when i'm making a movie for a long time it appears on the screen, error opening movie output file, what do i do?

maybe the movie file itself is corrupted, did you record or stop it correctly ?

this error appears when I'm making the movie

What version are you using?

2.2.3

Are your display adapter drivers up to date? Driverbooster is a good tool to get all your drivers updated. Note: Always create a windows recovery point before updating your system. Could also be a codec issue. Try installing "K-Lite Codec Pack 15.6.9". Again, do all of this at your own risk.

you may have to download K-Lite Codec Pack 15.6.8 first, if you don't already have Version 15.0 installed.

Ok
