I'm working on a project where I'm editing in Davinci Resolve, but doing a number of effects in Blender. However, when I render out a shot from Blender, I find that the color of the image is slightly different from the source video.
Here's a frame from the source (no color grade):
And here's that same frame after being rendered out in Blender and saved as a PNG (started with the default Blender file, added the clip to the sequencer, and rendered):
It's hard to see in these pictures, but the color is slightly darker and modified in the Blender output. If you look at the waveforms, you can see in the Blender output on the right, some of the sections are slightly brighter (for example, the circled blue section):
I might be able to color correct it to match, but so far that's not been straightforward. It would be much easier if Blender's output didn't dork with the colors to begin with.
What is going on here, and how do I get Blender to not modify the image's colors when rendering?
I am working with 8-bit V-log H.264 footage from a Gh5s (color space sRGB). Again, all Blender's settings are at their default.
