I'm putting together a slide show and just found out I need to increase the duration each image is displayed from 4 to 6 seconds. I've spent a lot of time cropping and color-correcting each image, so I'd really like to do this without starting over.

I've seen several people show how easy it is to reduce the duration of the stills (Select All, right-click to Change Clip Duration, then Delete Gaps). Is there any way to similarly increase the duration of each slide? Change Clip Duration "works", but 2 seconds of each new 6 second clip is overwritten by the expanded adjacent clip, so only one clip actually becomes 6 seconds, the rest stay at 4.

Any other ideas?

Cheers,

Select trim tool (T). Zoom out timeline (Shift Z). Drag select all cuts. Hit U twice. Comma or shift-comma to nudge trim clips to lengthen them (period to shorten). Make sure track targetting is active before doing this.

Thanks, but the instructions seem to fail at the "Hit U twice" point. I'm not seeing anything change on the timeline (expecting something like this:

).

But I'm not sure how to "Make sure track targetting is active before doing this" - that could be where I'm going wrong.

Try this:

Thanks, but unfortunately that's not working for me either. I follow your steps and up through selecting all the clips, but when I go to adjust, all the clips get deselected except for the one the tool is touching.

Also, I have still images I'm trying to make longer, but your example is video clips, and (probably because it's video clips) I only see the clips getting shorter.

I'm about to give up and just render it at the existing 4s/clip, then stretch the rendered video by 50% and re-render. Not ideal but should work well enough...

Try this thread and see if it helps.

That did it! At least one of the problems was that all the clips I was trying to lengthen were not the same length initially. Once I selected only clips with the same length, it worked like a charm.

Thanks!

The clips do not have to be the same length. Without seeing what you are doing it's hard to tell what your issue is. I would guess that you were including the beginning of the first clip at the start of the timeline which cannot be moved to the left as there is no timeline there for it to move to. If the green highlight gets deselected then you may have changed from the trim tool back to the selection tool.
