I change my settings to try the 5.3k 8:7 Wide mode on my setup with GoPro Hero 11 (as already on the drop down) and I’m unable to have a good alignment at the stitching step.
P.S. I just remarked that in Actionstitch it’s configures “full” for the format. Is it the same as Wide as my gopro is configured ? Wide is the only setting available at 5.3k 8:7.
I can send you another video grab of the checkerboard pattern.
I’m curious if the generation of the configuration is a manual process or if it could be made a standalone tool available to the end user ?
The calibration data is ok. For some reason the stitching algorithm can only find feature points near the bottom of the scene causing the top half to be off by a lot. A workaround is to use the manual stitch feature, as shown in this screenshot:
I’m curious if why you’d choose 8:7 rather than the 16:9; I’ll try and experiment to see if I see a difference but wondering what I should expect. Thanks in advance!
Not sure if there was an update to the GoPro 11 stitching algorithm, but the last few games I have shot, the centerline hasn’t been lining up during stitching. It seems to look okay to the naked eye when stitching, but the finished video is always a little off. It has been fine for the last 15-20 games I have captured but now looks like the attached file. I thought it was just a fluke, like misaligned cameras during the previous weekend, but this last weekends game looks the same. Any ideas? I have NOT tried to manually re-stitch these as it isn’t a MASSIVE issue. Just thought I would bring it to your attention.
There hasn’t been any changes to the stitching algorithm. It appears from the screenshot that the bottom of the centerline was stitched perfectly. Perhaps the algorithm picked most feature points from the bottom half so the far side wasn’t stitched well. If that happens again, switch manual stitching to see if that helps.
So I just had another game this past weekend and the same issue is happening, the stitch is either good on the top half or bottom half of the screen. So I went ahead and did a manual stitch, which worked for lining things up for the most part. After it was done processing I got a codec error in the normal software I use to check playback (see attached screenshot). I have never gotten this error before and I figured it must have something to do with the manual stitch. No idea why, but I went ahead and re-stitched it using the auto settings even though it wasn’t lined up perfectly. Now that file is also giving me this error. All previous games I have stitched have played in any software without issue, and now this is happening. Any ideas or things I should check? I didn’t change anything on my end about how I go about using Actiostitch so no idea what is going on!
Could it possibly be a resolution issue? This last game has a resolution output of 7700x3800. Most of my other games don’t go over 3400px tall. The default program I use for simply checking playback on a video is Media Player in Windows 10. But it also won’t play in the standard “Movies and TV” app. It WILL playback in VLC though.
I am still have issues with everything lining up. It gets CLOSE but not as good as it once was. No idea why. I haven’t changed anything about how I shoot or the mount/tripod/etc. Still 8x7 ratio at 30fps. Stabilization is turned off. It is so strange.
As for resolution limits, it turns out it isn’t the height that is a concern, it is the width. 7700px is too wide for the default programs. Works fine online in your player though. After doing a few tests, I can go as high as 7650px wide without issue. 7680 is too wide (so of course 7700 is as well). Height wise I was able to go up to at least 3800px without issue as long as the width was 7650px or less.
