I get an error when trying to convert video

You're doing a two pass encoding, but you haven't made a first pass yet (which would have created the log file). Besides, you're using some options which are ambiguous.
If you don't need a specific target file size, a two pass encode is unnecessary.
Try this:
ffmpeg -i 10.mp4 -c:v mpeg4 -vtag xvid -qscale:v 3 -c:a libmp3lame -b:a 128k -vf scale=640:360 10.avi
-qscale:v 3
specifies the desired video quality, 1 would be very high quality / big file size, 31 the lowest quality / small file size
For a 2 pass encoding, see the example in the ffmpeg wiki.
