Frequent crashes since upgrading Resolve Studio to 19.1.4

Hi there, I had a great few months with my feature project running faultlessly. It's spanned multiple versions, from maybe 17 to 19. 18 was problematic, but it's a huge project and performance is great since cutting in 20 minute reels rather than a feature film's worth of subclips per 100+ scenes.

The most recent update to 19.1.4 has caused frequent crashes to desktop. Until I did a full clean reinstall and clearing the cache (following recommended procedures from these forums), I didn't even get the Resolve crash notification. Rolling back to 19.1.3 didn't solve. Upgrading OS to 15.3.2 Sequoia didn't solve.

Crash logs here: https://www.dropbox. com/scl/fo/4rejwn8hkn3xwdy3bop6z/AII_5aQN0Izsi4aqDEsqxLc?rlkey=1x8oeq3rpi8hwt7ksjbhw6k2a&dl=0

I'm running a stock Macbook Pro M1, 32Gb RAM, Cache on an external 1Tb SSD, Proxy media on another 2Tb SSD, no bluetooth accessories. HDMI to a 4k monitor.

The only foreign objects in this totally clean install of 19.1.4 are Waves Clarity Vx plugins (deactivated/deleted from tracks). I've not put my LUTs back into the application incase any of them were the problem.

I'm not sure if relevant, but i've noticed my Cacheclip folder reports in Finder as being a few Gig larger than Resolve's Cache manager reports.

I'd be hugely appreciative if someone could take a look at my crash log and give me a steer as to what to try next.

Best,

Will Randall

Sort of unfortunate that you did the clean install before creating a diagnostics log, as now there is only 1 non-crash and one crash log, so not much to compare against.

It's not obvious what caused the crash. Looks like it could be related to deleting nodes in the node tree. Were you doing anything like that when it crashed?

Can you send a project export .drp of that project? And if so, what timeline were you on when it crashed and approximately where in the timeline, if you recall.

Thanks for your attention Dwaine, much appreciated

Here's a link to the pre-clean-install logs, taken a couple of hours before, with crash reports back to 2020.

No, I wasn't working in Color or Fusion. I'm experimenting with Bypassing Color in case the issue is there. I'll let you know if I definitively experience a crash with Color Bypassed.

I tend to be working in Edit. Crashes happen variously when I:
Manually move the playhead to a different part of the timeline.
Play the content from one section another.
Drag half the timeline back to where i'm working to close up a gap, slipping it under a clip (without transparency/blending mode on the top clip)

Most recent crash was 5 minutes ago and I was indeed in the Color tab but just working with a single corrector node, no FX. Elsewhere in the timeline I do have moving Color mask nodes etc, Retimed clips, FX applied to audio clips etc. I work on Fusion comps on a different timeline and render them before inserting the rendered version into the cut.

Obviously, the project is currently rebuilding its Render Cache, but the timeline i'm working on looks to be all blue-lined rather than red.

Further wrinkles: Data Burn In was glitching immediately after I first updated to 19.1.4. The white text was artifacted green on a different part of the viewer, it looked like a flicker artifact until I paused and saw it was the clipname/framecount.
Manage Render Cache also reported a lower cache size than Finder, so there must be junk in my Cacheclip folder it's no longer indexing. I've held off deleting the cache manually but can do so.

Many thanks! I'll PM you a link to the .DRP. Be aware it's a large project, but was stable to work with until 19.1.4

I examined your logs. Some comments:

The Waves components are still in memory and causing problems. I suggest a full uninstall and afterward verifying that no Waves components remain in:

/Library/Audio/Plug-Ins/ (all subdirectories)
/Library/Application Support/Waves/
~/Library/Application Support/Waves/

This doesn't mean you can't use Waves products, but we temporarily must take some steps to narrow down the problem cause.

There are some errors related to the external display. For troubleshooting purposes, please temporarily disconnect that and use only the MacBook Pro screen.

There are huge numbers of errors about "Failed to read "Shaper LUT", sometimes with no LUT stated and sometimes "FilmLooks/3Strip.cube." That could suggest a corrupted LUT reference. Look in your Color page for any nodes using this LUT and remove or replace them.

