Hello,
When you say you want someone to teach you how to do it, do you want to use free software's? Paid ones? Plug-ins for existing software's (After effects, Final Cut etc)?
There are a few options available at the moment for stitching, some are easy but expensive others a little cheaper but more time consuming.
Let me know what are your thoughts on it. so I could help you better.
Kind Regards,
Fabricio Morato
