Total Black when using Depth Map

I have tried using the Depth Map and almost every time I get nothing but all black when previewing. I say almost every time because it did work for me once. But after closing Resolve and reopening it later I could not get it to work again (using the same clip). Has anyone else seen this?

I have similar experience on my Windows PC.
New Project - Drag a .jpg picture to timeline in Edit Page
Drag "Depth Map"from Effects over picture in timeline
After appr. 2 seconds Viewer gets dark
No change when scrubbing over the timeline (while GPU load raises to appr. 80%).

I haven't used that yet but you do need to set your near / far range (assuming you haven't.) I'm guessing it's not interpreting any foreground elements as foreground.

Using Default settings. Not checking the box.
Even if I check the box and set them to max limits, I get the same.
I have messed with it some more and have found this.
If I use a JPG and drop it directly into Fusion page I can then get it to work.
If I try the same with a video clip, it will not work.
If I put the JPG on the timeline and try to use the Depth Map either on the timeline or in the color page it will not work.
A video clip will not work on the timeline or color page either.
I suspect this is somehow related to the Video card. It is a GTX 1660-TI in a laptop. Perhaps it is under powered or needs some settings changed (although I have tried MANY things without success).
I was hoping BETA 2 would behave differently and maybe reveal the issue.
Unfortunately it behaves the same.
I can provide more information if anyone at Blackmagic is interested.

Same problem for me. I tried first in the edit page, then in the fusion page but nothing happens except the appearance of a completely black screen on my footage. When I wait for a few minutes nothing more happens.

I have similar issues with some clips. Similar hardware. I had disabled one of the video cards a few weeks ago in pursuit of resolving DR issues, but on this issue continues. I am going to step up to the 512.59 studio version of the software to see if it helps, although it looks like you are already on the later version.

No change in behaviour with Version "DaVinci_Resolve_Studio_18.0b3_Windows".
Sometimes Davinci Resolve crashes after dragging the "Depth Map" over a .jpg in the Edit page.

Additional Info: I have two monitors connected to my graphic card!

Hi
I'm also owner notebook with GTX 1660 Ti with same problem in Resolve 18.* in effect Depth Map.

First of all, thanks for this topic, that I'm not alone and your experience was useful.

I noticed that the black screen did NOT appear only when NTSC 740*480 was selected (all other project resolutions and timelines result in a black screen). I tried to select the NTSC 740*480 project and make the timeline higher in resolution - still a black screen.
Turning on the effect Depth Map in EDIT or Color Tabs has no effect - the behavior is the same everywhere.

Now the good news and the fun ones.

The update 18 beta 4 has come, where it became possible to add an effect Depth Map inside the Fusion.
If you open a clip in Fusion (meaning that it will be at its original resolution), then the effect will NOT be applied and there will be a black screen. This is what we expected.
But we know that for the NTSC 740*480 timeline, the effect Depth Map should work. I try before the effect Depth Map to add Rasize node and set it to 740 * 480- It works!
So then I start moving the sliders in Resize manually and it turns out that the effect works at certain proportions and the resolution can be increased even up to 4k.
Checking:
-I set up the project to 4K - add the video in Timeline- go to Fusion and add Resize node and before the effect Depth Map- The screen is still black
-In Resize node move slider smoothly in any direction - WOW! we has got a depth map!
Of course, the image is distorted, but this is a matter of technology
Do it other way:
- Add background node (equal timeline resolution, 3840*2160)
- Add Merge node- our file (3840 * 2160) in foreground and then connect to Depth Map node. (in the current resolution we still have a black screen)
- Will increase the size of the background on one side, for example, the width into 3888 * 2160 - WOW a depth map appears!

I've been playing with both Mac and PC versions of resolve 18b4 and the depth map. There appears to be a difference between the two application platforms functionality. I wanted to create a parallel path for the depth map node and connect the output into an alpha in trim node on the main node path. When I do this, I get a solid white preview that does not change as I try changing depth parameters. On the other hand, it works as expected on my MACbook. This is behaving like a bug in the Windows version.

Do it other way:
- Add background node (equal timeline resolution, 3840*2160)
- Add Merge node- our file (3840 * 2160) in foreground and then connect to Depth Map node. (in the current resolution we still have a black screen)
- Will increase the size of the background on one side, for example, the width into 3888 * 2160 - WOW a depth map appears!

I was also able to get this to work (not consistently and on a 1080 timeline).
I found that if I set the width at 3988 (or above) or 2253 (or below) it works. Anything in between does not.

There is something obviously not working correctly here since it CAN work and DOES work occasionally but most of the time fails.

As yet another example, the other day I installed the Game driver instead of the Studio driver. I tried the Depth Map effect and it worked fine on a 1080 time line with two different clips (UHD BRAW). I closed and reopened Resolve and tried the exact same thing with the exact same clips. Didn't work.