I don't know if the above will fix it, but it will help eliminate some things.

There are also a bunch of warnings like this:

0x1f27f0840 | SyManager.ListMgt | WARN | 2025-03-26 21:16:59,319 | There is no parameter mark at 0:0 of group Qualifier, timeline id 0, return default at 90000:0 instead

That might indicate it's looking for Qualifier parameters at the beginning of the timeline (0:0) but can't find them. Resolve may be handling this by using default values from another location (90000:0), which could be a fallback position; I'm not sure.

Those could possibly indicate some kind of internal inconsistencies in the project. I'm not an expert at Resolve, so maybe some of the other experienced people could give advice about how to handle possible project database inconsistencies.

Thanks so much Joema,

Yes I spotted those LUT errors, it's peculiar because I haven't knowingly used anything but native/packaged -in-Resolve LUTS, but the project did go over to a colourist a while back for a quick pre-grade to normalise all the rushes and make it more pleasant to cut. They provided their LUT folder from their DR install so maybe there are some problematic custom nodes lurking in the project still.

I'll do as you suggest with regards the Waves plugins, they're unsupported now anyway and i'm not near enough picture lock to doing sound work.

I'll do as you suggest with hunting out dodgy LUT references too. I'm sure the number of timelines using qualifiers within them can be narrowed down to 6, so that should also be something I can track down.

A huge thank you to you both for taking a look. You are gentlemen and scholars on this forum.

[Dwaine Maggart]

Regarding LUTs, after loading the project, on the Reel 6 W5 timeline, it's showing 3 missing LUTs. So for sure there there are LUT's other than the native Resolve LUTs in use. Perhaps those are causing some issues. The 3 I see missing are:

FilmLooks/3Strip.cube
Looks/Thriller.cube
M31 from OSIRUS/M31 - LOG.cube

We've had people with crashing issues caused by speed changed clips using Elastic Wave - Voice mode on the Fairlight page. I see some clips on the Fairlight page in that mode. I'd suggest for any speed changed clips, that you change the Elastic Wave mode from Voice to General Purpose. You can do that by right clicking the clip on the Failight page and selecting the Elastic Wave menu.

Clips with an elastic wave speed change will have this badge on the Fairlight page:

The dev team is aware of this issue and is looking into it. They made a change in 19.1.3 to address it, that did not solve the complete issue. 19.1.4 still has the same behavior.

Thanks so much Dwaine,

I've just added my colourist's LUT folder and tested those 3 LUTS extensively, adding them as nodes and it feels stable, albeit in a different timeline.

I'll move onto testing the speed changed audio. This feels like a good culprit to me as I've intermittently noticed strange behaviours when speed changing audio over the years. Often i'll try 2 or 3 speed changes in succession to massage some sync sound and suddenly i'm left with no sound on the clip. Cache Audio Effects never seemed to rescue it, i'd have to Undo back to the original sound.

I'll keep testing. Many thanks for the pointers.

I'm having a lot of issues with my DR recently and I'm wondering now if it has something to do with the LUTS I also installed yesterday, all I did was add them to the LUT folder that's it

I am on a MAC OS Safari 15.

I too since Wed the 14th all the sudden finding 19.1.4 stalling in the late afternoon (MST in USA). Then when I forced quit and rebooted, it repeadetly stalled opening at 97%. For many of my files. Not even the last one.

I then decided to risk deleting the app off my computer, downloading (from Apple App store). 1.5 hours later it seemed to fix it.

I worked in Davinci from 6:30am-4or 4:30pm MST and again the software just would not load the project. I had thankfully made a copy (but unfortunately not rendered) but that wouldn't load.

I then decided to delete the app again and try to re-upload. I went to the Blackmagic website and saw there was a Beat version 20 -- so spent another 1.5 hours downloading that.

And that did not work.

Now it was 8pm and my video I needed to finish for YT the next morning -- just gone.

I tried again today to delet vs. 20 and download 19.1.4-- and same issue. Not able to open anything and now there is a "!" in a yellow triangle in all of my last videos for last 4 or 5 weeks.

WTF is going on??

right now, I just want to be able to render this video and find another software.

