To be clear, we're referring to the color curve dedicated effect in the vegas effects menu, and not the color curves nested into the color grading panel, correct?

Correct. I don't see the problem if I use a color curve from the CGP.

OK, I seem to remember the old color curve effect being from a very ancient version of VEGAS (perhaps even the first to offer video?) and it was never updated to be compatible with 10 bit media, so you need to use the CGP one to not have it mess up your media. That said, I only remembered it clamping nit values to 100 nits when editing HDR, as if it were 8 bit media... not causing decoding errors. I'd still recommend against using it for anything above 8 bit. The CGP panel one is better anyway, it's easier to make edits to the bezier points and such, as the handles are displayed larger.

The Vegas Color Curves plugin is listed in the 32-bit compatible fx panel, so I think it ought to work in 32-bit mode. Are you suggesting we should ignore this?

no, but I am suggesting another, even better alternative already exists, which you can use on your projects right now without having to wait for the color curves fx to be updated.

I appreciate you pointing out a viable workaround.

I do, however, prefer to work with the old-school fx interface, and if Magix is intending to deprecate it, I would appreciate formal notification of that.

I doubt they do plan to deprecate it, they just haven't got around to updating it yet. It may be a little while, since there is another better working color curves option currently available, but they will get to it. I'll make sure they know this is happening.

I doubt it's being deprecated but 32-bit has changed over time with new modes like ACES and HDR and there are a number of legacy Fx that have yet to be updated. I'm hoping for an overhaul myself so we're left with tools that just work.

I have heard the developers openly discuss on the forums that they planned on taking a break on new features eventually to do just that, so all we can do is wait and see... they did just dump a ton of new features on us, so maybe now's a good time for that internal rebuilding to take place.

I thought this last update was the "stability" one but maybe I misunderstood that.

@Illusion as it happens I have an A7C also and didn't think to test it. Unfortunately (fortunately??), I can't replicate this with clips from my A7C. My body is running firmware version 2.0. Maybe your camera is running an older firmware version?

No, FW 2.0 here

This is useless.

The HEVC fix was the heart of the update and for stability.

I'm happy they kept building out features like the color grading panel selective color abilities too as it felt incomplete at launch.

Well, me being old-school Vegas I'd love to see the curves-vs-curves features in the grading panel available as an fx for the traditional clip-based fx chain.

Here's a share link for a clip from my RX100 M5 if anyone wants to play around with it:

https://ufile.io/7io8ksdy

Click the "free" download option. That should be available for up for 30 days and claims no malware.

To replicate, open Vegas, drag the clip onto the timeline (I have properties set to automatically match). Add the Color Curves FX at the clip level, then drag the left handle to brighten/darken the image. Everything should look fine. Now change the project properties to 32-bit video levels, go back and drag the handle around again.

If you're going to see it, it'll be obvious.

I can repro the problem you had.

Small update here. The problem with A7C black frames I posted was with 32bit Full Range. If I use 32bit Video Levels, I have no issues.

The HEVC crash fix was the only major crash that was affecting pretty much everyone prior to the update, they can tell how many people are affected by a certain bug by looking at crash reports... and that one was so widespread that they retroactively fixed it in 19 as well.

Look at that new feature list on this last update, VEGAS 20 didn't have a list that long when it launched. I imagine this was rounding out the new features they'd hoped to add to 20 when it launched, but didn't have time to.

j-v try it in project-properties --> pixel formal --> 32-bit floating point (video levels).

I don't ever work in 32/full -- sounds like that's where illusion noticed an issue with A7C footage. I'll see if I can repo that

my main system is a current Dell XPS laptop with an NVIDIA GPU enabled

I did and saw no difference.
So no problems on Laptop from signature
