This game is great, but I think all the videos in A Succubus Is Born should have sound, without exception. To achieve this, you should convert the MP4 videos to WEBM, as this would save space to add more quests and videos with sound.
The blowjob scenes should end in sex, and I think that while exploring the city, the character should find new places and have new interactions.
I choose to remove the sound from some videos. E.g. if there is music, a voiceover or it is extremely bad quality. Trust me, you don't want sound on some of those clips. It has nothing to do with them being in mp4 or webm format.
As for the size, I am already compressing all videos using Handbrake. There is nothing I can do to reduce size further without a significant drop in quality. And uhh, quests do not take up any size.
And again, converting to webm would not help decrease video size
"The blowjob scenes should end in sex".
Blowjob scenes during combat or events/encounters?
If events/encounters: Most of these are created from videos that does not contain sex. Also, some are only available BEFORE sex is unlocked. So no, they should not end in sex as it either is not possible or does not make sense, heh.
"...I think that while exploring the city, the character should find new places and have new interactions."
I think so to! It just takes time to create that content, you know
