v18 Fusion page playback not the same as Edit page playback

PostTue Jan 31, 2023 8:31 pm

I created a custom callout in Fusion. I made it so that the callout fades in from invisibility to full opacity at the start of the clip and then fades out at the end. When I play the clip on the Fusion page it performs as expected. It fades in, remains visible for a time and then fades out. If I move to the Edit page and play the clip, the callout does not fade in, it appears immediately.

There is no other Fusion coding on the clip. I even deleted all of the callout nodes and redid them with the same result.

I have two other clips later in the timeline using the identical methodology. They work as expected.

Is the Edit page showing the full clip? Sounds like it starts part way in.

Thanks for getting back to me. The full clip is playing on the Edit page.

If I am on the Fusion page and play the clip one frame at a time, the callout slowly gets more and more opaque.

If I do the same thing on the Edit page, the callout goes from invisible to fully opaque from one frame to the next.

OK.

Can you duplicate the project, cull it and then share an Archive for us to examine?

This is the "culled" archive file:

https://app.box.com/s/s45r96m8g5vh72yinx9aaoe2pohmm14e

The problem is with the second clip. At the beginning of the clip the callout should fade in, not appear immediately. If you advance frame by frame in the Edit page there is no callout one frame, and it is 100% visible in the next.

If you go to the Fusion page for the second clip you will see that the callout fades in over a number of frames. If you move the playhead to frame 649 and advance it one frame at a time you will see the callout gradually fade in.

The third clip displays the fade in as expected and as far as I can tell the second clip fusion coding is exactly the same as the third clip fusion coding.

Any help would be greatly appreciated.

Thank you

The opacity keyframes are placed before the start of the clip.

Keep in mind that when you open a trimmed clip in fusion, you have access to the full untrimmed clip.

Nice catch, Pan.

So my original assessment turned out to be true. ;)

Guys, Thank you so much. I am just getting started with davinci and it is great to have a responsive community like this to help when nothing seems to work the way you expect.
