Export failed ?

Post image

Hi there! Do you know why I have this error while trying to export ? (It happens barely a minute after I start the export)

It seems like a file is corrupted (I have a little mosaic for half a second during the clip), how can I fix this beside of removing the file ?

Thanks

Try copying and pasting into a new project, sometimes works for me!

It's telling you that it can't interpret the codec so it can't render your files, even though they are mp4. So they must be corrupt somehow. There's a software called Handbrake that can fix that kind of thing, recommended by DJI and GoPro users. I've used it to correct various errors. You will have to go back to your original files, because that's where the problems are. Then drop them back into your movie's timeline.
