Working with Image Sequence in Sequencer

Hi! I am trying to use a sequence of images in the Sequencer and the only method that has worked for me is with the Image Media Source asset.

The problem is that I am working with a work team and every time someone opens it, this “Reimport assets” popup appears asking to transform the .pngs in .uasset, and when transforming the images to .uasset the sequence stops working.

Is there a way to prevent the popup from appearing on all computers?

Or is there some other more ideal method to work with image sequences?

(The sequence of images is quite long, they are around 60 frames of 512x512)

I think you’re better off with a 4k texture flipbook if you sequence is that size you posted
