Disabling overwrite still exports segments and does not save time on export

[SignpostMarv]

I have a lot of issues to go through, so in order to make it easier for me to help you, I ask that you please try these things first

• Try with the newest version from GitHub
• Read the documentation and FAQ, Known issues, Troubleshooting
• Search for your problem under Issues or Discussions
• If you have a problem only with a particular file (or file type), use this form instead
• Windows 7, 8 and 8.1 are no longer supported. This is not a question about Windows 8.1 or older.

Operating System

Windows 11

Steps to reproduce

1. Disable overwrite
2. Enable experimental cutting
3. Create many segments in a multi-hour video with at least one 2 hour segment
4. Export
5. Export again

Expected behavior

LosslessCut should zip through all the exports and effectively do nothing.

Actual behavior

LosslessCut exports the videos with filenames like 2023-08-22-smartcut-segment-copy-4.mp4 and promptly deletes them when done.

this problem is only related to the experimental smart cut feature, right?

will make a mental note to test without it, just felt it important to include that was part of the issue.

No, default export settings are enough to reproduce.

@snakecase this is because you're using "merge" export mode. This will delete all segments after merge is complete, thus the files cannot be reused. Then it will create a new random suffixed file xx-cut-merged-1693944979865.mp4.
If you instead choose Merge & separate it should reuse all the exported segments next time (but the merge operation will still be re-done because it wouldn't result in overwriting output). Or wasn't that what you wanted?

Got it, thanks.

closing for now, can reopen if still a problem
