Sony A7s S-Log: AVCHD better highlights than XAVC S??
Been doing a few tests with the Sony A7s' highlights. And Ive just found something that seems weird to me:
When filming the exact same scene, with the exact same exposure, if I record it in XAVC S, highlights clip at 100IRE. If I do it in AVCHD, highlights clip at 109IRE.
Again both are at the exact same settings (NTSC, S-Log, same ISO, etc.) except for the codec of course.
I open both in the latest PremierePro and use the Lumetri Scopes not clamped for both. Either in 8bit or float the result is the same.
Can it be that AVCHD is able to retain an extra stop of exposure???
Thanks a million
