Hi. After playing (a lot) with Lossless Cut, I think that the possibility to export only one segment would be nice (when you have defined many). It could be implemented with a right-click menu action, for instance?

Hi. Why do you need to have many segments but only export one?

One case would be that you want to change the size or the cutting mode of only one of them. You can do the full export again, but it takes more time and you overwrite everything (unless you move the existing export).
I agree this is just a "nice to have" feature, but it seems quite natural to me (and I was almost surprised that it didn't exist, in fact...).

The overwrite shouldn't happen (anymore) iirc, the current unix timestamp in milliseconds will be added to the exported filename when you click Export+merge.


So as a current workaround after making multiple segments you could:

  1. Save the project with all created segments as a CSV
  2. Remove the unwanted segments from the Segments to export list
  3. Click Export button to only export the single required segment
    3.1 Optionally rename the created file by clicking 'Show' to open the folder in your file manager
  4. Load the previous project CSV from step 1 to restore list of previously created segments

As suggested by @bouscram adding the possibility for a 'right click action' to the Segments to export would be nice.

Additionally more options in a menu with more export and playback options of single segments could be useful; to only output that single segment as a file, start from the exact in point and pause after playback, opening renaming dialog from the menu, removal or moving a segment up or down in the list etc.

Hi. Why do you need to have many segments but only export one?

This would be very useful to reduce export time and disk writes when we need to adjust imprecise cutpoints.

Let say we need to extract 4 segments of in total 2GB from a video file of 3GB, we would have to export 4 times that take 40 seconds for 8GB in total. And this is for case when it takes 1 edit to get the desired cutpoint, while in reality one may take 3 or 4 times for editing a single segment.

If it there's an easy way (say 1 or 2 click instead of the complex process suggested by @Wiethoofd), we still have to export 4 times for adjusting the cutpoints but it takes only a quarter of time and disk write.

Have now implemented an export single button on the export summary page to only export the currently selected segment.

@mifi Nice to have, I suggest though to change the wording to be more clear since "Segment" is the language used and more obvious to related to, e.g. "Export segment", "Export selected segment" , "export single segment",(or a segment # selection :D ).

Also Seeing that screen first time I was slightly surprised and unsure.... even forgot that these are buttons just like in the app (despite previously having been used to clicking buttons in the app). Perhaps change wording/include "Export...." "settings", "options" or "configuration". The fact it says "summary" lead me to think I only can click the blue buttons to confirm.
