Black Levels Changing

[Struan]

Hi there! I've created two DCPs from the same file.

DCP 1 was made in version 2.14.56, letterboxed in a flat container, Interop.

DCP 2 was made in version 2.16.5, cropped in a scope container, SMPTE.

I believe these were the only differences, but DCP 2 looks washed out when played in the player. DCP 1, in contrast, looks great. Unfortunately I have no way to test the file out in a cinema. I'm hoping there's a difference in the way the player is playing them back, rather than the files themselves? Any ideas? Thanks!

Is it possible to make a clip of the source file you are using and to send it to me? carl@dcpomatic.com

[Struan]

Sure thing! You mean the original ProRes?

[carl]

Yes

Thanks! Sending via WeTransfer.

Did you use the same project file, that is, first created in 2.14.56, then afterwards loaded the same file into 2.16.5?

[Struan]

I did, yes.

This is a very good question ... 2.16.x handles video range in a more correct way (in theory) but it looks like something goes wrong when reading in the 2.14.x file.

I can see the difference when loading the 2.14.x project into 2.16.x but not when creating a new 2.16.x project with the same source file.

I'll look into this as soon as I can... here's a bug in the tracker.

Oh, excellent. So in the meantime I can re-build the project from scratch and that should solve my problem.

Thanks, guys! I'm really grateful to be able to use this program.
