[Paul Bußmann <508975@xxxxxxxxxxxxxxxxxx>]

I'd like to put my Video Disk Recorder streams (.trp) into a new
container (.mkv), trim it at front at end and remove commercial breaks.
Doing so OpenShot currently re-encodes the complete footage although it
could direct stream copy from the .trp-file to the .mkv file. This is
why I currently use ffmpeg to first demux the channels, OpenShot to get
the exact timestamps of the cuts and mkvmerge to create a bunch of
files. :(

As an idea for how to integrate the functionality in the UI, it would be
very nice if one could chose "keep" (in the dropdown chooser with "Low",
"Medium", "High") at the quality selection in the basic settings tab of
the project export dialog (I'm not aware of the english dialogs, I use
it in german). Selecting "keep" can then automatically set the video
profile to the same as the footage. The container (e.g. mkv, avi, etc.)
is determined by the export file's name.

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.
