Possible 3.68.0 regression: Exports entire vid, no cuts #2780
Description
The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first
- Try with the newest version from GitHub (also it might have already been fixed in latest nightly build)
- Read the documentation and FAQ, Known issues, Troubleshooting
- Search for your problem under Issues or Discussions
- This problem happens with all kinds of files that I try. For problem only with a particular file or type, use this other form instead
Operating System
Windows 11
Steps to reproduce
it worked one time it no longer Cuts anything. it exports the entire video at lesser quality which resulted in lesser megabyte video file, there is no smart cut option at all so that fix is impossible to do
Expected behavior
when I said the designated start and end where it would "cut it" I would have the video file I just edited
Actual behavior
I set where I want the video to be cut. it does not cut it at all. after exporting it, it spits out the entire file no edits no cuts just like the original I put in. for example, i put the full vid in, and the full vid come out

Yes... I also have an audio in mkv format and the cutting only happens at the end of the file, i trimmed a little bit at the start and a little at the end, but in the exported file only the cut at the end is missing the start is same as source file even though it should have cut like 5 seconds

Hi, which version of LosslessCut does it not work and in which version does it work (with the exact same file)?
del3bcl3 commentedon Feb 27, 2026
The lattest update and the one before the lattest update
mifi commentedon Feb 27, 2026
So 3.67.2 works but 3.68.0 does not (with the same files)? I cannot reproduce the problem. Can you please provide a sample file that reproduces the problem and which cuts you're trying to do?

@Lord8877kk from your timeline it looks like your files has no keyframes in it. This is likely to be the cause. Without keyframes it's not possible to losslessly cut. Maybe you can adjust the settings in your recording application so that it produces files with more keyframes.

i use obs as well

I'm wondering if it's a regression in losslesscut or it's OBS studio that has changed something when it comes to keyframes recently.
@del3bcl3 I don't see any cuts in your screenshot. You have simply one long segment that covers the whole timeline. In this case, it is expected that the whole video gets exported with no cuts.
improvements

next nightly will show a warning if trying to cut when there are too few keyframes
del3bcl3 commentedon Mar 9, 2026
Ill try it. Tho I'm not sure why I can't just cut anywhere in a video and have it start at that cut point and end at the cut point I want. But it has to be a certain place in the video?
Is there certain settings that need to be turned on in OBS for more keyframes to be generated I don't know nothing about keyframes?
I'm just trying to find something better than clipchamp because clipchamp sucks. It reduces the quality in my videos.

See documentation and troubleshooting to learn why you cannot cut anywhere you want.
probably lower keyframe interval
mifi commentedon Oct 18, 2026
closing since this is caused by too few keyframes in the file, not a bug. 3.69.0 now shows a warning when you try to cut with too few keyframes around the cutpoint

Thanks for your efforts :))
