I’d also like to vote for a feature like this. Select some clips and right click → something something transition similar to the slideshow function but in-place.
You can use the slideshow generator with video files as well to make this. Except it is not bulk adjustable with redoing it. I doubt that will ever happen.
This is great, so a lot of code can be easily reused. What I want is different insofar that my clips are cut and modified in shotcut, I do not have them as finished video files that I could concatenate. Doing that limits too much of my flexibility.
That already works with Slideshow Generator. You can trim playlist items. You can have multiple playlist items from the same source in the playlist, sometimes called sub-clips. These are basic concepts in Shotcut. Slideshow Generator respects all of that.
Update: while testing this just now with sub-clips in playlist, I see it does not respect the out points of the videos. I fixed that for the next version.
I tried it with Slideshow Generator, you can not use it with the timeline, this is playlist only. I never use the playlist, I always drag and drop into the timeline. Also, please reread my main post, this is about something different than what sg does.
Your explanation makes me think you did not try the Slideshow Generator or maybe you did not think about how you would need to change your workflow.
I wrote the slideshow generator with this exact use case in mind. But you do have to change the way you think about your workflow.
First, you stage your clips in the playlist
Then, create a new track for the clips and transitions to live in
Next, you generate the slideshow into the empty track
Preview the result. If you want to change something, you delete all the contents of the track and regenerate the slideshow again - changing a parameter if desired.
What you have suggested will likely never happen, which is why we suggested what is available today (plus the improvement for next version or tomorrow’s build).
P.S. you can copy a clip from timeline and paste it into the playlist. But another workflow is to add a bunch to playlist and double click each to trim in the Source player.
Given that most of the code is already there but only needs to be tailored to accept clips from the timeline for them to stay in place and is reversible, there is no good reason this shouldn’t happen.
This has a big demand. Thinking about the other parts of the road map, this is not a niche topic that only one person wants and assumes many needed.
Your tool is a one way ticket to a slideshow from playlist items. It is only for those that want a slideshow and who know they want a slideshow from the start and who do not want to modify anything. Accept that your tool does not do what we want.
I think there are actually two different but related enhancement requests here: crosshatching across multiple selected clips and the application of a filter or filters across several selected clips. I believe the second is a trivial change which I would happily do myself were this an Open Source project. The first is a little more complicated. I see the workflow like this. You crosshatch two clips, right-click on the crosshatch and a pulldown menu appears that offers you the opportunity to apply the crosshatch across multiple clips. Select that option and a dialog window pops up requesting you to select three or more clips. You do that then click OK on the dialog.
