The excact quality as the video file, how?

Hey. i was wondering how and what settings in the export category you have to chose to get the EXCACT same quality the video you have downloaded? i download episodes and edit them and would like them to be the same quality. it would mean alot if you could help me. thx

You can’t direct stream copy/export from Shotcut after an edit. There will always be decompression then re-compression.

How do I cut or trim a clip without encoding or transcoding it?
This is not supported, and there are currently no plans to support it. We recommend that you use VirtualDub or Avidemux for that.
