Offset vs Shift - usage in LosslessCut

[slrslr]

Hello, LosslessCut has offset and shift function. What is the difference between two in layman terms?

AI claims:

Offset: This is like rewinding or fast-forwarding the entire timeline. It shifts the start point of the video relative to the original file. If you set an offset of +5 seconds, the video starts 5 seconds later than the original, effectively cutting off the beginning. It changes when the video starts playing.

Shift: This usually refers to moving a specific segment (like a clip you selected) forward or backward in time within the project timeline without changing its duration. It's used to align a clip with another one or fix synchronization issues (like audio lagging behind video).

Summary:

Offset = Changing the start time of the whole file (trimming the head).
Shift = Moving a specific piece of the video left or right on the timeline.

So offset should be about trimming+moving on the timeline and shift about moving on the timeline?

Hi, which offset function are you referring to exactly?

[slrslr]

When you search for "offset" in https://hosted.weblate.org/browse/losslesscut/losslesscut/ you may be able to see several strings like:

Auto load timecode from file as an offset in the timeline
Instead of video apparently starting at 0, you can offset by a specified value.
Set custom start offset/timecode
Set custom start time offset

Ah, this is just a visual thing. Doesn’t affect exported files at all, just the UI
