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
Operating System
Windows 11
Steps to reproduce
I came to LosslessCut because of its reputation as a fast and convenient lossless video cutting tool. However, I found it very difficult to use for a simple precise trimming task.
I have a short video of about 5 seconds. I want to extract the segment from:
00:00:01.200 to 00:00:03.153
After multiple attempts, the exported file name correctly indicates the intended range, for example:
00.00.01.200-00.00.03.153
However, the actual exported result is not the requested segment. The output is either:
the full original 5-second video, or
an approximately 2-second clip, but with the wrong timing / shifted content.
This is very confusing because the output filename suggests that the correct range was selected, but the actual media content does not match that range.
Expected behavior
When I set the segment range to:
00:00:01.200 → 00:00:03.153
I expect the exported file to contain only that portion of the video, approximately 1.953 seconds long, matching the selected time range as closely as possible.
If frame-accurate or sub-second cutting is not possible in the current mode due to keyframe limitations, I would expect the application to clearly warn me before export, or provide an obvious option to re-encode / smart cut for accurate output.
Actual behavior
The output filename shows the intended segment range, but the exported video content does not match it.
Observed results include:
exported file is still the full original 5-second video;
exported file is around 2 seconds, but the content is shifted and does not correspond to 00:00:01.200-00:00:03.153.
Share log from developer tools
Open a short video file of approximately 5 seconds in LosslessCut.
Set the segment start time to 00:00:01.200.
Set the segment end time to 00:00:03.153.
Export the selected segment.
Check the exported file name and playback content.
