Same problematic…
A guy learned to me we can export in .exr 16bits in Movie Render Queue,
And add the setting “Color Output”, enable OCIO in it, and create a config source and choose “Rec.2100-PQ (HDR Video)” as a “Transform Destination” for example.
But my .EXR outputs images are very flat, like a log image from camera, no HDR curves when I watch it in Photoshop’s “Camera Raw”.
So yes, it would be nice to have more information about rendering HDR sequences correctly.
I’ve made a post here : How to export a sequence in HDR ?
But no one reply…
