Hello! This has been already talked about but I am have a weird gamma shift when airdropping my
export to my Iphone 15. Anyone have this issue? I tagged the export as rec 709a even tried gamma 2.4 and it still does a shift. Wondering if there is a work around or technical fix for this.

Now I have to take another drink! Read these:

and

"How to Deal with Levels: Full vs. Video"
by Dan Swierenga
https://www.thepostprocess.com/2019/09/ ... l-vs-video

and I think both cover the issues and the solutions very well. These videos also cover it:




Understanding color management is also helpful:

"Color Management for Video Editors"

The above articles will explain why things change on different displays, different playback engines, and the importance of calibration and color-managed outputs.

I generally try to export a second or two of SMPTE Bars at the head of the project, and I import the file back into Resolve to check it on scopes to verify all the levels are correct. Using calibrated displays is a must -- without that, you have no idea what you're looking at. We also accept that the basic picture is going to change a little bit on different devices, because that's life.

Thanks Marc! I'll dive in.
