Not as many as Israel since though.
The involved actor who could clear things up doesn't want to. If they don't want to, I take it that it wasn't very important to them.

There are dozens of sites collecting footage that Hamas itself put out during the attacks. There are hundreds of witness accounts. There are countless news articles from reputable news organizations corroborating all these accounts.
If you're honestly looking for the truth, it's not hard to realize what that it is.
While I still think Israel is making the same mistake we did after 9/11, these videos help me feel a little of the vitriol fueling the IDF's actions.
It also shows Hellfire-burnt bodies at Nova and seems to claim Hamas killed them.
Could you be more specific about what footage there is so important? I mean, there were obviously civilians who were killed by palestinians during that day, which isn't surprising or something I contest. But sites like that and the documentary I've seen, what they show isn't a lot, it's nothing like the torture and arbitrary detention and murder Israel has been engaged in for decades.
It shows some indiscriminate killing, for example throwing handgrenades into rocket shelters.
Soon after October 7th there was a lot of video material circulated, claimed to be from Israel but which was really cartel snuff and similar. If you have some material you are sure isn't in this category then I'd like to see it.
