Mplay Render vs PNG Export difference

Hello

I am trying to import a image sequence to put a animation together in AE but when I export a image sequence from Mplay the exported image sequence is much lighter than what rendered in Mplay. I of course prefer the Mplay quality, given that it uses the Octane settings to my liking. What is going on here? I have this problem with both .png and .exr files.

I am not interested in doing much color correction in AE, I like that with Octane I can get the look I want, fast, so this is quite annoying to me.

This problem sounds like a gamma correction issue to me. Probably you could try to save the images disabling the "Convert to Image Format's Colorspace" option and enabling the "Output Gamma" set to 1, because the Octane images already have its own gamma and tonemapping corrections.

Hey you ever figure this out I'm having the same issue when I render out my animations. The EXR files are much brighter and washed out than what I see in the IPR. Feels like its missing a color profile or something in anycase its very frustrating no matter what I do I cant output what I see in the IPR. Thanks!

Update: Tonemaped output seems to work when I exort to PNG but when its EXR the image is super washed out and brighter. EXR seems to work when I select Untonemaped, is this normal? I render tonemaped EXRs in the C4D plugin all the time.

Thanks!

Hmm, I'm not sure, but the tonemapped EXR files could include even the gamma correction, that later could be double corrected by your post application. I suppose that if you want to save a tonemapped EXR, you should set the gamma to linear to avoid this double correction, although usually the users work with untonemapped linear EXR files.

Thanks,

in you are in float you can do the reverse by setting the gamma to .45454545
