Trim Paths feature on shape layer creates flickering on anchor points

[Kevin Knutson]

Ridley-

Yes, that’s the effected zone for sure. I was able to port the project to another identical system on site and low and behold, the render is fine (same exact media, same exact project, same exact comp). Which makes me uneasy about fixing the issue on my machine.

The long GOP suggestion is an interesting one, however, the same shapes are used in other comps with footage from the same shoot, and seemingly at random don’t experience the flicker.

All footage is input and output as ProRes 422. This is of course transcoded from the native camera files (canon 5d mkIII).

The user Vishesh gave me a project with essentially the same exact shape, and I used that in the same way I’ve used my own shapes with the footage from the project, and there was no flickering.

I guess now, I need to figure out what needs to be reset/purged/deleted/changed/re-installed on my system.

Glad I could help.

Just try an experiment:

Increase the stroke thickness to say 3 and then check out the rendered file. The video that you have uploaded has very thin strokes which might a problem. Just a guess.

Thanks Vishesh.

I don’t think that’s a practical solution, unfortunately. The line thickness has been used without incident or issue in several projects. The weight of the line has successfully been used and adopted in the design standard for ongoing content in this bucket.

The heart of the matter is not rooted in design aesthetics (I’m convinced) but a feature not behaving how its intended on my system (see above that another system rendered the identical project just fine).

I would be open to suggestions on how to purge the issue out of my system however.
