After Effects error: unimplemented function

    Finally figure it out! Turns out the media cache drive was full, after a cleanup everything it's back to normal!

    I installed the update and NOW whenever I tried to playback footage that I imported I get: After Effects error: Unimplemented function. It's so annoying and there's nothing unusal about the files I'm using. I've used the same files for other versions and this error keeps coming up. I pay so much for this subscription and it this stupid buggy program doesn't work. I also tried cleaning out the media cache and that didn't work. I'm currently trying to download older versions and see if that does the trick. This is so stupid smh.

      I'm having the same error, everything was working fine with the version 24, but when I update to the version 25.0.1 it simply stop working all togheter. I tried convert the .wav file to other formats, even to .mp4 but the error remains. Even reinstall the version 24 but now it's giving the same error.
      My setup it's a i7 8700k with 32gb of ram and a RTX 3060.

        I had the same issue (10::48), which was totally fixed after clearing my cache and making more space on my cache partition. Hope this works!

        Same error here as well. 10 ::: 48

         

        And the audio is corrupted as well. File plays fine in other Adobe applications. fix would be insanely appreciated. Now my After Effects is non functional for me.

        I too am having this error pop up, with the 10 :: 48. It seems to be having problems with normal audio files all of a sudden, and its progressively worsening. At first it was happening if I would drag in sound instead of importing (through File>import>etc). Now no matter how I import I'm getting warnings and it wont play the new audio files added. It is a pretty big sesh so I'm guessing its capped out in some form. Never know, I've had to dance around so many versions of After Effects trying to outrun BUGS that pop up like this that I know it could be a legit BUG.

            Hey I brought the file into audition and exported it as a wav and that seemed to work for me!

            Hey Rafael, I had the same error a long time ago, the error 10::48 could of this.

            If the error occurs during preview it might be because it's too heavy for your RAM to render for the preview (if that make sense).

            I don't think it's fixable since the error it's not from AE itself. Maybe try to reduce the effects you added or the color correction if you added that.

             

            Hope it helps.

            You could also comment on what kind of effect you are applying, or if you are doing something especially complex that we should know about. This is to know if perhaps there is a workflow that can be improved.

            Sorry to hear about, Rafael Gomes VFX.

             

            I haven't seen this before. Just to confirm, do you get this error while previewing or when trying to export? Does it happen with all the projects? What's the version of After Effects you're using? Also, what are your system specifications (CPU, GPU, RAM, OS version)?

            Let us know.

            Note: Moving this thread from Bugs to Discussions for troubleshooting.

             

            Thanks,

            Nishu
