FilmConvert OFX resets in Davinci Resolve 12

[Christoffer Glans]

I did a grade with filmconvert and when opening up the project to continue, all the settings, including the Red Raw settings has been reset, meaning I lost my entire grade.

This might be the shittiest bug I've ever encountered in Resolve.

Let's not jump to a premature conclusion. Are you sure you saved your grade session? The reason I'm asking is although anything theoretically possible, what you describe makes absolutely no sense. Even though I used Film Convert with Resolve 12, I had never had an issue with it resetting color grades and metadata adjustments. Anyway, it's very easy to test your theory. Just apply some grades with FilmConvert, save and reopen. Are the grade still there?

Beware that from Resolve version 9 it handles RAW settings differently than before. It doesn't save RAW settings anymore in the timeline but instead attaches them to the clip, meaning that if you use the same clip in another timeline and change the settings, it will update the settings for all other instances for that clip. I found out myself (only in version 12 really) when RED clips would mysteriously have their settings changed or reset and losing all grading.

If you want to keep settings per clip in the timeline then there is the option 'Save with Version' in the Camera RAW settings.

Not sure if this is what you are encountering but it could be, no?

I don't have more than one timeline and the RAW settings have been applied through the project settings instead of per clip. I saved the project after I rendered out the grade, so on the delivery page I can see the settings I did last. The RAW settings have been kept except the gamma settings and the FilmConvert is on every clip but without the settings applied, all are reset. I did the grade by setting up a base setting for the FilmConvert plugin and applied it to nodes and then balancing them. So the base settings were monochrome and that is what I applied to the clips while working. They reset to base settings on all clips, which makes no sense since I used a template setting and they got the monochrome film conversion from the get go, not from base settings.

So some settings, like the delivery page and ISO and basic wheels adjustments stayed while the FilmConvert, the gamma and so on reset to base settings. In other words, I did not miss to save the project and this doesn't have to do with RAW settings reset since the reset has affected more than the RAW settings.

What troubles me is that if I'm doing critical deadline work one day to continue the next day, I'm not sure that the grade will stay when closing the software. This bug could cost me entire jobs, so that's why I call it the shittiest bug I've ever encountered. If it happens in a worst case scenario it's not gonna cost me time but a lot of money.

Yeah, I just ran into this on a project the other day. My opinion is that this is not a feature -- it's a bug. To me, the individual clip Raw settings should not ripple through to every clip in the timeline. I'm baffled as to why they can't just treat the Raw settings just like any other adjustments -- though I'm very much aware where the Raw settings happen in the order of operations.

I have never seen this particular bug. My advice to work around it would be not to use FilmConvert, and instead come up with another correction that does the same thing. Aside from the grain patterns, I don't think there's anything going on within FilmConvert that can't be duplicated with curves, primaries, secondaries, keys, and log controls.

If you absolutely have to use FilmConvert, then I would bet if you only had this OFX plug-in in a single node, then copy-and-pasted that node where you needed it, all the settings would follow. I've done this with Sapphire, Red Giant, and Tiffen, and all of those work as expected (albeit slowly).