I just posted LOGS and Project Archive for BlackMagic to look at. I missed a PM asking for these so unfortunately they are bit late, but hopefully someone will be looking into it.

So the above got me thinking.

I tried putting a UHD clip on several different timelines. Here are results:

Not working:
1920 x1080
2048 x 1152 16:9
3840 x 2160

Working:
1828 x1332 Academy
1998 x 1080 DCI 1.85
2048 x 1080 DCI
3654 x 2664 Academy
3996 x 2160 DCI 1.85
4096 2160 DCi

So it appears it will not work with timeline resolutions that have the same aspect ratio of 16:9.
But it can work when the timeline resolution has a different aspect ratio.
I did not test all values for timelines so it is possible others do not work.

Does it work on the Color page?

Does it work on the Color page?

Yes.
I just tried it on the edit page. It also works there (when using one of the above resolutions).

Just tried shooting something in 4K DCI (4096 x 2160).

Placed on 4096 x 2160 timeline. Depth Map works.
Placed on 1998 x 1080 timeline. Depth Map works.

Placed on 3840 x 2160 timeline. Depth Map DOES NOT work.
Placed on 1920 x 1080 timeline. Depth Map DOES NOT work.

So it seems to be an issue with 16:9 aspect ratio timelines.

Just to make sure it's not something footage dependent, does DM work with https://coverr.co/videos/black-dog-play ... DcRZ6rUr0I in 1080p/2160p (16:9) ?

Just to make sure it's not something footage dependent

I shot a bunch of new clips (both BRAW and Prores) on a BMPCC4K.
Any clip which was 16:9 (HD and UHD) would not work on a timeline with the same aspect ratio but would work on timelines with other aspect ratios (ex. 4k DCI).
Any clip which was not 16:9 (like 4k DCI) would work on a timeline of the same aspect ratio but would not work on on a timeline with a 16:9 aspect ratio.
I think this rules out that it is related to the footage.

But I did download it.

It does NOT work on either HD or UHD timelines.

I does work on:
1998 x1080 DCI Flat 1.85
2048 x 1080 DCI
2048 x 1556 Full Aperture
3996 x 2160 DCI Flat 1.85
4096 x 2160 DCI
4096 x 3112 Full Aperture

No problem here with the "Black Dog Playing in the Garden" (HD) in a HD timeline.

I've just tried Depth Map with some HD 1920x1080 clips and it is working fine.

I've just tried Depth Map with some HD 1920x1080 clips and it is working fine.

And just to verify the clips were on a 1920 x 1080 timeline?

Yes.

[quote="So it seems to be an issue with 16:9 aspect ratio timelines.[/quote]
i think same.
i set 8K DCI resolution in project and works ok. It is not problem GPU or RAM. Something wrong in 16:9 resolution algorithm for Depth Map.

And it's a yes from me too.

That is interesting.
I tried installing the same driver version you have and it did not resolve the issue.
I wonder if it is a configuration issue as your system differs from mine in almost every way.

Just downloaded Beta 5.
Quick test and issue still exists.

Here's an exaggerated effect I have just done in the Color page using the Depth Map, so it is working here. Clip is 1920x1080.

I didn't see anything where he addresses the issue I have described above.

thanks, everyone for this thread. I am also experiencing the same issues and i have tried changing my timeline resolution to the suggested ones on here. and the depth map works perfectly fine. but it doesn't work on the 16:9 stuff

System specs:
LENOVO LEGION Y740
intel core i7-9750H
16gbs of ram
512GB of storage
Geforce gtx1660ti - 6GB of VRAM

Hmm, 1920x1080 is 16:9 according to my school math.

Hi all

18.0b6 should fix this issue. Please try it and let us know if you have other feedback.

Thanks for the reports

I downloaded Beta 6 and just tested it.

Unfortunately the original issue still exists.
Not only that, it now no longer works on those scenarios where it used to work.
So I now get Total Black result regardless of timeline resolution.

Earl, it's very hard to think of what would cause your problem. Depth Map is working perfectly in 18.0b6 on my system. This is on the Edit page.

Hi Earl

Thanks for the feedback. We would like a few bits of information from you.
• A summary of your hardware, OS and driver setup - it would help if you can aggregate it from your previous posts so it is in context.
• Description of project setup - media codecs, proxy parameters, performance mode etc.
• A simple set of steps to reproduce the issue - even a simplified list like "Untitled project, Add this clip to timeline, make sure these are the settings, switch to color page, drag in depth map, use these settings, turn on" would help determine where our tests differ from your scenario.
• Steps you may have tried as workarounds - GPU driver updates, toggling performance mode, transcoding clip.

Given the issue still persists, can you generate a link with the following:
• Diagnostic logs generated with 18.0b6 after a Depth Map all-black test
• An exported project DRP - so we can take a look at project and timeline settings in more detail.
• if this issue is specific to certain media files, a copy of the media clip.

