When exporting the timeline, often is needed to respect the original conditions of audio and video.

Accessing the "personalized" quality tab, it would be great to can select the Width x Height detected from a clip in the project, and optionally the same for the audio quality and codecs used to export.

That parameters don't have necessary to coincide with the standards (320x240, 640x480, 720x576,...) and the bitrates too.
