VS X10 Mercalli stabilization in adjacent clips

[MikesMovies]

Hi guys

I have hit a real problem.

Have a video all compiled and planned to use Mercalli to smooth things up.

What I find is I can apply Mercalli to one clip ok, but when I apply it to the next the original needs to be analysed again, if I do that the other clip needs it.
This is madness

How can I fix this other than render the whole thing as one film and apply Mercalli to that?

I tested with three short mp4 clips to the video track. Was able to apply Mercalli to each clip individually with no affect on the others. Perhaps I'm not following your workflow the same way.

Hmm interesting.

There are transitions between each clip?

I begin with no transitions, run the filters, then insert transitions after running the filters.

I think this is possibly due to running Mercalli with Project Format Settings that are incompatible with Share/Render settings. This problem happens frequently. If you make sure Project Settings are the same as what you plan on Rendering, you should have no issues.

Mercalli can work with different settings, like from 4K to 1080p with the same fps for example. But many other differences do not work.

Thanks, so when I add a video file to the time line I always say yes to changing the project to the same settings.
Would that not do it?

[aljimenez]

Replying yes does change the Project settings to whatever that first video clip you added. The problem happens whe you render to different formats that the Mercalli analysis done is incompatible with the render format.

LOL I must have left my brain at the office, can we step by step that please?

My issue happens when I try to apply Mercalli to two seperate (but same format) clips.

[aljimenez]

Yes, let's start over somewhat. I am assuming the issue happens when you render the project and some of the clips that had Mercalli are shown with the "Needs re-analysis" or whatever Mercalli says in that situation. Perhaps my assumption is wrong. Give details on how to reproduce your issue. Because, adding two similar format clips to the timeline, then dropping Mercalli in the first one, performing the analysis, and then dropping Mercalli on the second and doing the analysis should not cause any difficulties. NOTE, you cannot use Copy and Paste Attributes with Mercalli, in case that's what you have been doing.

[MikesMovies]

OK, I am adding several clips of the exact same type to my time line.
Dropping Mercalli on the first clip and allowing it to do it's stuff.
First clip now plays back fine.
When I repeat the process for the second clip, after it has successfully processed the second clip, clip number 1 now needs to be re analysed.
If I do that clip 2 now needs it.

My only way around this was to output all the clips as a single file, re import and apply Mercalli then output again and combine with the others in a new timeline to add effects, photos etc

[aljimenez]

By repeat the process, you are not Copying Attributes from the first clip and Pasting the Attributes to the second clip, right? If you are dropping Mercalli on the second clip, then I can't reproduce that problem; I do this all the time and have not encountered this problem.

If you could create a small project with small video clips that have this problem, I and others here would try to reproduce this problem. This small project would also help Corel fix the problem. Maybe, just share two small portions of the video clips that give you this problem first in some cloud drive, stating your project settings might be enough for reproducing your problem.

Using transitions between the clips may be the cause of this. You may notice that when a transition is applied between clips the total duration reduces a small amount (say, 0.5 sec, but depends on transition duration). That reduction in time effectively changes the scanned duration of the clip which has mercalli on it, thus the re-scan notice.

Test this. repeat your original effort with no transitions applied between clips. Do you still get the effect you report?

[MikesMovies]

Thanks everyone, I did a small test last night and found it all worked.
So either the issue comes on longer clips or when the timeline is far more complex, holding photos and video?
I'll report back on this, I now have a very hard work week ahead so won't get much time but will indeed be back.
Thanks
