Hello,

 

After AE crashed and I reopened it, some of the MP4 files in the project are not working. the error 86::1 says that 7 files are "damaged or unsupported" and it cannot be imported.

 

These files were working fine this morning, and I have not touched them. There are several dozen other mp4 files in the project that have no error. Please advise! I have to deliver this project TOMORROW!

 

Apologies for my frantic use of CAPS lock, but I am feeling very desperate.

 

Will

Can you play the problem files in another application?  Try Premiere Pro, or just a media player like VLC.  If not, they may be permananetly damaged.  Do you have a backup?

 

Do they import to Adobe Media Encoder?  Try exporting them in an intermediate format.

 

Try duplicating the files, move them to a different drive, and replace them in your project.  Any luck?

They do import to media encoder, and they play in every other program (VLC, premier, etc...). I shut the computer down and returned a few hours later, and the error had stopped. It is a big project, so perhaps it needed to rest.... But this is the second time that I've run into the issue. Is there any way to adjust my workflow so I can prevent it?

Also, try to import the corrupted footage in a new AE project to be sure if the issue comes from your footage or from the old project, and in all cases try to purge the RAM and disk cache
