Hi everybody, before to do this post? I searched for previous posts but I noticed that their cases are different. in mine happens that the software isn’t creating proxies for all the PNG files uploaded, although the settings indicates that it does, also shotcut isn’t saving completely all the .mlt files in the directory set up,plus sometimes the software crashes or hang up while connected to internet ( that’s why I was using the software offline). I had installed V25.01.25, thinking that maybe the software was asking for update, I extracted in the pendrive V25.03.29 and ran the software, forgot to delete all the meltytech and shotcut files in the laptop.and…now shotcut crashes when I tried to upload files in bulk at the playlist.Any recomendation will highly appreciated,
It is not supposed to. Read the documentation.
shotcut isn’t saving completely all the .mlt files in the directory set up,
It is not supposed to. It saves it where you tell it to. Unless “the directory set up” is the place you navigated to in the file save dialog, I do not believe you.
sometimes the software crashes or hang up while connected to internet
It has nothing to do with an Internet connection unless perhaps using files on a cloud drive.
now shotcut crashes when I tried to upload files in bulk at the playlist
Try fewer files. Try using the new Files panel instead of mirroring your folders into Playlist, which is not necessary.
and…what about why isn’t saving the mlt files? or crashing when I use internet?
I understand your point already Leader, I’ll look for the screen recorder and…definitely will do as I should from the beginning , thank you anyway for your immediate response, it’s highly appreciated.
What exactly happens when internet is on, I don’t buy it either, shotcut has nothing to do with.
Alternatively try this:-
Ar_D Happens that this is the second crash in less than 3 months, and my mistake was that I didn’t deleted the shotcut entries on the registry, so in order to avoid that? again! I deleted Shotcut absolutely from the registry already and will extract back shotcut V25.01.25 on the pendrive ( also left a reference on how to delete shotcut from the registry on the previous topic, if …someday I forgot how to, because sometimes people don’t even remember their names 
) if someting happens now? surely I’ll let you all know about it, Good thing that yo’all don’t even listen what I scream when things don’t work as they should
I don’t why it happens to you, but I have never touched the registery editor since I used shotcut for the first time and it work butter for me (in terms normal usage, not the obvious bugs or crashes). Although the FAQ says to delete the registery files so I am not going to tackle that.
Good luck mate 
Actually, try a windows to go installation on your pendrive through Rufus. And try to install and uninstall shotcut there several times, and see if it still works there. Idk why I am recommending this, but I think you current install of windows can also be a problem. Idk if it’s actually but I do suspect it.
The issue my friend, is…just couple hours previously to that? everything was, perfectly fine. last night, I just deleted shotcut from the registry, extracted on the pendrive V25.01.25, and when started to work with the slideshow of PNG’s and video clips, now not only not create proxys for some PNG’s, but isn’t playing the clips completely on the preview slideshow, I played back the clips alone one by one, and it plays back fine. But when I click “add to slideshow”? the preview don’t reflect that playback the clip completely, just the begin and jumps to the next PNG 
. I’ll show you a video in a couple hours. now that I recall? should I have extracted V25.03.29 instead? do V25.01.25 will be forgotten? now that V25.04 Beta is on the road for may-2025?
This exactly sounds like laggy playback to me… I will wait for what you’re exactly facing freind.
Hi , As promised, my kid can’t finish his school project because of it. here’s the explanation of the video. look at the proxies panel , there’s 3PNG’s #1,#2,#4.(video #3 & #5) And there’s proxy for just#4. And for slideshow of PNG’s + Video clips, shotcut just play the intro of the clip, but?..when I played Back each clip alone?, it played OK what’s going on?
the weird thing is…I already have made like 12 slideshows for all his cousins, and crash until now!
Please comments!
That is by design as it is a Slideshow Generator, not an automatic editor. Read the slideshow dialog. It says Clip duration: N seconds. If you want short slides but full video clip lengths you need to do more editing work such as ripple-trim the out points of the video clips to make them longer.
