Batch photo stitching, 1048 pictures with a right an a left lens

as i don't see a PS action approach walking through such an alternating file name pattern in a folder, i think your task may be the perfect job for PTGui's (https://ptgui.com) batch builder and batch stitcher. just create a stitching template for one image pair and let the batch builder generate a stitching project for it which is then handed over to the batch stitcher. these functions are highly configurable. this video should be a good starting point for you: https://www.youtube.com/watch?v=p2XGBfASMi0 - i used both functions together to create 70+ spherical HDR panoramas straight away from a 2500+ file lightroom export into a single folder. this whole process was running completely unattended and showed flawless professional results.

How would you combine them manually?

Just attach the images to your forum post as you did previously, or post a download link to your CC files, DropBox, WeTransfer etc.

How would you combine them manually? In left/right pairs?

Can you provide samples of say 3 sequential sets of left/right image pairs (6 photos). You can make them half size if you like it that doesn't affect the process. And also provide 3 combined examples from the same sets as a guide to what you wish to achieve.
