Export to ProRes on a PC
My problem is as follows:
I am editing and grading a commercial on a PC setup and the client wants a ProRes 4444 file as final delivery (old story).
I am editing a commercial in Premiere Pro CS6. The footage was shot on Alexa and the files are ProRes 4444 1920×1080 25p.
My workflow as follows:
1. Edit the commercial using native ProRes 4444 files in Premiere.
2. Export a MOV from Premiere using 1080p/25 DNxHD 444 10-bit.
3. Drop the MOV in a new Premiere timeline on a Mac.
4. Export final MOV as ProRes 4444.Would this be a good way to go about it? Obviously, the goal is to not lose any quality in the process.
Best,

Eric –
So what’s the workflow – export uncompressed from PPro and then use cinec to create the prores? I wish there was a simple plug-in so the export to prores could all happen within PPro, but then again nobody’s paying much attention to my wishes.

Yes export in an uncompressed format preferably QuickTime in this case and then run through Cinec encoder for Pro Res.

I use Avisyth, DebugModeFrameserver and FFMBC (I believe Cinec also uses FFMBC?). Encode from Premiere or Media Encoder to DebugModeFrameserver, pass the script to FFMBC and get a ProRes mov right away. No intermediate needed. It’s a little bit of a hassle at first but if you don’t need to batch encode from Premiere it’s not to bad once you’ve done it a few times to set it up.
Install AviSynth, DebugModeFrameServer and ffmpeg/ffmbc
Use DebugFrameServer (from Premiere/Media Encoder) to save an avi file like “temp.avi”.
In the same directory create a text file named “temp.avs” with this one line:DirectShowSource(“temp.avi”)
Use this avs file as a source for ffmbc
Open a CMD window in the directory and paste “Set Path” (Set path=C:Program FilesFFMBC_32bin;%path%) where your FFMBC is installed, then paste ffmbc script:
ffmbc -i temp.avs -threads 16 -vcodec prores -profile hq -pix_fmt yuv444p10 -acodec copy output.mov -
Yes, that’s an option.
But I could just take the uncompressed QuickTime file exported from Premiere Pro on my PC and run it through MPEG Streamclip for example on a mac to export a ProRes file.
Which was my initial question…

All the others have given you some excellent information – all of the tools leverage FFMPEG/FFMBC.
May I suggest my tool PRHelper in case you ever need to batch dailies? The interface is far more friendly for batch operation and I’m going to try and update it soon to handle single file operation using drag and drop (it’s a bit cumbersome now).

“Strikes me as being fine. I haven’t run this particular combo, but you’re logic works. To test, I would probably reconvert the ProRes 4X4 back to DNx and then do a split screen side by side on the PC to look for gamma shift issues. Sounds good, though

Thanks a bunch, I’ll give it a whirl.
