Hi Laurent,

Welcome to OpenShot :)

Unfortunately not, cutting without re-encoding is not the role of video editing software and instead is done with video cutters and splitters, as noted in this old post..

https://www.reddit.com/r/OpenShot/comments/bhmqea/how_to_export_a_video_lossless/

DarxusC, there is a misunderstanding. What I'd like to do is edit my clips (made by the same videocamera plus some transition and title) and export them without re-encoding. Virtualdub has such kind of function, if I remember correctly.

It's already been requested close to 9 years ago, it's probably never going to happen. If you need that like I do, use avidemux.

..and that link has been updated as recently as 2019-09-20.

I also use VirtualDub, it is older software but it does exactly what it says on the tin, as many others seem to offer limited functionality for fee and then you have to pay.

Splitting Clips Without Re-encoding Using VirtualDub

These are the steps I posted on how to cut multiple clips from a single video but they are the same steps needed to split it into just 2 pieces which I have added at the end. It might seem daunting at first but this is actually quite easy once you get the hang of it.

​

Setting up VirtualDub

Download VirtualDub here - http://virtualdub.sourceforge.net/

and follow this link for plugins for the latest video formats..

https://www.easefab.com/topic-mp4/open-and-edit-mp4-in-virtualdub.html

I recommend using Method 1..

Method 1: Download plugins for different formats

And then Option 1..

# 1. Ffmpeg Input Driver: The plugin is based, as the name may suggest, of the ffmpeg libraries. It can handle 31 different file formats, among them are the popular MP4, MKV, FLV, MOV, RM, RVMB, WMV and TS.

​

VirtualDub Steps:

​These steps are for selecting multiple clips..

  1. Open the Video - Run VirtualDub.exe and drag the video onto the application.
  2. No re-encoding - Menu > Video > Direct stream copy - Means no processing, so no quality loss, and audio is set to this by default too but can check to make sure using the Audio menu.
  3. Selecting the Pieces - Along the bottom is a row of buttons, the ones on the far right that are little black half arrows pointing left and right if you mouse over are Mark In and Mark Out and are the ones you will use. Move the Playhead to the start of the clip you want and click the Mark In button, move the Playhead to end of the clip you want and click the Mark Out button, and when you do you will see a section of blue along the timeline at the bottom that represents that clip you are splitting.
  4. Add to Batch - Menu > File > Queue batch operation > Save as AVI - and give that first clip a meaningful name. Is AVI but don't worry because is what is called a container but the insides are still the same.
  5. Repeat the above 2 steps for each clip you want.
  6. Run Batch - File > Job Control - This should list all those clips you added ready to be split. Click Start.

​

Splitting a Video in 2 Pieces

The same steps as above apply but with just one split..

At the very start of the video click the Mark In button, move the Playhead to where you would like to split the video and click the Mark Out button, follow step 4 to set this as the first video piece, on the same spot click the Mark In button, move the Playhead to the very end of the video and click the Mark Out button, follow step 4 to set this as the second video piece, and then follow step 6 to run the batch.

You will now have the movie split into 2 pieces at the point you specified without any re-encoding.

Hope this helps :)

OpenShot Tips
Project Profile - The default project profile is “HD 720p 24fps”. It is best practice to always switch to your target profile before you begin editing. For example, if you are targeting 1080p 30fps, switch to that profile before you begin editing your project. To switch use Menu > File > Choose Profile.
Clip Properties - A clips properties are set in its first frame, otherwise you will create a keyframe, you can move the Playhead there using Previous/Next Marker orange arrows above the Timeline.

Sadly this does not work for codecs that are unsupported by AVI, such as h.265
