Many thanks for your feedback.
I'll make a note of it for the next time.

"I couldn't answer directly to your post "How to create a gap in a clip by splitting and trimming" because the button of your post "Add a comment" doesn't work for me?

Forum problem of different language SOLUTION that I have found.  When you can not answer or comment to a forum post, this has been known to work for me:

1) logout

2) change the selected language on the top black colored line to "English" (even if it already is)

3) login again

weird, that responding did not work in the original thread, anyway, thank you for the answer, but I guess I did not explain my motivation correctly. The point is to avoid dragging, because then you mess with the position of the video in the timeline, I would like to create the gap without moving the clips around, so that I do not lose the synchronization of the first and the second half of the clip in relation to another track; I know I could move the second clip around to get back in sync, but I would like to avoid that as its not always easy to do and is time consuming.

As you can see in my screencast, I was only trimming the edges, but I did not move the second clip anywhere. Is this possible in Cinelerra?

Kind regards,

Jin

So I'll answer you here.

I just made a little video that shows you how to do it.
I hope it answers your question.
Have a nice weekend.
