It is a way to remove fisheye from a gopro or yi 4k action camera without loosing quality or without replace the lenses ? (regarding the video)

  • \$\begingroup\$ Video is off-topic here, it's a question for video.stackexchange.com. Anyway, I suggest you make some research on the subject, I am pretty sure that you will find what you are looking for, using your favorite search engine with "video processing red eye". \$\endgroup\$

  • \$\begingroup\$ @Olivier OP wasn't asking about red eye, he was asking to defish the wide angle. However, agreed on off-topic. \$\endgroup\$

  • \$\begingroup\$ Yep, I don't know why but probably at the time of writing my comment "red eye" sounded better than "fisheye" :) \$\endgroup\$

  • \$\begingroup\$ I'm not sure about removing in post, but you can adjust the settings on a GoPro before you shoot, narrowing the field from wide to normal \$\endgroup\$

You can, in theory, add supplemental lenses to change the field of view — however this almost inevitably affects quality. Supplementary lenses tend to be low quality.

You can crop the image/video in post-processing — but this reduces quality (at least in terms of number of image pixels)

Replacing the lens is certainly the best way to get a narrower field of view without reducing quality.
