Hi Rakesh.
Thanks a lot for reaching out to us.
Firstly we need you to give us further information about your problem, Could you send us screenshoots of what are you doing? it is important to know every step. We also need to know about how you did the recording process, because sometimes stitching problems came from there.
Appart from that, Mistika VR and Mistika Boutique, have presets designed exclusivly for KanDao footage, which make the stitch automatically, Have you tried it there?
Here you can see a tutorial which can maybe solve your issue.
Regards.
Nicolás
