Can an Image Sequence be used as an Alpha Channel using Mask: From File..?

Greetings all,

I have been trying to do some simple compositing, and have exported my 3D renderings as separate RGB images and alpha channel.
I can import all of these in Shotcut no problem by ticking the ‘use image sequence’ box, to place them in the playlist, so I know they work.
But when I try to apply my alpha channel sequence using the filter ‘Mask; From File’, it seems I can only load either a single image, or a video file, but not an image sequence.

Am I missing something, or do I just need to convert my alpha channel’s image sequence into a movie format to use it this way…?

Cheers

Derek

I don’t think the image sequence can be used with mask from file. Export the sequence with one of the alpha exports.

Thanks for the reply.

I’m just learning, but I think those alpha export optins are to export a movie with alpha channels embedded, if the movie already has an alpha applied to it.

Cheers.

Try it. It might work.
