, all frames are there and playing the clip separately works.
Moving the clips in question up and back down in timeline, seems to refresh the preview, but doesn't help solving the problem, as the render output is still having the described problem. Not to mention that the clips are broken again soon after continuing working.
I am editing MP4 clips, which are located directly on the SSD of my PC.
I also tried rendering with and without "Use optimized media" and "Use render cached images", also treid lowering the render speed from Maximum to 10, nothing helped.

Same Same here on v16 beta2. XAVC footage all of a sudden. Going to try some of the fixes recommended:

Reboot didn't fix it.
Moving to another track didn't either.
No luck unchecking .h264 decoding.

Can fix manually by right clicking on clip, Find in Media Pool, Right click, Conform Lock with Media Pool Clip. Deleted unused render cache as well. I had to fix a dozen clips this way.

I have Render Cache Color Output enabled for all clips which I had never done before. My cache SSD ran out of space. Could be the cause.

And ewww baby, don't run the netflix app while you are rendering, lol! Instant fail.

@Dwaine Maggart I have the same issue with davinci resolve studio 16, i tried formating my pc with a fresh copy of windows, it worked fine for a moment but the issue started again, i think when the program crashed and had to force stop. I tried davinci studio 15 and it s the same. I tried also checking and unchecking the decoding H264 with GPU, and still the same.
I have an alienware 13 R3, intel 7700HQ, GTX1060. camera: GH5, shooting in MOV (tried MP4 too and it also happens), H264, 4k, 24p.

The title of this thread is "Media Offline". Is that your problem? Or is your system crashing?

If you are having crashing issues, please provide a Resolve diagnostic log file and a Windows System Information .NFO file and a Windows dxdiag file. Details for all that are here:

viewtopic.php?f=21&t=90190

If your issue is that certain files are just not appearing in the Media page area, then send all of the above, plus a link to a sample file that is not working.

@Dwaine Maggart The problem is that DaVinci actually render those "media offline" frames into the final project. Even if i loaded the clip again, it was still rendering the same frame as "media offline". I was able to get away by deleting the project and starting all over, but that solution only worked with the fresh copy of windows. If i have the same error again on a clip I will make sure to upload it

Same Issue here. Resolved (if you'll excuse the expression ) buy copying offending "media offline" clip and pasting onto a new track. I was able to render successfully. Running Resolve 15 free version on Dell PC.

@Dwaine Maggart I got the same problem again when I tried davinci studio 16 beta 4 and i was able to upload a clip that renders with the "Media offline frame" no matter what i do. This started after a crash of the software and it s making Resolve almost unusable because it ruins several clips when it crashes. It happens more on resolve 16 than 15 though.
Here is the link to the corrupted file:

We'd still like to see all the requested system info and logs.

It's not possible for Resolve to corrupt source files. Are you referring to files being rendered when it crashes becoming corrupt?

Having a corrupt file is not helpful. We need a non-corrupt source file that is causing the Offline frames in a render. And we need a project export .drp of the project, so we can replicate the render scenario.

We need the logs and system info NFO to replicate your hardware and software scenario as closely as we can.

@Dwaine Maggart this is what is actually happening, resolve is corrupting source files when it crashes. that specific clip was corrupted by resolve, after a crash. I already knew that resolve does this, so i did a backup before starting the project, so I also have a non corrupt version of that same clip.
You can easily replicate the rendering scenario just by adding that clip to the timeline and render it in the youtube 4k settings on mp4.
How do i retrieve the infos and logs you need?
thank you

[Dwaine Maggart]

You would retrieve all that info by following the link in the section where I asked for all that info.

But for Windows, the TL/DR version is:

In a File Explorer window, go to:

C:\Program Files\Blackmagic Design\DaVinci Resolve

and run CaptureLogs

This will place a Resolve log file named similar to this on your Windows desktop: DaVinci-Resolve-logs-20181228_140434.zip (You may not see the .zip extension if your system is set to hide known extensions).


Then open Windows System Information and do a File - Save (Not a File Export), which will generate a .NFO file.

Place both those files on a file sharing site and provide links to the files here.

Hi DVR Forum!
@Dwaine Maggart, could you tell us the process for MAC ?
I have the same issue here, Media Offline (exemple : P1322164 [12074217 +3717].mov).
They are all Optimized files ? The files that I can't find have all "[12074217 +3717]" this kind of info on the name file.
Many thanks for your help
Bruno

If you deselect the "Use Optimized Media If Available" menu in the Resolve Playback menu, does your media come back?

Mac logs can be generated from the Resolve Help menu "Create Diagnostics Log on Desktop" menu.

Mac system info .spx file generated by selecting About This Mac in the upper left hand corner, then System Report, then in the System Information menus at the top: File - Save.

