Man... It's been 7 versions already, and there is still a single video archive (Sissy3) that's 1.42 GB.
This doesn't make any sense. It's only 2 minutes of a girl speaking. There are other videos in the game that are even on the same resolution and length (Sissy) and it's only 15.8 MB. Even the excessive quality "what day is today" videos occupy less storage space per second.
Please, change/compress it. There are other ways to do it besides simply making it WEBM. There are many softwares that you can use for it, including Format Factory, which is free. The best way in which you can do it, I think it's obvious, is changing the video's bitrate. The problematic video bitrate is over 95 Mb/s, and this is higher than any 4k videos that I downloaded through my life. Make it 1024 Kb/s, but if you really want absurd quality, make it 2400 Kb/s, or 5000 Kb/s (Even 10 Mb/s would be less weird); it doesn't matter, as long as it ends up with a size that's not so brutal and non sensical.
This will be something good for you, for your game and for your players. The other archives aren't like this, and all videos are WEBM, so I doubt you tried to go through the route that is "this is an extremely niche product in which everything is of extreme archive quality in lossless format". Also, I may have not heard what the girl in the video is saying (I weirdly prefer porn to not have audio), but I doubt that she is saying "And you will jerk off while knowing that this video is occupying an absurd amount of space in your device. You could be using it to other things, even other porn, but you are so much a beta boi of mine that you are using all this GBs for my video only. Now cum! Cum while thinking about how system heavy is the video of the girl you simp for!".
Oh! And this "reduce the bitrate" is just an idea of mine. Maybe there is another way to make it better that I, mere user, don't know about.