Thanks again
Shrinivas

I was contacted through PM.
I have replied there.

i think problem only with our videocard GTX 1660 TI.
Now i have 18b6 and problem still there and even worse. (now works only with almost square aspect ratio )
i have 18b5 as Copy folder with same projects, folders and settings:
c:\Program Files\Blackmagic Design\DaVinci Resolve\ -default folder 18.b6 -do NOT works with 16:9 aspect ratio.
c:\Program Files\Blackmagic Design\DaVinci Resolve 18b5\ -copy of previous version (copy-paste) works fine with NOT 16:9 aspect ratio.
c:\Program Files\Blackmagic Design\DaVinci Resolve 18b6\ -copy of current version (copy-paste)? do NOT works with 16:9 aspect ratio.

why i do copy?
default path works but present some freezes -*.265 files very often plays with lags and less fps then in file or project.
If i start Resolve from Copy- works fine, even with NR until 3-4 steps with same fps without any freezes
Yes it strange ( i did it always from 17.* versions) reinstalling or full delete with reestr and more can't helped yet

i think problem only with our videocard GTX 1660 TI.

This may be (and specifically the laptop version).
I believe someone is working on this. I was contacted through a message and I supplied some information.
Since they posted Beta 6 should have fixed it, and it did change the outcome (unfortunately for the worse), I suspect they have an idea of the issue and where in the code it is located.
I have not heard back yet, but hopefully the next release will have a better result.

Downloaded new version (18.0)
Problem appears to still exist as it did in Beta 6 (not working with any timeline resolution).

I have the same card (Nvidia GTX1660TI) on a laptop and I’m really disappointed with this issue. I believed it would be solved by now. I’m using the depth map function (which for me is really useful) on a couple of projects and am still using 18 beta 5 to be able to work in at least DCI formats. Thanks for keeping us informed. I sure hope Blackmagic is working on this.

Perhaps previous commenters (aquadrat, Fireniko, mfjae01) could verify whether they are seeing the same thing as I am seeing? I don't think this is specific to my situation, but it might help if others confirm it is a more common problem.

I have the exact same issue going on.

Ryzen 5 2600
GeForce GTX 1660 Super
32GB RAM

I'm noticing a trend of people with 16 series cards not being able to generate a depth map, both in the Resolve discord server, and in this forum. I hope Blackmagic finds a fix to this.

I installed Resolve 18 today.
In the previous beta version 18.0B6, DepthMap worked in the following timeline resolution: 1998x1080 DCI Flat 1.85. Not in the timeline resolution 1920x1080 (16:9)
I opened the same project with the same settings in the latest version of Resolve 18.
Depth Map no longer works with any timeline resolution at all.
I have reinstalled the Beta version 18.0B6.
It is a pity that with the new version Depth Map no longer works at all.

(HP Omen I7 - 64 Gb Ram + Nvidia GT1600 Ti - 6 Gb)

A short update as requested:
The "final" Version shows the same result as the previous "beta" versions.

This possibly could be a particular model of GPU problem.
I have no problem using the Depth Map on my system. Pics show a rough and extreme use of the Depth Map in the Edit page. Sky was altered in the Color page. Video file is 1920x1080 50fps h264. Computer specs in my signature below.

It does appear each person seeing this issue has some version of a 1660 graphics card

I have the same problem with at 3080TI (Gigabyte-NVIDIA) GPU
It is also very stop/start trying to render it.

EDIT:- Also see the thread on missing media that "reappears" when you change the cache settings
Changing render cache format from DNxHR HQX to DNxHR 444 - HDR.
I don't know if the two defects are rleated or not

Thank you. This adds new information to the extent of the problem.

Downloaded and installed DaVinci Resolve 18.0.1.
This is not listed as an issue addressed with the update.
Ran test and it still exists as an issue.

Can confirm, problem still exists in latest update (18.0.1). Seems as if it's not related to the Media Offline issue.

just did update to 18.0.1 (default path over beta) + did update Nvidia Driver to 516.93
Depth map do NOT working (Edit + effect/ Fusion+ node/ Color + node) with any Resolution in project settings.

i have copies of Program folders for old versions Resolve. I opened last project in each of it. Depth map WORKS only in 18 beta 5 with any project resolutions not equal 16:9.

i can to show my old (for beta version) video to understanding our issue

Thanks for adding this video showing the issue.
I supplied a short video clip (and other files) to someone at BM support who contacted me.
Your video has much more detail and clearly shows the issue.
I am hoping this is getting proper attention as it seems to affect quite a few users.
Perhaps the next version will see a fix.

Hello everyone.
Same problem here.
Nvidia GTX 1160 Super.
I think it's windows 11 or the nvidia driver for windows 11.
I roll back to Windows 10 and everything work.
