Different size settings for audio and video files

Hello!

I wish there would be a possibility for specifiying different widths and heights for audio and video files.

At the moment I have a complete video area (eg. 400x300) for audio files. In views it is taking to much space.
I didn't find a solution, how to set it up in the administration area.
Therefore I would like to have default values for audio files and for video files.

I am using CCK, Filefield and JQuery_Media at the moment.

Other tips (workarounds) in the meantime are welcome!

Best regards,

Christian
