I realize this may be software specific but I'm wondering what controls which photo of a slide show creation shows when the video is posted on public media (sitting while not played) ?
I create a slide show using Vegas Studio and looking at the file (in a file manager) sitting on my HD it shows the 1st photo of my slide show which to me would be normal.
But when I post it on public media, when it's seen in the post (not playing) it shows a photo from middle of the slide show ??
Is this some sort of proprietary data within the original photo file that public media engines are searching out for display ??
Curious what's behind that and if there's a way to control it.
