@NickHope is this a known issue?

this might work once once rebooted etc, but not repeatedly, in the long run..just sayin'..

@NickHope is this a known issue?

No, and a very brief test here has it working OK for me. Can you come up with a repeatable process to demonstrate, or even a demo project?

Seems, that the original has to be out of view somehow. On different track, far away in time.

Then pasting attributes with velocity envelope fails. However, touching event trim, heals it instantly...

Looking at it a bit closer it seems, that the velocity is working, just the envelope is not displayed correctly.

@klt In my scenario it also happens when I copy>paste to the adjacent clip. And Yes, as you say, it is only the envelope that's not displayed properly, which can be 'healed' by trim the header forward/backward a frame!!

I still can't make this happen.

Seems I could reproduce. The event you paste the attributes to has to be untouched since you opened the project. So my steps to reproduce:

-start a new project.

-add 2 events to timeline

-edit one event, so that it will have event velocity

-save the project, close Vegas

-now start Vegas again, open that project

-copy the edited event

-paste attributes to the other event: for me the velocity envelope is garbled now.

IF I trim the event (end or start) BEFORE I paste attributes, the velocity will show up correctly at first.

IF I do the trim AFTER pasting the attributes, the messed envelope will be healed.

Because of my curiosity, I tried to save the project with the messed (still working) pasted velocity.

Whenever I open this project, the envelope still shows up badly. I have to make a trim to make it look right...

Thank you kit. I've reproduced this now and it goes right back to VP10 (the oldest version on my machine).

If Paste Event Attributes or Selectively Paste Event Attributes is used to paste a velocity envelope onto an event that existed on the timeline before the last time a project was opened, any keyframes in the pasted envelope all appear to be on the first frame. They cannot be dragged to the right and new keyframes cannot be added. However the keyframes affect the event's velocity correctly, and are displayed correctly if the event's length is subsequently adjusted.

I bet this old comment from 2010 refers to exactly the same bug.

I reported with a support request [Ticket#2018111717000624].

Thank you @klt thank you @NickHope excellent bug smashing ;-)
