Hi, I'd like the option of watching these videos without my headset. Some of the videos look better than others when viewing in Chrome. Many still have a warped image, especially when the subject gets closer to the camera. Is there an easy way to unwarp the distorted image on SLR videos for a better flat/2d experience? Thank you!
how to watch old SLR videos in flat/2d without the warped image?
cd ~/Documents/LOCATION
ffmpeg -i "NAME.mp4" -filter:v "v360=input=hequirect:output=flat:in_stereo=sbs:out_stereo=2d:d_fov=125:w=1920:h=1080:pitch=0" -map 0 -c copy -c:v libx265 -crf 18 -pix_fmt yuv420p flat.mp4
for file in *.mp4; do ffmpeg -i "$file" -vcodec copy -acodec copy -tag:v hvc1 "${file%.mp4}_converted.mp4"; done
jimboneshoba The website player has a button (left of the gearwheel) by which you can switch between two modes, one of which should look more warped than the other. If you have found this button already, I think there is nothing else.
xeddin1 Hi I tried this and the resulting video is still warped and zoomed in showing only part of the frame
jimboneshoba you will have to edit the values based on preference

As far as I can tell, there's no way to get a 180 degree video to fully display onto a rectangular viewport without distortion, your best bet is to zoom in until the field of view is in the vicinity 60-90 degrees (at which point you'd technically be seeing less than a quarter of the whole scene).
It's kinda like the map of the earth, we display it as a rectangle but only after distorting it severely, especially near the north and south. There isn't a rectangular projection that is distortion-free.
jimboneshoba bro just screen record your favorite scenes, favorite parts, thats what I normally do, I'll keep a few on my phone to watch later.
