Hi, I recently downloaded some free pack stock footage and when I took a look at it I realised they were .tiff sequences. Now I really don’t know much of premultiplied alpha but I’m sure that’s my problem here: you see whenever I try to open the .tiff’s in any sort of application they show a black and white frame that looks like an alpha matte for the supposed picture.

As I said I don’t know how to deal with premultiplied alpha, is it something I can handle in blenders VSE, compositor or something?
And if it isn’t premultiplication that’s the problem, then what is it?
Thanks
