Question

Adding a Lens Flare to an Adjustment Layer is warping time!

Hi Guys and Gals, I could use a sounding board to help save my sanity.

 

I have a video track, above which I have some text. These are bound together by a Track Matte Key.

The text is animated to scroll from off-screen right to off-screen left. The video track can be seen in the characters hence the Track Matte Key.

All good so far.

 

Above these I have a simple adjustment layer for Lumetri and a crop.

 

In order to keep the effect above any other video tracks that I may add, (so that it would always be visible), I have a Lens Flare sitting on the Adjustment layer.

 

The Lens Flare centre is animated to move from the left to the right of the screen.

 

The problem I have is that when the Lens Flare effect is turned on, (on the adjustment layer), although the video track keeps perfect time, the text track animation runs quicker by 5 full seconds....

 

So in playback, the text leaves the screen 5 seconds early.

 

BUT... the x coordinates of the text are correct i.e. when I play the composition without the effect turned on and then pause the composition, the x coordinates of the text don't change if I turn on the effect (while still paused) even though the text vanishes (becasue it has shifted off screen 5 seconds quicker than it should have done).

 

What am I missing? As it stands I can't work with my playback effectively becasue my scrolling text and Lens Flare dont like each other.

 

Any thoughts would be welcome.

 

Thanks.

I would try nesting the video and the text.

    Thanks Richard,

     

    It sounded like a good work around, but sadly it makes no difference. Even with the text track and the video track nested together, when I turn on the Lens Flare effect in the adjustment layer, the nested text still shifts forward in time.

     

    It makes no sense, although from reading through the forum, there appears to be a lot of questions associated with keyframes and the adjusment layer and the subsequent spurious effects. 

     

    Open to other ideas 🙂

     

    Cheers

    Adjustment layers are not simply another 'video' track. They are simply a tool to hold effects, and some effects work "normally" on an AL, some can't. The ones that can't do not at all behave like an effect applied to a video track.

     

    So ... I'm strugging mentally to see what you're doing. I'm not sure why you're using the AL for the color work. And from dim memory, I don't think lens flares work correctly ... reliably ... on ALs. I think those need more to be applied to 'regular' clips whether video or graphics.
