Hi there,

When I try to export a file as H265 I can not find it for some reason.
In many tutorials I see H265 is avaiable when I export as Quicktime, but in my dropdown menu H265 is not available. See my screenshot.
Why is H265 not there on my system?
I am using Resolve version 19.01 Build 12

As you are running Studio 19.XX it should be there. This is what I see in 19.1 Studio on Windows.

Charles Bennett, as you can see on my screenshot I do have version 19.1
But you also can see I don't have H265 in my menu for some reason....
Not in the Quicktime format, not in MP4, or any other format.
No H265 to be found on my system.
I realy don't understand why....

You sure you’re running the studio version?

Yes Steve, 100% sure, the latest version I installed a bout 10 days ago.

Leave encoder set to Auto. Switch to MP4. What are your options?

Posted: **Mon Nov 25, 2024 9:44 pm**

There should be a dropdown choice below H.264 that includes H.265 as an option:

What i've noticed is that there is no software H.265 encode, choosing native does a lower bitrate GPU encode than choosing Nvidia. If that is true for everyone then the reason you may not have a H.265 option is because Resolve can't see your GPU encoder for some reason.

@Thijo van Beek: What platform are you on? Mac, Windows or Linux? What OS are you using? What GPU are you using?

A Resolve diagnostics log could be quite helpful. Generate that from the Resolve Help menu.

That might be the problem as I am working on a pretty old laptop.
For the Encoder I can select AUTO or NATIVE, no more then that.

I am on a Windows laptop, Windows 10. The age of yhis laptop might be the problem I'm afraid.

If Resolve 19 is running it can't be that old can it?

IIRC the current requirement is 1060 generation or newer. That should handle 265 shouldn't it?

Not that old, right. I was just wondering... Do I have to download a codec myself to get H265 maybe?
Sounds stupid maybe, but I'm an old man and happy to play with resolve!

Posted: **Tue Nov 26, 2024 11:30 am**

Do you mean the Microsoft codec? For studio I don't think you should. The hardware on the GPU handles everything. The Microsoft file might help for software rendering I guess.

But I've had the file installed from when it was free ten years ago.

Nick, I know almost nothing about codecs. The Microsoft codes are for mediaplayer as far as I can see.
I never use mediaplayer, only VLC player.
I thought maybe I need another codec. So my problem why I can not export in H265 is still not solved.
But I am happy all of you at least try!

Bob, I have no problem encoding h265 with either the Nvidia or Native encoders. Both produce exactly the same file sizes when all other settings stay the same.

Please provide a Resolve diagnostics log.

That's common.

When you select Auto, what are the options under MP4?

Sorry I respond so late, I had no idea how to find a diagnostics log but I've got it now.
I hope it helps you to find out what my problem is.
Oeps, the zipfile is too big to send it here!
Now what?

Posted: **Thu Nov 28, 2024 12:03 pm**

What about a cloud service?
See the FAQs.

Posted: **Thu Nov 28, 2024 12:06 pm**

My software is up to date as you can see.
So that can't be the problem....
Should I use CUDA or OpenCL?
and 'GPU selection' on Auto or not?
Or keep it both on AUTO

Posted: **Thu Nov 28, 2024 12:37 pm**

Thijo, this is what you do with logs.

Charles Bennett wrote:Thijo, this is what you do with logs.

Hi Charles, thanks for your help. But this is too much for me I'm afraid.
When I do as you say, go to 'C:\Program Files\Blackmagic Design\DaVinci Resolve'
I see a file called CaptureLogs.bat.
I tried to open that but the I only got a black screen I didn not understand what to do with....
Me sooo stupid!

Basically the min requirements for Resolve are now Nvidia 1060 generation. I forget what this was called. Pascal?

If your GPU is new enough to run Resolve you should have all the hardware you need for 265.

I know Pascal! She's a very fine looking lady living just around the corner!

About my GPU: processing mode is on AUTO now. (CUDA)
When I deselect it I can also use OpenCL.
GPU selection is also on AUTO.
Deselected all I see is the NVIDIA card. The other one is greyed out, can't select that.
What setting for GPU should I use?
See screenshot.

Posted: **Thu Nov 28, 2024 7:57 pm**

You should be on Cuda but I don't know if your 860 supports 265.

Posted: **Thu Nov 28, 2024 9:18 pm**

That GTX 860M GPU with only 2GB of Vram just isn't powerful enough for Resolve 19. The very minimum Vram requirement is 4GB. It doesn't support full h265 decoding either.

Posted: **Thu Nov 28, 2024 11:34 pm**

Does it need to be H.265? Get a Mac mini base model then.
Or stick to 18.6.6 and use H.264.

Got it. Thanks.

I think if you correct that you will solve this. Your best option is to build a Windows desktop using a 12th Gen (or better) Intel CPU and the best nVidia RTX card you can afford with at least 12 GB of VRAM.

Good idea Uli. But: Kein geld leider.... (No money for that)

OK, clear. Nothing to do about it then. I don't have the money for the system you talk about.
I stick to H264 then.

Thanks everybody for al your thoughts!

You could export a less compressed video and decompress to h265 with free cpu encoder like shutter encoder or handbrake

Without a Resolve diagnostics log, it's hard to know for sure, but this is one of the Resolve 19.1.1 improvements. Perhaps it will allow H.265 on your hardware:

• Addressed H.265 encode issues on older NVIDIA graphics cards.

Could we get a list of "older" cards or something to narrow it down? To know which cards.
