Might be a bit of a rookie question here–– Looking for some more insight into the most efficient method for maintaining color accuracy when importing OpenEXR files… I need to convert to ProRes4444 for a client. I noticed, by default, Flame is tagging the color space as ‘unknown’, however, it seems…

Or if you feel like sending them an example of your best guess. Lets assume this EXR footage is Linear Rec.709 I would tag the footage as scene-linear 709/sRGB [tagging] and then output a ProRes4444 (12-bit) making sure you use LUT in the export window and select ViewTransform and hit Edit. […

And what colorspace are the EXRs?

I was told they were rec709. Color space says “unknown” when the clip is highlighted in the Media tab before import. I have tried tagging the clips as rec709 prior to import and that doesn’t seem to do anything. The clip preview just shows a very saturated image that is nowhere near the color when…

The clip’s colorspace AKA “Input CS: Unknown” is listed in the metadata in the media hub before import is Unknown most likely because you have the Tagged Color Space on the bottom of the Import module set to Unknown.

In other words, the Metadata Input Colorspace, Input CS, is a result of what you’ve tagged it. Its the effect, not the cause.

Unknown will not apply any colour LUT. You seem to be getting a better result when you tag it as Linear (sRGB gamma). With the footage tagged as unknown it appears over saturated. Have you seen this footage in any other preview or is it so obvious that it is wrong? Is it overly saturated and does …

Some applications linearize when exporting as exr by default. So if grading was for broadcast it is supposed to be Rec709/BT.1886 (gamma 2.4) but was exported as scene-linear sRGB/Rec709 when using exrs. So you only need to gamma transform back to gamma 2.4. But I wonder why someone would use EXR…

Keep us posted @nick_devivo with what the client says…let’s be sure to keep this thread about @nick_devivo 's particular situation. I’m loving the dialogue, please let me know if it makes sense to split some of this into a different topic so we can ensure everyone has the space they need to do thei…

Thanks for the reply and the screen grabs. Very helpful. Tagging as Scene Linear rec709/sRBG seems to be fixing this issue. And yes, I am able to view the individual frames in Finder preview and see that they clearly look wrong when imported into Flame. They are very dark with high contrast levels. …

I wouldn’t mind a split–I’ve got a searingly hot take about image compression. Haha.

I wouldn’t mind taking this discussion to another room :slight_smile:
