I was recording MLV Dual ISO and processing it to jump to DaVinci but when I open it, just display totally black.

SETUP:

Thanks for reporting. Which version do you use?

bouncyball-git commented 6 years ago

And upload shortened original MLV somewhere to test.

Okay... very strange. If I export any dual iso file it is working fine in Resolve. If I apply the posted receipt on the same clips, export and import in Resolve, the clip is just black. But it is black in Resolve only. All other apps show the same dngs the right way.

It seems to be the Deflicker Target. Set the value to 0 solves the problem also with the posted script. @bouncyball-git : what does deflicker target to dual iso on cdng export?

erikeah commented 6 years ago

@masc4ii @bouncyball-git DeFlicker to 0 solve the problem. Thanks a lot!

masc4ii commented 6 years ago

@erikeah : nice to hear. But @bouncyball-git : could we analyze what was the problem? If that parameter combination doesn't (or can't) work we should disable it.

erikeah commented 6 years ago

Yes, of course we can. Just tell me what do you want and i'll provide you.

bouncyball-git commented 6 years ago

Phew... strange it only changes one tag in dng header that is all :(

masc4ii commented 6 years ago

One single tag? Then I think that is a Resolve bug. All other software is working fine with these dngs!

bouncyball-git commented 6 years ago

Yes it's called tcBaselineExposureOffset

bouncyball-git commented 6 years ago

We could remove deflicker feature entirely b/c it seems no one even understands what it does, how to use it, so it has no future (I doubt it ever been used in MLVFS). And as now we can see it even causes issues.

Also without respecting BaselineExposureOffset tag NLEs can not take the advantage of this feature at all and, I guess, this is only used by adobe...

masc4ii commented 6 years ago

By default it is 0. How about just hiding it in the GUI?! If someone needs it, it is possible to show it by some simple changes to the code and recompiling... or just hacking the receipt file :-D

Edit: Hidden. https://github.com/ilia3101/MLV-App/commit/557803e8a489573b180730c33454b0c7847b8ff9

Good suggestion! Deal :)
