Final delivery: ProRes 422 (HQ) PC
Hi,
I am editing a bunch of commercials for broadcast and the client demands the final files in ProRes 422 (HQ).
I am natively editing the ProRes 4444 straight off the camera in Premiere Pro CS6 on a PC platform running Windows 8. Once I complete the edit I do the grading in Resolve 9 Light and render to QuickTime DNxHD 185 10 bit.
I then takes the rendered files into Premiere Pro and do the final touches and export to QuickTime DNxHD 185 10 bit again.
For final delivery I was thinking that I would just take all of the master files and load them onto a Mac and convert them to ProRes via MPEG Streamclip.
Would this be an optimal workflow without any quality loss?

It’s a good workflow, with only a little theoretical intergenerational loss and next to no visually perceptible loss. DNxHD, like ProRes, is designed to hold up over multiple generations.

You could export to uncompressed (I’ve lately switched from Blackmagic to AJA’s uncompressed 10-bit Quicktime codec) and then encode to ProRes using command line tools like FFMPEG or FFMBC.
I’ve made a program specifically to manage batching large amounts of files to ProRes (link in my sig) but it sounds like you can get away with just rendering out one or two deliverables via the command line.

Which Blackmagic codec were you using? I have been looking for info on the BMD 10-bit 4:4:4. I originally thought it was YCC, but the rendered output looks converted to RGB.

I’ve tested all of the available Quicktime options. I found there to be a color shift regardless of the program controlling the encoding that wasn’t related to the “quicktime gamma issue”. Off the top of my head, within quicktime you’re offered an 8-bit and 10-bit that I think are 4:2:2 YUV.
You have more options with the AVI exports BUT since I export a lot of RED footage, Redcine-X does not support exporting in AVI, so no point in using it. I suppose, since it comes to mind if I should process the RED files through AME to an AVI file and see if that shift still stands.
I’ve tried AVI dailies in Speedgrade, but it hits the oldschool AVI 4gig limit hard and will corrupt files.
