Cross-Dissolve Time

Works for me in 16 as it did in 15, via click-drag of the mouse or via the Inspector. In some cases - you can't stretch a transition further if you don't have big enough 'handles' (i.e. spare frames available) at the divide on each clip. Try slipping or moving the clips over-one another a bit more.

Please detail OS and exact Resolve version
its working for me so
Take a phone video ray, of the two clips, show the handles on both by selecting the clip to trim, then place the transition on and show that length..

because you have no handles

[Peter Chamberlain]

On the edit page, in trim edit mode, click the first clip end point, a white box will display how much of the first clip extends into the space of the second clip.

no handle, no transition.. the longer the handle, the longer the transition can be.
Of course, the next clip needs handles too.

To expand on Peter's answer:

A cross dissolve can only span as many handles (or trimmed edges) of a clip as you can provide. It can be shorter than that length, but never longer.

If you bring a clip into the timeline as is, and try to add transitions in the edit page, it will ask you if you want to abort... or if you want to trim the clips further.

This is your screenshot, annotated to show the handles - notice that each clip has been trimmed to 12 frames?

If I were to remove the cross transition, the trims would be apparent - I will not see the last 12 frames of the first clip and vice versa.

If it is still not apparent, please take a look at this thread:

Post a link to two short clips and a two shot drp that shows the issue.

We don’t see the problem u have.
When ur able to share something we can check.

the video doesn't show what handles the clips have.

Are you absolutely sure you have more than enough overlap or handles on your media to allow a longer dissolve? You have not really answered this.

It seems that you are the only person seeing this issue. You still have not clearly shown the amount of overlap you have available on the clips at the transition point. It’s almost impossible to help without an extremely clear explanation of how much overlap you have available. Telling us you have enough does not show us how these clips have been edited. Can you give more info like the original full clip start and end timecode and the timecodes for the in and out point on the timeline? This will help us help you.

As a test, take 2 seconds off the end of the first clip. Then take 2 seconds off the front of the second clip. Then add your transition.

Dear Australian Image,

I also am in Australia.

Please send me a private message via the forum with your contact details and I will call you today (Thursday) and talk you through this issue.

I visited your website but found no contact details there.

One of the issues is that posters assume that I know all the terminology that applies to editing in Resolve (or other software), such as handles.

"Handles" are simply unused video that is after the end of a clip or before the beginning of a clip.
For example, if you have a 10 second piece of video and you add it to your timeline and then trim 2 seconds of video from the end of the clip, you have an 8 second clip on your timeline and there are 2 seconds of "handles" that you trimmed out that you can't see on the timeline but exists in the original clip.
In your earlier screenshot of the Cut page, in the top right corner where it shows your transition, the black and white frames before and after your edit point is the extra "handle" material that Resolve is seeing in your edit. In your case it was showing 12 frames of extra handle material (12 on the outgoing side+12 on the incoming side=24 frames = 1 second maximum total transition time.
When you add a transition it uses this extra "handle" material to create the transition since the two clips you are joining will overlap.
The length of this transition can only be as long as the amount of extra "handle" material that exists on either side of where the outgoing and incoming clips are. So if you want to create a 1 second transition half a second of extra "handle" material needs to exist after your edit point on both the outgoing clip and the incoming clip. If not enough exists on either side of the edit, you would need to trim more off the end of the outgoing clip or more off the start of the incoming clip.
