Error after Cron

HEy, I read many tutorials and howto´s, but found no solution.
I get the this error message, when running the cron-job. There ist no video in the trancoded folder an nothing in the temp. Only the original video in the
original folder.
It has something to do with the "ffmpeg2pass-0.log: Permission denied" But what is the reason for the error message?

export MALLOC_CHECK_=1; time ffmpeg -v 0 -y -i 'files/videos/original/video.mov' -vcodec libx264 -b 320k -r 24 -g 48 -s 320x256 -acodec libfaac -ab 64k -ac 2 -ar 44100 -pass 1 files/videos/temp/5-pre.mp4 2>&1 malloc: using debugging hooks FFmpeg version SVN-r15741, Copyright (c) 2000-2008 Fabrice Bellard, et al. configuration: --prefix=/usr --enable-static --enable-shared --enable-gpl --enable-postproc --enable-swscale --enable-pthreads --enable-libamr-nb --enable-libamr-wb --enable-libfaac --enable-libfaad --enable-libmp3lame --enable-libx264 --disable-ffserver --disable-ffplay --disable-debug --disable-network --enable-nonfree --enable-avfilter --enable-avfilter-lavf --disable-devices --disable-vhook libavutil 49.12. 0 / 49.12. 0 libavcodec 52. 1. 0 / 52. 1. 0 libavformat 52.23. 1 / 52.23. 1 libavdevice 52. 1. 0 / 52. 1. 0 libavfilter 0. 1. 0 / 0. 1. 0 libswscale 0. 6. 1 / 0. 6. 1 libpostproc 51. 2. 0 / 51. 2. 0 built on Oct 29 2008 18:49:56, gcc: 4.1.2 20061115 (prerelease) (SUSE Linux) ffmpeg2pass-0.log: Permission denied FULL PATHC /srv/www/vhosts/xxxxx/xxxxx
