Shake 4.1 & Prores Hq Codec

[user_deleted]

Hello there,

I'm trying to use the new Prores codecs from FCS2 with Shake, and I found no documentation about difference between prores and prores HQ. So I guessed HQ means 10bit but when rendering 32bit tree in Shake to prores HQ, the output QT is then seen by Shake as an 8bit file.

Is it coming from Shake that doesn't know prores HQ is a 10bit file, only when reading it ?
Or from Shake that believes Prores HQ is an 8bit format when writing it, and so dropping down from 32 to 8bit before compressing to prores HQ ?

How can I be sure that my file is really 10bit ?

After Effect CS3 beta sees also it as an 8bit file, and I found no way in FCP6 to get bit depth info on the file...

Thanx for any help

David

The difference between HQ and the other is the data rate.
HQ is 220 Mbps and the other is 145 Mbps.

If it's showing as 8-bit in Shake that's probably because it is I'm guessing.

Here's a link to the white paper on ProRes.

Well...The white paper you're talking about mentions Prores is 8 AND 10bits.

So when Shake rendering a 32bit pipeline to a Quicktime output node, with ProresHQ selected, I guess the 10bit option should be used...if a 32bit feed is not enough for Prores to switch to 10bit, how can I force it to record 10 ?

Thx again

You can't, this is probably just an issue with Shake being older then the codec or the fact that Shake uses a really old version of the quicktime sdk. Render out to an intermediate format and then convert it to Prores.

This makes sense!

Thank you!

You can work in ProRes HQ in Shake, but you'll need to use a Bytes node to set it to 8bit when you output,
regardless of whether you're outputing to ProRes or ProRes HQ. Not a perfect world, but a pretty nice one.
