AVCD for 29.97p 8bit 4:2:0 is set at 24mbps and uses a HIGH 4.0 H.264 profile.

XAVC for 29.97p 8bit 4:2:0 is set at 50mbps and uses a HIGH 5.1 H.264 profile.

So yes. XAVC will be WAY more durable in post than AVCHD.

Off the top of my head, I don't remember if they both use the CABC tool set for entropy or not.

But the bottom line encoding and decoding are two different things. But if Sony encoded XAVC in a way that was outside of the MPEG h.264 bible...than nothing would be able to play the files. Vegas, media player, VLC...whatever player you have that supports h.264 and MPEG libraries would not work.

Again...XAVC is fully compliant STANDARD H.264 and nothing "new" to H.264 that was developed so many years ago.

(SONY builds awesome encoder chips for VBR though. AND I believe they have some encoding patents too.)

It should be important to note that H.264 acts on a logarithmic curve (not linear) when it comes to how much you gain from increasing the bit rate. The higher you

So you will see a very noticeable increase in quality when double the bit rate from 12mbps to 24mbps. But when you double the bit rate from 24mbps to 50mbps, you won't see the same amount of quality increase.

That being said, from everything I've heard about XAVC it is an excellent coded. Just don't expect it to be twice as good as AVCHD (unless Sony really did some crazy magic).

I've been shooting 4K at 60p, 4:2:2 10 bit, 600 Mbps. It rocks.

What camera, Mark?

I bet it does rock! I'm jealous and have "CODEC envy".

Cant wait to get my hands on that FS7.

Just spotted this video - not sure if it's been posted before on this thread.

PXW-Z100. The sensor is the limitation on this camera (noisey, Neat Video will fix it, but still...), the codec is great.

New C100 MkII video - in French and Japanese. Shows, amongst other things, the face tracking feature plus LCD, EVF positions etc.