Dan Dennedy,I never thought that it was an
Automatic editor the first video reflects a slideshow with clip duration of 8 seconds and transition of 2 seconds, the preview time don’t even reflects 30 seconds. Now, this next video (the last one previously to that issue), have a clip duration of 4 seconds and transition of 1 second and…the preview video reflects 40 seconds,plays the video clips seamlessly (I had to edited back because we need to change one image), and it was made with the same slideshow option that you seen on the first video. Although I consider your alternative a good option? what could anyone thought if that issue happens,4 days before the presentation? I know how the world runs, and if I should get an invoice from you, email me with it, but don’t give me cold responses, many people don’t even take the time to tell about our products, they do different. got it? I’ll be reading your comments!
Why do you say that? I see 30.04 in your screencast.
a clip duration of 4 seconds and transition of 1 second and…the preview video reflects 40
As long as you have enough clips and footage it can be 40, but not 5 playlist items like your screencast. That simply does not add up.
If a video is shorter than the slideshow clip duration, that clip in the slideshow result will only be as long as the video. Your screencast is a good example. Here is the math based on, I think it shows the clip duration 8 seconds (hard to read) and transition 2 seconds.
5 clips * 8 secs - 4 transitions * 2 secs = 32 seconds. So, why is it only 30? Because your video clip #3 is only 6 seconds long. So, subtract 2 seconds and you get 30.
Next, you changed clip duration to 4 seconds:
5 * 4 - 4 * 2 = 12 seconds, which is what you got.
Dan is correct, and I agree with him. There are better softwares for slideshow generation which are also lightweight. I used one because the one that shotcut has is slow and laggy, I would DM you the name if I remember it.
What length of video are you expecting?
It appears you have already made 2 other slideshows clips.
#3 06:04 (6 seconds, 4 frames)
#5 26:23 (26 seconds, 23 frames)
My guess on what you’re expecting, and I may be 100% wrong.
Using the slide show generator with all 5 clips selected, it would inject clips #1, #2, #4 at 4 seconds, thus leaving the videos of #3 and #5 at their respective video length.
What happens when you use the slideshow generator with your 5 clips, it forces your video clips to just 4 seconds in length. In the generator window, it shows the total length when you adjust the length.
In this screenshot from your video, the slideshow generator shortened both video clips to just 4 seconds with 2-second transitions.
You would need to open up the saved Shotcut project (MLT) file, change the image out, then use the slideshow generator.

This is exactly what I did the first time, and it’s reflected on the second video I posted, you’re not wrong you put heal on the blister, it’s itching me, and what you’d said
is what I also see, and what wasn’t happening when I made the firsts slideshows.
Ideally that would it be a pretty nice, intelligent, and smart solution ever, however when I deleted shotcut from the registry, I also deleted all shotcut files, to extract back V25.01.25 on the pendrive, and start over ( where were you been previously 
with that solution?). when I noticed that I hadn’t the result I expected, as the first slideshow of the second video , and honestly the whole thing isn’t just the 3PNG’s and the 2 MP4’s, it’s like 19MP4’s and 26PNG’s, and that’s why I decided to use the slideshow generator as the first time ,as you said here:
definitely as happened in the second video I posted of the first editions.
Now…what, should I do? in your experience as a highly qualified shotcut editor as I know you are?
The MP4’s are a set of PNG’S at a fixed duration and transition time way different ,than the presentation PNG’s at 4 secs duration, what I expected, happened in the second video I posted, and that doesn’t happened in the first video. As it looks now? the Slideshow generator took the MP4’s as PNG’s and set time on them, took the MP4’s as a PNG Item instead of as a video clip, that wasn’t like that previously to V25.03.29 . Now as the Creator of the software? better code so the slideshow generator respect the formats of the files, and set time just on the PNG’s, leaving the MP4’s as they are, or…Alternatively record a video managing the MP4’s properties on the Timeline so they playback along as they are, and seamless ,to download ( but not doing it as if you have fire on your seat). a whole community of users will be highly thankful
You have two options.
-
Recreate your slideshow with the generator from scratch by loading them into the playlist first. Save the project file. This way you can easily edit the order of images in the playlist.
-
Load all of you current clips into the timeline, and edit the 3 images you need. Save the project file.
This is what the Timeline is for.
The Slideshow Generator is to facilitate working with multiple images at one time. It might be something as simple as 40 images, or something complex using thousands of image files, as you may need with a timelapse video.
