You might have recognized that the thread you've invoked is five years old and you're dealing with similar problems. Feel free to conclude what that means.

Since this is a user forum, if you want to fix your current problem, I believe it doesn't make any sense to complain repeatedly about unexpected behaviour, but to adapt your workflow to what the software does and what not.

If you don't know how, you can simply ask for suggestions how to avoid what you're encountereing and I'm sure that the effect specialists will share their thoughts.

Your nitpicking contains contradictions: either this is a five year old, very basic problem that will never be fixed; or it's something that has a fix and someone can help me with it. You may have also assumed that my asking for suggestions was merely rhetorical or something, that's not a productive attitude.

Since I posted a comment detailing a specific problem I need help with, if others want to help me fix it, I believe it doesn't make any sense to complain repeatedly about my project being cluttered. We have established that is it not the cause of the problem. I have also suggested that this problem is such a basic VFX issue I cannot actually believe I have to find a way to "adapt my workflow" and "work around" something so simple. Did you read that I already re-did that part of the project to get it all nice and clean from the get-go - completely in vain? "Adapting my workflow" means creating something much simpler that makes me want to explore other editing software that doesn't try to let dummy AI do the work for you and lock you out of your creative capacity.

[quote="Crocalu" post=242180]

I nééd V3:DVE to attach to the Bg of V2:DVE#3 (which attaches to the Husk DVE that puts everything on a background). This kind of node-attachment occurs several other times in my video, but should be quite easy to do.


What is the purpose of V3:DVE?

What is the purpose of V3:DVE?

V1, 2 & 3 is are supposed to move across the frame one at a time, from right to left, closely following eachother (but not overlapping).

To achieve the same effect it doesn't really matter in which order they're connected, but that also does not make a difference for the disconnecting routing.

What happens when V3 is connected directly to V2:DVE#3-Bg

Through pass-through nodes V2#3 will then, together with V3, take up the Husk's nodes (V2 on Fg, V3 on Bg). However this disconnects the backdrop V5 from the rest of the routing, and when setting that routing right and moving the red marker to one of the other moments of DVE 'intersection' the disconnecting problem occurs again

Do you think it would work if I replaced the folded DVEs with longer unfolded DVEs that stretch past the other clips to cover all of it, so that the routing can be setup in such a way that it doesn't think it has to correct itself?

What do you have to loose?

Only a bit of time and sanity because doing it that way doesn't avoid the bug.
For example V4 goes into 'DVE4' when it's visible in the frame, but when it's no longer there it is replaced in the routing tab with a pass-through. V5 then connects to that, connecting to the Fg of DVE4 es well as the Fg of DVE5 (which should be its only connected node). So with this other method the problem becomes much worse instead of affecting 1 clip at a time...

The next attempt should be with the videoclips extended as long as the DVEs, however that would mean doubling the # of video tracks and that can introduce its own issues. And as I'm trying it now, the pass-through problem still persists - V5 keeps sticking its nose in the other videoclips' business.
I'll try ending the DVEs right after they're no longer needed and see if that helps, but that dóes require a separate FX track for each separate DVE, which alongside unfolded FX people keep telling me I should avoid at all costs. As I'm trying it now I can already see that even if this method would work, the Titles Fx might cause trouble. V5 inserts itself as its input if there isn't one, so I'll give it a place where it has input as well (but ideally, I'd love it if the Titles Fx didn't automatically get supplied an input when it only really needs an output)

Another problem that arises is that what the Y position of the DVEs has calibrated as being its '0' shifts a set amount. When adjusted, it shifts back to its previous 0-value, requiring another adjustment etc.
I have absolutely no idea what's going on with that, the routing should now be no problem as everything stays in place...

There is a reason that the users here have had trouble working out how to help. It isn't exactly a common problem.

I do a lot of effects work in Lightworks, and I have never encountered effects arbitrarily disconnecting without some underlying cause. I wouldn't expect it at all with folded effects but I have encountered it with unfolded effects when I have added clips to passthrough tracks. Of course it could just be that I have accidentally adopted a workflow that doesn't trigger this problem.

It would be really good to be able to track this down so that it could be identified and, if possible, fixed.

I've now worked around it by putting V1&2&3 in a separate project, turning them into what they should be in the final video, and then exporting that to be used as a simple single videoclip.
The downsides of this are that you have know beforehand exactly what you want to do with V1&2&3 and also that this creates the need to add green backdrops to V1&2&3 to make them greenscreenable for the final video. And even then somehow the greenscreen can't pick up on a transparent, ~70% weaker green background and filter it out (? I adjusted brightness etc and I used one of basic greens from MSPaint as the colour)

As far as I understand it now, the bug has to do with the pass-throughs of the videoclips that aren't present but will be later during the same videoclip of another track. If (DVE) routing could be upgraded to have some kind of optional split in its Bg track, so that the Fg could remain undisturbed while 2 different Backgrounds apply to it?
It could be put on the UI as a checkbox option in the DVE settings, with a timeline thing to indicate where the Bg should split (or add a timed button/indicator for it to the keyframe timeline at the bottom)

You might find some useful tips here: www.lwks.com/index.php?option=com_kunena&func=view&catid=6&id=239840&Itemid=81

You don't need to put each track in a separate project. Just make a sequence of each track, add the effects to the sequence for each track, Then use the sequences as the source clips for your master edit.

If your FX routing is solid for each track, you don't need to worry about Lightworks automatically inserting a pass through in the effects stack when no video is present on a track. There are specific guidelines for building FX stacks in the above thread.

DVE adjustments are much easier if you do one axis at a time in the graph screen with as few keyframe nodes as possible.
Dragging the image around the screen with a mouse is not an easy way to get a clean path result.

The picture below shows how few keyframes it takes to define the fish jumping out of the water at left of screen rotating through an arc across the screen and diving back into the water on the right side. Don't activate keyframes for any DVE adjustment you don't need for a move. In this setup X axis controls left to right position, Y axis plots the curve path from beginning through the apex keyframe to the end of an arc.
The Z axis rotation controls the angle of the fish from beginning to end of the arc.

It is not necessary to take sections out of a project - using unfolded VFX it is possible to run continuous media with VFX across an empty cut in VFX track(s) only- an empty cut initiates a new instance of an effect without impacting preceding VFX.

One can add and remove VFX nodes and media as necessary on either or both sides of the the empty cut.

In the attached example A V tracks media ends - associated VFX tools can be removed - similarly other VFC can be added at an empty cut - this can simplify the VFX process - certainly reduce an overload of PassThrough nodes.

In the demo there is an issue with a slight move on the remaining DVE positioned V track. as the redundant V2 tracks DVE is disabled/deleted

That does need some attention from LW.

If you place an empty cut on a clip with Fx folded it preserves the fx on both sides of the cut too.