I assume you are using the free version of Resolve?

If you have the BMD version (Not the App Store version) installed and are having issues launching Resolve, logs would be helpful. You can generate those by opening Finder and navigating to:

/Library/Application Support/Blackmagic Design/DaVinci Resolve

and running the CaptureLogs app, which will put a Resolve log .tgz file on your Desktop.

And note that this is the root /Library folder, NOT the /Users/username/Library folder.

---------------------
yes the free version :-0. does the paid version have these issues? I am just not a super technical editor and hope to hire someone else soon anywho..so am wary to invest $300 on software that is glitchy.

But after using another highly suggested tool (PowerDirect) I miss DaVinci!

I am on a MAC...and not this technical. I have deleted most of the stuff from Davinci off my desktop in attempts to reinstall and try again. then deleted stuff again since my hard drive is small and space is prime.

So if you are able to do a 1. 2. 3 step type instructions I hope I can figure this out.

[Dwaine Maggart]

In your Mac Applications folder, if you have a DaVinci Resolve folder, run the "Uninstall Resolve.app" to uninstall the current version.

If you still have the Resolve 19.1.4 installer, run it again to install 19.1.4. If you don't still have the installer, then download the 19.1.4 Resolve installer from the Support site and install it:

https://www.blackmagicdesign.com/suppor ... c%20OS%20X

You'll have to fill in all the user data to download the free version.

After you run the installer, launch Resolve and see what happens. If it doesn't launch, then get a log file as described in the previous message and you should be able to attach it to your post. The log file will have a .tgz extension.

okay tried to do as you said an still not finding any log files. I was able to open my Activity Monitor and get something out of it...but it saved it as a .txt file and tried uploading that and it wouldn't upload.

I finally could open an older version of the video edit but not the more current one.

I can also open a new project.

I was able to finally open import the copy I had thankfully saved...and it did open with what looked like the accurate info -- except there was actually no visuals there. I tried to export the video -- but it went up to 23 hours to render and stalled so I just had to force quit.

It did flash a couple of things up that I took screen shots of but now don't see anything to upload.

I am noticing that I don't get any of the "report" or "ignore" screens lately...and wondering if that is what is needed to generate the log? i am so frustrated and sure you are too since I cannot find anything on my computer with a ".tgz" extension. Nada...

I was able to grab this from the activity monitor. When I have time I will wipe EVERYTHING again from my computer and trying to reinstall and see what happens.

I posted but didn't go through - I was able to to get the file open finally. I did get a crash report but not in the format you mentioned...so I saved it as a pdf but cannot attach it.

hope it is still there tomorrow when I get back in there

[Dwaine Maggart]

If you have the BMD version of Resolve installed, and it ran at all, then there has to be this folder:

/Library/Application Support/Blackmagic Design/DaVinci Resolve

And it has to have the CaptureLogs.app file in it, which you would run by double clicking it.

Again. it's the root /Library folder and not the /Users/username/Library/Application Support/Blackmagic Design/DaVinci Resolve folder, which will also exist, but that's not where the CaptureLogs app is.

Only if you are using the Apple App Store version of Resolve will the above not be true.

agh finally found it. I was copying and pasting the path into my finder and it wasn't returning anything. Not sure how I mised it in my harddrive. Attached

If you can, please share a project export .drp of the S1E11 project.

Open the Resolve Project Manager and right click the S1E11 project and select Export Project, to generate the .drp.

well, I had to close the project because the video was doing something funky and lagging to the sound. Now I cannot get back in. Just tried to upload a copy but says it is too big. even the zipped file is 3.5 MB....Is there another way to get it to you?

[Dwaine Maggart]

You'll need to put the file on a file sharing site, and send a link to the file.

https://drive.google.com/file/d/1lAw_5_ ... sp=sharing

[Dwaine Maggart]

And you'll need to ensure the link does not require access credentials, as it currently does.

I swear I turned them off! okay try now

I've set it to anyone with the link can acces and comment. so I don't know what is going on

[Dwaine Maggart]

Now it's working.

any updates or things I need to try? Was really wanting to finish this video for release Friday morning :-0!

