Impossible to edit, problem preview

[matthieur54433542]

Hello,

This morning, the preview doesn't works. I uninstalled and reinstalled the software but it's the same and I restored the old driver of my graphics card, but the problem persists.

And when I tried to close the program does not respond anymore.

How can I fixe it ? I have to give back videos to my clients quickly...

Did you just allow an operating system update?

Maybe, I think. I don't really remember.

What video file format are you editing? (video format details like a codec and file extension)

[Byron Cortez · Accepted solution]

Codecs supported by After Effects, Media Encoder, and Premiere Pro since the last version. Dropped support for QuickTime 7 era formats and codecs 

Your video codec it's not supported, you have to downgrade Premiere Pro or transcode your video with an external application like HandBrake.
