25.1 slower h.264 exports

[10Eighteen Media]

Hi All,

Has anyone else noticed slower exports of H.264 files?  I edit mostly Sony HEVC 4K footage  and export 4K 50 mbit  H.264 files. A lot of the projects are 2-3 minutes in length and exports prior to 25.1 were usually under  5 minutes. Since 25.1  exports are taking 15-20 minutes!!!

I am on a windows Machine

AMD Ryzen 9 5950X 16-Core Processor 3.40 GHz

128 Gb Ram

Nvidia RTX 3070

NVMe Drives

I am not sure whats happening. Nothing on my end has changed.

Adobe, what am I missing?

Thanks

Darrell

Has there been a Windows update? It has been reported here that in the most recent one, on some PCs at least, the latest Win11 version actually turns off the iGPU under certain circumstances. Which definitely affects processing of long-GOP media.

And for that, the OP had to go into their BIOS settings and turn the iGPU back on, if I read correctly.

Would be interesting to hear a comparison of an earlier 25.x or the latest 24.x on your machine too.

That is Win11 24H2 ... and it's been raised with Microsoft also.

This thread has more information in later posts ...

Hi @10Eighteen Media ,

Thanks for highlighting your concern. We do not anticipate any export slowness in Premiere 25.1. Could you let us know if you’re experiencing similar behavior on other systems as well? If possible, please share some sample media/project which can help us reproduce this problem locally.

Thanks,
Mayjain

Hi Neil,

Thanks again for chiming in as always. I am still running windows 10. The problem for me just occurred from the 25 to 25.1 update with litterally no changes in anything.

Hi Mayjain,

I have another machine that is still running PP 24.6 so I will load the lastt coupe of projects up and try some export tests. As I stated to Neil. There were no cghanges to my system or to the media I am working with. One day running PP 25.0 everything exporting fast. Like I mentioned I do not have specific time pre 25.1 update because I did not have any problems but definately no lore then 5 minutes for a  2-3 minute final export. Timeline cosists of  Sony HEVC  H.265 footage exported to 50 Mbit 4K h.264 files. No heavy fx like noise redcuction or flicker free only a few warp stabilizer clips. Ran several exports this morning and they were all around 18 minutes for a 3:14 second timeline

I have another machine running 24.6 and I will do some tests.

I was able to go through my logs and find a project from PP25 that was still loaded on my computer. I then exported the same project again in PP25.1. The machine, operating system, location of media, location of export, all the same. No new hardware or software, only PP25.1 upgrade. The logs are posted below but the short answer is: When exported using PP 25 encoding time was 00:02:04 when expoted using PP25.1  the Encoding Time: 00:17:05 fiftenn minutes more. 

Adobe please help. Logs posted below

25.1 Software or Hardware Decoding?

[10Eighteen Media]

Hardware

[Alex367466572b5i]

Check it again... either the hardware decoding is not working or the CPU load is low.

[10Eighteen Media]

Just ran the same project and export through PP Beta 25.2 the the encoding time was 2:03 (log below) So PP25.0 PP Beta 25.2 encode the video in around 2 minutes. PP25.1 encodes the video in 17 minutes. All same machine, same hardware, same operating system. The only variable is the version of PP. Yes Hardware encoding is on and CPU is running normal before, during and after encoding.

DECODING... HW

[sotiris_tseles]

Same here, just updated to 25.1 and export is very slow, using mainly the CPU.

Adobe please fix your software, or redesign it from the ground up. My team and I are seriously considering switching to DaVinci at some point, and even watched tutorials about it.

[10Eighteen Media]

So I had to export out a 10:44 second video to H.264. Same type of source material,. Sent it to Media Encoder  1:04:15 yes you read that correctly over an hour!

So I then I exported the same video directly from PP25.1  and it encoded in just over 7 minutes. 

What is going on?

Adobe help me.

[Kevin-Monahan]

Hi @10Eighteen Media 

Have you tried a one-pass VBR preset?

I wonder if it could be related to this issue: https://community.adobe.com/t5/premiere-pro-discussions/premiere-pro-25-1-igpu-stopped-decoding-my-f....

I hope the team can assist you with this one shortly. Sorry for the problem.

Take Care,
Kevin

[10Eighteen Media]

Hi Kevin,

Thank you so much for jumping in. So I tried export VBR one pass and no change, still slow export through AME.  I read through the link you sent me regarding the decoding issues with windows 11 24H2. 

Firstly,I am still using windows 10 22H2.

Also my CPU is a Ryzen 9 5950X which has no IGPU

Both boxes in preferences are checked to use Hardware decoding and when playing back the Sony 10 bit 4:2:2 footage task manager clearly shows that the GPU is decoding the material.

I thin it is safe to say in my case the issue is not a windows issue. I have also found now that the issue only ocurs when I export the sony footage through AME.  If I export directly ffrom PP 25.1 I get the normal encoding times I am used to.

Thanks 

Darrell

[10Eighteen Media]

So just tried exporting through Media Encoder with the new PP25.2. It did not fix the slow encoding times I am having. Exported out a 16 minutes 1 track video with no effetcs and it took 43 minutes. Exported the same video out striaght from PP 13 minutes....so so frustrating....itas getting close to switching to Divinci

[Alex367466572b5i]

@10Eighteen Media Screenshot Task Manager & Export Settings AME?

[10Eighteen Media]

 

 

 

 

[Alex367466572b5i]

@10Eighteen Media Thank you. The CPU load is not visible in Premiere.

[10Eighteen Media]

 Thanks for taking a look

[Alex367466572b5i]

@10Eighteen Media In Adobe Media Encoder, uncheck the settings: Render at Maximum Depth & Use Maximum Render Quality.

[10Eighteen Media]

Zero difference. Like I mentioned in the original post. Nothing had changed in my workflow except the update of PP.  The update drastically slowed down my Media Excoder output for HEVC Sony footage.

[Alex367466572b5i]

@10Eighteen Media In one version of the program the checkboxes may be there, or if you remove them, then in other projects they will not be there either (this has been happening for many years).
Usually, the difference is in the CPU load, that's why I asked for screenshots, but yours is not that big.
Try disabling hardware decoding in Media Encoder, let the CPU decode.