[Dwaine Maggart]

I've asked the dev team to have a look at some unusual errors in your logs to see if that could be related. Waiting for feedback.

okay. to note if needed -- this was happening both vs 19 and 20

thanks for the quick answer

and will you all have a lower price point for people like me in the future. I don't mind paying some but just don't need the entire shebang to my knowledge...and wondering if this would have happened you think with the paid version?

[Dwaine Maggart]

I can tell you that the weird error messages only happen in the free version.

And no, I would not expect a lower price point in the future.

Is there any chance your project was ever loaded in the Studio version, and possibly Studio only effects applied, that are upsetting the project in the free version?

no I don't have the studio version...but now wondering if I should just upgrade?

Could it be a harddrive problem? I know this new Mac book I am on has limited space and I am always having to delete stuff (which actually I did and still had this issue...just tried again a few hours ago and again it just freezes when I go to try to open the project).

I am wondering if I might also get more functionality like I see on PowerDirector 365 for fun transitions and stock photos/videos and stuff?

[Dwaine Maggart]

If your hard drive totally runs out of space and is full, that could cause issues for sure.

Your default cache path is here: /Users/Holli/Documents/YT Vids iCloud/CacheClip

You might check the size of that folder, and if it's quite large, maybe delete it to regain some space.

It sits in my iCloud which has I think 2TB on it. It is saying current size is 1.8MB -- is that large?

It is that I keep the b-rolls I download from canva there for BM to pull from -- which half the time or more I have to reconnect anywho.

The other thing I have done is I keep the same project, but just keep adding new bins for each new video -- so that I can access all the past b-rolls without having to import into a new project...could that be an issue? Is there a way to import b-roll clips I know I will need for mulitiple vids once and use them across projects? I tried looking fora YT on this but didn't find anything

Thanks
Holli

hi just checking in to see if there is any update or answers to previous questions. Thank you!

[Dwaine Maggart]

I suspect the issue is related to using iCloud as your cache path. Not recommended to use Cloud based stuff for that.

1.8MB is not large. In fact, it's surprisingly small. Cache sizes can grow to be 100's of GB. And that can often lead to storage issues.

ugh -- well my hard drive on this MAC ain't big enough. So what then?

Any other news on the file in general?

And what about my other questions? Will I need to not use iCloud if I get the paid version? How much space does the paid version over the free version take?

[Dwaine Maggart]

Then I would suggest using another local storage option for the media and cache. Ideally a Thunderbolt connected option over a USB option, as Thunderbolt storage is more stable.

No significant size differences between the free and Studio versions.

okay is a thunderbolt a special type of external hard drive?
I have a WD that I can connect to my computer

And should I just relocate the iCloud to the harddrive and then change the cache location and see what happens?

Hi any new news?

I was able to start the video over again from a mp4 I had thankfully been able to grab at some point. But today when I went in (in v20) it had none of my media. I tried to relink it but wasn't given the option to relink each file directly since they are in different folders.

And why would I have been able to use DaVinici for 5 months with none of these connectivity issues and then all the sudden it keep doing this to me?

Lastly, I am still not sure what a thunderbolt is? Will Best Buy have one?

I don't want to sound mean in any way - but how about using a search engine to find out more about Thunderbolt? Or straight go to Wikipedia?
https://en.wikipedia.org/wiki/Thunderbolt_(interface)

And about your storage issues - you cannot use your iCloud storage for your cache location. That is storage space somewhere in an Apple server farm. This will constantly sync your data over the internet.

Buy an external SSD drive - for example a Samsung T7 shield with 2 or 4 Terrabyte. It gets connected over USB-C to your Mac and will work fast. Create a folder there, call it for example "Resolve Cache" or something like that. Configure your projects to use that folder for the cache. Be aware that unless you setup a project preset and use that, every new project will default to your internal drive path and you will have to change that.

You can find some very good tutorials on those YT channels to begin with:
MrAlexTech
Team 2 Films
Creative Video Tips

and of course excellent tutorials by Blackmagic themselves:
https://www.blackmagicdesign.com/produc ... e/training

Believe me I have searched and read about thunderbolt but it still isn't really making sense.These things tend to be written for techies which I am clearly not. When I looked on Amazon, it gave me an assortment of stuff like cords and what looked like docking stations.

