Heya,

Not sure if anyone else has encountered this, I've done a quick search and come up with nothin...

I've been using the atomos assassin with my GH4, and noticed that the footage from the assassin is slightly more contrasty/darker than footage recorded internally. I assume it's something the GH4 is doing, because it only seems to happen with V-LOG, not with standard. (I couldn't really be bothered checking with all the other colour modes...)

Here's a clip of me A/B-ing it on a premiere timeline with the scopes up. V-LOG, then standard. https://www.dropbox.com/s/hiugamp6hfbved4/gh4-assassin-contrast-level.mp4?dl=0

(obviously I don't own a colour chart, a set of pencils was the bet I could manage...)

This was recorded 8-bit, as it was the only way I could record both at the same time, but it happens with 10-bit too. At 4K as well as HD. Both the assassin and GH4 are running the most up-to-date firmware, as of Jan 2017.

Did I mess with some settings somewhere? Is my camera haunted? Is this something other people have noticed?

It doesn't actually bother me that much, I guess this is just a "what's up with that?" kinda question. So yeah. What's up with that?
