Encode failed (error 3).

Anyone recognize this error and what can be done about it?

Answer 1

Errno -2

2 ENOENT No such file or directory. 
A component of a specified pathname did not exist, or the pathname was an empty string.

Source: http://www.freebsd.org/cgi/man.cgi?query=errno&sektion=2

In this case it meant:

• You did not type the right filename or file path, or
• you do not have permission to read from the file/path you typed.

Answer 2

Ended up being a permissions problem! It turned out I wasn't owner of the folder I was outputting to. The fix was something like

chown $USER folder

Answer 3

I had this same issue and was able to get passed the crashing by using "advanced settings" to try and slow things down.

It seems to be working

I'm not sure if what I've changed may negatively impact the video/audio quality (very novice ;-)
