[Doug Nichol] “How much of a visual difference is there between the normal ProRes 422 and the (HQ) version? I just realized my “Log and Transfer” from AVC-Intra was set to “normal” rather than “HQ””

Doug,

I just finished some extensive testing of ProRes and you are fine, In all of my testing I found that ALL software conversions to ProRes consistently played back better when the conversion was done in the same manner as you did.

Live Capture was better with ProResHQ, but I universally recommend the Standard ProRes for ALL software conversion – less horsepower, storage and bandwidth are needed.

I was wondering… why we don’t have the option of 422 10bit uncompressed ??? is it AVC-Intra a similar to Prores codec? so its not trans coding but re wrapping? For VFX and finishing I would prefer the Uncompressed instead of Prores for offline… its a matter of confidence… Noah any news from the Panasonic front, regarding AVC-Intra natively to FCP???

Looks like probably not from Apple. They seem pretty focused on the transcode workflow. However there are some third party apps that enable this, for example:

I don’t know if this is an Apple or Panasonic deal. Panasonic only gives out a decoder for AVC-I, not an encoder so there’s no way to edit AVC-I native as you can’t render to it. Also, when using Calibrated Software to read the native MXF files, AVC-Intra plays back very slow (less than real time). This is all a function of the codec, from what I understand, and not Quicktime. As of now, I don’t know if it could even be possible in FCP as the AVC-I codec is not real time.
