collecting ideas to build up a AVCHD - ProRes - Resolve workflow.

    See Building FFMBC/FFMPEG on Mac OS X Lion:

    FFMBC is a version of FFMPEG that came out of the lab at the BBC. It’s designed for Linux, so it takes some extra effort to build it on Mac OS X.

    (That's why I say to get somebody to help you install it. Then you're away).

    BTW, I think @artiswar 's workflow is clever. Just collecting ideas here, after all.

    Yes, I use FFmbc on Linux and only in command-line mode. Lots to explore. FFmbc also works on Mac OS command line.

    However - the sort of thing you might find useful would be an older, separate machine as a mini render-farm!

    @goanna thanks again - but I see at http://hdcinematics.com/tools/AWU.html it's a WIN workflow. I am on a Mac.

    PV member @notrons also made a very user-friendly GUI for FFmbc. Maybe if we all ask him to include one more ProRes preset for his DSLR Post Prep application?

    Another GUI is not an encoder itself, but a gui to use ffmbc. You basicly put ffmbc.exe in the right place once, then you can choose.from a multitude of presets, includibg Prores. The program takes away to remember command line paramaters from you amd allow batch processing.

    The quality is as good ffmbc (bc=broadcast).

    @thepalalias Is there an advantage of using Cineform MOV instead of ProRes? Coming from FCP7 it was almost ProRes for me.

    There a two handicaps with conforming all files to another format: it takes a lot of storage space which I don't have when I am shooting on location with my MacBookPro. It takes too much time.

    Last time I went through the clips in Adobe Bridge immediately after the shooting with my client and we put them quick and dirty in a timeline. That was perfect for me beause it saved a lot of time in editing - but I lost more time after because at home I had to pick the selected files, convert them to ProRes, set the same in and out points and replaced them in Premiere "replace with clip" This was really stupid & boring..

    @peaceonearth You don't have to use ProRes in the newest update of Resolve 9. You can use Cineform MOV instead if you prefer.

    If you transcode at the very start of the project (before you start editing) you will have a lot easier time down the line and can take advantage of things like using FCP XML to export the multi-track session into Resolve (or from Premiere to FCP to Resolve if there are any issues with the FCP XML in the Premiere version you use).

    The EDL method does not work well at all on the projects I do because they often use several layers and predominantly use fades rather than hard cuts.

    @Meierhans thanks for this link. "In case you are not so good " -> I am at zero with this.

    Are you using this encoder? How's the quality?

  • MeierhansMeierhans

    In case you are not so good in command line check this out: http://www.stuudio.ee/anothergui/

    Its a GUI for ffmbc and other command line based transcoders.

  • goannagoanna

    @peaceonearth

    Since you'll probably just be making repeated use of one batch command string, it should be easy enough once you can get someone to install it for you.

  • peaceonearthpeaceonearth

    @goanna thanks for this hint, but unfortunantelly I don't understand how to handle this encoder

    @artiswar first try failed, scene detection splitted single clips. I will try again but I see a handicap of grading exported sequences: if you have to change sth in your sequence you have to back to the NLE, export again and start grading again from the beginning.

  • goannagoanna

    Since we're in idea collecting mode, FFMBC will convert all your source files to ProRes too - and fast!

  • artiswarartiswar

    @peaceonearth - I only use 444 so its as lossless as possible. The above workflow has a lot of encoding steps and I really try to limit the degradation each time.

  • peaceonearthpeaceonearth

    @artiswar thanks so much! I will try it immediately. Do you think ProRes 444 is necessary? I normally convert to 422 HQ.

  • artiswarartiswar

    @peaceonearth - All is still not lost! Check out my workflow!

    1. Edit native .MTS
    2. Apply gamma fix to all clips
    3. Try to keep your entire edit on one track, if not, collapse your final edit across the multiple tracks down to one track and export an edl. (Optional)
    4. Export the entire sequence in either ProRes 444 or DNxHD with maxed setting.
    5. Import the rendered sequence using the EDL you created. If you didn't export an EDL, tediously go through the project and use the Scene Cut Detection tool in Resolve to cut up your large clip into small clips.
    6. Grade away!
    7. Export from Resolve as ProRes 444 again and bring this file either back into Premiere or Export the audio separately from Premiere (I've had issues with DaVinci messing up my audio) and pair the ProRes 444 file up with the audio in Quicktime Pro 7. Export to necessary delivery codec.
