Change video metadata


Hello,

I have downloaded some videos that contain title metadata, which contains rubbish text.

This unfortunately causes vlc to display the title metadata when the video is played, instead of the file name. Would it be possible to make a script that either deletes the title metadata, or at least forces it to be the same as the current filename ?

The videos come in various extensions, most of them are wmv.

Thanks.

if you're wanting to remove the text file that is presumably muxed into the file. I recommend MKVToolnix. It will list the individual parts of the file Audio, Video, Subtitles, etc, and let you choose what you want re-muxed. This creates a MKV video file, which plays nicely on VLC. If you need other formats, Avidemux is a good option. It's just not as fast and easy as MKVToolnix.

i had a quick look at my distros repos, all metadata utilities i can see are for audio only...

however, i know that ffmpeg/avconv can do what you want.

Hi,

thanks for the answers. I have indeed heard of the various tools that you mention (avonc, ffmeg, mkvtoolnix, avidemux, ...), but I'm not a tech expert, so I really don't know how to use them.
More precisely, how is it that I could use these to achieve what I want, which is to programmatically (through a script) change all the videos to remove the metadata ?

thanks.

^ if exiftools works on video, that would be really cool.
better, even.
there'd be graphical frontends for that, too, i think.

try this:
Code:
ffmpeg -i "some track.mp3" -c copy -map_metadata -1 "some track no meta.mp3"
this simply removes the metadata - all media players i know of then default to the file name, so there's no point in setting the metadata to "some track".
it also copies the track; you then have to remove the old track.
it is possible that your system uses "avconv" instead of "ffmpeg", but you can use the same command, just replace "ffmpeg" with "avconv".
if it works for you we can automate it into a script.

I think you may have typo'ed mp3 he's working with wmv windows movie format

command line
Code:
  [ user >$exiftool -Title="what ever you want" filename.ext
script or command line
Code:
for i in path ; do exiftool -Title="${i.*}" "$i"    done
that should add just the title of the file name to the title tag in the file, might need to fiddle with it a bit. the percent sign keeps getting removed out of code. it's {i(percent sign).*}
