Topic: Yin Media Encoder
This is slightly off-topic but not so much because it allows easily re-encoding videos to 60fps, while also optionally upscaling them with very good quality (and applying a few other filters).
You can get x265 output with Opus audio if you want; or simply copy the source audio without re-encoding it.
I posted about this a while back, and now I just released v1.4 that has major improvements in every area.
This software also does a whole bunch of other cool stuff.
Note: the output would be further improved if SVP would support YV24 format, because now I'm downscaling from 16-bit YV24 to 8-bit YV12 in the middle of the processing before doubling the resolution again.
