.Png and .Tif files with alpha channel doesn't work

Filter is just a name. It’s still a text tool.

v2???
I use version 17

I [think] I do, but it is not necessary. You can have all kinds of text anywhere as an overlay, even with transitions for the text.

It is not a tool because it doesn’t work independent, it is a filter that needs to be applyed into any clip.

When i said V2, i meant Video track 2. I explain better:

Text in shotcut, needs to be applyed into a filter, it is not a clip by itself, so if you need to put a watermark, for example, or you want to put some texts changing independents over the clips of video.

With a transparent clip in V2, (video track 2) over the video clips (that are in V1 (video track 1), it is the fast way and sometimes it is the only way to do some kind of things with the text. if you need it with different duration than the video clips.

If you use to work with any other NLE, i think you`ll understand me.

Look, I’m not going to argue semantics with you, and if your method works, fine. But it’s not necessary to import a transparent PNG bitmap into a 2nd track to apply a text overlay [with a transition] exactly where you want it. There have been a number of posts explaining how over the last months including video tutorials from other members.
The fact that you are having ‘issues’ with your alpha channel PNGs should be enough to motivate you to seek out this other method which doesn’t require any PNG [or tiff] imports

And thanks, I am fully aware of other NLE’s… :slight_smile:

I agree with @manuzapa the transparent png solution is from far the easier and Quicker way. You can remove it quickly, move right of left at the end of your work if you change your mind, make it inependant of clips, Copy /paste and modify…

I did mine with Gimp.
Maybe you need to limitate it to 8 bits.

It’s already 8 bits.

And I’ve had transparency issues with png’s in Shotcut as well. I like to add text as png because of the freedom sometimes. Normally to add a transparent clip I use File > Open Other… and create a color with full transparency there. 0x00000000.

A png is not just a png. You’ll know when you’ve done enough OpenGL C++ programming using various supports libs, custom file loaders etc.
Just like RGB is not just RGB especially when you add alpha. ARGB or RGBA? ABGR? 8 or 16 bit per color or what? And how do you split 8 in 3? Does the green and red get 3 and the blue 2? Or another way? Etc.
People seem to disagree. I have had some weird issues with Photoshop pngs in particular. At one point I simply had to open everything in GraphicsGale, set the pixel format and File > Save as…

Will try tonight with my PNG and will send it to you for testing purpose…

Edit : here they are .Fonds.zip (1.2 KB)

Working OK on Feb 17 version. I’m updating to verify
Confirmed that it works on march version’s too.

Thanks a lot to everybody for the fast answers!!

And Keno40, Grazie Mille for the PNGs.

I am an editor in TV, i used to work in avid, final cut, premiere…

But for a seminary with student’s project, I need this because it is a free software and multiplatform.

For a lot of reasons, Shotcut is a wonderful project, and a nice and romantic idea, and I hope someday it will become a great program that many people use.

But right now it’s too young and half-finished software. And if above, we add to this that I already have the head very squared for the professional NLE systems… This seminary is being a pain in my ass !! Ahahah

Again, thanks for the help to everybody !!

Good point.

Confirm for version 17.03 and 17.04
I have the same problem

Transparency does not work even if I create a color open other -> color and then create a color with alpha channel
There is not transparency at all.

Which OS?

I use W10 Pro and have the most recent Radeon drivers. No problems here with Alpha transparency here.

I have windows 10 installed on my pc.

Probably it works on your pc because you did some upgrade and previous install leave some good libraries, but with fresh install here does not seem to work at all…I just suppose something like this.

Doubt it. I suggest you check for Windows and display driver updates, Scan for Malware and run sfc /scannow from elevated cmd. Always good to cold boot your PC if you don’t already.

the computer is clear and everything is updated.
It does not work neither from warm or cold boot.

Does alpha transparency work in other applications?

Can you try with the png I posted above?

Works fine in April version.

I had the same issue. So I tried creating a new project, and everything works as it’s supposed to. I tried to look through the mlt files, but could not find any clear differences (today is the first time I’m looking at an mlt file, so I might be missing something).

I run Win 10 64, with 16 gig RAM, and a GTX 1060, both projects used the same clip, and I have more than 9 gig free, so I don’t think this is a performance issue.

i had the same issue too and was doing inkscape svg or png if i remember correctly, but gave up and used the text filter instead when i was editing some videos some months back

what are we suposed to use to get non-buggy/glicky transperant alpha images to work?, most people will use inkscape due to its open source nature

people, post all your png/tif transparent alpha image to get others to test

Never used it. So I just downloaded the latest version and created a PNG bitmap with alpha transparency.
Works fine in Shotcut.

okey then either inkscape or shotcut has fixed the issue in the last months, thanks for checking :slight_smile:
