Ratchet & Clank Rift Apart
For the movie files you can use bink2 plugin with a chunk size like c1gb. The videos are just stored as plain text. You can see the bink2 file headers "KB2j" with HxD but I don't know how big the biggest file is actually. However I guess c1gb should be enough.
Code:
c256mb
Compressed 4 files, 4,269,568,000 => 3,891,106,223 bytes. Ratio 91.14%
Compression time: cpu 1.83 sec/real 144.25 sec = 1%. Speed 29.60 mB/s
All OK

I guess you can find out the biggest file chunk using xtool verbose mode with the bk2 plugin, but not sure.
