I am glad to see that whoever released this blurred out almost everything in the OSD, even if it makes my identification harder, as it helps keep sensitive information private private, but I’ll reiterate some concerns that I’ve posted earlier that maybe there should be some sort of standard unit in the military that does the censorship before release.
First point. Some of the numbers “leaked” around the edge of the blurred area. Probably nothing critical, but I’m sure that it’s not intentional.
Second, I don’t know how hard it is to reverse a blurring operation. I am pretty sure that the censoring software isn’t deleting the area in question and then regenerating it fully using pixels at the edge, because that flashing bit that I assume is a “low battery” warning shows up even with no pixels on either side of the blurred area visible, and doesn’t “snap” from one side to another when the blurred area shifts from exposing a few pixels on one side to exposing a few on another. And if that’s the case, it may be possible to reverse some of the operation.
If Ukraine is using a method that isn’t adequately-hardened to censor these, and is using the same approach on many videos, then Russian intelligence can potentially restore that information.

Third, this, like a number of videos I’ve seen, look like they’re from a cellphone camera of a drone display. That’s not the end of the world, and I don’t know if all those drones have some way to export video. However, I’d think that if they don’t, Ukrainian intelligence may want a way to archive the footage that they’re taking, because all of this footage near the front is probably interesting for all sorts of analysis. And if it can be exported directly from the drone feed to be released, I’d think that that’d be preferable, because it also means that there’s no risk of information being leaked from other sources, like background sound from inside an FPV base (“nest”?), which is something that I’ve seen sometimes, thought not in this video, or video including background shots of the FPV base, or reflections.
