Keyframe Stretcher in a Macro for Title Template

I can add a Keyframe Stretcher node to my Fusion comp directly and it works as expected (with known error when shortening the clip), but if I create a Macro including those same nodes to use in Edit page as a Title Template, the Keyframe Stretcher part does not work at all. Is this a known bug or do I need to enable some special parameter when creating the Macro for it to work? I have tried creating the Macro several times with different Keyframe Stretcher parameters enabled, but it never works.

Can you share what you have so far? I've created a couple of them where it did work. So it could be a minor difference. Also 'it doesn't work at all' can mean many things. Can you please elaborate?

" does not work at all." " (with known error when shortening the clip)," are arbitrary statements that need backing. Unless you provide code for what you are doing, I'll assume its the user error. Post to code so we can see.

I added the code - this is a simple 12fr fade up and 12fr fade out just for testing purposes in advance of a more complicated routine. It reveals controls for text, font and I want to be able to time scale the effect once in the EDIT page. Currently trimming length does not pull the end fade-out along with it.

Your macro uses the output of the original merge not the keyframestretcher.
If you view the keyframestretcher it works as intended.
Change the output of your macro and you should be good to go.

Yes, Keyframe stretcher goes to nowhere. You need to make it follow the flow outside the group for macro.

...and of course your keyframe strecher needs to match your animation for it to work as intended as a macro.

Thank you, very helpful - it works now. But still the issue of "stretching" to a length shorter rather than longer. I get a cut to black frame if I trim the template clip (or the original Fusion effect) to anything shorter than the original length. I assume this is a bug, but can anybody get it to work properly?

You should assume that you need more training for this type of work. Look for more information in the manual or search for one of many tutorials online to explain how keyframe strecher works. It works as it always has. It is nothing special it, essentially duplicates frames over a certain range so you can extend the clip like its a freeze frame. Obviously you can't have animation that is dynamic in that range or it won't work. For more advance version animations you use keyframe strecher as a modifier and for simple in and out type animation like titles you use just a node. Its sufficient. If you don't understand how it works. Get busy learning. Tutorials are waiting for you. Or experiment on your own until you get it right.
