How can we change the video to image ratio? Currently it favours images way too much and we barely see videos...
You can't ATM, personally I feel like videos should be more rare than images. Video's have a way larger filesize so I think it's fair to say most people will have more images than video's. I'll give the ratio's another look though. Also while it may not be as apparent, video phases so to speak should already last longer than any specific image phase. If a video is being displayed there is a large chance that it'll stick to videos rather than images.
I've adjusted how the next images/videos are picked. From now on having more of something will make it more likely to appear. This means that is you have 100 videos and 50 images the chance of you rolling video will be higher than if you were to have 50 videos and 100 images. This still doesn't mean that you'll roll in the same rate as your own ratio but it's closer than before.
