I miss this feature also. Have to use Avidemux because of this, although
otherwise I'd rather use OpenShot because it can have multiple tracks
where avidemux cannot and overall video editing with avidemux is very
limited.

As it was said above, it should be as in avidemux, so one could choose
"copy" for audio andor video codec separately.

And why not also "null" as a video or audio codec, to easily separate
the audio track from the video to have it externally editable in
Audacity (NR and other complicated audio filters). Then just join the
improved audio back.

(In Mplayer there also was special codecs "null" and "copy" always
available and useful: -ovc copy -oac copy)

2nd best solution:
Even just copying the original audio+video codecs' parameters and use them to re-encode would be better than now when one must spend time figuring out the parameters in the original video and then try to find as close output parameters as possible. eg.: No point of re-encoding 320x240 video to PAL or 14400 bps audio to 24000 bps.

(Also ability to use filters in avidemux when transcoding is something
which Openshot is missing. But of course if copy codec is supported, eg.
audio track can be filtered externally by Audacity.)

Title:
  Allow export without re-encoding

Status in OpenShot Video Editor:
  Triaged

Bug description:
  This is not a bug, it's a suggestion

  Yesterday I have discovered very occasional your programme and have tested.
  Congratulations, it works wonderfull, but I have a suggestion.
  I miss the copy function in video part as in audio part.
  I will explain it you:
  When I have exported a video in a certain codec, and I want still somewhere cutting a piece , then I must re-encoding the video completely.
  When there must be a copy function, I can copy the video and audio without de cut piece, that saves much time.
