Videos seem to be transparent ?

Hello,

I have a existing .cptx-file in which I want to import a Video demo. I tried several ways to 'import' my video, but for some reason, it always seems to be in a transparent overlay of my Master Slide. This is what I did (in Captivate 😎 :

• I created my Video Demo from within my .cptx-file by clicking 'File - Record new Video Demo'. That way, a seperate .cpvc-file was made. In my .cptx-file, I selected the slide on which I wanted to show the video demo. Then I inserted it by clicking 'Insert - CPVC Slide'. Result: a transparent video ... Both my video and my master slide seem to be at a 50% transparency...

• I wanted to verify if I had the same problem when I inserted a normal video file (no .cpvc). So I published my Video demo as a .mp4 which I inserted. Result: that works out fine, but isn't very practical : every time i want to make a tiny modification, i'll have to do tat in my .cpvc and publish it again. Not the most effective way ...

• To be sure the problem wasn't caused by my Video demo-settings, I recorded a new Software simulation, which i tried to insert in two ways:

1. first following the same procedure as described here above (video demo). Result: transparent video
2. secondly by selecting the created slides in my software simulation and by copy-pasting them in the .cptx-file where i wanted to show the video. Result: transparent video...

Does anyone know what could be the problem? Is it linked to my Master Slide? But if so, why does it work out fine when I insert my video as a .mp4-file ?

Thanks in advance for your suggestions/answers!
