Questions about how to improve the stitching effect #285

Dear author, hello. Thank you very much for your labor achievements. Through experiments, I found that the jigsaw puzzle effect of this project is indeed better than that of other projects.
However, I also encountered some problems. When I used a series of data frames (from drone horizontal shooting videos, one frame per second, at a very slow speed) with a resolution of 720x380 and the scene was relatively simple, the stitching effect obtained was quite good.
Then I used my iphone to row a video horizontally on the bus. There was no jitter, the resolution was 1920x1080, the image had more details, two frames per second, the speed was relatively slow, and more than 90% of the features were repeated between the images. However, the stitching effect was not very good, with misalignment and blurriness.
I conducted three sets of the same experiment but failed to achieve the same effect as the first set. Therefore, I would like to ask the author, in order to obtain the best stitching effect, what kind of shooting video should I provide, what kind of interval frames should I provide, and is it better for the video resolution to be higher or slightly blurry?
Looking forward to your reply.
