SVT-AV1 V4 and Opus V1.6.1 - lameuser - 06.02.2026

Hi Selur !

Sorry for my poor english ,its not my native language.
Can you please include the new SVT-AV1 V4 with advanced settings in its tab and Opus V1.61. in the next Hybrid release ?


RE: SVT-AV1 V4 and Opus V1.6.1 - Selur - 06.02.2026

the dev should include newer files.
What settings are missing?


RE: SVT-AV1 V4 and Opus V1.6.1 - lameuser - 06.02.2026

I dont want to post the parameterlist here. You know ,just type    SvtAv1EncApp.exe --help.
There are many of them.
For example ,V4 have : tune mode 4 , --qp-scale-compress-strength ,etc. Yes ,i know i can add parameters manually ,but using a GUI is better. If you plan to add these items ,just take your time ! Smile

Dev. version : Thanks for the info !


RE: SVT-AV1 V4 and Opus V1.6.1 - Selur - 06.02.2026

It would help If you posted the parameters you think should be added, otherwise I might not add them, since I assume that nobody would use them.
I probably will not have time to look at it this weekend, but I'll look at it next week and report back.

Cu Selur
