Stitch line vertical offset between front and back

Happy Monday all!

 

I am seeing a vertical offset at the stitch line. It appears in the near focus field, and as well at infinity. But oddly enough just a little higher in the frame I do not see a vertical offset just another foot further from the one below it.

 

Any tips on how to remove this? I'm looking to use Fuison around sailboats, and they have lots of straight lines in the frame. Having these vertical offsets hurts the shots. 

 

Pretty cool otherwise. 

 

Thanks!

 

Bill

Re: Stitch line vertical offset between front and back

Hey Bill.

That shot looks hilarious.

 

I'm wondering if the stitch line is more obvious in that area due to a water drop on the lens?

I know from GoPro's website that Fusion doesn't like stitching under-water, and the same stitching issues may show themselves with water droplets. I'm not sure though, as I do not have any experience with the Fusion.

Re: Stitch line vertical offset between front and back

Hi @hpictures,

 

Please try to reposition your camera or make sure there's enough distance before any object appears on the camera. 

Please also check if there is no water droplets. 

 

If there is no water droplets and issue still persist please try to contact our customer support team for assistance. 

 

They are available via phone or chat: https://gopro.com/help/ContactUs

Re: Stitch line vertical offset between front and back

Thanks Jay, Josh...

 

In the frame from the clip I picked as an example, there were water drops. But at the head of the shot when there were no drops, the stitching error is still seen. Even in the still photos I took with Fusion during the palcement testing it was present.

 

As for placement - I've seen - at least I think I've seen - lots of shots inside vehicles where there are things closer to the camera than I had. Can you point to any best practices for camera placement to look over? If there are general sensitivities for placement, that would be a good thing to know.

 

Is there any kind of field testing you can do to determine if there is an lens alignment issue in Fusion?

 

Thanks!

Re: Stitch line vertical offset between front and back

 

Hi @hpictures,

 

 

I would suggest to check or pair it on your phone so that you'll see realtime the result. 

 

Also make it a habit to place your fusion's front and back to the direction you really want to focus on. 

 

for example the sun. If you want the sun to appear as whole tilt your Fusion's front or back towards the sun and not the top of the camera where in the front and back lens can capture the rays or sunlight. 

 

Also you can check this video https://www.youtube.com/watch?v=I4KOwInGRuY&t=265s

 

Regards,

Re: Stitch line vertical offset between front and back

Thanks Jay,

 

Good information on the clip. I'll put together some tests like the YouTuber did to work on placement.

 

When I set up the shot, I was using a tablet as the monitor. What I saw in the tablet pic was worse than what I saw rendered out in Fusion Studio. At the time I was pretty surprised. I tried tilting the camera, and panning left and right to try and hide the stitching in areas further away from the camera. But being a boat, there's lots of lines at least on one side of the image. So for this placement, it was sort of a no win. I took the cruder stitching as a result of d.warp not being used in the wifi signal to the tablet. Right?

 

On a later placement at the stern of the boat, there was clean areas with out lines on either side of the camera. Just water, sky, and land with some other boats passing, or being passed. So far, that clip is very clean.

 

Thanks!

Re: Stitch line vertical offset between front and back

Hello friends, how are you?

 

I wonder why in my seam after processing at Premiere 2018 you get a black ball underneath and over at the video splicing?

 

Does anyone have any tips for this solution?

 

 

 

 

Thank you.

Re: Stitch line vertical offset between front and back

 

Glad to know that @hpictures,

 

 

@marcoarm, Mya I know how did you stitch that?

And is that a GoPro Fusion Clip? 

 

Have you tried using GoPro Studio and check if there is the same output?

 

 

Thanks,
