Information on RAD Video's KB2i Bink 2 Revision & Assistance

[MaskNinja]

Hi all,

I'm looking to research the KB2i Bink revision add custom FMVs to games made in the early 2010s. A roadblock to this is that almost all of them use Bink 2, as is industry standard. From around 2018, RAD made the KB2j revision compressor and then in 2021 they released the KB2n revision for Unreal Engine, essentially free for all. I'm looking to see if there is any information on a KB2i compressor from any source code or something. I've dug into around 6 or 7 source code leaks by now, and couldn't find anything. Cyberpunk 2077 had the KB2j revision in there (2.7J), but I haven't been able to find any more compressors, let alone the KB2i compressor. My searches are not the most extensive, but reasonable, however, do doubt it being in the list below. Due to my low disk space, it is difficult to download more leaks, although I have new leads. It is currently not possible to reasonably get videos compressed with KB2n/j to work in KB2i.

I'm wondering if anyone here has any information on a leaked compressor (as far as I know, I think, some 2.5 variant) which is revision i or leads on someone who does. I do know somebody who has it, but due to their strong refusal to assist, I have been unable to talk to them further. Note, I am not directly asking for a codec, just for stronger leads. If moderators do not approve, then please remove this post accordingly.

I'm now going to give you a list of game source code leaks which don't have Bink 2, from memory, though there are some more not on the list (and all the rest which don't as I have not searched)

Saints Row 4, GTA 5 (December 2023), Crysis 3, The Witcher 3, Thronebreaker, Insomniac (2.7m found), H4LT's leak (unlikely anyway), some of Nintendo's gigaleak, of which I could not find all of, Halo's "Digsite" leak and Gwent.

Gwent, The Witcher 3, Thronebreaker and Cyberpunk 2077 are all part of the "funnytorrent" leak. I checked the Xbox directory as well.

(Edit: I would like to clarify 2015 is likely KB2j, due to this page changing my past assumptions, due to it stating Hades has 2.5 and can read KB2j's format correctly, implying the bitstream is quite similar. 2.4d/e is still very likely KB2i, as Forza Horizon 2 is KB2i and was released in September 2014.)

I also have a very "alpha"/incomplete KB2a-i type codec I have possession of; it is definitely not perfect and has some issues, but if anyone would like it, feel free to reach out to me on Discord. The occasional frame looks like this. I'd like to give a shout out to atom0s, whom without that reference to NihAV this codec would not exist, and Kostya Shishkov, for his work on reverse-engineering Bink 2.

Edit in May: I have great progress on the encoder! I think I will be able to release a compiled binary by the end of the month; cheers everyone.

Cheers all,