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

HEVC Codec trouble...

Install it and it works then.

@Bruno: My initial thought was that those characters []+ in the file name were the issue, but naming a file here the same is no issue, so it's not that.

Please provide a link to one of those files that shows as offline, so we can see what it does here.

I have exactly the same issue which is extremely concerning. I have to deliver a feature film on Wednesday and on a viewing export we discovered 83 offline stills!!

The project was shot on BMD Ursa 4K on CinemaDNG, everything was fine until I have exported and suddenly there are many corrupt frames, and now, the corruption is on the frames in finder!

On the Pro-res export for the offline it is all good, no signs of corruption whats so ever.

I have moved between DR15.3 to all of the 16s and now on beta 16.6..

I think that Resolve is corrupting the footage. this is very serious business.

I have uploaded the corrupt frame

I'm glad I'm reading this thread as several of my cameras were exhibiting this annoying offline b.s.. I thought it was due to dropped frames using the hm170, ursa broadcast and af100.

my W7 davinci 11b4 freezes at least 6 times a session but bm indicates on this thread that crashes can't corrupt source files during editing but crashes during render outs can corrupt source clips. Right ? I never get crashes during DRS render outs, I only get crashes during editing. Obviously DR S is corrupting source files but why and how ?

That's depressing. However I kept the original source files so all I have to do is re import the files affected and re edit that portion of timeline and do a fresh render out (and hope no crashes in process).

I think that this is major issue, this is supposed to be a non destructive software and it is proving to be false!!, I have very upset clients at the moment and we are trying to go through to the back-ups to replace the corrupt frames.. so far we identified 83 of them...

Can you re import all the raw files and try another render out ?

Patrick

Can you re import all the raw files and try another render out ?

Patrick

Production and myself are working on importing only the offline / corrupt frames as they are uploading it from another location, replacing the frame in the image sequence location to see if it will solve the issue... reconnecting to a 'good' frame
it's going to be a process (the davinci software delaying our delivery by two days)! This is absolutely madness and I am not sure how to approach it in the future..

As Dwaine has mentioned before, it's literally not possible for DaVinci Resolve to touch your original source files.

Media Offlines can be caused be several issues -

• an already corrupt source file
• an unsupported codec or format. Please note: just because it plays in VLC does not mean it is guaranteed to be picked up by Resolve. Windows 7 has multiple issues with codecs and we do not support Windows 7.
• a changed path - this includes disconnected disks, moved folders, drive paths that change from F: to G:
• potential issues with cached or optimised media
• if your codec is BRAW, using an older version of Resolve to read newer BRAW clips

The listed URL - viewtopic.php?f=21&t=90190 - is an FAQ that lists several resources that you can use to narrow down the issue - what are the list of supported codecs, where do I download specific versions of Resolve, how do I grab logs or export a project for debugging, what info is needed when posting a bug report (for each platform) so that the other users can help you.

Thank you for the list Shrinivas, please let me clarify:
1. The footage is from a BMD Ursa camera 4K
2. We are running on a Mac OSX - I have attached the DR logs before
3. The file path has not changed since the start of the project, and if files should be disconnected (did not happen in our case) a reconnection should not in any case corrupt files?! / frames!? And if it does, please explain how? And why?
4. The export for the offline edit are clean (done on a davinci system on another mac) therefore original files were not corrupt (we will know more in a few hours when we get the frames from the back up files
5. Potential issues with cashed or optimised media? Am I giving Resolve permission to corrupt the media? Is this a destructive process? I thought it is a non destructive software?
6. The codec is BMD DNG raw
7. With regards to debugging and communicating with BMD, I am on a 'survival mode' at the moment, trying to export the film out by tomorrow to be presented at a film festival for it's world premiere ... all that instead of finishing the grade.
8. Another issue that I keep forgetting to mention, some of the red offline frames are semi transparent with the image showing behind.. which brings me to think why can't I choose to remove the option of the red frames and let me see the corrupt frame instead.. this automated 'offline Red' frame if worse than a corrupt frame showing, it should create a special marker instead?

I would love to hear a technical answers with a solution for this (in my POV) a major issue that need to be addressed urgently by BMD.

Kind regards

From your logs, I can see multiple entries like:

Code: Select all

Could you specify what you used to generate the offlines? Could you also take a look at your RAID/storage controller logs to see if there are issues on the storage side?

A link to a couple of sample DNGs (originals from the camera and generated offlines) would help narrow down the issue as to whether the issue happeend upstream.

To be more specific: All disk related errors from the logs in your last couple of sessions point to paths under /Volumes/LRO - online RAW 1/. Other disks and connections (like backup projects mount) seem to be ok.
