how to shorten several clips at the same time or extend

hello,

I would like to shorten several clips at the same time or extend.
After I have selected my clips, I go to the beginning or the end of the group
to change all the clips at the same time.
Unfortunately, all clips are deselected and I can only change one clip at a time.

How can I change all selected clips at the same time?

Thank You

Page 554 of the user manual will explain how it works.

Yes, i´m sitting in front of the manual, but don´t understand what to do.

could you please explain?

1
Choose Selection mode, and select the edit points or clips you want to trim. To make multiple selections, click once to select the first item, then Command-click each subsequent item you want to add to the selection. You can select as many clips and/or edit points on as many tracks as you like.

2
To ripple, slip, or slide the entire selection at once, choose Trim mode.
To resize or move each selected item at once, continue using Selection mode.

3
Use the mouse, keyboard shortcuts, or timecode entry to execute the trimming operation, just as you would if a single edit point or clip were selected.


I follow exactly the instruction.
Moving the selected clips works. Unfortunately, size changes are not.
I can only change the length of the selected clips together if I first combine the clips with Ctrl-Alt-L into a group.

Where is my mistake?

Are you in the Edit tab ? I noticed yesterday I couldn't do that in the Fairlight tab, if I remember well...

Yes,
i´m in the Edit Tab.

Any other NLE does it...

selecting clips,
going to the beginning or end of the group,
pulling or pushing
and ready.

Can´t figure it out.

It´s so annoying.

works for me as per the instructions, when selecting edit points to resize clips

Not true, try to do it in avid...

This works every time for me.

Make sure the tracks are not locked and that they are chosen:

1 - hit "T" for trim mode.

2 - Draw a box with the mouse around all the clips you want to trim or extend. Use ctrl-left mouse button to select non-contiguous groups, if necessary.

3- hit "u" until you highlight the side of the transition you want to trim or extend.

4 -if you want to ripple trim or ripple extend the clips, proceed with the trim.

5 - If you don't want to ripple the changes, hit "a" before you begin the trim.

Sorry, doesn´t work for me.
I give up.
I am probably too stupid,
or should blackmagic quickly find a practical solution.
it can not be in the sense of the inventor that a
standard function is so cumbersome to perform?

Check one more thing.
Make sure the cruiser is changing to this:

Before right clicking.

That what i want to do, only works, if i link all clips b< CTRL-ALT-L, before rezising.
When the clips are linked, i can go to the beginning or the end
of the clips-group and change length of all clips in one step.
even if the selected clips directly to another group,
I can change the length without ripple effect.

Hmmm... I've tried now that I'm in Resolve....
It's true it isn't intuitive (at all). Where in FCP7 I could do it soooo quickly, I realized that I had to : select Dynamic Trim Mode (w) > select the last frames only (see attachment) > it works

Funny I wasn't in the situation to do it for years until I saw this thread
So you're right, it's not handy at all since gross selecting the clips and trim them all at once shouldn't require any other action, I admit...

As with any NLE, you have tell the system which clips you want to trim.... You can do this by ctrl-clicking transitions, one after the other, or doing it as I suggested above.

Dynamic trimming will work after multiple transitions have been selected, but it's not a requirement for trimming multiple clips in one operation.

Sorry, but this sounds like a case of collective user error.

John, excuse me, but I expected to only have to roughly select all the desired tracks and trim them all... That's what I've been doing for ages, no user error involved here; so I now understand the OP thing...

Your illustration is a trim at one vertical cut point (which is easy to do, various ways). As I understood the OP, he wants to trim multiple clips at various positions in the timeline, with one trim action, which is also relatively easy to do.

In any case, I give up on this one.

I read your suggestion and it's ok... But anyway, it involves much more actions than normally requested, that's my point. Even in the OP example (no vertical point), roughly selecting or cmd/ctrl + select all the clips should be the maximum to do before being able to really trim. Highlighting the transition shouldn't be required, that's potentially what's at stake...

I've read this entire thread and having the same issue!

Here is the example of what I'm trying to do perfectly illustrated:
youtu.be/1asUj3POfOg?t=131

After selecting a group of images for a slide show I wish to adjust the interval for ALL clips, but as soon as I click on a single clip the selection disappears and I'm left to adjust the clip I'm touching. . .

Can anyone tell me what I'm doing wrong?
I've tried all of the suggestions in the above thread and I've still not located my problem.
If I choose the middle clip and hold the "Y" button I can MOVE all clips together, but if I try to Trim Edit (or any other edit) it de-selects the group

Perhaps I should mention that I have a controller attached? (Speed Editor)

I tried the desperation move of combining all clips in a group and changing the speed . . . but . . . this is not what I want to do and it's been demonstrated in the video so I just need to figure out what I'm doing wrong

This feature seems to have been removed in version 17, Josh. Not sure if that's by design or a bug. But for now, it's one at a time.

Have you tried selecting all the clips, switching to Trim Edit Mode, then hitting Ctrl-D to change the duration?

I suppose the good news is I was going MAD thinking it was user error . . .
The bad news is . . . they have crippled the program . . .

Thank you for offering this work around, but dear lord, no that won't do unfortunately
The purpose is to time the collective slide length to match the music track.
(I have over 20 photos in a slideshow, to 'guess' the correct interval . . .
I suppose I'll have to do math with your work around method as guessing is out of the question)
This is a trivial procedure in ANY OTHER NLE . . . accept Davinci Resolve after this neutering of function.
Why Black Magic, Why!?

The youtube video was released 10/12/20 so a late version 16 build.
I can only see 2 potential solutions:

1) petition BMD to fix/ bring back sanity on the timeline (send an email to support?)
2) roll back to Resolve 16 (or possibly v17 Beta)

I'm currently running Resolve on my Macbook, is it as simple as installing a 2nd program on the Mac, or should I just try to search for an old installation file to use on my PC?

I think I have a solution, on version 17, by using Nudge.

1. Enable Trim Mode (T).
2. Box-select your clips (hold Ctrl to select multiple times)
3. Press U to select the side of the cut you need (or click Trim>Edit Point Type)
4. Press , or . (the comma and period keys) to move the edge by 1 frame left or right. (Trim>Nudge)
5. Press Shift+, or Shift+. to move by 5 frames. This is Fast Nudge. You can change the amount of frames in settings: DaVinci Resolve>Preferences>User>Editing>Default fast nudge length.

I had 70 clips of different length that I needed to extend by 1 second in each direction. This worked for me. And it looks like you can shorten them too.

There are other topics that cover this issue.
I made a short video to explain how it works in Resolve 17.

I have the exact same problem, and so far have not found a workaround. I thought that the 17.4 upgrade would have solved it, but that's not happened for me. Anyone else have this problem? I see that the short video that Peter Cave placed here works for him, but again, not on my system. It's sending me crazy trying to link the clips and guessing the length to go to!
Blackmagic, when are you going to recognize the problem and sort it out for us mortals?
