Problem: Dynamic Zoom is drifting

Hello,

Resolve Studio 18.6 on Windows 11

Settings:
- Dynamic Zoom
- Ease out, Ease in

When I set Dynamic Zoom begin/end (green/red) areas to zoom into the edge or corner of the frame -- it doesn't do a smooth zoom like it does using the defaults without moving either target rectangle.

Even though I can see the begin/end areas accurately in the Dynamic Zoom view -- i.e. both the edge of the green rectangle and the edge of the red rectangle are at the edge of the frame, -- when it executes, the zoom drifts around and pushes the edge of the frame out of the picture entirely for most of the zoom, only showing it at the end of the zoom action.

I've been trying to overlook this problem but I'm zooming in on a Powerpoint slide so that drifting really looks unprofessional.

Has anyone else seen this? Is there a fix?

Thanks,
Robert

Give it a try with Transform instead of Dynamic Zoom.

Ok thanks. Is there some ready training on this? I have over 150 slides displaying during a 1-hour presentation zooming into different areas of the slides, so I need to set some defaults or actions if possible.

With Dynamic Zoom I selected all the slides and set Swap and Ease Out so I wouldn't have to do those things individually for every slide. I can just adjust the Zoom area (in theory, not in practice unfortunately).

Thanks,
Robert

If you haven't had a chance yet, I think the best place to start with Resolve is the Beginner's Guide.

https://www.blackmagicdesign.com/produc ... ning#books

However, don't approach the study with an eye to solving a specific problem. Approach it with the goal of just learning the basics.

Once you have the basics under your belt, then you can work on your own projects, and maybe continue with the other training books if they would help.

But definitely the Beginner's Guide as a very first step.

Understood.

I was hoping for something more in-depth. From what I can see, the Transform view won't do what I need without keyframes. That's more work per slide than I did doing Dynamic Zoom for each slide before I set all their defaults to Swap/Ease Out.

I found a MrAlexTech MagicZoom in my library that I'll try.

But the current Dynamic Zoom behavior is a definite bug, unfortunately.

the dynamic zoom ease function is slightly broken, from the very beginning when it was introduced. It does an ease-in on the zoom correctly, but not on the position.

so what you see is a linear motion on the position, and an ease on the zoom. which makes the image go off-screen while it's still "accelerating" on the zoom. the bigger the zoom/position change is, the more you see this.

solution is a manual approach, or indeed a plugin like you found.

Transform view won't do what I need without keyframes.

Well, yeah. That's how it works.

But I'd rather not do that much work on each of 150-200 slides.

Ok, thank you.

I may try reporting a bug to BlackMagic Design, they did a great job fixing another bug I posted here (Resolve dropping frames at the end of many random clips when copying many clips at once to a different timeline).

Best,
Robert

I get that.

But if the other way doesn't work...
