Thank you, John!
I'm trying those configurations. Let you know the results once the BD is ready.

With this parameters, encoding just the first video (around 60min long) takes more than 8 hours. Even I have GPU encoding enabled, when I start the process a message appears saying GPU acceleration was disabled and suggest to update graphics driver. With the 1080p24 configuration, each video didn't take more than 20 minutes for encoding.

Is there anything I can do to improve the encoding time?

Thank you!

Hi

. . . . 60min long takes more than 8 hours . . . GPU encoding enabled . . . GPU acceleration was disabled . . . .

This would suggest the CPU is doing all the encoding.

What is the specification of your computer system including Windows version and program version, see this topic for what is required and please quote processor and graphics card make/model in full, and also what monitor/screen resolution(s) you are working with if this is a laptop.

I would suggest you put this information in your profile signature so we do not have to keep asking for it.

Are the graphics card/integrated GPU drivers up to date?

A screenshot of the Program settings, Device options tab will help.

. . . . 3 mp4 videos . . . .

Are these the only media on the timeline, or are there images as well, have any effects been used ?

Hi John,

Let me describe my computer specifications:

CPU: Intel i7-2600K @ 3.40Ghz
RAM: 32GB DDR-3
GPU: NVIDIA GeForce GTX 1650 Super (4GB) (PCI-e card)
Monitor resolution: 1920x1080 @ 60Hz
OS: Windows 10 x64 22H2

NVIDIA drivers are up to date: v581.15 (Aug 28th, 2025)

The MP4 videos are just added to the timeline, each one in a different tab. And I only added chapter tags. No filters/fx/transforms applied to videos.

About the "Program settings, Device options tab", I have Video Deluxe with spanish language. I don't find any "Device" (Dispositivos) tab but I think the one you are asking might be this one:

Thank you!

Hallo @calamar,

When burning to a Blu-ray, the GPU acceleration of my NVIDIA card is also disabled. As far as I know, it's not supported when burning H.264.

If I switch to the integrated Intel® UHD Graphics 630, the GPU acceleration isn't disabled.

Perhaps @johnebaker can explain this.

Now for the explanation: why encoding a film of approximately 60 minutes takes more than 8 hours. The Intel i7-2600K @ 3.40 GHz processor from January 2011 has to do a lot of processing. This is also why burning takes quite a while. My advice is to upgrade your computer. These are the minimum system requirements for VDL2025/2026. See: Video deluxe Technical Specifications — An Overview

Best wishes,

This post explains why external GPU encoding on longer occurs on Interlaced Bluray projects:

https://www.magix.info/us/forum/vpx15-no-hardware-encoding-during-bd-burning--1333831/?page=2#ca1912059

As far as "minimum specs: goes, really there aren't any. The program will run on very little. But if you want a quick encode, you want hardware acceleration (apart from Bluray Interlaced) and/or you want a snappy, responsive timeline, then you need a modern, fast computer (actually, better than the specs published by Magix). The slower your system is, and particularly the CPU (if your graphics card won't hardware accelerate your processes) then the longer things will take. For example, heres' the i7-2600K verses my i7-13700K which I bought in 2023:

This is the website: very handy for comparing CPUs.

Mine would probably encode your Bluray project in just over an hour; in addition, for Bluray Interlaced encoding, the IGPU will be used, speeding things up even more.

Hello @AAProds,
Thank👍 you for this information/explanation. It's very interesting to delve into this further.

Best wishes!

Thanks for the information and details.

I still don't completely understand why BD discs with 1080p24 encoding takes about 20 minutes and GPU encoding is enabled, while 1080i25 takes 8 hours and GPU encoding is disabled. Is it soo different to code progressive than interlaced material? Why hardware accel. is enabled for 1080p and disabled for 1080i if the codec used is the same? (Well, in fact seems it's not disabled for 1080i as VideoDeluxe seems to support it. But when starting the process, I see that message of hardware accel. disabled due to drivers outdated).

