When are we going to hear something fro BM? Lots of people having issues with Resolve 19 and in it's current state is unusable.

I've spent 3 days trying to get thing running smoothly with no joy. We can't all have hardware/spec issues. So there are some serious bugs, please get it sorted.

Well, how about helping BMD by posting logs, and if you are on Windows, an NFO file as well.

Can you point to details on how to do that?
Thanks

With a current or new project open in Resolve, click on the menubar option Help, then click on Create Diagnostic Log on Desktop.

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).

Open Windows System Information, and from the menubar, select File > Save (Not a File Export) to generate a .NFO file and save it to your desktop.

Place both those files on a file sharing site (without password protection) and provide links to the files here.

Also, to get a faster response, embed your hardware/software version/ driver version setup in your signature. It will answer many questions to help diagnose your problem faster.

No issues here: delivered a 2-1/2 hour, very complicated documentary last Friday (done on 19.0 and finished on 19.0.1), and just started a new restoration feature yesterday on 19.0.1. No major malfunctions at all on Mac OSX Sonoma 14.5.

same here I'm on linux. Did a 2.25 hour feature that is in the theatres now with 1700 cuts no issues. It would be helpful if instead saying its unusable, help them recreate your issue. My experience has been if you can help them recreate the issue (if its not isolated to your configuration) they will fix it.

after a crash open the project, go to help at the top of the gui then navigate to create diagnostics log on desktop. Send them that as well as a copy of your project (drp) to do that from the projects widget select the project and export it. A recording of the issue is also helpful. use your screen record function or Phone.

Thanks to your precise and detailed description of the problem, the team will get on it right away.

Same here - 4 part docu, each 55 Minutes, remote workflow, editing and color - works like a charm.

Working on a 20 days of film edit and no issues.

No hardware/software info was given to even remotely help BMD to figure out what happens.

Also when dealing with issues between versions, it's good to first start a new project, don't update your older one, just to eliminate probable issues from the update process.

DR 19.1 works very well, no issues. I only had problems with the last DR versions in combination with the installed Mainconcept codec plugin. Since i have removed this plugin, DR is working perfectly.

A while ago there has been trouble with nVidia-Card drivers not cleaning up VRam and therefor running out of memory. It took more than a year for nVidia to fix this problem if I remember correctly.
The temporarily solution for the renderengines like Redshift was to roll back the graphic cards driver to a stable working version.
So maybe the problem is not entirely on BMDs side.

OK. Thanks everyone for the comments, except for the 1 or 2 sarcastic commments.

Here is a link to my Logs and NFO https://www.dropbox.com/scl/fo/n74d9amg ... eemxa&dl=0

I'd be really grateful for any help. How do I make sure BMD see the files?

These will probably help. You also will find many users probably have experienced your issue and may have a workaround. Reading this thread I still have no idea what problem you are having. Blackmagic have millions of users so generally posts that give no information will be skipped because unless they can read between the lines it’s a waste of valuable engineering resource. Help them help you.

1) Try editing your subject so it’s short and describes the issue. You can use the help of ChatGPT if your finding it difficult to summarize.
2) go back and update your first post and describe clearly what your dealing with. Include your computer hardware and operating system information.

Hello,

I have exactly the same problem. Since the installation of Davinci 19, the software is almost unusable. I have a Mac studio 2022 Apple M1 64GB running Sonoma 14.6.1. The playback of a clip is constantly jerky and the sound turns on and off / right and left randomly. So we can neither see nor hear. Also, my rendering times are 6X longer.

My logs : https://we.tl/t-B6lJQuYJcE

I hope the Black Magic team will solve the problem quickly!

For those who are on mac and for whom there is no problem, are you also on Apple M1?

Best regards

You can see my signature. Studio Max M1 works fine just editing a 2 hour 30 min show no problems GH6 and GH5S 59.94P 10 bit Vlog. Installed software is only Topaz Ai, Affinity Photo2, Resolve Studio 19.0.1, and Chrome. No plugins. It is only used for editing so no other uses. No iCloud etc. Project is usually transferred to PC for finishing.

