In Bucha, this is definitely a staged fake of Ukrainian propaganda, filmed on professional film equipment.
Here is a video of the cleansing of Bucha by the Ukrainian police, there, for the whole time, a corpse in military uniform flashed in the frame once, there are no civilian corpses there. The decision to provocation under a false flag was apparently made by Ukraine later.
I think you're being fooled, just like when you were so sure that the reason Russia hadn't surrounded Kiev was because they wanted to let civilians escape and only a fool would think Kiev had any chance against the mighty Russian military.
There are satellite images from March 9-11 that show many of the same bodies on the road in the exact same positions that were filmed after Russia retreated from Bucha a few days ago.

Of course, not as simple as painting muddy pixels on satellite images, but nonetheless.