Meanwhile, I tried other 3rd party Media Creation software that basically input the video files, create a disc menu, and it encodes and burns into a BD. And the process didn't take more than 1 hour and the result was with no jittering issues in the video.

So, I'm not completely sure if the problem is really my CPU when other apps doing "the same" (quoted) work doesn't take a whole day to create a BD that is properly readable. Additionally, I don't have any issue when creating DVD media with VideoDeluxe. Encoding and burning doesn't take more than 1 hour and the disc created is perfectly readable.

Ok, I dig a bit more on that link @AAProds shared and did a bit of search on internet and seems that basically GTX 1650 Super does not support interlaced encoding any more.

So, my question here is: if there's a 1080p24 setting chooseable for creating BD media, would it be possible to have a 1080p25 settings on that dialogue window. At lease GPU accel. will be used and I wouldn't have that jittering effect on my videos.

Thank you!

@calamar, @Bol, @AAProds

Hi

. . . . Why hardware accel. is enabled for 1080p and disabled for 1080i if the coded used is the same . . . .

This is due to Nvidia removing the capability of encoding interlaced video, irrespective of whether the source video is progressive or interlaced, using the independent NVENC video encoding 'module'. The capability was removed starting with the Turing and later families of GPU's.

You will find that your GTX 1650 Super may be being used for some effects processing, this will be seen in the 3D pane of Task manager, Performance page when you select the GPU for monitoring.

The Intel i7-2600K has a HD 3000 integrated GPU, however this cannot be used for encoding as it does not support DirectX 12.

If you are considering a new computer then I would suggest an Intel processor with integrated GPU and a Nvidia RTX 2000 series or better graphics card, see my signature for my computer and laptop specs, both handle 4K UHD 50 fps 10 bit (HDR) source videos well. Export/rendering times vary depending on resolution being exported to, typically I see anywhere between 1/2 to 3x the run time if exporting to t4K source to 4K export. Exporting to a lower resolution eg 4K down to FullHD (1920x1080) is usually quicker.

This combination gives you the best of both worlds and I see both GPU's in use when rendering video depending on effects etc used in the project.

I normally use the RTX 2060 for editing and file export, of none Blu-ray file formats.

For BD discs I switch to the Intel UHD 630, which does accelerate processing of 1080i video, when either burning a disc from within the program, or exporting for use in DVD Architect for more complex BD discs.

@calamar

But when starting the process, I see that message of hardware accel. disabled due to drivers outdated

Yes, that message is a furphy. We all get it when we try Interlaced bluray encoding.

 if there's a 1080p24 setting chooseable for creating BD media, would it be possible to have a 1080p25 settings on that dialogue window.

Short answer: I doubt it. Have a look at the Bluray spec: 1920x1080 25P is only for UltraHD Bluray using HEVC. I suspect that when Bluray authoring was incorporated into Magix, UltraHD probably didn't exist (or was deemed too hard, not needed...insert reason [here]).

https://en.wikipedia.org/wiki/Blu-ray

Ok, so... upgrading my computer is the only solution to get higher speed in the encoding process 😅. I will consider your computer specs as a reference to look for my new equipment.

Thank you for all the information you provided and your support with my doubts (and your patience!).

@AAProds

Hi Al

. . . . 1920x1080 25P is only for UltraHD Bluray using HEVC . . . .

Do you mean 4K UHD 3840 x 2160, 1920 x 1080 is more commonly referred to as 'FullHD' and in some instances, IMHO incorrectly, as HD?

There are no 4K UHD Blu-ray discs nor compatible writers available, the format is strictly commercial only.

John, just repeating what the wiki says regarding 1920x1080P 25. Whoever put in that part probably used the wrong words. The point remains that 1920x1080P 25 isn't a standard Bluray format and so was not added by Magix when the feature was added, and hence is not in the encoding options.