PC has a lot more software but still runs full speed for files it can decode but does not load USD.plugins warning at startup. This is also the case for the free version running on the PC I use for email etc. Editing Threadripper PC has EDIUS WG 9 and X, Vegas 18, DVD Architect for authoring, SoundForge , TMPGenc MW, Affinity Photo2 and Topaz, maybe some others as well as some VST plugins that came with various version of Vegas that Resolve does pick up.

Both PC and Studio Max use same Logi Bluetooth keyboard and mouse. Speed Editor is connected with USB cable to PC and Bluetooth to Studio Max. One at a time of course but cable is almost always connected to PC . PC is Win 10 Pro 22h2 and Mac is Sonoma 14.5 both PC and Mac up to date as of yesterday.

I have an M1 Mac, Windows PC, Linux system, and M2 Pro Max, and I haven't encountered the issue you're describing. However, I should note that I don't work with consumer formats. Could you specify the file type you're having trouble with? It would be helpful if you could upload a sample clip and a .drp file that demonstrates the issue. Without these, it's challenging for anyone to investigate and address a problem that may be difficult to reproduce.

Thanks. It's an MP4 from a Canon C200. If I upload a clip it won't show the timeline problem. It Plays fine in all the other pages and in full frame. It suggests the issue is with the timeline somewhere?

when I get some time later Ill look for demo material and see if I can reproduce the issue.

@Philip: Can you explain your issue in more detail please?

And yes, if it's related to some specific file or files, if you can provide a Resolve Project Export .drp of the project having the issue, along with the clip or clips, that would help to diagnose the issue.

To make a project export .drp, in the Resolve Project Manager page, right click the project and select Export Project.

@Justan: Assuming the most recent P199 related project you had loaded is exhibiting these issues, please send us a project export .drp of that project.

The playback of the clips has kept changing. Initially they were playing back in slow motion with the audio cutting in and out and oscillating. Now they are playing back at normal speed but very jittery. The audio is not quite in sync.
The clips play normall in full screen and in the other pages, the issue just seems to be on the timeline.
I've tried the clips as proxy's and the issue is the same.

The .drp file and clips are here https://www.dropbox.com/scl/fo/1fymqqs6 ... xcrxj&dl=0

Please let me know if you have any problems or need more info.
Thank you

Im not having any playback issues using your drt and media on my 24" 2021 M1 imac with 8 gigs ram playing from a sandisk extreme ssd drive, operating system sonoma 14.6.1 also tried it on a hp g2 windows 11 with a 3080ti also played perfectly. I dont think my prefs on this system are very different from default. I tried turning off h.264 and h.265 hardware acceleration (which was on) and playback was just as good for me.

Looks like you provided a timeline backup .drt file, instead of a project export .drp file.

Please provide a project export .drp file, as it may have project settings that are not reflected in a .drt file.

Thanks. I'll see what Dwaine comes up with.

On my significantly less powerful desktop Windows system, your project plays back fine on the Edit and Color pages. As it should, since you have no grades or effects on most clips, and the one clip with a grade is a simple grade. I even have the media on a spinning drive, not an SSD.

The NFO file shows you may have one of your 2 displays connected to the onboard graphics and not the RTX 3060Ti. How are the 2 displays connected? They both need to be connected to the RTX 3060Ti GPU. If one of the displays is connected to an onboard graphics connector, that can impact Resolve performance.

I'll also note that the Intro_C2_1.mov DNxHR SQ 960x540 file was not provided, so clip 5 on the Color page timeline if offline for me, so I can't tell how that would play back, but it should be much easier than the UHD H.264 files to play back.

It too plays fine on my old 3770K PC with a 1080Ti. Like Dwaine the files were missing. Also like Dwaine files are on an old 2T hard drive. I have not tried on my other more powerful PC or the Mac as I am sure they will have no problem if this old PC plays them. Will check later though for completeness.

I had no issues with the YT-1A project either. Playback and even scrubbing was at 25 fps.

GTX 1070 8GB

I'm going to revise my opinion. As I keep messing with the project, I start to find on the Color page, scene 4 starts to stutter and drop out of real time playback. That clip has a simple grade on it. If I bypass that grade, the issue goes away. I also see that if I turn off hardware H.264/H.265 decoding, the issue does not occur.

