Premiere Pro 25.1 - iGPU stopped decoding my footage

[AndrewTheGreat]

Ok, just updated to v 25.1 opened my projects in progress to find out that none of them uses my iGPU to decode.

Went on checking it with different formats that are decoded (h264 8-bit 4:2:0, h265 8-bit 4:2:0, h265 10-bit 4:2:0, h265 10-bit 4:2:2) by the iGPU - all of them show 0% load.

What is going on, guys? Why is it "new version - new bugs" thing every time? My CPU immediately started being loaded more, like by 60% all the time, even though my GPU does the decoding, whereas on the previous versions the average CPU load was 20-30% with the iGPU doing all the decoding job.

Yes, I tried reinstalling both Premiere Pro (as well as resetting its cache, preferences and plugins via the start+shift menu) and all the drivers. 

Steps to reproduce? Open a project or create one, import a knowingly decoded video, put it on your timeline, press Play. Watch the the Windows Task manager - Performance graphs.

Hi all, 

We've identified the source of the problem and have a fix for it. I'll post another update here when the fix is in our public beta. @AndrewTheGreat we'll be very excited to get your feedback on the fix!

Thanks,

Thanks y'all for the clarification on my prior post.

Good day. Since we're talking about problems with other languages, there's been a problem with finding effects in Cyrillic for a long time. If you type the effect name in lowercase letters, it won't be found, but if you start typing it with a capital letter (just like it's written in the list of effects), it will be found. There are no problems with effect names in Latin - you can type them with either a capital or lowercase letter. It would be great to fix this.

Hi @AndrewTheGreat 

I'm a bit late on this as only just returned home. I see the problem has already been identified which is good.

For the sake of checking I did try it out and results attached.

iGPU happily decoding at about 49%. 13900K CPU at 20%. NVidia 4080 Super at 59%.

Intel iGPU driver on latest one, 32.0.101.6987.

NVidia Driver 576.80

Well, it might be a little stupid question,

Not only the rendering (Export), but also the timeline preview is affected by that, right?

If you use a premier version of 25.1 or higher, except in special circumstances
Intel QuickSync Does Not Work Properly Under Normal Conditions

Can I see this information as something I need to know?

[AndrewTheGreat]

Rendering is the last thing you should consider. It normally is as fast as your system can provide. The problem we are dealing with here mainly affects the playback speed and smoothness.

Thank you for your kind information
Thanks to you, I think my thoughts are organized well !

Hi All,

Apologies for the inconvenience caused. We have addressed a major issue discussed in this post, where HEVC files in non-English folder paths may not be decoded via Hardware.

• The fix is now available in the latest beta versions of Premiere Pro (25.6.35 and later), AME, and AE, and is expected to be included in the next official updates of these apps.

We truly appreciate your support and collaboration in investigating this issue. While beta builds are not recommended for production, they install separately from release versions and can be used for testing the fix. Please let us know your feedback after testing.

Thank you for your patience and continued support.

Best regards,
Mayjain
