10 bit Encoding

[Boltron]

I would like to evaluate 10 bit encoding of my movies. I am using the 10 bit x264 encoder from http://x264.nl. I want to convert the h264 video files extracted from my Blurays.

My question is what are the correct x264 settings to convert 8 bit to 10 bit? I have looked around and can only find settings for full 2 pass Bluray authoring which I did try but it took an incredibly long time. As my h264 files are from Bluray already, I think the process should be much more basic than a full authoring run.

Any advice or guidance will be most welcome.

If you're using a 10-bit x264 then the conversion to 10-bit is as easy as: x264 INPUT -o OUTPUT

If you want to do compressed-domain transcoding then you are SOL, there is no software for that.

Doh! x264 in out. Now, why didn't I think of that LOL.

Thank you.

You may want to set some options though, like change CRF from the default value of 23, set a speed preset and a tuning:

x264 --crf 20 --preset slow --tune film INPUT -o OUTPUT

Perfect, thanks.