I've got a GTX 1050Ti on this system, and I've got a bunch of other apps running, which could be having an effect. But this is not behavior I expect to see.

I'll keep testing to see what I can pin down. But I'm curious if the issues you are seeing are on the Color page scene 4, when they happen?

In the meantime, go into Resolve Preferences - System - Decode Options, and deselect "Decode H.264/H.265 using hardware acceleration" and then save the preferences. You will need to restart Resolve for this change to take effect. After doing that, do your issues go away?

I reset grade on all clips because I was noticing more of a lag on clips 1 and 4, I was trying to determine what was causing that. with nodes reset they were still slower to scrub through compared to clip 2. I kept scrubbing , muting clips, generally playing about, in the end I was getting a lag between pressing play and the video playing, 1 second at least lag, this lag happened on video+ audio, video alone, audio alone, and areas where there was no media

Nothing interesting in task manger relating to increase in ram or vram use or cpu or gpu processing.

EDIT: I thought i'd try this again with screen recorder running, but after 5 minutes of doing the same as I did previously can not replicate the 1+ second lag between pressing play and playing starting.

Thanks Dwaine, and others. It's early morning here. I'll absorb the info and try things out and report back what I find. Your help is much appreciated.

@Dwaine
Both displays are connected to the Graphics card. I just double checked that, not sure why it's indicating otherwise.
I've added the missing clip now. It was due to the storage limit on my Dropbox a/c. I removed one of the less important dji clips to accomodate.

The clips are playing fine for me on the Color page, no issues. If I bypass the grade the issue still persists on the edit page.
I've deselected the @decode H.264/H.265 using hardware accelaeration' option. No difference.

Checked latest download on all my machines and they all seem to play fine in CUT, edit and colour pages. However I noticed that there was a very slight delay in lip sync on clip 4. Happened on all machines. To recap my email PC an old 3770K 1080Ti with the free version of Resolve 19 then the two in my signature. Both PC's show failed to load USD.plugin at launch.

I do not normally use proxies so checked what the project has set. It is set to prefer proxies so I reset to originals and the lip sync is now correct, instant playback. Happens on all three machines. These files are also not the originals but exports from Resolve so we may not be seeing the effect of the original files.

If I reset to Camera Originals I'm back in slow motion and audio out of sync. Really don't know what to try next. Perhaps a full unistall of Resolve and GPU drivers, then reinstall?

Have you tried starting a completely new project using the most troublesome file ?

SkierEvans wrote:Have you tried starting a completely new project using the most troublesome file ?

Funny enough, this was a new project after having the same problem earlier. At first it worked as normal then reverted to the same behaviour.

Thanks.

I tried your YT-1A project on my M1 Ultra Mac Studio running Resolve Studio 19.01 and don't see any playback performance issues. I examined your logs and don't see obvious major problems. There are lots of "noise" warnings such as "No reply received from file system, assume successfully deleted folder" and "Timeout waiting for interop lookahead", but those appear on my own good-running system.

The Resolve caching system is sophisticated. If this is not fully disabled when doing performance tests, you can get varying results where it seems intermittently slow then fast. If others testing this don't use the same cache and playback config, they could also get differing results due to cache effects.

When testing things like this, I suggest doing this on the Edit Page:
- Disable proxies (Playback>Proxy Handling>Disable All Proxies
- Use full res or everyone agree on a specific timeline playback resolution (Playback>Timeline Playback Resolution>Full)
- Disable Render Cache: (Playback>Render Cache>None)
- Delete existing Render Cache: (Playback>Delete Render Cache>All)
- Disable Fusion Memory Cache: (Playback>Fusion Memory Cache>Off)
- Disable Background Caching: (Project Settings>Master>Optimized Media and Render Cache>Enable Background Caching (clear checkbox to disable)

I have decode acceleration enabled in Resolve Preferences>System>Decode Options. On a Windows machine, you might have other options such as QuickSync or "Native" or "NVDEC". Each of those should be tested.

This is a very simple timeline and almost no effects are in use. I don't know why it would suddenly have problems on Resolve Studio 19.01.

