What happened to Intel's quicksync problem recently?

Looking at some old information, I noticed that the Adobe Premiere 2025 version is facing an Intel QuickSync problem. I think it's been 4 or 5 months, how is this problem being solved now?

Please tell me the nearest alternative between the two.

1. Better way (no use of Intel QuickSync)
2. Intel Quick Sync is still good for certain conditions

And some users said that with the Nvidia 5000 series, there could be a world where you don't have to use Intel's CPUs. I wonder if this information is true.

No clue what you're referring to. Do you mean use of the iGPU?

Actually, beginning with version 25.1, Adobe has changed the GPU priority for H.264 decoding. In 25.0 and earlier, the priority was Intel > Nvidia > AMD. Since 25.1, the priority is now Nvidia > AMD > Intel.

The above is only for H.264 decoding. For H.265 (HEVC), the priority is still Intel > Nvidia > AMD.

I wanted to know this. Thank you.

Hey, you're right, this is a known issue. The best approach is still using Intel Quick Sync.

Here's the quick fix:

The problem is that since Premiere Pro 25.1, Adobe changed the H.264 decoding priority to Nvidia/AMD > Intel. This makes Premiere use your main GPU for decoding, ignoring the more efficient Quick Sync.

The Solution:

1. Go to Edit > Preferences > Media.

2. Under H264/HEVC hardware accelerated decoding, uncheck your main GPU (Nvidia/AMD) and leave only the "Intel" box checked.

3. Restart Premiere.

This forces Premiere to use Quick Sync for decoding, freeing up your main GPU for effects and rendering, which results in much better performance.

Regarding the Nvidia 5000 series: Even with a powerful GPU, using Quick Sync is smart because it offloads the decoding work, allowing 100% of your main GPU's power to be used for rendering and effects. It's about efficiency.

Hope this helps!

In theory, that's a good option. Unfortunately, when it comes to 10-bit 4:2:2 H.264, Intel's latest Quick Sync hardware decoder still does not support it at all. Instead, all decoding of that material goes directly to the CPU in software-only mode. Only the NVDEC in the Blackwell-architecture GPUs supports 10-bit 4:2:2 H.264 decoding. All other hardware decoders, including all versions of Quick Sync, are limited to 8-bit 4:2:0 support for H.264.
