Disappearing grades

[Stig Olsen]

Hard to tell… Did you have more than one timeline created by several EDLs?

[Michel Aboudib]

I did. When I noticed the missing grades, I had 4 sessions, created from CMO. Some pointed at the same media, one pointed at a completely different media folder.

Ok, If the sessions are checked and the different versions – the only thing I can imagine is that the project was not properly saved for some reason.

[Michel Aboudib]

I compared all the sessions in that project and I think I know what happened, but I have no idea why.
Here’s what I did:
– I had first created a session from a rough cut to run some tests while waiting for the editor’s final version.
– When I got the final version, I made a media managed version because I had to convert FX footage that Resolve couldn’t open (it also solved reel issues I think).
– I loaded the xml from the media managed version. This is the session I graded. It was supposed the “new” footage, from the folder created by the media management tool. I did’t pay attention while grading, as I pointed Resolve to the right folder, and all was running fine every time I opened the project. I saved a lot. I looked again after the lost grades issue and it seems some clips were linked to the old folder (media manager preserved names, etc, and all clips except effects were prores).
– When I was done grading, I rendered using the source setting and exported an xml, which I reimported to do some tests.

Now I have the two first sessions (rough cut and the one I graded) with mixed up grades. Some test grades from the rough cut were applied to the final cut, and clips from the final cut had lost their grades. However, the rendered and reloaded version seems to have all the grades I though I had lost: all the nodes are there and al clips have the little rainbow strip.

I have no clue what happened. I just remembered, I did click on reconform from folders by accident. That was after reloading the rendered clips. Could that be the cause?

Is there a way to apply all the grades from one session to another one? That would fix everything.

It is not a big deal, the project is finished, but I want to avoid having that problem in the future.

Save stills from the session with correct grades, open the new session, and apply the corrections from the stills to the new media

[Michel Aboudib]

That’s what I thought. But it turns out the nodes are there, for most of the grades, but they are “empty.” They have all been reset.
I’ll be more careful next time, and will track all changes, in case it happens again.

Thanks for your help.

Ok, then it could be the base memory.

[Michel Aboudib]

What is the base memory? database related?

[Michel Aboudib]

Okay so, I fiddling some more, in a clean project. I decided to see what would “reconform from folders do.” I am not familiar with this fonction. I don’t what it is for exactly, but I just wanted to see if it would potentially mess up a previously properly conformed project. IT DID. Some of the clips remained the same, other were link linked to completely unrelated clips (different name, reel, etc, but from the same project.
I think that is what messed up my previous project.