Is it an external hard drive or just a connection (like a power strip) that makes connecting to a USB-C hard drive faster and more reliable. I'll just go into Best Buy and see if they can explain it in a way that makes sense -- or show me.

I have an external harddrive I already invested in, so with a new project I will attempt to use that and see what happens. Still doesn't make sense why the project would not open and stall the software. I get about having to reconnect/relink the iCloud media since in iCloud...but again I had been doing that for 5 months and only since 3 weeks ago had the issue.

I am assuming when you mention "Be aware that unless you setup a project preset and use that, every new project will default to your internal drive path and you will have to change that."....that I go to "DaVincini Resolve > Preferences > Media Storage" correct to ensure it is doing this for all projects...and then save the media onto the external drive.

I know I am on the free version and don't mind considering upgrading but I just want to ensure I won't have these isssues if I do make that investment

I see. For me that tech stuff has been bread and butter since I was a kid in the 80ties - so I tend to underestimate how difficult that stuff can be for non-tech-people.

What is Thunderbolt?
Thunderbolt is a powerful type of connection used on computers and devices. It looks just like a USB-C port — and in fact, it uses the same shape. But Thunderbolt is much faster and can do more things than regular USB-C.

What is it used for?
You can use Thunderbolt to:

• Transfer big files quickly (like videos or photos)
• Connect to external monitors (even 4K or 8K)
• Use professional equipment, like audio or video gear
• Plug into a docking station (to add more ports)
• Charge your laptop — all with one single cable

Why is it great?

• It’s super fast — much faster than regular USB
• One cable can handle data, video, and power at the same time
• It keeps your workspace tidy — fewer cables needed
• Thunderbolt ports also work with regular USB-C devices, so it’s flexible

USB-C vs. Thunderbolt — what’s the difference?

• USB-C is the name of the plug shape.
• Thunderbolt uses the USB-C shape, but adds much more speed and power.
• All Thunderbolt ports are USB-C, but not all USB-C ports are Thunderbolt.

About Samsung T7 Shield:
https://www.amazon.com/SAMSUNG-Portable ... HP827?th=1

I don't know what kind of external harddrive you are already using, but as the T7 is an SSD it is using super fast flash memory (like in USB drives, but much faster) - similar to the SSD built into your Mac.

The Samsung T7 comes with a USB-C cable and is compatible to your Mac's Thunderbolt ports.

About your last question: The Resolve cache is the place where Resolve does store the temporary files it creates for its own needs. This is not the same as your media folder.

When you put your media onto your iCloud drive - it will transfer the file onto Apples servers. And the system will keep a copy cached locally, as long as there is enough space on your internal drive. And that is the issue here - when your internal drive gets filled up - the system has to pull the data from the internet because it will keep just an empty shell using no space.

It's like a moving box where you put your stuff in and place that into a warehouse out of your home. And to remember where it is, you store a tiny box at your place with the adress and container number of the warehouse. When you need your stuff from that box, you have to drive to the warehouse and get it back home.

okay that makes more sense -- I think :-0! So basically it would connect to my MacBook and then I would have a dock where I could plug in my external hard drive I am thinking? I think still getting to Best Buy and seeing one in person will help me. I am a tactile person.

I have a WD brand external drive. I already spent like $100 on this and since I am not making money on all these videos and venture yet, don't really wanna drop another $160 on a new one. So will try to make this work.

Thanks for your help so far!

If the WD drive is a spinning harddisk, those are quite slow especially for writing data.
If the WD drive is an SSD you don’t need to get another one.

well I tried a bit ago to see if I could create new folders on WD and it doesn't let me create new folders nor drag and drop stuff on there. Is that because it is set up as my Time Machine back up?? Ugh

And looking at the I don't see anything labeld "SSD"...so assuming it ain't one. It just says "my passport ultra for MAC" https://www.amazon.com/dp/B07GKK35BT?re ... in_title_1

Yes, that is a spinning harddisk drive. Not recommend as a cache drive.

okay great to know. thanks!
