There is no "Movie Maker 17" in the Vegas or Magix product range. Exactly what programme are you using?

Wrote the name wrong, trade "Maker" to "Studio", so "Movie Studio 17"

As additional information, what is happening is:
if you put the viewer in any part of the project, the preview show a black video (1st print), but if you change the size of the preview, it does show THAT FRAME (2nd print)

The problem is when I try to play the video it returns to black

Ok thanks. Are you using the same type of source files on your timeline? Is it just some that give problems, or all file types. Where do problem files come from? Post media info on one of these files. Instructions here https://www.vegascreativesoftware.info/us/forum/faq-how-to-post-mediainfo-and-vegas-pro-file-properties--104561/

PS. Your links don't work. "That page doesn't exist (404)". Best to post images direct to the forum using the upload button.

I uploaded the images in the forum now.

As for the problem, any type of file (movies and still images) aren't showing in the program. The prints that I posted here are using the "Example" project that comes with the installation (but any of my older projects aren't showing in the preview).

Just to add some information, the audio from video files and just audio are working just fine (and I ca even render the final project without any trouble, it renders the video in the final file, it just the preview that isn't showing any image)
