when using the BCC stabilizer, it automatically creates a subclip on the timeline after analyzing it. The event now has „subclip“ in the name and plays the stabilized version. Whatever I try to render to a separate subclip, Vegas doesn‘t see the stabilized version and renders the original event.

I do not know/have no experience with BCC stabilizer, when it creates a normal Vegas subclip such subclip is put as a Take on the original clip. You can toggle between the original clip and the subclip by selecting the clip and press T-key. Try this toggling and see if it makes a difference.

@Mindmatter Hi, maybe they've changed something, I've got Continuum Version: 2024.5, @Reyfox has the most recent release I believe. What version are you running.

For me BCC Optical stabilizer doesn't create a Subclip nor change the name of the event, & renders without problem,

As I understand it Boris aren't working on the BCC fxs & when they do they create a BCC+ version..

@Gid that is my understanding too. The BCC+ are updated and better optimized versions of the BCC legacy. Boris still has a ways to go, but they are getting there. I guess it costs them nothing to included them until they've all been replaced.

There is Boris Continuum 2025.5.1 with a maintenance update. I have to say, the issues I was having with Title Studio crashing my computer and video driver (AMD 6000 series GPU's) has been fixed.

@Reyfox 👍

Yep, I should have elaborated on that sentence, @Mindmatter what I meant was unless there's a new BCC+ Optical Stabilizer the BCC version I have should work the same as your version.

I found the solution.

The BCC FX has to be put BEFORE the pan crop in the FX chain of the event. Otherwise Vegas does not render it, although it pays stabilized on the timeline.

Now, as to if that makes any sense, I'm not sure...

I can't agree with that, as in my pic above it didn't need to be placed before Pan/Crop, there was no Subclip created & it rendered fine. I believe there's more to this but only testing by others will tell.

I just tried that using BCC 2025.5 - there was no sub-clip auto created purely by adding BCC Optical Stabilizer to a short sample event in VP22b250. Ditto when adjusting pan/crop or when moving the BCC FX in front of pan/crop in the FX chain. The renders to mp4 UHD look all the same stabilisation-wise.

Weird, never had a subclip created with Boris Optical stabilizer. However the FX chain order (before or after the pan/crop can make a difference. As far I understand it, for example, if your Video source is 4K, and your project is HD, then normally the conversion of the video data to HD done by the pan/crop to the next in line FX, so if the stabilizer comes after the pan/crop, the stabilizing is done on HD video, and not on the 4K source. That could make a difference. If the source clip is 4K and the project is 4K, the order will probably make no difference.

There is also a workaround possible, that is to use nesting if having issues with pan/crop and FX.

What do you mean, you "can't agree"?? I'm telling you it worked and solved a concrete issue you don't seem to have, so take it as that.

The project, source footage are all 4K. I render in HD though, not sure if that makes any difference.

In any case, this is what happens in my system, and there seems to be at least some kind of bug.
I don't think nesting will make any difference though, as Vegas just reads the wrong clip to render. It will likely do the same when nested.
I don't know what else to say, it seems like it is an unreproducable issue, as many of you don't see it happening.Really weird.

@Mindmatter Could it be that your subclip is created because you REVERSED the clip?

Indeed! That's the "subclip" mystery solved, thanks a bunch!

So I redid the experiment with a non reversed clip, the issue remains. Vegas renders the non stabilized version unless the BCC is put first in the FX chain.

I can't help further because I do not have/use BCC for stabilisation. I only use Mercalli Plugin or Davinci Resolve stabilisation for the stabilisation of my videos.

@Mindmatter I tried some of my 4K clips in a 4K project and in a HD project, reversed them, then added BorisFX optical stabilizer (after the pan/crop). It was stabilized on the reversed clib (subclip), so I cannot confirm the issue on my system (see signature) with my clips. I am using VP22 b250 with the latest Boris Continuum 2025.5.1

just to make sure - did you try and export it? Like I said, it stabilizes on my timeline, but not in the render.

I put a Mini 3 Pro UHD4K 25P clip on the timeline and added the Boris FX. It rendered just fine.

Boris was put after Pan/Crop. No subclips created. See screenshot.

Reversing the clip, and still no subclips

Both forward and reverse clips rendered and played back as they should.

@Mindmatter yes, I did render (export) it, and checked the rendered result.

@Reyfox I do have a subclip when I reverse the clip. The subclip is take2. Reversing creates a take on the timeline.

@bitman yes you are right about the subclip. Time to get new glasses! l was just testing to see if there were issues with optical stabilization and rendering and paid no attention to it. Thanks for point it out!
