Having access to the Post Process settings in cameras within Sequencer is fantastic, only problem is, if you aren’t careful the setting you enter won’t be saved.
It appears that the ‘shot’ file isn’t being set as ‘dirty’ when the settings are updated, so they aren’t saved.
Easy fix for now is to make a change in another part of the camera settings and it seems to save OK.
First time I’ve used Sequencer - it’s brilliant!
