Workflow RAW a ProRes 4444 con Photoshop via Bill Rich

Estuvimos intercambiando opiniones con Bill Rich esta semana. Él compartió su experiencia con la BMCC y una iMac 2010 con intel core2duo 3.06mhz y 4gb de RAM.

Como se puede ver en el foro sobre Post Producción de BlackMagic Design en este vínculo http://forum.blackmagicdesign.com/viewtopic.php?f=3&t=931&start=20, Resolve no tiene soporte para ese tipo de máquinas, sólo para iMac 2011 y posteriores.

Por eso, Bill ideó un worflow muy interesante a través de Photoshop que tiene una ventaja: permite convertir los DNG de RAW a Pro Res 4444, es decir, manteniendo la profundidad de color al cambiar a Pro Res, por lo que no es necesario volver a procesar los DNG nuevamente, ni XML ni nada.

Workflow

1. Corrección de color de los DNG via Photoshop.
2. Conversión de los archivos a JPGs de alta calidad.
3. Reimportación en Photoshop pero como secuencia de imágenes
4. Exportación como video ProRes (similar al workflow de los Timelapse)

Agradezco a Bill Rich por suministrar esta información tan útil para muchos, sobre todo para quienes estamos más al sur del mundo y la tecnología demora más en llegar. Aquí el intercambio via Facebook con Bill y otros usuarios.

Took the BMCC for it's first shoot today and it was really easy to work with. .I really like using manual lenses on this camera! Now to my first problem.. Davinci Resolve doesn't seem to want to play with my iMac.. it installed fine.. I was able to open the program fine.. but the second I tried to import the raw files error city.. apparently my GPU doesn't have enough memory.. then it went downhill from there.. looks like I'm going to have to get Adobe lightroom to process the raw files from the BMCC.. bummer.

  Kiefer Gilsenan What version iMac is it Bill Rich?

  Bill Rich It's the base model 21" iMac.. What I'm finding on the BMD forum for configuring Resolve is a LOT of folks are having trouble with it.. even on some top spec machines.. the last time I tried to work with it Resolve won't even open stating that the Cuda driver isn't loading..

  Justin O'Newton People are saying the ProRes is pretty flexible, so it probably won't make a big impact shooting in it for at least the short term.

  Leandro Ariel Braier Bill, are you talking about the Resolve 9.1?? If you aren't, try downloading the recent upgrade for free with the license that comes with the BMCC. I have that same iMac and could work fine with RAW DNG with Resolve 9 lite (meaning 1080p) so I guess it...See More

  Robert Rogoz Also it would be nice for workflow just to have a simple utility to transcode CinemaDNG to 12bit ProRes444.

  Leandro Ariel Braier Robert, look at this thread. They say you can do that with Resolve, Final Cut Pro X & RCXProhttp://forum.blackmagicdesign.com/viewtopic.php?f=2&t=1763#p9709

  Robert Rogoz Yes, but I am talking about a separate utility. Dump in CinemaDNG, enter key words, shot log info, transcode to 12bit ProRes444- as stand alone and self containing utility.

  Bill Rich I love the idea of having an simple utility to transcode the cinemaDNG files into prores. Especially those of us that don't have computers powerful enough to run Resolve.

  Bill Rich I didn't have luck with Resolve9.1 either.. BUT.. I did figure out how to precess the cinemaDNG files in photoshop! I'll most likely shoot mostly in prores.. but it's nice to know I'm able to shoot in raw when I want. .it's just a longer process.. 
  when I have time I'll put together together the video I shot the yesterday

  Bill Rich I'm going to continue testing with resolve.. it is by far the easiest workflow for working with the raw files.. I'll be interested in see the software the Digital Bolex folks are including with their cameras (if/when they ever come out) to convert the raw files for edit.

  Robert Rogoz There is also known issue with debeyer process in Resolve introducing moire to the footage. So the utility that would properly debayer the footage (without introducing moire) that transcodes to 12 bit ProRes 444 would provide the best workflow: shoot D...See More

  Bill Rich I've heard that about Resolve.. 12 bit 444 would be awesome!.. not sure if it would happen with this version of the BMCC unless it's something they could do with a firmware update.

  Robert Rogoz I think that a computer conversion of DNG to ProRes would be better. Having to option: ProRes444 (12 bit) and ProRes 422, or just ProRes444.

  Bill Rich I just ordered 16gb of RAM for my iMac.. hopefully that will speed things up on my computer.. uninstall resolve and the cuda driver and re-install it.. I think that 'should' do the trick.

  Bill Rich Sure Leando! I've been doing some research and I think one can really do a great job of tweaking the .dng images in the photoshop raw reader.. and output high quality 16bit .jpgs.. then either work with them in you NLE as .jpgs.. or convert them into ProRes video clips. the disadvantage of the workflow is if you need or want to use the recorded audio you have to sync up the .wav file manually in edit.. I still think that resolve is the easiest workflow as it keeps the .dng file in it's video form with audio attached.
