 Replying to [comment:474 Kamedo2]:

 32kbps, the native encoder seems to be stable.

 It's in the pipeline.

 Just doing some regression ABX testing, since the objective (PSNR) A/B
 script pointed out some seemingly significant regressions (until now I
 couldn't confirm anyone with ABX but I'm not done testing yet)
