Question

Cambio de color trabajando con Proxys.

Hola.

Escribo por aquí por si a alguien más le ocurre, porque solución por parte de ADOBE parece ser que es esperar a otra actualización, porque después de horas intentando solucionar el problema ( 5 horas conectado a mi pc ) no dan con la tecla.

Es problema es que al crear un proyecto con proxys, cuando trabajas con ellos activados ( por ello los creo) el color de los clips cambia totalmente ( saturación y exposición ) con los que hace imposible editar el color de manera correcta.

No me parece que la solución sea esperar a que saquen una actualización (días, semanas, meses) para poder trabajar de manera correcta, como llevó haciendo varios años y con el mismo flujo de trabajo.

Esto es un programa profesional para profesionales, necesito poder seguir trabajando como siempre.

 

Un saludo.

Ahh ... the files are HLG, an HDR format. Premiere has a completely rebuilt color system for the 2022 series and some things aren't working as the engineers expected. Including proxies from HLG clips ... acknowledged as simply broken at this point. I've had a couple different format/codec combos that people have sent me to test, and couldn't make it work.

 

Well, it can't work if you're working with a Rec.709 timeline, as although you can use a color space override to Rec.709 option on the original media (for most but not all cameras, sadly) Premiere will do the proxies in HLG ... even if you make a new encoding/ingest preset specifically SET to "conform to Rec.709" ... it will not follow the conform direction. I couldn't make a usable Rec.709 proxy not no way not no how.

 

So I passed that on to some engineers, they replicated, and replied they'll get a fix in the next patch they send out ... but we're all still waiting for that patch.

so maybe the OP should work in DaVinci Resolve which seems to have a pretty sophisticated color space environment?  Or is there an alternative workflow in Premiere by transcoding the camera original to a different format...?

The only way to get "proxies" of them in Premiere at this time (late February-2022) is to transcode, you're correct. WITH the Effects tab of the Export dialog set to 'Conform to Rec.709' or SDR ... whatever that option says. So you need to export every clip ... individually, to get the name correct! ... to a low-res ProRes or DNx format, with the Conform option set.

 

Then use the "attach proxies" option in Premiere to see if it will accept those clips.

 

I just realized I hadn't tried using MediaEncoder to do a transcode of a folder of clips, which would be faster than one at a time outta Premiere. I'd have to test before being certain that even works.

you need to tell us your source properties and where the footage came from.    New formats have changed the way they handle color so you'll need to do some research to understand how these new formats have made changes to your workflow necessary.  There's a post that's pinned to the beginning of this forum that probably explains what's going on...

Gracias, he mirado la publicacion, pero mi fallo se produce activando los proxys.

 Sin proxys activo tengo el color correcto.
