AE won't read some files anymore

Hi

I had installed codecs so I can import .mkv files by renaming them in .avi.

That worked fine for a long while.
And now, suddenly, they won't play anymore. I can import them, manipulate them, but they won't preview nor render. When I try, AE hangs up for a while then does nothing. Preview remains black. Same with Media encoder.
I tried reinstalling the codecs or AE, to no avail.

Anyone had the same issue?

Without any detailed system info and the relevant info from your media system control panel/ the device manger on the CoDecs we can't really tell you anything. DirectDraw-based CoDecs have never worked well with AE and simple changes in your systems graphics hardware by installing a newer driver for instance can mess up the whole thing. It's beyond AE and doesn't really have anything to do with it. it simply relies on this to be handled at the system level, so the issue is somewhere there.

Thanks for the answer.

It worked perfectly fine until recently, and it seems to be a common method that works for most users so idk...
Can you specify what infos you need please?

Hi b75,

Thanks for writing in.

MKV is not supported by After Effects. Changing the extension is a great quick tip, however, it's not the recommended workflow. I'd suggest transcoding the clips to codec supported by After Effects.

Hope it helps.

Thanks,

Nishu