Just to clarify, this IS a playback performance problem you have observed is new to Resolve 19 which did not happen in prior versions on this same material and the same hardware? We are operating under the assumption that Resolve 19.01 is unusable in your scenario, but past versions on the same firmware, hardware, media and timeline ran just fine. Is that correct?

Hello,

I can't send you the P199 project but here is another one that poses the same problem. https://we.tl/t-sJIz4YCtgC

This project just contains end-to-end rushes filmed with A7SIII. I tried unchecking the H.264/265 decoding option with hardware acceleration. After restarting the software, the playback worked perfectly for 10 seconds and then after "pausing" and restarting the playback everything went back to the way it was before.

Best regards

Not sure if I should just go for a full unistall of resolve and the Nvidia drivers and attempt a new clean install?
Just a bit concerned about losing projects and settings.

I've already tried several complete reinstallations and it hasn't changed anything. You can save your projects individually but also save your project library before reinstalling.

Maybe I missed something but I don't see anything in your project that jumps out as causing issues. I expect your media is 422 10-bit which won't play back smoothly without hardware decoding (guess). Could you provide a sample of your media? Also - if you only had a single clip in your timeline, does it also struggle?

@Dwaine What do you reccommend to resolve this situation? I need to work and I've not being able to for almost a week.
Should I do a clean install? I can't think of an alternative, other than revert to Resove 18.

Attached is a rushe extracted from my project as well as a video made with my mobile phone that shows the playback problem. This problem is general and appears on all my projects. I have many projects filmed with an FS5 in 8bits and the problem is still there. The only way I found to be able to continue editing is to create optimized media in prores422 LT and display the screen quality in half or quarter. And even by doing this, when I make a cut and restart playback the same problems reappear. All these problems have occurred since version 19. I am almost every day on Davinci Resolve and I can clearly tell you that with version 18, playback was ok.

Maybe the problem can come from my computer. However, I did a complete check with several antiviruses, I did a thorough cleaning and I did the updates.

I also tried to put only one shot on my timeline, the problem is still there and it doesn't matter if H.264/265 decoding is enabled or not.

Thanks

I spent lots of time studying your case and trying to reproduce the problem. I finally determined your version of Resolve Studio 19.01 is somehow being forced to run under x86 Rosetta emulation. That will definitely cause performance problems.

The Resolve executable is a universal binary that contains both arm64 and x86_64 executables. On an Apple Silicon Mac, it always runs the arm64 version -- unless something forces it to run the x86 version under Rosetta emulation. For some reason, that has apparently happened on your machine.

This can be determined by examining the first line of the first debug file. It should say this:
Running DaVinci Resolve Studio v19.0.1.0006 (macOS/Clang arm64)

However on your machine it says this:
Running DaVinci Resolve Studio v19.0.1.0006 (macOS/Clang x86_64)

IMO you should NEVER run Resolve under Rosetta emulation on an Apple Silicon Mac.. Sometimes this happens because a plugin manufacturer (after four years!!) still has not made an Apple Silicon version of their plugin. They sometimes tell customers to just run Resolve under Rosetta, which enables it to use the prior x86 version of the plugin.

You can determine if this was done by using Finder's "Get Info" on DaVinci Resolve.app, and inspecting of the checkbox is set for "Open using Rosetta".

This can cause problems that later materialize, as this situation makes all too clear. Lots of time can be expended troubleshooting those, but the original person who made the Rosetta recommendation never faces the consequences of what they set in motion.

Do you have any idea why you were running Resolve Studio 19.01 on your M1 Max under Rosetta emulation?

Since upgrading to Davinci Resolve 19.01 I am experiencing the following:

1) constant memory leaks until the application crashes, the system monitor shows the memory usage growing from 5GB to 76GB, even after generating proxies.

2) Media offline messages (the project is stored on a Samsung T7 SSD)

3) Rendering ready for upload to YouTube now runs a 2 frames a second, resulting in an estimated 17hr render for a 24 minute 4K project.

My system is a M2 MacBook Pro, 16gb ram, macOS Sonoma 14.6.1

Any suggestions before I throw in the towel and revert back to 18.06
