Input Contract Violation when copying layers

[thereARNOlimits]

Hey there,

quite the annoying little thing happening out of a sudden

an Input Contract Violation error

followed by

Things that lead to this behaviour:

copying a layer, in any composition in the project.

Steps I already did:

• purged cache
• restared
• reinstalled AE
• tried on different machine - same error

Happening on OSX 10.12.06 with the newest version of AE installed (15.1.1), happened out of a sudden in one project, other projects are not affected.

Of course that happened on a project that is time sensitive, I mean, sure, could not be the other way round.

Anyone got an idea?

Thanks for you help.

What you can check is:

- Use the Disk Utility, located in Applications > Utilities to repair permission problems.

- Enter into After Effects Preferences > Media and Disk Cache > Clean Database & Cache.

- Maybe your codec is not supported in version 15.1.1. Remember that Adobe has dropped support for previous Quicktime codecs. Have you tried with version 15.0.1?

- I remember that sometimes, when the video files have audio tracks that are empty (silence). This happened to me a long time ago and the solution was to remove the empty audio tracks in the video file.

Thanks for your input.

- The Disk utility is a good idea, haven't thought of that

- cache, as stated hast been cleared

- the layers that I tried to copy were textlayers, and no exotic codes were used in the comp

- silence audio tracks are a problem - I see, good to know, I shall keep an eye out for that

thanks for your ideas, miraculously after working yesterday with the project, calling it a night and starting it again today, the problem is gone...

NO idea why. Like NO. IDEA
