How delete characters of specific line with sed?

Hi,

I have a text file with some lines like this:

Code:
/MEDIA/DISK1/23568742.MOV
/MEDIA/DISK1/87456321.AVI
/MEDIA/DISK2/PART1/45753131.AVI
/IMPORT/44452.WAV
...

I want to remove the last 12 characters in each line that it ends "AVI". Should look like this:


Code:
/MEDIA/DISK1/23568742.MOV
/MEDIA/DISK1/
/MEDIA/DISK2/PART1/
/IMPORT/44452.WAV
...

Does anyone know how to do it with sed?

Thank you,

Iņaki

NAME
ogmdemux - Extract streams from OGG/OGM files into separate files SYNOPSIS
ogmdemux [options] inname DESCRIPTION
This program extracts all or only some streams from an OGM and writes them to separate files. inname Use 'inname' as the source. -o, --output out Use 'out' as the base for destination file names. '-v1', '-v2', '-a1', '-t1'... will be appended to this name. Default: use 'inname'. -a, --astream n Extract specified audio stream. Can be used more than once. Default: extract all streams. -d, --vstream n Extract specified video stream. Can be used more than once. Default: extract all streams. -t, --tstream n Extract specified text stream. Can be used more than once. Default: extract all streams. -na, --noaudio Don't extract any audio streams. -nv, --novideo Don't extract any video streams. -nt, --notext Don't extract any text streams. Default: extract all streams. -r, --raw Extract the raw streams only. Default: extract to useful formats (AVI, WAV, OGG, SRT...). -v, --verbose Increase verbosity. -h, --help Show this help. -V, --version Show version number. NOTES
What works: * Extraction of the following formats is fully supported including writing the stream contents to useful container formats: video -> AVI Vorbis -> OGG/Vorbis PCM -> WAV text -> text files (SRT subtitle format) * All other audio streams (MP3, AC3) are just copied 1:1 into output files. MP3 and AC3 files should be usable. Others might not. What not works: * Headers created by older OggDS (DirectShow) filter versions are not supported (and probably never will be). AUTHOR
