Embedded MLT file loses transparent background

[pmmvideostudio]

Hello, I apologize, but I am uncertain what I have done—when I insert an HTML file into the project as an image, it is no longer transparent. Where did I go wrong? Thank you for your advice.

What do you mean exactly when you say: “when I insert an HTML file into the project as an image” ?

when I insert an HTML file into the project as an image,

Hi @pmmvideostudio -are you using the new feature Image/Video from HTML from the menu File > New ?

If so, the generated AVI WILL have transparency, if it’s indicated in the HTML - BUT to see the effect, you need to put it on track V2, with a video or colour clip on V1, because V1 alone you won’t see the transparent effect.

There was a discussion here recently:

Neon Flux HTML template

I made another template: Digital Wave effect (Video) JR.zip (1.6 KB) Original CodePen by Ashish Ranjan. Observations: This is the original effect in Codepen: [Digital Wave 01 Codepen] This is the effect in Shotcut, with the text changed to “Shotcut wavy text”: [Digital Wave 02 Shotcut wavy text] The effect is faster (as @musicalbox mentioned in an earlier post): Also it seems to slow down at the end, and it comes out smaller. On the whole though - it’s fabulous. This is ingenious! Big …

Hope this helps.

Image/Video From HTML Generator

Choosing Image/Video from HTML from the menu File > New or a toolbar New Generator button shows this in Properties: [image] This can be used to create something like the text in this image: [Olivia-Newton-John] This requires Google Chrome or Chromium. It was added in version 25.10 Please see the stock Presets for examples. It defaults to a transparent background! The stock presets also demonstrate a template facility for up to 3 lines of text. You can make your own templates by using %1, %…

If using that, the most common problem is that your HTML or CSS is setting the background color (usually on the body element), which overrides what Shotcut writes. To fix it, do not do that. None of the presets do it. Of course, it can also be that you set the background color within Shotcut.

Thanks for the quick reply, but I’m so unhappy with this problem that I wrote HTML, but I mean MLT. The attached video shows the problem, which only started today. I’ve been using this method of inserting MLT shots for several years, but only today did all MLT files become opaque after being inserted into a new project. Thank you, and I apologize, I am really just a user and do not understand your IT language at all.

This is a bug in the newest version. So, simply export the MLT with the phone as a video with an alpha channel and use that. Choose an export preset from the alpha category.

@brian Can you look into this please?

I just found another workaround (at least it works for me)
Just add an Alpha Channel: Adjust on the MLT clip.

@brian Can you look into this please?

I reproduce this with 25.11.2 (The latest release)

I do not reproduce this with 25.11.26 (The latest daily build)

So I guess it fixed itself? Can someone else check to make sure I am not cRaZy?

@brian

Can someone else check to make sure I am not cRaZy

Still there for me in 25.11.26
I’m on Windows 10

Thanks for checking. I see now that the latest build still fails when the processing mode is “Native 8 bit CPU”. But the other processing modes work. I’ll look into it.

Thank you very much for looking into this. I thought I had unknowingly changed something in the program settings. How long do you think it will take to fix this? Thank you to everyone in the community for your willingness to help and for the consistent development of the program.

[pmmvideostudio]

Thank you for the detailed instructions, which even “I” can understand—it works great.

[brian]

This is fixed for the next release.
