Fixing PTGUI panorama with EXIF Fixer

I made an equirectangular pano using my Mavic Mini2. If I use the drone generated pano and fix it with EXIF Fixer, it works just fine on FB. But if I stitch the pano from the higher res images using PTGUI, which works fine, when I try to load into EXIF Fixer, it only gives me the cylindrical option. Any idea where I am going wrong? I am setting equirectangular in PTGUI BTW.

If its the photo you uploaded I’ve just run it though exif fixer and yes it only let me select cylindrical but i was able to add fake camera data and upload to FB.

Oh and your file above isn’t 2:1 which is probably why

@milkmanchris is right: it isn’t a 2:1 width to height ratio image, so it can’t actually be equirectangular. (Even if an image is one pixel wider or taller than precisely 2:1 it’s not an equirect.)

If you really want to force it to be treated as an equirect there are two ways to do this. The first is simply to extend the image canvas so the height is exactly half as many pixels as the image is wide. Don’t stretch the image, extend the canvas. You should then adjust the position of the image itself so the horizon falls as close as possible to the vertical centre of the canvas, or you’ll get a weird bent horizon effect in the final interactive result.

The second method requires using the standalone Exif Fixer app rather than the Exif Fixer Online service. When you drop your image into the app you’ll see the metadata that will be added in the field in the lower right of the window. Where it says “cylindrical”, change that word to “equirectangular” before clicking the button to add the metadata to the image. It’s a built-in hack I included because occasionally – rarely but sometimes – it can be useful to insert ‘incorrect’ metadata.

Thank you @thatkeith very helpful

Thanks Keith. Everyone helped me fix it. I wasn’t aware of the 2x1 requirement. And I hadn’t selected the correct sub-setting in PT Gui.
