Is it possible to fix not aligned photos manually?

[photoscan_user]

I have UAV flight and in some parts of it photos seems not aligned, so point cloud have holes in this part.
I have inspected this problem in Tools->Tie points->view matches and seems 'bad' photos have small number of matches about 800, other 'normal' photos have about 4k, I have tried to increase number of Key point limit and Tie point limit in in Align Photos settings but this don't help much.

What are possible reasons of such problems? How to fix this problem? maybe it's possible to fix not aligned photos manually?

Also it's strange but when I move photos that are not aligned to separate project and do Align Photos there most of them aligned ok.

Hello photoscan_user,

Do the aligned and not aligned subsets have any tie points between them?

How to check "tie points"? As I said in Tools->Tie points->view matches these pairs of photos have matches, but less then other pairs.
