I can't reply to Jin's post on the forum. When loading the thread, the hourglass appears with a Spanish writing ("Trabajando"); then when I go into the thread page it seems that I am no longer logged in and so it does not allow me to respond. Returning to the home page I find myself still logged in. I think there is still the problem with the translations plugin. @Phyllis: I put my answer here for Jin if you want to post it for me. There is also a note to change some names in Preferences --> performance I too, like fary54, think that what you need is the Src Only (Slip) trim. (@Phyllis: Perhaps there is confusion with the wording "Button 1-2-3." Perhaps it is better to replace it with LMB; RMB and MMB which stands for Left-Right-Middle Mouse Button) @Jin: I am not familiar with Kdenlive, and in your video (gap.mp4) I cannot interpret the havana color clip. The canvas, and therefore the gap, is blue; the previous and subsequent clips are black; the havana space is what? When you do trim on the edges of the two new black clips resulting from the cut (scissor) the havana spaces at the edges shrink. I don't understand what they represent...
