Hi @kirithika7, is there a way to use for example CRF=20 encoding, but also limit the maximum bitrate? If yes, could you add more usage example in the user guide? Thx.

Hi @thjr,

In order to merge the CRF implementation, we need to make sure that there isn't PSNR/SSIM BDRate regression. But due to the PSNR/SSIM BDRate drop issue caused by another PR #348 , we planed to fix it at first, then go ahead to merge this CRF PR. Thanks!

I'm pretty sure development on svt-hevc is dead.
