VS2020 How to join several movies into one without rendering?

[steve13]

I rendered some chapters of a movie and saved them as separate files.
Now I want to join them together in one file.
When I do it, VS2020 renders them for several hours encoding them again and lovering the overall uality of clips.
Is there a way to simply join already prepared clip files without re-encoding again?

To combine clips the only way is to render the project to a new video file.

I assume all your video clips are using the same properties, you do not give any details nor their duration.

1 / You should start a new project
2 / Add your clips to the top timeline should show a message to match project settings, yes to that
3 / Share, Top left of the options panel is an option for Same as Project Settings, a little greyed out so put a tick in the box
4 / Down arrow for Same as First Video Clip
This will render the clips to a new file using Smart Render, should be relatively fast in doing that
It will use the same settings as the original video and should retain the same quality.

There are video splicer programs available that will join together video files without any loss of quality caused by re-rendering. For example, MP4Joiner, will merge MP4 video files together.

Thank you for answers.
As suggested I used other program to join prepared clips.
I used BandiCut. Works fine and fast.
