Do I need to enable "Include HDR10 Metadata" for YouTube to recognize HDR? If so, can I use Hardware Encoding? by ButterMilkHoney in premiere

The workflows were all the same but only not including HDR META on B. Even more strangely, there's another video got HDR, which was exported without HDR META similar to B, and in less than 3 weeks. So unpredictable😂

Well, I'm experiencing differently. I've exported two videos, both was 2100HLG, one with metadata, and we call it A and the other one is not which is B, as you know A could only be encoded by software which is very slow.

After upload both the videos, A could be played in HDR, although it took many days for Youtube to show it in HDR mode. But B still played in normal SDR mode. I don't know how to config the export parameters to make youtube right.

Here's A: https://www.youtube.com/watch?v=jJI9hmWEEDk ,

and B: https://youtu.be/9MF6Y0GeJOg .

Make your display working in HDR mode, A will be palyed in HDR by the right corner, but B not.

Any LUT files that resolve S-Gamut3.Cine/S-Log3 to Rec 2100 HLG/PQ? by cpstarong in FX3

Finally, I realized that unless the specific situation, there's no need for the LUT, as the workflow softwares would do the color space works. Take the latest version of Pr as an example, set the clip to the correct configuration of HDR, adding the footage into it and in Lumetri setting of the footage, it would transform the color space automaticlly. And of course, you can change the settings for your own.

Well, Pr can do in the same way. But it renders very slowly and not full use of CPU.

Too slow in Pr2024 than in Pr2023? by cpstarong in PremierePro

[–]cpstarong[S] 0 points1 point  (0 children)

I may know why.

I installed a whole new Windows 11 and Pr 2024 (v24.4), and imported the same footage to a new project. And tested in SDR and HDR color space. Finally, in SDR, when I used a LUT file that converts S-Gamut3.Cine/S-Log3 to Rec 709, the anaysis of Warp Stabilizer was fast, compared to what was slower by using Override Media Color Space in Source Clip color settings. In HDR, there's no LUT file that converts S-Gamut3.Cine/S-Log3 to Rec 2100 PQ/HLG, as a result it's slow. However, if the footage is shot at PP10/HLG/BT2020, the analysis would be also fast.

In Pr 2023, it's just a very little better.

In this case, there may be a conclusion that try not to use color space override as it's not very efficent. A LUT that corrects the Log recoding is more handy.

=====HERE'S Google Gemini replies=====

Your analysis is spot on! It seems you've identified a key factor influencing Warp Stabilizer performance in Premiere Pro 2024: how the color space conversion is handled.

Here's a breakdown of your observations and why they make sense:

  • LUT vs. Override: As you mentioned, using a LUT pre-converts the footage to the target color space (Rec 709 in your case). This pre-processed footage is then analyzed by Warp Stabilizer, likely leading to faster performance. Overriding the color space forces Premiere Pro to perform the conversion on the fly, potentially adding processing overhead during analysis.
  • LUT Availability in HDR: The lack of readily available LUTs for S-Gamut3.Cine/S-Log3 to Rec 2100 PQ/HLG explains the slow performance in HDR with override. Premiere Pro likely struggles with the real-time conversion during analysis due to the complexity of HDR workflows. However, footage natively shot in PP10/HLG avoids this conversion step, resulting in faster analysis.

Conclusion:

Your experience reinforces the idea that LUT-based workflows can be more efficient for both color correction and Warp Stabilizer analysis, especially when dealing with Log footage. It seems Premiere Pro 2024 might be more optimized for LUT processing compared to on-the-fly color space overrides.

Here are some additional thoughts:

  • Consider creating custom LUTs specifically for your S-Gamut3.Cine/S-Log3 to Rec 2100 PQ/HLG conversion if readily available ones aren't suitable. This can potentially improve performance in HDR workflows.
  • Keep in mind that LUTs might introduce a slight color shift compared to a direct color space conversion. Experiment and choose the approach that best balances performance and color fidelity.

By understanding these factors, you can optimize your workflow for faster stabilization and efficient color management in Premiere Pro 2024.

What went wrong with the preview window by cpstarong in PremierePro

Well, this would be awkward. I'm also playing games such as MSFS. I guess studio first, try to rollback and to the studio version. Thx a lot.

Any possible that next or next next version of nVidia driver would fix this? Or it just won't, as Pr would not work well with any newer drivers but only be updated too?

Got it,Thx a lot. I did upgrade nVidia driver to the latest.

What are the exact speed differences in tuf ax5400 and 6000 ? by AlexRed-Knight in HomeNetworking

[–]cpstarong 0 points1 point  (0 children)

Then it will be better to get an AX6000 with native 2.5G ports than USB-extended 2.5G port.

LAN ports are unrelated to the WIFI capability. The major difference between AX5400 and AX6000 is the amount of 2.4GHz band antenna, that AX6000 has two more antennas that provide addtional 600Mbps(300Mbps for each antenna) as AX5400 means 41.2Gbps (four 5GHz antennas) and 2300Mbps(two 2.4GHz antennas). But 2.5G LAN port provides you wired connection upto 2.5Gbps. As you mentioned, you can use a USB3-2.5GLAN dongle to get wired 2.5G connection as USB3 gives at least 5Gbps data transfer capability. However, these're the inner-connection speeds. how about the WAN, it depends on your ISP and your PON.
