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 !
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.

Found some time and uploaded a new dev which comes with new tool binaries and adds ui elements for:
--tf-strength Adjust temporal filtering strength, default is 3 [0-4]
--luminance-qp-bias Adjusts a frame's QP based on its average luma value, default is 0 [0-100]
--sharpness Bias towards decreased/increased sharpness, default is 0 [-7 to 7]
--enable-variance-boost Enable Variance Boost, default is 0 [0-1]
--variance-boost-curve Curve for Variance Boost, default is 0 [0-2]
--qp-scale-compress-strength QP scale compress strength, default is 0 [0-3]
--ac-bias Strength of AC bias in rate distortion, default is 0.0 [0.0-8.0]Cu Selur

Maybe more to come.
Btw. the encoding process doesnt work on my side. It starts and after a short period of time finishes with a very small file. (~1xxx bytes long)
RE: SVT-AV1 V4 and Opus V1.6.1 - Selur - 09.02.2026
Typo, instead of 'curce' it should be 'curve'
Uploaded a new dev which should fix that.
